Hi!
When 5.4-rc1 is booted on thinkpad X220 I get "snow" and other
artefacts on digital output.
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation
Core Processor Family Integrated Graphics Controller (rev 09)
It already snows when kernel is booting, snow continues in X.
HDMI1 connected primary 1920x1080+0+0 (normal left inverted right x
axis y axis) 478mm x 268mm
1920x1080 60.00*+
Snow continues in other video modes:
pavel@duo:~$ xrandr --output HDMI1 --mode 1024x768
pavel@duo:~$
VGA output appears normal.
Any ideas?
Best regards,
Pavel

Sorry, false alarm. I seem to have a hardware problem, it persisted
reboot to older kernel, and went away after I wiggled cables.
Best regards,
Pavel
