I'm a new Arch user, and after initial installation of plasma-desktop and sddm, I'm unable to get past the login screen with Arch Linux installed as a guest VM in VirtualBox. The screen is all black and unresponsive. This symptom is true with either Wayland or X11.
However, I'm able to fix this issue with either of the following:
Enable 3D Acceleration in Display Settings for the VM
-- or --
Select VBoxSVGA as the Graphics Controller in Display Settings for the VM
I found the following bug report at https://bugs.kde.org/ where it highlights this specific problem.
After plasma6 update, VirtualBox VM is unusable with 3D acceleration turned off
Nate Graham from KDE has acknowledged this bug and started a conversation at the vbox-dev mailing list. You can read about it at the following link:
I haven't seen anyone else on these forums talk about this issue specifically. Has anyone else had this problem? Are the Arch developers aware of this?
