Unable to successfully start XFCE

[bgatessucks]

The desktop starts ($ startxfce4) with a popup window Error: XFCE PolicyKit Agent; after closing it the menus are responsive and I can start applications, for instance a terminal. However the keyboard does not work: I cannot type in a terminal (but I can paste with the mouse right button).

Which X server are you using?

[bgatessucks]

As said above, VcXsvr X Server version 1.20.1.4 from sourceforge.

I've been running with no (significant) problems using the X410 display window. Here's a log of the startxfce4 console output.

Of possible interest, I installed the KDE Desktop group, but plasmashell won't start, However the striping of the ABI section from libQt5Core.so (suggested in the Ubuntu blog) allows (the ones I use) of the KDE Qt5 applications to run in the Xfce desktop.

startxfce4.log

[WSLUser]

xfce4-session always works even if startxfce4 doesn't. There is known issue with KDE on WSL. There's an issue tracker for it (both WSL under GUI issue and under Pengwin) that has some solutions that may be able to be applied to Fedora (haven't had a chance to test) but one of those required options is the removal of the libQt5Core.so.

[bgatessucks]

The suggestion here works and it solves my problem. I can start and use XFCE.
