Public bug reported:
After upgrading to 11.10 I am getting terrible screen flicker with the
opensourced ATI drivers. Every time I go to the desktop switcher I get
crazy flickering across the screen. When I go into my lenses I get
horrible flickering.
I tried installing gnome-shell to see if there would be flickering
there, and I still get occasional flickering, but not nearly as much. I
even tried install Kubuntu, but it is also suffering from horrible
flickering.
I believe the problem has to do with xorg, during the early parts in
alpha development I didn't have a flickering problem, but towards the
end and now it is extremely bad.
Also, when I install the fglrx proprietary drivers the flickering goes
away (though the window responsibleness is horrible). Also, I am still
having the issue when uninstalling fglrx it breaks my entire desktop.
I am running Ubuntu 11.10 x64, on an acer aspire 5553 with a Mobility
Radeon HD 4200 series card.
Will we be seeing Catalyst 11.9 or 11.10 at all?
