Just setup an OpenBSD 4.8 VM for VMWare Fusion. Can't seem to force X to any decent resolution. I attempted to try and use the VMWare tools for FreeBSD, but no dice.
Any suggestions to try and get at least 1280x1024?
Firstly, you can't use binaries or drivers for FreeBSD on OpenBSD. OpenBSD, NetBSD and FreeBSD are very different OS.
Respect to your problem with the resolution. You need configure Xorg, probably the problem is that you are using the driver "vesa" and no the driver "vmware".
Other suggestion: update to 5.1. OpenBSD enhances the hardware support with each new release.
If they are right, then you simply haven't configured X to use the full screen space (which is odd because it usually defaults to the best resolution). You should be able to change that in
More information would definitely help in diagnosing the issue, bit the above should lead you on the right path.
