Hi, I agree with you about it. User should not be forced to one DE. 

Spice server now does not forward messages from spice client to spice server in case it detects QXL in the guest. I 'm not sure but changing this line https://gitlab.com/spice/spice/blob/master/server/agent-msg-filter.c#L107 to return "OK" may have an effect on your DE. 

Best regards,

Hi,

Thank you for the reply.

Yeah, I read about Gnome 3 and of course tried it but I just don't like the idea of being fasten to a particular desktop environment that is why

i tried to look into changing program code. It seems that it can be more flexible solution...

Just noticed that i seemed to implement it. I will check how it works with several monitors and then write about the result.

Best regards

Dmitry

Hello, 

I guess in this case the problem is in the guest's desktop environment. The auto-adjustment is implemented in Gnome and the recent KDE.

Dmitriy, you can change the environment of your centos 7 guest from Mate to Gnome to check out if it works.

Are you using qxl? Depending on your guest configuration, the
agent might not play a role in adjusting the resolution anymore.

For more details, you can check the implementation notes at
