Xorg log
I have a laptop with hybrid graphics. When attempting to get xrandr to
identify/use an output attached to the discrete card, Xorg segfaults. Here are
my steps:
startx
xrandr --setprovideroutputsource 1 0
xrandr --auto
After the first `xrandr` call, the external monitor shows up in the output
list. So far so good. As soon as I try to activate it with `xrandr --auto`,
Xorg segfaults. Here's the output of `--listproviders`:
Providers: number : 2
Provider 0: id: 0x8a cap: 0xb, Source Output, Sink Output, Sink Offload
crtcs: 3 outputs: 5 associated providers: 0 name:Intel
Provider 1: id: 0x41 cap: 0xf, Source Output, Sink Output, Source Offload,
Sink Offload crtcs: 1 outputs: 1 associated providers: 0 name:radeon
I will also be attaching my xorg.conf.
I should note that when using "glamor" acceleration for the Radeon device, Xorg
does *not* segfault. However, the resulting output is unusable; I don't know
quite how to describe it beyond saying that the picture on the screen is
jumbled/torn up and illegible. This segfault happens when using "exa" (really
any non-glamor) mode; I have no idea what significance (if any) that might
have.
Please let me know what other information will help.</pre>
