Changed DE - Can no longer launch File Manager

Post by Akovia »

Hi,
Just switched from XFCE to KDE-Plasma. After switching I've updated the mime db to reflect dolphin as the file manager, and it does seem to try to open it, but fails with these errors. (The dolphin icon bounces then stops)

Code: Select all

 ** start condition wait
qt5ct: using qt5ct plugin
kf.windowsystem: Could not find any platform plugin
/usr/bin/dolphin: symbol lookup error: /usr/lib/libQt5WaylandClient.so.5: undefined symbol: _ZTI27QPlatformServiceColorPicker, version Qt_5_PRIVATE_AP
I removed and and did a fresh build/install through the aur. I also tried reinstalling qt5ct because I was getting an error without it.

Code: Select all

Arch Linux
KDE Plasma Version: 5.26.5
KDE Frameworks Version: 5.101.0
Qt Version: 5.15.8
Kernel Version: 6.1.6-arch1-1 (64-bit)
Graphics Platform: X11
Processors: 8 × Intel® Core™ i7-9700K CPU @ 3.60GHz
Memory: 62.7 GiB of RAM
Graphics Processor: NVIDIA GeForce RTX 2070 SUPER/PCIe/SSE2
Thanks!

Sorry I haven't had time to do this earlier.

Could you please be more specific on what you need me to do? The only reference I could find was here, and following their instruction to set the variable to a "non-zero" value did nothing.

Code: Select all

$ QT_DEBUG_PLUGINS=1
$ echo $QT_DEBUG_PLUGINS
1
The error is the same as before, if it's even related..

Code: Select all

/usr/bin/dolphin: symbol lookup error: /usr/lib/libQt5WaylandClient.so.5: undefined symbol: _ZTI27QPlatformServiceColorPicker, version Qt_5_PRIVATE_AP
Thanks

Neither, I used the Arch aur package.

That's odd. Arch is a rolling release and is considered bleeding edge. I can't imagine many releases have a more current version than Arch.

According to their software page for qt, there are only 2 packages at the .12 level.
https://archlinux.org/groups/x86_64/qt/

So I suppose I used the debugging variable properly then? If so, I guess I'll have to wait until Arch releases 5.15.12 to troubleshoot further?
