Ubuntu 9.04 with dual boot (Windows XP) my Ubuntu screens freeze up
Hello. Im running Ubuntu Jaunty Jackalope (9.04) with a dual boot to Windows XP. I prefer running in Ubuntu mode.
Recently, while in Ubuntu mode, the screens have started to freeze up. Sometimes it freezes up immediately upon boot-up and sometimes it freezes after some time has gone by. My mouse clicks do nothing and I can't change anything on the screen or even minimize a window. I have to push the power button and reboot.
When in windows mode, everything runs fine without any problems.
Does this call for a reinstallation of Ubuntu and, if so, how is this done? I could go back to square one and reinstall everything including windows but I'd rather fix whatever is wrong.
