Integrated graphics acceleration not working after uninstalling Bumblebee
Hi :)
I was successfully using Fedora 22 on an Optimus laptop with Bumblebee/proprietary drivers set up as described in the wiki : https://fedoraproject.org/wiki/Bumble...
Everything was working fine until I did a regular system upgrade, which broke Bumblebee. I know Optimus support on linux is experimental so I can live without my nvidia GPU, and I can turn it off in the BIOS. So I uninstalled Bumblebee packages and turned my GPU off but I think I lost my integrated intel graphics chipset. Everything seems to be done on the CPU and it's very slow (web-browsing, even launching emacs is slower) !
I tried to remove/re-install xorg-x11-server-Xorg and xorg-x11-drv-intel and the kernel but it did not work.
Any idea ? Thanks.
Try seeing if you have a left over /etc/X11/xorg.conf. Make a backup of the file, delete it, then reboot. Also check the output of
glxinfo | grep direct
andglxinfo | grep -i opengl
. This will let us see if you have direct rendering or not.
