Title: Desktop Issue After Boot (Solved)

I have just built this computer and installed P8r. During installation all went as usual until it came time to restart. After clicking on the restart button the display told me to remove install media and press enter.  I did. After 20 plus minutes the computer did not restart. I ended up using a hard shutdown. I immediately restarted the computer and it started up as usual. I then went to Software & Update Settings and checked source code and both Canonical Partners and after that  I did all the update,upgrade, and dist-upgrade stuff. After the dist-upgrade I shut down completely. After about 10 minutes or so I restarted and that is when the issues started.
I always use auto log on. The first screen I see is a log in screen. (See picture) https://imgur.com/a/cFFF1
So I just rebooted and I got my normal desktop. At that point I added Thunderbird and edited my profile and added Gparted. That is it.
Over the next few days,every time after I completely shutdown, the next time I start the computer I get a weird desktop. Sometimes it is the log screen and other times is like this.

It seems that all I have to do is reboot and I go to my normal desktop.
Does anyone know how to correct this situation?

According to Phoronix, Coffee Lake CPU's with the UHD 630 graphics need a kernel boot parameter (i915.alpha_support=1) adding.
https://www.phoronix.com/scan.php?page=article&item=coffee-uhd-graphics&num=1

So open a terminal and run:
Code: [Select]
gksudo xed /etc/default/grubwhen it opens, find the line that reads:-
Code: [Select]
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"and change it to read:-
Code: [Select]
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.alpha_support=1"SAVE the file and close the text editor.

Back in the terminal run:
Code: [Select]
sudo update-grubthe REBOOT to test.

Once rebooted, can you then post the output from:
Code: [Select]
inxi -Fzagain please,



The only other option is to use the 4.15 kernel which supports Coffee Lake graphics OOTB .. the problem with this is AFAIK there's no pre-compiled 4.15 kernel for Ubuntu (and derivatives) yet with all the Meltdown/Spectre patches yet .. so best to stick to the default kernel and use the boot parameter instead.

I have done as you have prescribed. I shutdown for awhile and when I restarted P8r went to the log on screen.  (The first photo OP.) This time I logged in. It gave me my desktop so  I went right to this forum. I am going to test for awhile. I am going to shutdown and wait for a half hour or so. Just to see what P8 does.

Last evening I tested and I was greeted with a desktop like  the top picture.  https://imgur.com/a/z7iB5
 :( This morning when I started up the computer I was greeted with this desktop: https://imgur.com/a/Ynras
With that desktop I had no network connection. Audio did not load. Chromium home page would not start. I could not shutdown with ctrl+alt+delete, or through the menu, and I could not even use the terminal. I used the reset button to restart and upon completion all looked like one would expect.

After reading the link you provided I have searching around the net. All indications point to your fix. So I'm posting the grub you asked me to modify. Maybe you can see what I possibly mucked up.
grub
[close]

Also while looking around the net I found this under the Intel site: https://downloadcenter.intel.com/download/27337/Linux-Processor-Microcode-Data-File?product=126688
So I go to the file manager open the  root folder under the etc and I can't find any firmware folder. So I'll just wait for some guidance.
Title: Re: Desktop Issue After Boot
Post by: PCNetSpec on February 01, 2018, 06:16:47 am
That looks fine to me, try running
Code: [Select]
sudo update-pciidsthen rebooting.



The intel microcode can be applied through:-

Menu > Preferences > Additional Drivers

Put a tick in "Using Processor microcode for Intel CPU's from intel-microcode (open-source)"

And click the "Apply Changes" button.

Once it's finished .. REBOOT to apply the microcode.

 :(  So I have done what you have asked yet still need to reboot after a startup to get to a normal desktop.
After doing all the above I shut down and waited about 45 minutes.
When I start I got this desktop.  https://imgur.com/a/HztrA
  The gray  box is from the network notification
   Note not all the icons in the lower left panel showed up.
Upon opening the file manager folder and moving it  I got this mess. https://imgur.com/a/Cl1sq
I then rebooted and P8r went right to the usual and customary desktop.  :'(
Do you have anymore ideas?

Post by: PCNetSpec on February 01, 2018, 08:17:23 am
What happens if you boot to the screwed up desktop, then log off/on ?

Or boot to the screwed up desktop, then run:
Code: [Select]
sudo service lightdm restart?
Title: Re: Desktop Issue After Boot
Post by: Ralph on February 01, 2018, 09:01:16 am
After about 15 minutes shutdown. When I restarted I got a log on screen like this one. ( Note the imperfection)   https://imgur.com/a/cFFF1   
I logged on and it went to my desired desktop. ( note the imperfections are gone)   Remember I did not install P8r to have to log on. It should go right to the desktop.
After this is posted I will have to wait for about an hour to try sudo service lightdm restart.

Post by: PCNetSpec on February 01, 2018, 09:15:08 am
If you're ending up at the login screen even though you chose to autologin I can only assume the x session crashed (which will dump you back at the login screen).

Is there any clues in the logs at
Code: [Select]
xed ~/.xsession-errorsor
Code: [Select]
xed /var/log/Xorg.0.logor
Code: [Select]
xed /var/log/Xorg.1.log?



We could try the 4.15 kernel .. but this option is risky as it's not currently fully patched against Spectre.

i have no idea if this will help you at all...[wait for PCNetSpec, pin or other moderator or trusted user to weigh in first before doing this]...i have bootup-manager installed on my system because i was having problems on previous mint installation...(im now all peppermint on my systems)...i too had login screen coming up at different times even though i wanted direct login...(also have this bootup-manager on my peppermints as well...sudo apt-get install bum...once installed i run it and unclick "lightdm" on startup...as well as other things i do not need at startup...that was the end of my problem...as a side note i also unclicked all samba entries, as well as cups, avahi daemons etc. etc. and all works fine here including printers and other peripherals... the only things i have enabled at startup are...rsyslog...uuidd...thermald...hddtemp...ntp...and...irqbalance...just those 7 items only and everything just works when i need it...again wait for others to weigh in here since my usage may be way different than yours

So I waited an hour and upon restarting I got an all black screen with the bottom panel on the left missing the audio,network, and update icons.
On the left none of the shortcuts worked.
The menu displayed the whisker menu but nothing worked.
Using ctrl+alt+delete turned the all black screen to gray and after a time I got this screen: https://imgur.com/a/eoVGC

Do you want instructions to try the 4.15 kernel ?



Can you also explain why you say you have to wait an hour between tests ?
(does this only happen if the computer is stone cold or something )
Title: Re: Desktop Issue After Boot
Post by: Ralph on February 01, 2018, 02:48:02 pm
The short answer is yes.
When I start from a stone cold computer absolutely nothing responds. I have to hard shutdown. After a reboot everything work as you would expect.
When I wait just 10 mins. I usually see the the log on screen or something else as shown in the picture. When it is something else, I can access the internet,files,and the terminal. Most things work but my wallpaper doesn't show or any desktop icons until I reboot and then everything works fine. When I do get the log on and I log on everything works as you would expect.
It make no sense to me but in a nutshell that's what is happening. I wished I could explain it better.

This morning when I started from a cold start I got the all black screen with the bottom panel minus only the update icon. Everything seemed to work. The black screen turned to all gray after I closed Chromium. When opening the synaptic Package Manager I log in to it and gave me this error screen.  https://imgur.com/a/o5OhD

Now to the kernel update. Copied and pasted all commands, When It came time to install I got the same error as the photo above.
sudo apt-get install ./*.deb
[close]


Wow! Something new. Can't seem to update anything. Just running the apt-get update command from a new CLI throws the same errors.

[EDIT]

I'm beginning to think there may be an underlying hardware issue here .. have you tried running memtest86+ from the GRUB menu to test the RAM ?

This corruption of the apt lists could be purely coincidental (or caused by something else), but it can't hurt to run the test.

So as you can see I was able to update and install the new kernel.  I happened to notice these two lines. I hope that it won't be a problem.
W: Possible missing firmware /lib/firmware/i915/kbl_guc_ver9_14.bin for module i915

I'm going to run the memory test now. How long would you run that?
Title: Re: Desktop Issue After Boot
Post by: PCNetSpec on February 02, 2018, 07:07:02 am
Okay to fix the missing firmware for the 4.15 kernel, run these commands in sequence:
Code: [Select]
cd /lib/firmware/i915then
Code: [Select]
sudo wget https://peppermintos.info/misc/missing-firmware-for-kernel-4.15.tar.gzthen
Code: [Select]
sudo tar xvf missing-firmware-for-kernel-4.15.tar.gzthen
Code: [Select]
sudo update-initramfs -uk allif you got no errors, the firmware is installed properly.



As for how long to run the memory test .. your call, as long as possible .. but normally errors on an unstable system will show up on the first cycle through the tests.

The above spoiler is all the commands for the firmware install. I see no errors.
I have run the Memtest86 for two full passes over 5 hours with no errors. 
Tomorrow when I boot up I will see what happens.
BTW I could not find the grub menu with the memtest86+. Holding the shift at boot got me nowhere a half dozen times. Found a ubuntu site that said use the Esc which got me there but no memtest. Finally gave up and used the install media but instead of UEFI I just used the old usb setup.

Title: Re: Desktop Issue After Boot
Post by: Ralph on February 03, 2018, 09:06:54 am
Well it still is not working.  :'( :(
This morning when I started up I got the all black screen. I ran in the terminal this command sudo service lightdm restart. When it restarted I saw the desktop as it should be. I thought then that maybe we are narrowing it down.  I shutdown and waited a good half hour. This time I got the all gray screen. I could get to the terminal using the keyboard but the lightdm restart command would not work. Just saying something like it timed out. I ended up doing the hard shutdown.
I have noticed that sometime during all this adventure at startup I have seen error messages flash across the boot screen. And I mean flash. There were 3 distinct flashes of messages. I captured them. The first one is here: https://imgur.com/a/2HRQ5
If you would like to see the other two I will post. They look to me to be quite similar.
Sometimes even when it loads to a workable desktop I get errors that say the panel couldn't load either the keyboard or pulse audio. Here's a snapshot: https://imgur.com/a/C7SqB

I have no idea what's going on. It seems the newer kernel is no better than the older kernel. I really hope you can come up with something.

Have you tried any other 16.04 based distro on this machine ?

Where did you get BIOS version 1.70 ? .. this:

Title: Re: Desktop Issue After Boot
Post by: Ralph on February 03, 2018, 10:26:33 am
I was thinking about it but no. Since finding Peppermint I have stuck with it since 4.

That bios version came from using the bios updater over the network from within the bios itself.

I went to install Peppermint 8 respin. When I booted to the usb install media all those errors showed up while loading. I know for a fact I checked the Md5sum to verify the download following the directions from the Peppermint website.
I decided not to install the respin and instead installed P8. No error messages. I did all the usual and customary updates and rebooted. Again no errors. The only errors if they are errors is during the dist-upgrade I saw this:
warning: file-aligned section .text extends beyond end of file
warning: checksum areas are greater than image size. Invalid section table?
I don't know if it means anything or not.
I will test tomorrow to see if all is right. Here's hoping.
Title: Re: Desktop Issue After Boot
Post by: Ralph on February 06, 2018, 10:40:04 am
Here's an update of this issue which I seem to be the only one having. Peppermint 8 reacts the same as 8 respin but without the errors when I start to boot. Following the suggestion to try other distros in no particular order I tried Ubuntu, Mint, Manjaro, and Netrunner.  All of these had the same issue I have been experiencing and all showed the same error message at boot that I was seeing in P8r.
The last distro I tried and I'm currently trying to iron out on this new Coffee Lake build is Debian 9.3-xface. It seems to work just fine. It throws the errors at startup but boots right to the desktop from a stone cold start. Why it is working I don't have a clue. The only thing I observed is the kernel is 4.09 vs. 4.13 and there is no quiet splash. I think it takes longer to boot. Probably because there is so many crap applications I don't need. I really don't like it as much as Peppermint. I have had to work much harder to get things set up. Like wifi, bluetooth,and the printer just to name a few.
I hope that in time I can switch back to Peppermint on this new build. If anyone could venture to guess why this Debian is working while the others do not I would like to know.  Also, I was just wondering if I switch back to kernel 4.09 with Peppermint if that would have worked. Again Just wondering.

I have a Nvidia GTX 750 installed on another machine that I put there for no reason other than I had it. To put it in this SilverStone SUGO Series SG13  on this mitx board may prove to be a task. Things are somewhat cramped in there. I think it would fit but it may not.
If I except this challenge and all goes well, I assume you would want me to try Peppermint 8 respin again. True?

Okay to remove the HWE and go back to the default 16.04 kernel (4.4.0) run these commands in sequence:
(these commands are rather long so will scroll off the page to the right .. be sure to get the entire command .. also DO NOT reboot until told to do so)
Code: [Select]
sudo apt-get install linux-generic linux-signed-generic xserver-xorg xserver-xorg-core xserver-xorg-legacy xserver-xorg-video-all xserver-xorg-video-intel xserver-xorg-video-qxl xserver-xorg-input-all libgl1-mesa-dri:i386 libgl1-mesa-glx:i386then if that command finishes without error:
Code: [Select]
sudo apt-get remove --purge linux-headers-4.13.0-32 linux-headers-4.13.0-32-generic linux-image-4.13.0-32-generic linux-image-extra-4.13.0-32-generic linux-signed-generic-hwe-16.04 linux-signed-image-4.13.0-32-generic linux-signed-image-generic-hwe-16.04if those two commands ran without error .. REBOOT.

Once rebooted, check you're running the 4.4.0 kernel with:
Code: [Select]
uname -aIf you are, go to:-

Menu > System Tools > Synaptic Package Manager

In Synaptic, on the left hand column select the "Status" button .. select the "Not Installed (residual config)" category .. then mark all displayed packages as "Mark for Complete Removal", and click the "Apply" button.

Once those packages are gone, close Synaptic.

Back in the terminal run:
Code: [Select]
sudo apt-get install --reinstall linux-generic linux-signed-generic xserver-xorg xserver-xorg-core xserver-xorg-legacy xserver-xorg-video-all xserver-xorg-video-intel xserver-xorg-video-qxl xserver-xorg-input-all libgl1-mesa-dri:i386 libgl1-mesa-glx:i386this will replace any config files removed previously with the correct ones.

Okay, all done, so test your computer for the issues you've been having.

If you're having no problems, post the output (if any) from:
Code: [Select]
dpkg -l | grep hwe-16.04and
Code: [Select]
dpkg -l | grep 4.13.0so we can see if anything was left behind that shouldn't have been.

Just a reminder, that output is from a clean install with just the usual update upgrade and dist upgrade done once. The earlier modification to the grub has not been done.
Should I put that on this install as it did nothing to help?
Which graphics card do you want me to work with before doing as you requested?
Title: Re: Desktop Issue After Boot

Okay the output shows there's nothing to clean up.

Can you link to whatever showed you this solution? I would love to read more about it.

Sorry but there's no link .. I just noticed that you said the 4.9 kernel worked in Debian, so I wondered if there was some kind of kernel regression in the 4.13 (and possibly later) kernel series, and/or a regression in the later version of the xorg stack which is also updated by hwe-16.04. Now considering the default (non-HWE) kernel for Ubuntu 16.04 (so therefore Peppermint 7 and 8 ) is the 4.4 series, I figured lets test that kernel and xorg stack because they'll continue to get security updates automagically.

Basically we undid the changes applied by the "Hardware Enablement" track for 16.04 (hwe-16.04) as used in Peppermint 8 Respin (and Ubuntu 16.04.3, or distros based on it). So you now have Peppermint 8 built on Ubuntu 16.04 instead of 16.04.3

Sadly this "guess" at what might fix the problem doesn't identify what the actual kernel regression is, or what hardware you have that's triggering the regression :( .. but I guess it's better than nothing ?

But with one problem solved another has popped up. This motherboard has wireless built in and it won't connect. Looking in the forum under networking I found this post that looks like what I am experiencing.   https://forum.peppermintos.com/index.php/topic,5980.0.html

The solution though looks like what I removed. The spoiler shows inxi, iwconfig,and nmcli.

Okay now we have a problem.

That network adapter insn't supported until kernel 4.6.

We could easily install that (or the 4.8) kernel but it will NOT get security updates, nor will it be patched against the Meltdown and Spectre vulnerabilities.

So looks like your decision is between an unpatched and static kernel .. or getting a new wireless adapter :(

Just as a matter on interest, can you post the output from:
Code: [Select]
dmesg | grep iwl

dmesg | grep iwl returns nothing.
FYI Debian network work after I added some firmware.  I found this but don't understand where they got the file from. OpenElectric?

The firmware on its own won't help, if it would, that last command I asked you to run would have spit out that the driver couldn't find the firmware. The problem is the kernel doesn't even contain the driver :(

Once again thank you for all you have done. Maybe by the time Peppermint 9 comes out these issues with Coffee Lake and Intels 3168 ac wireless will be addressed. Anyway the ball is in my court.

How would you like me to post the results?  The original post was solved after all. But??? :-\

Just leave the topic open my mate, and let it slide into obscurity .. I'm sure if anyone has the same issue just searching for coffee lake will find it for them .. if not and they post, we'll know the answer now anyway :)

Since this goes way back and I thought I'd share what has happen since then. Because I could not use wifi with the solution I got here I thought I would keep looking for another distro that would work better. To make a long story short I settled on Solus Gnome. I tried the Budgie but just didn't like it. I don't know why but SG just worked. The issues I had just disappeared. Solus isn't bad but it's not Peppermint.
This week I installed Peppermint 9 and so far all those issues discussed priviously have not materialised. I really like Peppermint and I'm very pleased to be back using it on this machine.

Hey, thanks for the update. Have a karma point for remembering this place and returning to Peppermint.  :D

Another update and the last. Earlier, I thought Peppermint 9 solved my original post. As it turned out it did not. When 9 started acting like 8r I was beside myself. What the heck is going on. I have figured out over these past months that booting up on this machine with this hardware setup just doesn't like cool ambient temperatures of around 50 degrees F. (10C.)  I noticed that the issue showed up again during the same months as the original post. So,because rebooting would work every time I thought I would try and delay the boot in the bios leaving the POST screen on for 20 seconds or so. It worked. Default on the POST screen was 1 second. No other computer that I store at that temperature acts like this machine. So all this is hardware related and why it's happening I'll never know.
