I have a problem with virtualbox (6.1.16 r140961) when running with KDE. The dialog boxes are not working, not responding when selecting f.e. another VDI disk within a VM configuration. Even the main “preference” configuration of Virtualbox itself is not responding. When configuring only with command line everything is working fine.
Since the application is rendered by GTK i presumed a problem corresponding the rights of my user or the one of the application. I set up another user and gave it a the XFCE desktop which lead to success.
Does anybody have the same problem and already found the solution?
Thank you very much in advance.
Operating System: Manjaro Linux
KDE Plasma Version: 5.20.4
KDE Frameworks Version: 5.76.0
Qt Version: 5.15.2
Kernel Version: 5.9.11-3-MANJARO
OS Type: 64-bit
Processors: 12 × Intel® Core™ i7-8750H CPU @ 2.20GHz
Memory: 31.2 GiB of RAM
Graphics Processor: Mesa Intel® UHD Graphics 630
Virtualbox is a Qt application and uses the native file dialog in KDE Plasma by default.
Did you installed xdg-desktop-portal-gtk over the xdg-desktop-portal-kde ?
Yes. I read that Manjaro is not very happy if you do so, but I thought I give it a try and it worked. I can always rollback. I had the same problem with an other application, but unfortunately I don’t remember which one.
Hello I got the same problem. Uninstalled xdg-desktop-portal-kde and installed gtk one but I still have the same issue. Any chance did I misunderstand what to do to solve it ?
Sorry guys, was busy with celebrating the New Year. I wish you all the very best, be happy and healthy and always find a solution with IT problems.
It is not about the desktops. It is about KDE that has a problem with programs like virtualbox. When virtualbox runs with XDG but doesn’t run with KDE on the same linux kernel, then you can definitely blame KDE for being the sinner.
So in my opinion the discussion about desktops is leading in the wrong direction and since I think KDE is the best desktop I have ever seen I would like to pursue the problem solution as mentioned in my first post.
Update:
I can no longer reproduce the success of running virtualbox with XDG desktop. Both desktops do not work anymore.
Having the same issue here on a freshly installed manjaro. Virtualbox is completely unusable and it is sad to hear that other gtk programs have similar issues. Is there a list of the affected programs?
@bithki dismissing the issue as a KDE problem appears weird. Virtualbox is happy on other KDE distros like kubuntu.
EDIT: this seems to depend on how recent your KDE is (kubuntu ships an older one).
