Public bug reported:
After recent upgrade to 5.4.0-73-generic switching to 1920x1080
resolution started to fail with no signal passed to external HDMI TV.
Recognized modes:
DP-2-2 connected 1360x768+0+80 (normal left inverted right x axis y axis) 640mm
x 360mm
1360x768 59.80*+
1920x1080 60.00
1024x768 60.00
800x600 60.32
640x480 59.94
To reproduce:
$ xrandr --verbose --output DP-2-2 --mode 1920x1080
screen 0: 2960x1160 772x302 mm 97.28dpi
crtc 1: 1920x1080 60.00 +0+80 "DP-2-2"
Machine itself:
- Lenovo L440 with docking station
- Philips 32PFL3118T/12 (do support 1920x1080)
Any ideas how to proceed debugging this stuff?
