I use the nvidia-dkms package on the host (Arch).
But now I’m confused. You asked about the output of pacman -Qm and lspci -vnn on the host (Arch) not the guest (Antergos), or not?
The host (Arch) although it has so many AUR packages runs without any issues. The guest (Antergos) has far less packages.
$ aurman -Q | grep virtualbox virtualbox 6.0.2-1 virtualbox-ext-oracle 6.0.2-1 virtualbox-host-dkms 6.0.2-1
$ groups myuser wheel users vboxusers myuser
$ aurman -Q | grep virtualbox virtualbox-guest-dkms 6.0.2-1 virtualbox-guest-utils 6.0.2-1
$ groups myuser wheel vboxsf myuser
The freeze occurred here:
Jan 20 15:05:42 antergos-sd plasmashell: qt.qpa.xcb: QXcbConnection: XCB error: 2 (BadValue), sequence: 13324, resource id: 75497509, major code: 142 (Unknown), minor code: 3
Then I started a tty:
Jan 20 15:08:23 antergos-sd systemd: Started Getty on tty2.
And finally I did a reboot:
Jan 20 15:16:59 antergos-sd systemd-journald: Journal stopped
– Reboot –

qt.qpa.xcb: QXcbConnection: XCB error
appeared already in the morning at 08:42 as I powered on the VM and many times until the VM finally freezed at 15:05.
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.
It happened again.
I have attached the output of
# journalctl -b -0
as well as the output of:
# dmesg | grep fail
There is 1 error in the first one (about XCB error) and 3 errors (about NMI watchdog, acpi and vboxsf) in the second one.
Not sure, but I think the culprit is vboxsf which is related to the Guest Additions. I’ve done some research and I found these tickets on virtualbox.org:
although I don’t use 3D option.
What can I do next?
I shoud have checked if a process is causing the freeze. Actually the last freeze happened after I opened postman. But again not sure if this was really the culprit…
