Same here, did a fresh x86_64 install in VirtualBox (same version as @win8linux), anything higher then 1280x1024 results in a message general system error (native resolution on the host is 1900x600 (not available in the list))
Is there a way to display such a message from the accelerant ? I know only how to write to console.
You right if it is driver for real video card. User must see list of supported size only. We can not change video ram on modern hardware.
In our case, the user will be better to see that it can set a big screen size.
