I'm reinstalling a laptop on Debian, without any surprise I have graphic card issues.
It's a Dell M4700 with a Dell ePort 2 dock station.
I have no issue at all to work with an etxernal monitor using VGA, but once I use one of the DVI/HDMI adapters, black screen.
I'm using buster/testing.
This laptop uses an 'optimus' Nvidia setup:
Code: Select all
$ lspci | grep 'VGA'
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
01:00.0 VGA compatible controller: NVIDIA Corporation GK107GLM [Quadro K2000M] (rev ff)
The xrandr output is still weird:
Code: Select all
$ xrandr --listproviders
Providers: number : 0
Code: Select all
$ xrandr --query
Screen 0: minimum 320 x 200, current 3840 x 1080, maximum 8192 x 8192
XWAYLAND0 connected 1920x1080+1920+0 (normal left inverted right x axis y axis) 340mm x 190mm
1920x1080 59.96*+
XWAYLAND1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 480mm x 270mm
1920x1080 59.96*+
I didn't follow exactly what happened with X11/Wayland, but I'm on wayland now, so this output may be completely normal.
I don't know where I should start, any hints?
