I’ll poke around there and see if anything shakes loose. Thanks.
I can also say that this trouble has also appeared on my Xfce VM, but in this case I had not as many changes before it showed up. What I did was try (unsuccessfully) to install the VirtualBox Guest Additions, which only had version 6.0.0 installed rather than the one matching my VirtualBox version. This didn’t take because I hadn’t known to update my kernel headers first. I eventually did that and got it going successfully, but the dialog persists.
Ok then I also know. I get the plasma dialog now instead of the one above.
It has to do with automatic screen resolution resizing of VM. When you log into a wayland session with plasma it won’t resize automatically and therefore no notification.
The notification doesn’t bother me and will get sorted out eventually.
OK, just applied the same fix to the KDE VM, and it’s the same message. It was a general problem with Xmessage not having a ~/.Xresources file for configuration and defaulting to a different language untouched by locale.conf. In this instance, it was created with the following contents to render the dialog in English:
This concludes the OS portion of the problem, so I’ll close this and look for VirtualBox answers elsewhere. Thanks, all.
@suedunham One thing I noticed comparing with an Arch install where I don’t get the notify-send is that .vboxclient-display-svga-x11.pid in the user dir is not generated during X11 login on Manjaro.
Executing the following in VM guest brings up the notify-send:
Changing the graphics controller in VM settings to VBoxSVGA seems to overcome the error. Arch also is fine with VMSVGA.
