gnome shell slow and reporting Gallium 0.4 on llvmpipe instead of intel
Hi I'm running F22 on a Dell Vostro 3460 with Intel + Nvidia graphics card.
The settings/details report
Processor: Intel® Core™ i7-3612QM CPU @ 2.10GHz × 8
Graphics: Gallium 0.4 on llvmpipe (LLVM 3.5, 256 bits)

however lspci -v yields

so as far as i can tell, the intel driver is used. my questions are:
- Is my interpretation correct that GNOME runs on software rendering? This would be consistent with high CPU load observed and sluggy desktop
- How can I change this?
- Is it okay that the nouveau driver seems to be in use as well? I installed bumblebee with proprietary drivers
Have you enabled bumblebee ?
What are the result of this command :
sudo systemstl status umblebeed?I think your guess is right. I realized that it does not always display the gallium driver but rather the correct "Intel® Ivybridge Mobile" under details. I tried to figure out under what circumstances it changes, but didn't have luck yet. however, I found the following to crash my entire system (not even ctrl-alt-f2 anymore)
optirun glxgearsoptirun glxgearsafter that, I can only pull the plug.
Correction on my comment, it is
sudo systemstl status bumblebeed
