With Catalyst 13.2 beta7 (2:12.100-0ubuntu1) not much has changed (not even the version number!), so to sum it up: -2D and 3D acceleration is mostly fine with both the iGPU and dGPU (at least Unity and some OpenGL appplications such as glxgears work correctly) -XvBA seems to be broken (or the xvba-va-driver package no longer works correctly with the new driver) -when using the iGPU the system crashes in a reproducible manner (this is described in bug #1088220), if the dGPU is needed, then it is probably better to open a terminal after login and to enter
sudo amdconfig --px-dgpu After system restart the dGPU should be in use (and probably the system restart itself will result in a crash, because of the aforementioned bug, however next time Ubuntu is booted, the dGPU should be used). Sometimes restarting the X server by logging out after entering the command is enough to switch. P.S:: @Nick Andrik: I think the last comment of bug #1088220 was wrongly posted there because the same comment is in this bug. Could you please confirm this and eventually add a comment stating that the bug still persists? -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/1068404 Title: Low graphics mode in muxless hybrid ATI/Intel GPU systems after fglrx upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/1068404/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
