xorg output w/ segfault & backtrace
Good day,
after updating to latest xf86-video-drivers, X segfaults when attempting to
offload Nvidia-blob->Intel via randr 1.4 (PRIME, optimus).
chipset: sandy bridge + nvidia 540M
arch: linux 3.14.0 (also linux-next)
xf86-video-intel: git
xserver 1.15.0
libdrm: 2.4.52
(x)randr: git
distro: gentoo mixed amd64 multilib
machine: Ideapad Z570
my .xinitrc:
xrandr --setprovideroutputsource "Intel" NVIDIA-0
xrandr --auto
exec awesome
After reverting back 'stable' xf86-video-intel, everything works as expected.
X crashes on second command from .xinitrc (^): xrandr --auto.
When I put "xrandr --listproviders > /home/$USER/xout" in between setprovider
command and auto, output was as expected (listing both nvidia and intel, with
correct capabilities).
If any more information is needed, I'm happy to provide it.
Have a nice day.</pre>
