Go to your CONFIG file in /home/user/.quakelive/quakelive/home/baseq3/qzconfig.cfg and add that line:
seta r_enablePostProcess "0"

Do this without the home of QuakeLive opened, because sometimes it can't save the changes, so close QuakeLive, edit that file, open QuakeLive and enjoy!!

It also helped me!! Thank you very much !!
