Package: gdm3
Version: 43.0-3
Followup-For: Bug #894098
X-Debbugs-Cc: budheal...@gmail.com
Dear Maintainer,
* What led up to the situation?
Fresh install of bookworm weekly build (2023-03-20)
* What exactly did you do (or not do) that was effective (or
ineffective)?
HDMI showed extended desktop in both the login screen and now after logged in.
I will submit a separate bug report for the "Displays" accessory but its
failures could show that gdm3 can lose the frame buffer addresses. If one
changes the external display location, either or both displays may go dark, or
the laptop's display can show enlarged pixels at a translated place with wrong
colors (aha, I remember those fights with the frame buffers, long ago now) and
the external monitor may be dark with only the cursor (mouse pointer) showing
but not the windows being dragged around). We can't have gdm3 thinking it can
scribble at the wrong location.
I did not check DisplayPort and will rummage around for a cable.
* What was the outcome of this action?
When an HDMI-enabled display was plugged, it was shown as directly to the right
of the internal laptop's display. Trying to move the display's location had
unexpected results. The displays may go dark or the internal display may show
artifccts and dragging fails in those cases.
* What outcome did you expect instead?
Allow multiple displays extend the desktop display.
