First, some context. Recently I've had issues with Plasma (maybe nVidia
related), like desktop freeze, or just applets, graphics acceleration glitches
(like drawing sort of back and forth "in time", i.e. redrawing frames from the
past second, then going further and so on), hidden panels being paint on top of
everything, although they were hidden.
I've read Wayland works better than X11, as I currently use, so I've logged off
and logged in to a Wayland session.
Wayland seems to draw better nowadays, but can't use it because of mouse
problems, it becomes slow and jumpy, actually unusable. So I've switched back
to X11 by loggin off/loggin on to X1 session.
I have several apps that I left open to be restored, mainly Dolphin instances
for my current activities.
After loggin in back to X11, those Dolphin instances were missing. I have spent
few minutes (again) to fake the session in ~/.config/ksmserverrc file, but it's
pretty tedious. On one hand, I've found many old dolphin session related files
in ~/.config/session, none related to the latest session, which is unexpected.
Why having those (orphan?) session files, but none related to my targeted
session. They were there in the past, but not this time, usually removed from
the ~/.config/ksmserverrc file only.
STEPS TO REPRODUCE
1. Open few Dolphin instances.
2. Log off without closing Dolphin instances.
3. Log in as different server session, X11 -> Wayland, then Wayland -> X11.
4. Dolphin is not restored.
OBSERVED RESULT
Dolphin is not restored.
EXPECTED RESULT
Dolphin instances and other (suitable to session restore) apps are restored.
