Re: [SOLVED] Intel DRI does not work after update

Not sure if it helps, but did you reboot after updating the kernel?

$ pkgfile /usr/lib/xorg/modules/dri/swrast_dri.so
extra/libgl
$ pkgfile /usr/lib/xorg/modules/dri/i965_dri.so
extra/intel-dri

Do you have these packages installed?

Re: [SOLVED] Intel DRI does not work after update

Hi Karol,

1) Of cause I did, several times

2) Both packages are installed

yaourt -Ss libgl | grep installed
extra/libgl 9.0-1 [installed]

yaourt -Ss intel-dri | grep installed
extra/intel-dri 9.0-1 [installed]

Re: [SOLVED] Intel DRI does not work after update

OT: A simpler way to check if some packages are installed:

$ pacman -Q intel-dri libgl foobar
intel-dri 9.0-1
libgl 9.0-1
error: package 'foobar' was not found

What's the output of 'groups'? Maybe you need to add yourself to 'video' group?

Re: [SOLVED] Intel DRI does not work after update

Thank you very much Karol, after:

gpasswd -a [user] video

Everything works:

$ glxinfo | grep renderer
OpenGL renderer string: Mesa DRI Intel(R) Sandybridge Mobile
