All,
You may want to avoid upgrading KDE Plasma to 6.2 in sid. I
upgraded it
earlier and after a reboot I only get a black screen when
logging in.
Whenever someone says, KDE Plasma and black screen together, I
think
"nvidia drivers".
I doubt that is your issue. But do you have an Nvidia GPU in
the computer?
George.
No, I do not have Nvidia. I have Sid in a VM. The black screen is
strange
because I have a visible mouse pointer. I also get crash reporter
popups.
"A black screen with only a visible mouse pointer" is one of the
issues I have seen on computers with an Nvidia GPU, hence to me it was
likely you had an Nvidia GPU, since you do not, then I suspect that
the issue is related to the Graphics type that you have selected for
your VM, maybe changing this to virtio and enabling OpenGL?
FYI: My Debian Testing VM with KDE Plasma Wayland is working well
after updates.
What GPU does your computer have?, and what Graphics system is your
VM using? (Which graphics driver and Display protocol do you use ?)
Were you using a Wayland session or an X11 session?
Do you get to see the SDDM login screen or is that black with a mouse
pointer, too?
I use a Radeon RX 6600 GPU. In Virt-Manager, my Display is Spice
server, Address, Hypervisor default, Port set to Auto. OpenGL is not
selected.
On my Debian Bookworm i7 Intel computer, I had a Debian Testing VM
with Cinnamon, so I cloned this VM, ran updates and then installed
kde-full. During the installation I selected "sddm" for the default
display manager.
When I rebooted I could see the SDDM login screen, and for the
"Session", I selected Plasma (Wayland), then logged in normally.
Everything was working as expected.
If I selected the QXL video type, then when I booted up, the VM hung
during loading and no mouse pointer. When I changed back to the
virtio driver, all worked well and I was able log in and watch youtube
videos.
Please let me know if I can help.
Here are my VM settings for the display
*
----------------------------------
When using Cinnamon I usually enable "OpenGL" too, so I tried this
too.
