My video card is Radeon R9 270 Dual-X. I've read a lot about overwhelming performance of OpenSource drivers compared to proprietary ones, so I'd really like to move to OS drivers. However! I did everything as mentioned on the official Ubuntu wiki page concerning AMD video drivers but still, when I run
glxinfo | grep rend
I get
OpenGL renderer string: Gallium 0.4 on llvmpipe
Which means (as I suppose) that I still use software renderer, which is definitely not good for gaming.
What am I doing wrong?
Edit: I fixed this problem by upgrading from 14.04 to 15.04, but this is not a real fix, just some sort of low qualification level workaround. I think, that the root of the problem lies somewhere in an uncorrectly installed drivers, so a possible solution to this is reinstalling Oibaf drivers. To do so run:
sudo apt-get install ppa-purge
sudo ppa-purge ppa:oibaf/graphics-drivers
sudo reboot
sudo add-apt-repository ppa:oibaf/graphics-drivers
sudo apt-get update
sudo apt-get upgrade
sudo reboot
