Xorg server log just after resolution switch
Using latest software ( linux-4.19.0, xf86-video-nouveau-1.0.15, mesa-18.2.3,
libdrm-2.4.96, xorg-server-1.20.3 ). When I try to change screen resolution
using xrandr to anything below native resolution the screen goes blank. To be
exact
issuing xrandr -s 1024x768 causes the flowing:
1) screen turns completely black right away
2) after some time ( no more that 500ms ), the screen changes to black with
backlight on. Looks a lot like no modesetting console without any content
3) this situation persists, indefinitely
What is interesting is that switching to console works. The console just works.
However when I switch back to X, the above procedure repeats with one detail -
for a brief moment ( at the same moment as step 1) ) the content of desktop in
selected resolution is visible. It seems that the desktop content is somewhere
in memory but the driver decides to render some other area of memory
The only resolution to this problem that is working is to use older kernel,
linux-4.9.95 to be precise
I discovered the issue, playing games through wine. But to isolate the cause I
gathered dmesg & xorg.log, running only an openbox and using xrandr to cause
the issue
I don't know what further info could be usefull
