Bug ID: 413207
Summary: plasma5 logoff and re-login hangs forever
Product: plasmashell
Version: 5.17.0
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: slartibar...@gmail.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
Hi,
since plasma 5.16.x and 5.17.0 (using zawertun copr repo) on fedora30 i very
often encounter problems when leaving (using logout) and re-login to plasma.
In 5.16.x i could simply try
systemctl restart sddm.service and re-login successfully. Sometimes an
additional 'killall -u <user>' was necessary followed by sddm-restart in a
separate root-vterm.
The sysmptoms are:
sddm accepts your password, then the screen goes black with the rotating
spinner and the kde/plasma logo in the middle.
Normally, the screen flickers once, then the login succeeds and plasma desktop
is available.
When it 'hangs', the flicker is missing and the spinner just goes away, the
logo is also gone, just the mouse cursor remains on a black screen. No desktop
whatsoever, though...
Since 5.17.0, all is way quicker - even the error situation :-))
But, here a new 'quality' occurrs: plasma does not even clear the screen, the
sddm-login with the breeze background picture is still visible, but the
password is greyed out (similar to the 'wrong password' situation, but never
returning nor loading your desktop)
So, here it helps to (using root-vterm) kill the current Xorg process, killall
-u <user>, systemctl restart sddm.service
If you're lucky, then, after a new login-try, your desktop appears again.
Sometimes though, not immediately, it takes way more time for plasma to 'think
this over' and give you access to your desktop...
i didn't find anything particularly interesting in dmesg/xorg.log, maybe other
logs are giving better info?
Any help is appreciated
