This bug report has become a real mess with different hardware vendors, different hardware models, and different hardware configurations.
The original reporter has hybrid Intel Sandy Bridge HD3000 graphics and NVIDIA GF108M [GeForce GT 540M] graphics. DRI PRIME support and reverse DRI PRIME support should be working on this hardware configuration and I am not experienced enough to determine why. I suggest filing a bug in the nouveau driver upstream at bugs.freedesktop.org You can than link that bug report to this bug report by clicking on "Also affects project" near the top of this page. Everyone else - please run ubuntu-bug to file a new bug report so that we can get a fresh set of log files and system information. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1268146 Title: Very high cpu usage for compiz in 14.04 (mesa incorrectly using llvmpipe) Status in mesa package in Ubuntu: Confirmed Bug description: I just upgraded to 14.04, and I'm seeing 50%-500% cpu usage from compiz. Strangely, glxinfo reports this, which is totally incorrect - I'm running on Intel Sandy Bridge HD3000 graphics and VMware isn't even installed on this PC: OpenGL vendor string: VMware, Inc. OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 3.4, 256 bits) OpenGL version string: 2.1 Mesa 10.0.1 So I guess that compiz might be using lots of cpu because it's using llvmpipe as the renderer. So is this a mesa bug?
