[ovirt-users] Cannnot change display resolution using spice

[Станислав Ефремов]

No windows guest. oVirt run over centos 7.3, thin station run over Ubuntu 16.04.2, vm run over fedora 25 workstation with default gnome3 and gdm display manager. Thin station successfully connect to vm over spice and I can change display resolution in vm, but gmone3 is heavy so I decide to change display manager and desktop to lightdm and lxqt. After that I cannot change display resolution in vm even I go back on gnome3 and gdm. My skill isn’t enough to see root of evil. Most of logs seems legit to me, no warning, no errors

If you are trying windows, you will need to install the appropriate drivers to make it work. Any linux (well except ubuntu) works out of the box, at least ones I have tried.
