Bug ID: 483006
Summary: Saving AutoLogin "Session=" key as plasma, should be
plasmax11.desktop
Classification: Applications
Product: systemsettings
Version: 6.0.1
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: kcm_sddm
Assignee: plasma-b...@kde.org
Reporter: dylanmyers...@gmail.com
CC: k...@david-redondo.de, k...@davidedmundson.co.uk
Target Milestone: ---
SUMMARY
My system wouldnt boot into sddm at first, so i booted into a TTY. After some
research and log analysis, SDDM was reading the kde_settings.conf file located
in /etc/sddm.conf.d/ and trying to load that. Since i had autologin selected in
system settings, this section was added to that .conf file. However, it is
written Session=plasma, which i guess SDDM may have had a recent update that
requires the .desktop extension in .conf files. After changing this to
'Session=plasmax11.desktop' my system booted normally.
Referring back to the logs from journalctl, i noticed that after reading that
file, even though I had DisplayServer=x11 automatically generated in SDDM
system .conf file, since it was not specified in kde_settings.conf, for error
handling SDDM tried to instead start a Wayland session, which i do not have
properly configured on my system, thus resulting in kwin-wayland pageflip
time-outs as well as nvidia-drm time-outs.
STEPS TO REPRODUCE
1. Make sure Wayland is not properly configured
2. Make sure it is indeed set 'Session=plasma' in
/etc/sddm.conf.d/kde_settings.conf AFTER enabling autologin in system settings.
If it is instead Session=plasmax11.desktop, then this bug report is null, and
there may be a different cause or service dynamically changing it on my system,
or possibly not caching it properly.
3. Reboot the system normally. It should fail and try to start a wayland
session.
OBSERVED RESULT
Failure to show splash screen and the rest of kde
EXPECTED RESULT
When applying settings related to sddm, lde_settings.conf should be dynamically
edited with valid values.
