Sounds to me like XFree86 is not being automatically started up and/or it is not in synch with your video card set up.
If you haven't already, get into the video setup section of Mandrake control Center. Switch to 'expert' mode. Don't be intimidated, 'expert' simply means you can see what is going on.
Make sure you test your resolution and color-depth, and opt to have X started up upon boot if that isn't now the case. The system will show you the various video attributes, including the XFree86 server which is probably set to SVGA if you are using 1024x768.
As long as you always test the video settings before accepting them, you can't really do much harm.
