I recently bought this computer from a used equipment auction. I installed Xubuntu [Ubuntu 14.04 LTS (32 bit)] and decided to try if I can play CounterStrike:Source using Steam here. After installation, I got this message:
I tried a few remedies advised on-line, like
sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update
sudo apt-get dist-upgrade
and
sudo apt-get install xorg-x11-drv-catalyst-devel.i686 xorg-x11-drv-catalyst-libs.i686
but got no results.
