A very strange X problem?

[k0pp]

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

Hi and Welcome !

then my entire machine locks up.. Doesnt dump me to a shell, doesnt do anything but sit there frozen.

Does Alt+Ctrl+F2 drop you at tty2? If it does, post the output of this

sudo lspci | grep -i vga

No it doesn't :/ No combination of buttons does anything

I'd think to boot into the recovery console mode (with both cards inserted), then at the # prompt, type dpkg-reconfigure -phigh xserver-xorg , which should define both cards in any necessary configuration files (like xorg.conf).

Type reboot and cross fingers.

dpkg-reconfigure command doesn't configure Graphics Card in latest versions of almost all Debian based distros. It just configures Keyboard, mouse and a few other things.

Boot up in Recovery or Single User Mode and post the output of lspci command as I suggested earlier.

Now why does that actually make sense (for results I've been seeing, not from a "common sense" view)? Thank you for this little tidbit of knowledge.

I second that, knowing more stuff like this does not hurt.
Thanks for the info DC
