With both older manjaro xfce machines (acer acer aspire 7738G AND lenovo thinkpad X240):
Running updates in xfce-pamac, repeatingly the window disappears. Restarting pamac shows, “waiting for annother packetmamanager to finish” for a while. Thereafter, updates are displayed done.
Once I killed pamac, thinking it got totally stuck, which meant to reinstall the whole system.
Any idea, why pacman-windows vanishes while still working?
Second phenomenon, xfce sometimes freezes when moving cursor across the pamac-window. Same when trying to install “ausweis2app” from AUR. Have to restart system.
Possibly because some graphical components has been updated - forcing a window manager restart.
The recommendation is to switch to a TTY and do the system sync there as doing this will ensure the sync process is not interrupted by a window manager reset.
Only Pamac or any GTK4 application? I had problems with GTK4 programs, especially because of the Renderer, which also crashed Pamac.
I used this:
GSK_RENDERER=gl pamac-manager
I put this variable into /etc/environment.
But gl is now unfortunately obsolete and will be replaced by ngl. If nothing is specified, then vulkan is used if possible, which is not fully supported on some Intel GPUs, or not at all, which then leads to crashes.
That should display all possibles values:
GSK_RENDERER=help zenity --info
You can also test whether the older version pamac-gtk3 works better.
