A very strange X problem?

k0pp · 04-09-2009, 09:54 AM

Alright guys.. I've spent probably 50 hours of the past 4-5 days trying to get this working... Basically, whenever my second video card is plugged in to (any) PCI slot.. kubuntu boots up fine all the way till KDM is about to start up, then my entire machine locks up.. Doesnt dump me to a shell, doesnt do anything but sit there frozen. Here's some specifics on my hardware

HP Pavilion a1020n
(Card 1) Onboard video card using the intel driver
(Card 2) Matrox Millennium PCI using the mga driver

Running Kubuntu 8.04.

I'd show the xorg.conf I manufactured, but I forgot to back it up when i rebuilt my system. So.. if there's any other info I can provide, tell me! Thanks

Check your bios settings. Disable the onboard one.

This is when it's handy to have a second PC to ssh to the one that's locked up. It's probably only X that is locked and it's a problem with your xorg.conf file. REM the line in xorg.conf that refers to your specific video card and add a generic card reference.

You could also run dpkg-reconfigure and choose generic video settings until you get X to work. Then you can troubleshoot the problem with your video card.
