Title: Can't log out. Screens not visible.
Post by: Darciar on August 23, 2016, 11:42:39 pm
Everything seems to be working perfectly in Peppermint, except when I press the menu's logout button. lxsession-logout is listed in the bar at the bottom of the screen, but it is not visible on the desk top so I can't interact with it. If I alt tab through the menus, lxsession-logout is visible but it is greyed out. This was tolerable before, but now the Private Internet Access setting screen is behaving the same way, whereas the day before it worked just fine. Any suggestions as to how I can fix this?

The command for the logout button should be
Code: [Select]
peppermint-logoutnot
Code: [Select]
lxsession-logout
did you keep a home partition from another distro ?

Does running
Code: [Select]
peppermint-logoutbring up the logout screen ?

Thanks for your help!

Yes, the command for the logout button is peppermint-logout

No home partition from another distro. It's a fresh install with the SSD all to itself.

I typed peppermint-logout in the terminal and got this:

Quote
quit

Launching quit manager


 I get the same behavior with the hidden menu as before.

Is your system fully updated ?

can you post the output from
Code: [Select]
dpkg -l | grep lxsession-logoutand
Code: [Select]
ps aux | grep lxsession-logout
Have you tried reinstalling lxsession-logout
Code: [Select]
sudo apt-get install --reinstall lxsession-logout

Rebooted and no change.


BTW I tried Add New Items to the task bar and chose the Action Buttons.

When I attempt to use it, Suspend and Shut Down are greyed out. If I choose Log Out... an Error box appears:

Quote
Failed to run Log Out...

The name org.xfce.SessionManager was not provided by any .service files

Don't know if that helps any.

Post by: PCNetSpec on August 24, 2016, 09:13:55 am
Action buttons is broken in Peppermint as they require the xfce session manager and we use lxsession.

Anyway .. as a matter of interest (and as you seem to have nvidia-prime installed, can you switch to say nouveau and see if that makes a difference .. just as a temporary diagnostic measure.

I go to Peppermint Settings Panel | Software &  Updates | Additional Drivers

and the follwing was already selected:

Using X.Org X server -- Nouveau display driver from xserver-xorg-video-nouveau

I've switched back and forth between the two before to see if there is any difference but didn't notice anything different. Will try again now.


Under the NVIDIA setting there is another. It says

Unknown: Unknown
This device is not working.

Using Processor microcode firmware for Intel CPUs from intel-microcode (proprietary)
Do not use the device.

Tried various combinations of that but not change in behavior.

Hi Darciar

On my Asus MB I set my UEFI to "Other OS's" - windows don't care less if you are dual booting.

Might be worth a tweak - you can always put it back.    With that set, that is when I then install Nvidia Drivers

and have you tried installing the 367.44 proprietary driver directly from the nvidia website
http://www.nvidia.com/download/driverResults.aspx/106780/en-us (http://www.nvidia.com/download/driverResults.aspx/106780/en-us)

361.42 is the one Peppermint offers.

I haven't tried the one from NVIDIA yet.

If switching to the nvidia (361.42) driver didn't help, I doubt if the 367.44 one will

does it eventually work if you keep trying .. as in this bug report ?
https://bugs.launchpad.net/ubuntu/+source/lxsession/+bug/1534798

and does

lxsession-logout(as opposed to peppermint-logout) work ?

As temporary solution I run lxsession-logout in terminal emulator for immediatly terminate program with Ctrl+C, when it didn't appear, and try again. After several repeats it appears on the screen.

Is this a new problem or has it always happened ?

does it work from a LiveUSB session ?

Post by: Darciar on August 24, 2016, 11:30:54 am
I installed Peppermint 7 for the first time yesterday and its always happened.

Same behavior in the LiveUSB. I used Rufus to make it.

Interesting thing  is the PIA program worked properly for a while, then it caught whatever lxsession-logout has.

Hi Darclar
You may need to try and install it again now that you have different UEFI settings. Assuming you kept them.
It's at least worth looking at the Live USB again

Thanks Zeb, I was thinking that too. However I tried the Live USB before my last post and got the same behavior. Anyhoo, I will try another reinstall if nothing else works out.

Hi Darclar
You may need to try and install it again now that you have different UEFI settings.

Don't know if it will make any difference, but ...

When I first installed Peppermint 7 in UEFI/Secure Boot mode, everything worked.

But, as soon as I started haxoring it, adding Conky 1.10.x with all the various depends, et cetera, Secure Boot started causing probs.  I disabled Secure Boot and Legacy ROM in BIOS, e.g. all I'm running now is UEFI mode.

Everything (Peppermint 7, Ubu 16.10, winders 10) is working fine.

If it was me, I'd do a fresh Torrent download, too.

Maybe your iso is corrupt.

I followed the instructions on Checking the Integrity of the Image, so the iso is definitely good.

Interesting thing  is the PIA program worked properly for a while, then it caught whatever lxsession-logout has.

PIA ?

Can you test a Lubuntu 16.04 LiveUSB and see if that does it too ?

Tried it on the live USB release candidate you posted.
All commands worked except for the killall mintUpdate. It said it wasn't running.

When peppermint-logout was called the bug was still there.

Post by: PCNetSpec on August 26, 2016, 05:30:58 am
Well I'm baffled because those are really the  differences (besides the panel) between what we're running and what Lubuntu are running :-\

does it display if you first exit the panel ?

Open a terminal and run:
Code: [Select]
sudo killall xfce4-panelthen does
Code: [Select]
peppermint-logoutwork ?

If necessary you can restart the panel with
Code: [Select]
nohup xfce4-panelthen closing the the terminal with the close button.

[EDIT]

If that doesn't make a difference I guess we could try a different kernel .. but only from an installed version of Peppermint ?
Title: Re: Can't log out. Screens not visible.
Post by: Darciar on August 26, 2016, 10:27:37 am
I ran those commands on my installed version, as well as the RC version you gave me that I put on a live USB and the bug is still there for both.

"If that doesn't make a difference I guess we could try a different kernel .. but only from an installed version of Peppermint ?"

Sure. If you want to put something together I will test it.

Okey dokey, let's try the 4.7.2 kernel.....

It would be STRONGLY advisable to switch back to the open source nouveau driver and reboot BEFORE doing this

Open a terminal and run these commands in sequence:
Code: [Select]
mkdir ~/Desktop/kernel-4.7.2then
Code: [Select]
cd ~/Desktop/kernel-4.7.2then
Code: [Select]
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7.2/linux-headers-4.7.2-040702-generic_4.7.2-040702.201608201334_amd64.debthen
Code: [Select]
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.7.2/linux-headers-4.7.2-040702_4.7.2-040702.201608201334_all.debthen

Code: [Select]
sudo dpkg -i *.debthen REBOOT

Once rebooted, check which kernel you're using with
Code: [Select]
uname -a

Gahhh... I was trying to get my fans working in Linux but failed, so I set my BIOS to its defaults hoping that might do it and now its gone back to "FAILED: nouveau"
I also tried changing UEFI to Other OS. That didn't work, so I disabled UEFI and I still get "FAILED: nouveau".


Should I try the steps you posted just above anyway?

I just tried adding an HDMI TV to my laptop, when I unplugged the TV I had the same problem on the laptop (no logout screen, but displaying on the taskbar) until I rebooted .. are you using multiple monitors ?

Or have you ever had multiple monitors attached ?
Title: Re: Can't log out. Screens not visible.
Post by: Darciar on August 28, 2016, 09:22:32 am
I have a HDMI TV that is plugged into my computer. I only use it to watch movies, so the TV is plugged in but off most of the time.

Well there is the bug! I turned on my TV and the logout panel is appearing on it and I can press the buttons on it if I move the mouse across to the second screen. However it does not show up on my computer monitor, if I click on the second desk top. I have only 2 desk tops.

I ran your latest tests from a liveUSB, as I wanted to see if the problem exists in a non-Ubuntu and it does. I installed Manjaro and whenever you start it up, the login screen appears on my HDMI TV instead of my monitor, despite my telling it the monitor is the primary. I think they programmed it making the assumption that all monitors are next to each other and always on.

Now to the results using Peppermint RC with liveUSB. If you think this is no use, I'll do a full install and try again:

Code: [Select]
lxsession-logout --display=$DISPLAY

lxsession-logout --display=:0.0

The above two same as before. The pannel appears in my HDMI, not in my monitor.

Hi Darclar

I have tried to keep up with what PCNetSPec is asking you to try but he usually leaves me scratching my head more often than not - it amazes me he knows so much.

Simple Q's.   
1.     What monitor is the panel displayed on?  DV-I-1 or HDMI-1
2.    With both monitors attached and switched on - if you use ctrl+alt+del to bring up the logout panel, which monitor does it appear on?

Mine will depend on which monitor I used last (ie I click left monitor and it appears on the left.  I click right monitor and it appears on the right.)

However, using the menu and clicking logout it will always appear on the monitor that has the panel displayed.   Regardless if it is labelled default or not.

Does this help you track down the problem ?   My system is similar to yours, except I use a display port and hdmi and both my monitors are always on with my main large screen having the panel on it.  So for me the logout screen always appears on my main monitor.   but I can make it appear on the hdmi monitor by simply placing the panel on that monitor.

I hope this helps somewhat and doesn't end up confusing the issue even more.
Keep trying, It really is worth it when you get up and running.

Regards Zeb...

I had the same problem, I dunno if it's Peppermint 8's new function, but restoring the desktop theme was an instant success.
