I’m running Antergos with KDE Plasma on a VirtualBox Machine. For a long time now the machine keeps freezing irregularly. I can move the mouse pointer around but I cannot click anything. The upgrade of VirtualBox from v5 to v6 didn’t help.
I cannot tell what causes the freeze. With journalctl I see this error:
qt.qpa.xcb: QXcbConnection: XCB error:
very often but it seems to be common:
and not the culprit.
