Hi all,
I just updated to buster from stretch (no problems).
I have a desktop with two monitors. I have the basic power saving
setting that blanks the screens after 5 minutes.
When I wake the screens, the primary display is offset to the left by
about 2 inches, leaving a black band along the right hand side of the
monitor.
If I change the resolution of the monitor through the system settings
dialog and then revert to the original the problem is fixed (until the
screens blank again).
I have this issue with Xorg although it was also present with Wayland.
Many apologies for the non-technical nature of this post. Please let me
know what sort of diagnostics would be helpful for identifying the issue.
Take care!
