<pre>I am using a Thinkpad W530 which features an Intel GPU (Ivy Bridge) hooked up
to the internal LCD and an Nvidia K2000M (NVE7/GK107) hooked up to the
DisplayPorts.
Gentoo Linux
Kernel: 4.14.65
xorg-server-1.19.5
xf86-video-intel-2.99.917_p20180214
xf86-video-nouveau-1.0.15
Both GPUs drive outputs via "xrandr --setprovideroutputsource nouveau Intel".
Under these conditions, changing monitor layouts works once. Then, when the
laptop is suspended and brought to a different workplace with a different
monitor layout, most subsequent xrandr calls fail. RRSetScreenSize refuses to
work. Example:
xrandr --output LVDS1 --mode 1920x1080 --pos 0x0 --rotate normal
xrandr --output DP-1-2 --primary --mode 2560x1440 --pos 1920x0 --rotate
normal
xrandr --output DP-1-3 --mode 2560x1440 --pos 4480x0 --rotate normal
Result:
X Error of failed request: BadValue (integer parameter out of range for
operation)
Major opcode of failed request: 139 (RANDR)
Minor opcode of failed request: 7 (RRSetScreenSize)
Value in failed request: 0x0
Serial number of failed request: 57
Current serial number in output stream: 58
Once this bug appears, xrandr behaves pretty strangely and "randomly" as far as
requested changes go:
- xrandr refuses to set some modes/positions/rotations
- This can be partially mitigated by toggling outputs off entirely and on
again. xrandr will still complain, but do as told
- Trying many different modes/positions/rotations and off/on cycles may
eventually yield the desired layout
- Attempts to change the screen size directly with e.g. "xrandr --db 9999x9999"
fails with the same error
- Something simple like making an active output primary, e.g. "xrandr --output
DP-1-2 --primary" fails with the same error
- Setting the same layout that is currently active is also complained about
- xrandr calls that previously failed may suddenly work after waiting a few
hours
Neither the kernel nor X show any relevant logs. I will check other debug
levels as instructed.
If you would like me to test anything or need more information, please let me
know.
Thanks!</pre>
