The llvmpipe CPU gallium driver nowadays supports OpenGL quite well, although it seems it's not yet correct enough for Unity. VMWare is mentioned as the vendor since they've (probably) done most of the llvmpipe driver work, so they get the credit.
The key problem is that fglrx driver was in use, and radeon driver was tried to be temporarily used instead. Removing the fglrx driver has a long history of not working too well - I'm not sure about the current situation - and at least it needs to be completely removed/purged before trying out radeon driver, because of the diversions it makes to move normal Mesa OpenGL libraries away from usage. So, two issues: 1. llvmpipe should be probably blacklisted for Unity for 12.04, forcing to Unity 2D. Even if it would work, it'd mean something's wrong for ati/nvidia/intel users that should use GPU ccelerated drivers. 2. fglrx may need some fixing, although in this specific case some additional questions need to be answered: a) was fglrx removed using Jockey or by manually removing the package (just to collect data, there is no valid reason why both shouldn't work, but with the manual method purge must be used), b) was the computer rebooted in between (both "NonfreeKernelModules: fglrx" and dmesg indicate the module being loaded, possibly interfering) -- 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/956208 Title: Screen corruption on AMD with Radeon driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/956208/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
