I added sddm-theme-breeze
and rebooted, yuk! (I had forgotten to perform the sudo update-alternatives --config sddm-ubuntu-theme
step but sddm
had been changed by the additional of a virtual keyboard) making it harder to use.
I’ve seen this before (semi-recently with dual screens) and recalled the on-screen keyboard appearing on secondary display, but it booted with keyboard drawn on black background, on mouse movement etc it would flash between black, on-screen keyboard (using 2/3rds of single display) & background… yuk
If a user watched the display, they’d have trouble being able to login.
sddm
is still working, if I close my eyes & login as I’d expect it to operate, I’m logged in, but visually it’s a mess & unusable on that box.
The behavior is very familiar though, I added kubuntu-desktop
to my Lubuntu focal installs on d755-5 (mentioned 4 messages up, AMD and flashing sddm
; lp 1865837) and that box has only single display and it had the same behavior if I recall correctly. (it was also added to hp8200 install which has the two displays)
Finally I performed the sudo update-alternatives --config sddm-ubuntu-theme
to make the ‘new’ breeze default, and on reboot it hung before eventual shutdown…errors?
sddm
didn’t appear again. The GUI session now has a large pointer, which I can move around with the mouse, but nothing more.
I can fix this currently by changing the theme to something else, but with the virtual keyboard appearing on all themes now, they’re all rather annoying…
I’ve taken some photos of messages I see on screen (sddm-greeter & nouveau) but my phone is being annoying (no messages in dmesg
or journalctl
which I could easily paste; & /var/log/sddm.log
is empty). Most messages appear during shutdown which was ultra slow with breeze the default.
Switching to another theme and shutdown returns to normal, messages gone (just virtual terminal remains which isn’t helpful).
The one message I get on text terminal (with breeze active) is
[ 120.676863] nouveau 0000:01:00.0: DRM: GPU lockup - switching to software fbcon
written after the “Optiplex990 login:”
Either a requirement is missing (package error) or we’re missing something in config??
