Hello,

I'm running a lot of live ebuilds on one of my systems, to test out the latest git code. This regards mostly Qt5.5.9999, kde-frameworks, kde-plasma, kde-apps, mesa, xf86-video-intel, libdrm, cairo. I'm also using systemd and kdbus. Various issues come up after emerging newer revisions of live packages, but are usually resolved within hours or days. This time however, I hit an issue which not only has not been resolved, but I have been unable to locate any related bug reports in any trackers.

This manifests on both a system with an intel graphics card and on a system with a radeon (r600) graphics card. The radeon system doesn't use live ebuilds for Qt, so I don't think Qt-5.5.9999 is to blame. Neither is xf86-video-*, apparently.

What happens is that sddm, and also the desktop after I login, are black. Some elements are discernible in very dark grey. In sddm, the icons representing the users have gray outlines as well. Hitting Alt-F2 also opens a black rectangle for the app launcher. The widgets work, but everything is black (except for text which is light gray).

I have been digging in the logs for anything suspicious, and the following entry has been coming up roughly since the issue started manifested:

Code:
sddm-greeter[1862]: QSGTextureAtlas: texture atlas allocation failed, code=502


It seems to me that this is the most applicable log entry candidate relating to this issue. Before flooding this thread with log files, does anyone else here have this problem? If yes, is this line present in log files?

And of course, does anyone have any idea which package is causing this issue?

Thanks,
George

Never mind, after 10 days of daily builds, I ran smart-live-rebuild earlier today and the issue's gone... :-)

Such is the nature of live packages...

Yeah, I get that a lot...

However, I wasn't looking for advice on how to avoid such situations in general, I was more interested in figuring out where I should file a bug in this particular instance :-D

It wasn't advice, just a comment. ;)

If you also happen to run live mesa, that might have been the problem (see also broken 11.0.2 release bugs)
