Seems like a graphics issue. Wayland or X11? (In reply to Nate Graham from comment #1) > Seems like a graphics issue. Wayland or X11? Thanks for the reply! I am using X11. I have tried adding 90-monitor.conf in /etc/X11/xorg.conf.d: Section "Monitor" Identifier "<default monitor>" DisplaySize 345 194 # in millimeters EndSection But it doesn't work. Thanks for the info. The problem disappears after I switch from HDMI to DisplayPort. Closed. |
