Comment 41 for bug 568988

Yes, mark the xorg-server and set version. One short notice: If you do so, you have to look for new versions manually, i.e. in the ppa. If you take a look at the ppa should get an "new version available" or so. Anyway, if Catalyst run without problems ther is no reason to change sub-minor-versions as 1.7.6-1 -2 -3. It will make no sence, nor in performance nor is stability. Relax and wait for a few days, you will miss nothing.

As i wrote so, i'm use 1.8.0.1 in Arch. Nice to have, but not a must... If the 1.7.6 runs stable, yust be lucky.
