Bug ID: 500495
Summary: Applying screen layout (desktop configuration) and
desktop backgrounds to the login screen (SDDM) does
not take effect
Classification: Plasma
Product: plasmashell
Version: 6.3.0
Platform: Neon
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Session Management
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Target Milestone: 1.0
SUMMARY
I am logged in as a user with membership of the sudo and admin groups
My machine has 3 monitors in a "PLP (portrait-landscape-portrait)
configuration, so screen config is important for the machine to be usable
However changes to the SDDM desktop config and style do not "stick". After
logout the login display uses the default background wallpaper and screen
config, leaving 2 out of 3 monitors with displays rotated by 90 degrees
STEPS TO REPRODUCE
1. Set a custom Display Configuration and "Desktop and Wallpaper"
2. Open the "Login Screen (SDDM)" system setting
3. Select "Apply Plasma Settings"
OBSERVED RESULT
One of the default desktop themes, with no customisation of the screen config
(i.e. screen position and rotation) is applied
EXPECTED RESULT
On this config page, there are selection icons for a couple of default
configurations (Breeze and Maya), plus an "Apply" button at the bottom of the
page.
I would expect selecting one of the default themes and hitting "Apply" would
set SDDM to use that theme. The fact tat the default themes don't handle things
liek screen rotation is annoying, but not surprising.
However, given that the "Apply" button exists to apply a selected theme, my
expectation was that the "Apply Plasma Settings" button was clearly there for a
different purpose, otherwise it would be redundant.
What I expected it to do was apply MY CURRENT PLASMA SETTINGS (theme colours,
wallpapers, AND screen configuration) to SDDM, so that having spent the time to
set up a "sane" desktop config on my account, I could easily apply it the login
environment.
(Note, if the user needs to authenticate as sudo to alter the config of SDDM,
there should be a popup asking for authentication like other admin changes)
