During the install phase it would come up in 1024 x 768 mode. But at reboot after install, it had video problems and refused to go beyond ancient VGA mode... 640 x 480 pixels x 16 colours.
After some trial and error I rebuilt my linux kernel *WITHOUT* Bochs video extensions. Bochs video extensions allow the VM to "talk to the virtual bare metal" video. Without Bochs, the VM talks to VESA VBE, and the ArcOS system setup menu offers up to 2560 x 1600 x 16 million colours. My monitor is "only" 1920 x 1080. Maybe ReactOS is coming up OK but can't talk to the video because it expects standard VESA VBE. Suggestion; try rebuilding your linux kernel *WITHOUT* Bochs video extensions. If you have Bochs as a module, you may be able to "blacklist" it instead. -- Walter Dnes <[email protected]> I don't run "desktop environments"; I run useful applications
