I am running ubuntu 13.04. I tried foolishly to install the legacy ATI drivers on my machine from some repository. I think I managed to remove them but now I am running only on vesa.
Does anyone have an idea how I can change my configuration such that X uses the Gallium driver again?
package list is at http://paste.ubuntu.com/6076883 and Xorg.0.log herehttp://paste.ubuntu.com/6076902
sudo lspci -nnk | grep -A5

Kernel driver in use: wl
Update: Ubuntu starts still into vesa after purging left over fglrx packages on the system and reinstalling the packages suggested. An xorg.conf is not automatically generated also not by a dpkg-reconfigure. I tried a sudo X -configure but the file created does not improve the situation. I can stop the service lightdm, then load the radeon module, start lightdm again and have then the desired result that the Gallium driver is used and working. However, of course that doesn't change the startup behavior. The current Xorg.0.log can be found here http://paste.ubuntu.com/6080770/
cat /proc/cmdline gives:
BOOT_IMAGE=/boot/vmlinuz-3.8.0-30-generic root=UUID=e8b7c26b-537f-486c-b0f5-674f28c5bac0 ro quiet splash

Update: Problem was solved after deleting /etc/modprobe.d/blacklist-fglrx.conf . This file prevented the right driver from getting loaded. Somehow this was not deleted earlier.
