I''m trying to run Ubuntu 10.04 LTS Desktop in HVM DomU. Everything looks fine, but the maximal screen resolution is only 800x600. When I change stdvga in guest config from 0 to 1 and set videoram to 16, I get maximal resolution 640x480. Is there a way to change maximal resolution for Ubuntu under Xen for at least 1280x1024? Using Xen 4.1.2 on the Ubuntu Server 12.04 Beta

Re: Is it possible to increase screen resolution of DomU?
I suggest you try more video memory. I was able to get much higher resolutions with 32M of videoram, though my HVM was Windows 7.

I tried to set up videoram=8 videoram=16 videoram=32 videoram=64 Maximal resolution is 640x480 anyway, and I can get only maximum of 16M memory in videocard despite of videoram setting. in DomU stdvga=1, videoram=8 lspci -s 00:02.0 -vvv 00:02.0 VGA compatible controller: Technical Corp.
