I'm totally desperate. I'm trying to install open source video drivers for my R9 270x, but no matter what I do when I run glxinfo | grep OpenGL it shows 

OpenGL vendor string: VMware, Inc.
OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 3.6, 128 bits)
OpenGL version string: 3.0 Mesa 11.0.2
OpenGL shading language version string: 1.30
OpenGL context flags: (none)

I've been googling this problem for about 2 days already, read all posts related. Nothing works, nothing helps.

What I did: added this ppa

ppa:oibaf/graphics-drivers

And this one

ppa:paulo-miguel-dias/mesa

Then 

apt-get update

I looked into xorg.0.log file and found the following:

[    45.977] (EE) Unable to initialize PCS database
[    45.977] (EE)   Missing PCS defaults file /etc/ati/amdpcsdb.default

45.994] (II) AIGLX: Screen 0 is not DRI2 capable
[    45.994] (EE) AIGLX: reverting to software rendering

Still nothing. When I first installed Ubuntu 15.10 I managed to install this driver correctly and was using it till I decided to try Crimson AMD Driver yesterday (what a big mistake). I didn't like Crimson driver, so I completely uninstalled it. So now I have software rendering and not able to play games anymore, no solution from the web works.

  • Hi Sergey - I would remove the Oibaf drivers, I don't think they are helping you. You should use ppa-purge to do this, other methods will work poorly if at all. Then read this answer - I know it says "ATI" drivers, but the same methods remove the AMD drivers. Finally, I would try to re-install the drivers you had before... – Charles Green Dec 03 '15 at 22:33
  • Thank you for your answer! But, I already did everything you suggest and nothing helps – Sergey Maslov Dec 04 '15 at 11:58

I have the same situation on Ubuntu Xenial. For now, there is a bug for kernel 4.2+

You should do :

sudo ppa-purge oibaf/graphics-drivers
sudo ppa-purge paulo-miguel-dias/mesa
reboot

Then, you can either stay with the opensource AMDGPU driver or downgrade your kernel to 4.1.15 and try again.

sudo apt install fglrx
sudo amdconfig --initial
sudo dpkg-reconfigure xserver-xorg
reboot

To diagnose issue, look at your /var/log/kern or dmesg

grep fglrx /var/log/kern
dmesg | grep fglrx

If you can't reboot, go in recovery mode and work with those command

Good luck :)

  • thank you for your answer. what does this command do? sudo paulo-miguel-dias/mesa. Well, I managed to solve this by reinstalling system and looks like the root of the problem was in remains of official AMD driver, that I uninstalled unproperly. So for this situation the real question is: how to uninstall drivers correctly? – Sergey Maslov Jan 11 '16 at 06:35
