Description Björn Ruberg 2012-12-28 18:41:39 UTC
Description of problem:
After upgrading to Fedora 18, mesa does not use a hardware accelerated mesa renderer any more, but the llvmpipe renderer which utilises the CPU. 
I first noticed it in chromes about:gpu page - hardware acceleration is not used as it was before.

This problem is not easy to see, as desktop effects will still work as earlier. You have to look into glxinfo to see the problem.

The old hardware is the only laptop I upgraded to Fedora 18 so far.

Version-Release number of selected component (if applicable):
mesa: 9.0.1-1
xorg-x11-drv-intel: 2.16.14

Comment 1 Jean-Philippe GONZALEZ 2012-12-31 11:04:35 UTC
Hello,

Same problem on two intel chipset based laptops recently upgraded to F18 with Fedup :
- intel GM965/GL960
- intel 945GM/GMS/GME, 943/940GML.

This problem is already fixed on testing updates, you only have to :
- enable updates-testing repo (with Yumex by example)
- refresh packages list
- update kernel, mesa and xorg related packages.

After reboot, graphic chipset is correctly detected in gnome shell, driver too (by example Driver : Intel 965GM instead of Gallium 0.4 with LLVM...) and performances are better.

Comment 2 Björn Ruberg 2012-12-31 12:34:24 UTC
Confirmed, the packages from update-testing are better. Leaving this open so others can find the info.
