General Discussion / Thoughts on Bitcoin
« on: October 06, 2015, 01:38:40 pm »
I'm curious to hear every(any)ones thoughts on Bitcoin. I am well rooted in the Bitcoin world and always like to hear the opinions of others on the subject.  ;D

Software & Applications / Re: Unexpected apt behaviour [SOLVED]

Proprietary graphics drivers installed from somewhere other than the default repositories may need to be recompiled/reinstalled after a kernel update .. the ones in the repos will (if necessary) usually be updated at the same time as a kernel update is released.

Yup, and I saw this with both the Nvidia drivers (when using the .run file, not on Peppermint 6 but on 5  ;)) and Cuda (again using the .run file). Again, the only reason I was using the .run files instead of the normal repos is because (within the last year) there were numerous compatibility issues with the current drivers and my GPU. In order to display acceptable graphics I had to use the .run file.

What I was saying was, just about every time I updated my kernel it would break the driver. I would then re-install the driver (via .run) and that would break everything (maybe because the .run is installing and older kernel?). All I know is I now tiptoe around every kernel update.

Oh ya, Blender works with both GPUs  :D

I still haven't tested the nvcc compiler, probably do that today.

this does NOT require a dist-upgrade because the package name (linux-image-3.16.0-50-generic) stayed the same, only the version number changed .. so it's an update to a package that ALREADY EXISTS on you system.
(the old version will be REPLACED by the new version, leaving only one set of 3.16.0-50 packages)

apt-get upgrade
CANNOT add new packages to your system, only upgrade ones that already exist

This helps me understand what is happening in my case. I guess something is not being transfered to the new kernel during the upgrade.

Are you talking about the Nvidia .run file? If you use the .run file (which for me was all that I could use until recently for some reason  :-\) you need to do a couple of things before executing the .run file otherwise it will fail. Things like stopping lightdm and logging-in without graphical interface. Quoting from:
Download either 32 bit or 64 bit driver depending on your architecture.

First make sure that remove any previous driver install, using
Code: [Select]
sudo apt-get purge nvidia*
Once you're logged in, Press Ctrl+Alt+F1, to switch to the first virtual terminal and login. Once logged in, navigate to where the file was downloaded, and do the command(s) below:

Code: [Select]
sudo service lightdm stop
chmod +x NVIDIA-Linux-*-352*.run
sudo sh ~/Downloads/NVIDIA-Linux-*-352*.run

You may have to also blacklist nouveau but I think it is done automatically now.

You can check if it is blacklisted by entering:
Code: [Select]
grep 'nouveau' /etc/modprobe.d/* | grep nvidia
you should see something like:

Code: [Select]
/etc/modprobe.d/nvidia-352_hybrid.conf:blacklist nouveau
/etc/modprobe.d/nvidia-352_hybrid.conf:blacklist lbm-nouveau
/etc/modprobe.d/nvidia-352_hybrid.conf:alias nouveau off
/etc/modprobe.d/nvidia-352_hybrid.conf:alias lbm-nouveau off
/etc/modprobe.d/nvidia-graphics-drivers.conf:blacklist nouveau
/etc/modprobe.d/nvidia-graphics-drivers.conf:blacklist lbm-nouveau
/etc/modprobe.d/nvidia-graphics-drivers.conf:alias nouveau off
/etc/modprobe.d/nvidia-graphics-drivers.conf:alias lbm-nouveau off

If you don't see the above you need to create the .conf files with the following lines:
"/etc/modprobe.d/nvidia-352_hybrid.conf" :
Code: [Select]
blacklist nouveau
blacklist lbm-nouveau
alias nouveau off
alias lbm-nouveau off

"/etc/modprobe.d/nvidia-graphics-drivers.conf" :
Code: [Select]
blacklist nouveau
blacklist lbm-nouveau
alias nouveau off
alias lbm-nouveau off

Once done, press Ctrl+Alt+F7 to go back to GUI, and reboot.

eww  :-X

I have wondose installed on my machine but never use it... not even as a backup.  :P

I had downloaded the local .deb (+2Gb file) and the first time it didn't work (maybe it was just me) but it worked this time, and it upgraded my driver to 352.  :)

Everything seemed fine, I had blender using the GPUs, cuda-7.5 installed, and a newer driver (352). Then the dreaded kernel update showed its face. I just told the update manager to ignore it. I am not ready to test a kernel upgrade yet.

I am using 3.16.0-50.66, wants to upgrade to 3.16.0-50.67

Menu -> Preferences ->  Software & Updates

In the "Additional Drivers" what do you have selected? Try switching drivers.

Have you installed a driver yet?

This has been the most straight forward installation of cuda. I was able to add the cuda.deb downloaded from the cuda website using:

Code: [Select]
sudo dpkg -i cuda-repo-*.deb
sudo apt-get update


Code: [Select]
sudo apt-get install cuda
 ??? ::) Why this didn't work before, I have no idea. I had been using the .run file to install cuda because it had been the only download that worked for me. Now the deb works.... :-[

Ill do some testing to make sure it is fine but I think it is now bullet proof. We will see... I will test Blender and the nvcc compiler, see if the libs are in the right spot (this has been an issue with the .run, something about permissions during installation)

I don't  understand why this is not pre- install on  Linux distro.

So you can choose to install it or not  ;) Personally, I would not want this package on my system because I use "dd" (not recommended for new users) for my disk cloning needs.

This is what makes linux so personal to the user using the distro. Unlike windose or app-all, (who don't want you to customize your (technically their) OS to better suit your needs, and increase work flow, but instead want you to fork over your hard earned money to learn their neglected software  ::)

Its your operating system, make it yours  ;)

Why are you running that command ?
Because apt-get (or the package itself) suggested It be done.  ::)
I figure it wont hurt anything (for now) to leave it be, but as stated above, I am trying to make this system as clean as possible. So I would like to iron out the wrinkles before stacking too much on top it.

But like I said, if it is not an issue than so be it. I just have a slight case of OCD and that stuff bothers me :P.

are you still getting the same error from the graphics driver installer ?

Well this time I tried the "Additional drivers" route and... Abracadabra! The driver worked  ::) :-[

The next step is to try and install cuda-7.5 without breaking the driver. Thinking about it, maybe I should just let the cuda installer choose the driver, I think it picks 340 which is lower then what im on now (346) but if it works then Ill be happy. Ill try installing cuda with the 346 driver activated and we will see if it plays nice  ::).

Well... to be honest I deleted the partition so I can't give it a try anymore  :-[ but if it happens again (which in my recent case, it will) I'll have a look at the xorg.conf. It has been a issue before.

I deleted the partition partially out of frustration lol. I couldn't get my Peppermint 6 usb to boot . I had 2 Peppermint 6s installed already on the drive and when I hit F12 and boot from the usb it would go to the normal grub boot screen without an "install peppermint" option. So I got rid of both  peppermint installations and now have one fresh one.

I did a speedy reinstall of peppermint 6 (getting quite proficient at it  :P) and got the same warning when updating  :-[.

Code: [Select]
sudo apt-get install libgdk-pixbuf2.0-0 libgdk-pixbuf2.0-dev

Installed fine.

Tried (again):
Code: [Select]
gdk-pixbuf-query-loaders > /usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders.cache
Which gave me "bash: /usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders.cache: Permission denied"
So I tried:
Code: [Select]
gdk-pixbuf-query-loaders > sudo /usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders.cache
Which I know is wrong  but it at least gave me the following error:

not sure where to go from here :/

So because of my previous troubles:,2550.msg25010.html#msg25010

I will be documenting what I do (step by step), in an attempt to make a stable peppermint os with cuda (7.5) and a feature rich nvidia driver installed and allow everyone to help me along the way (because I need it  ::)).

First I added ppa:xorg-edgers/ppa (which is a recommended ppa for more "up-to-date" nvidia drivers). Really, this could be the reason everything keeps breaking... but... ONWARD!

Code: [Select]
sudo add-apt-repository ppa:xorg-edgers/ppa -y
sudo apt-get update
sudo apt-get upgrade

I see this during the upgrade (and it hangs there for a minute):

So i give what it recommends a try:
Code: [Select]
gdk-pixbuf-query-loaders > /usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders.cache
It gave me issues:

Code: [Select]
sudo apt-get install libgdk-pixbuf2.0-dev

And that is where I gave up... I am about to wipe clean and try again... not sure about these errors, I don't want to start putting packages on top of a potentially broken system if it will just cause problems in the future.  ::)
