Public bug reported:
Steps to reproduce:
-Set up a VM in Ubuntu 12.10 (select that the VM is for Linux, Ubuntu 12.10)
-Install from ISO:
http://iso.qa.ubuntu.com/qatracker/milestones/243/builds/30910/downloads
http://iso.qa.ubuntu.com/qatracker/milestones/243/builds/30907/downloads
-Follow Testcase "Install (entire disk)"
http://iso.qa.ubuntu.com/qatracker/milestones/243/builds/30910/testcases/1300/results
What was expected?
At step 10 a map of the world (timezone setup) should be shown
What happened?
KVM shows artifacts on the installer world map and after the installation is
over, lightdm unity-greeter, and desktop wallpaper all have this issue (see
attachments).
Why does it happen?
When creating the machine in the Virtual Machine Manager selects cirrus as
default. I've noticed this conflicts with the installation.
What is the workaround?
Change the video emulation setting to vga or vmvga (more resolutions).
Additional comments:
The following emulation modes have issues:
cirrus - artifacts
qxl - black screen. 100% CPU Usage.
xen - black screen
What should be done to fix this bug?
-Change the default video emulation settings for Ubuntu
-Fix cirrus emulation (and possibly qxl and xen)
