With the 5.19 kernel the HDMI console output uses a larger font. Not all columns and not all lines of the screen buffer are visible. So when reaching the lower end of the HDMI output you start typing in the dark. At least 20 lines of output are invisible. At least 80 columns on the right side are not displayed. This renders the HDMI console unusable. $ cat /sys/class/drm/card0-HDMI-A-1/modes 1024x768 800x600 800x600 848x480 640x480 The 1920x1080 mode is not displayed. The screen is actually running in 1024x768 mode while the screen buffer assumes 1920x1080. With the 5.17 allwinner kernel the problem did not exist.
