I need a 32-bit Linux for some testing, so I just installed the 32-bit version of Ubuntu MATE 18.04.1 in a KVM virtual machine (with the "Virtual Machine Manager").
I had some weird display problems with the "QXL" virtual graphics card, so I chose "Cirrus" instead and installed from scratch. I chose a standard desktop installation with no updates during installtion. Everything went well, but when the virtual OS booted, there was no menu bars at the top or at the bottom.
Is this a known problem? What can I do to troubleshoot this issue?
In the meantime, I'll update the virtual system, to see if that helps.
