Title: Detected a new card, now Ubuntu hangs on the loading screen (.5 bounty)
Post by: Chick on June 23, 2011, 07:34:34 AM
Has anybody else experienced this problem? I switched one of the pci-e risers because it was defective, now the mobo is actually detecting it, but causes Ubuntu to hang on the loading screen with 5 red dots.

Giving a .5 bounty to those whom can help me solve it.

I'm just about as helpless as the next guy in ubuntu, but you'll probably need to boot to a command line shell and re-initialize your X setup.
But that's about all the detail I can give you on it!  Try some google or search on the ubuntu forums.
I think your problem is that X doesn't see the video card it's accustomed to and it's not that good at adapting.

Was it an existing card in the slot on the motherboard and you just extended it, or are you adding a new card to a new slot with an extender?

Existing slot.

Existing slot.

x16 or x1 extender?

Is it the only card in the system? Are all the cards in the system the same card?

I'd double check that the system works with the card in the slot, and even though it shouldn't make a difference, try having the primary display card onboard.

Once you get to the screen with the dots, do Ctrl-alt-F1.
Login, and type "lspci" (without the quotes)
Is the card included in that list?

If so, does the file /etc/X11/xorg.conf exist? You can test by typing:
Code:
ls /etc/X11/xorg.conf
Capitalization matters
If it says "No such file or directory" it doesn't exist, if it says "/etc/X11/xorg.conf" it does exist

I took the long way and re-installed Ubuntu...  :-[

Now cards 0 and 2 are being detected, but it says that it can't get any information out of 1 and 3 is just plain-out not detected.

Yeah, I have 4 cards but only 3 show up.

In that case, it sounds like a hardware/bios issue - make sure all the cards are seated properly, bios is configured etc. Sadly, I'm not too much help in that area.
lspci should report anything whether the drivers are sane or not.

Sometimes the kernel logs (at /var/log/kern.log) can hint at the problem. Running:
Code:
grep pci /var/log/kern.log
will search for pci related messages in kern.log. Look for error messages - they might be helpful.

Anyway, I assume you made it past the 4 dots after a reinstall?

Yep, it worked after the reinstall, I'll go look in the logs.

I think I've found a problem: "pci device is not a vga device"...

*sigh*, now grub cannot read a file, I guess I have to boot from the live cd and copy files again..

Figured it out, two of my pci risers were defective...

LOL, sorry for wasting you guy's time. :(
