[ Reason ]
Fix blank screen after GNOME login on some AMD GPUs
[ Impact ]
Some users reported a black screen after logging in to GNOME from GDM
(#1125275, #1125941, #1126174) or a brief flash of a black screen
followed by normal operation (#1125273) after the Debian 13.3 update,
especially if using an AMD GPU and/or an external display. This seems to
have been caused by an upstream change that was only intended for 50.x
but was mistakenly cherry-picked to 49.x and 48.x, and is resolved in
this version by reverting that change.
(Not all configurations with an AMD GPU and an external display had this
problem - I have a system with that setup and it was unaffected.)
[ Tests ]
A functionally equivalent version (differing only in the changelog and
patch header) is available from
<https://people.debian.org/~smcv/temp/2026/bug1125941/revert/>, and the
reporters of #1125275, #1125941 and #1125273 confirmed that it solves
the problem. I've also been using this version on one of my trixie
systems for a while with no problems (although note that I wasn't
affected by the regression).
[ Risks ]
This is a narrowly targeted change that has been through upstream review.
[ Checklist ]
[x] *all* changes are documented in the d/changelog
[x] I reviewed all changes and I approve them
[x] attach debdiff against the package in (old)stable
[x] the issue is verified as fixed in unstable (since 49.3-1)
[ Changes ]
All changes are part of the regression fix.

+ * d/p/Revert-main-Register-session-with-GDM-on-startup.patch:
+ Revert an upstream change that was not intended to be backported
+ to 48.x. A corresponding revert has been queued for inclusion in
+ 48.8 upstream.
+ The change was developed for v50, under the assumption that gdm3
+ changes from v50 would be present, but then mistakenly backported
+ to 48.x and included in the 48.7 release.
+ The resulting change to timings/sequencing triggered regressions in
+ modesetting during first login on some systems, which can result in
+ the Shell UI never appearing.
+ (Closes: #1125941, #1125273, #1125275, #1126174)
