Thank you for taking the time to report this bug and helping to make
Ubuntu better. It sounds like some part of the system has crashed. To
help us find the cause of the crash please follow these steps:
1. Look in /var/crash for crash files and if found run:
ubuntu-bug YOURFILE.crash
Then tell us the ID of the newly-created bug.
2. If step 1 failed then look at https://errors.ubuntu.com/user/ID where
ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine.
Do you find any links to recent problems on that page? If so then please
send the links to us.
3. If step 2 also failed then apply the workaround from bug 994921,
reboot, reproduce the crash, and retry step 1.
Please take care to avoid attaching .crash files to bugs as we are
unable to process them as file attachments. It would also be a security
risk for yourself.

Title:
Fractional scaling crashes X11 session in KVM based virtual machines
Status in gnome-shell package in Ubuntu:
Incomplete
Bug description:
In focal release of Ubuntu proper (GNOME Desktop) i was going trought the
release on livestream using KVM based VM(libvirtd and virt-manager using
default video settings provided by virt-manager, Host is ubuntu mate 20.04) and
one of the things i was trying to show was fractional scaling which made my X11
session unusable. Screen turned black. Tryed different settings in Virt-manager
for Video non worked.
Resolved the issue by switching to wayland session within which fractional
scaling worked and i could disable it/switch to 100%.
When i after that switched to X11 session scaling was back to normal.
SideNote: when switching scaling in a VM i was running resolution was
reseting back to normal.
