Description Barry Jackson 2016-05-03 00:35:29 CEST
Description of problem:
When cold booting into plasma (x86_64) sddm (using sddm-kcm and breeze) as described here:
https://bugs.mageia.org/show_bug.cgi?id=18157#c5
the login screen never changes despite the login working in the background and the desktop being rendered correctly (in the background).
CTRL/ALT/F2 then CTRL/ALT/F1 switches to the desktop which then works fine.

A warm boot (restart) works correctly.

This started about 10 days ago, but it is only recently that I realized the relevance of cold/warm boot and the switching to tty2 and back to bring up the correct graphical screen.

Version-Release number of selected component (if applicable):

Can you attach the output of (as root) "journalctl -ab" from when this happens?

journalctl -ab output

I waited about a minute at the hung sddm login screen then hit CTRL/ALT/F2 and CTRL/ALT/F1 before getting this journal output.

Based on the description, this sounds like a video driver issue.  Which one are you using?  I doubt Nicolas is the correct assignee for this issue.

Also happens sometimes on warm reboot - seems fairly random lately, but still happens on about 75% of boots. If I wait a minute and switch ttys back and forth the desktop is fully set up and ready on switch over, so nothing is being delayed by the 'apparent' hang on the login screen.
Comment 9 Barry Jackson 2016-06-08 13:20:46 CEST
If I leave the machine sat displaying the log-in sddm screen (apparently hanging) until the screen blanker kicks in (after 10 mins here), moving the mouse restores the screen to the working desktop.
I monitored both tailf Xorg.0.log and journalctl -f while this happened from another machine over ssh and nothing was added when that happened.

Having had a SSD fail, I have re-installed Mga6 and initially did not install sddm-kcm.

Without sddm-kcm I did not notice this bug, however now I have sddm-kcm installed and am using the breeze login theme, the issue has returned.

Changing summary to reflect this.

Summary: sddm hangs after login (on login screen) after cold boot (not warm) => sddm hangs using sddm-kcm and breeze login theme

Comment 12 Barry Jackson 2016-07-15 00:27:17 CEST
Doing more testing with different SDDM log-in themes, I am only seeing this issue with the Breeze login theme.

If I remove the sddm-kcm package, which ever theme was last used remains active, but then there is no option in systemsettings -> startup/shutdown to change it. 

Even with sddm-kcm installed, (which adds the 'SDDM login' option to the left panel in systemsettings -> startup/shutdown) the original default login theme from a fresh plasma install is not listed, so having once used sddm-kcm to change it, there is no way back. Maybe this needs a separate bug?

I am switching to Maui and will test for a few days to be sure it does not recur.

Maui works fine except for https://bugs.mageia.org/show_bug.cgi?id=19087

Comment 15 Barry Jackson 2017-03-17 20:41:27 CET
No - ssems fixed now  :)
Comment 16 Barry Jackson 2017-03-18 00:53:06 CET
Closing as all is working after recent updates to sddm and maui is no longer shipped with sddm.

Status: REOPENED => RESOLVED
Resolution: (none) => FIXED
