[Spice-devel] 2K/4K resolutions not available?

[Mike]

Hi Christophe,

	I was using just "spicec" as the viewer in full screen mode, but trying 
remote-viewer doesn't seem to make any difference (full-screen or 
windowed mode), it just scales the guest display (and results in blurry 
text) and doesn't actually change the resolution on the guest side. I 
checked and spice-vdagent/spice-vdagentd are running in the guest as 
well and the log shows connections to it being made...

Using the script Gerd posted to force xrandr to change the resolution 
does work for a few minutes, but as soon as I try to launch some 
applications like Libreoffice Writer it crashes X immediately. It also 
seems to cause all sorts of other strange issues with the window manager 
(title bars disappear and reappear, etc...)
