I created some profiles for different screen resolutions with scpm for my 11.1. In the real world I can select the profiles in grub and 11.1 starts with the selected resolution.
I did the same with a virtual 11.1 with VMWare Workstation 6.5. I´m able to select a profile, but 11.1 never changes the viewed resolution. If I look to the X-configuration the correct resolution of the profile is shown.
