880GA-UD3H video bizzareness

[drmike]

Howdy folks,

I just got a rev 3.0 880GA-UD3H running an 1100T processor.  It boots Ubuntu and runs just fine - I have run both 11.04 and 10.04 and the ram is working great.  However, when I try to switch over to text mode using any method (including ctrl-alt-F1, /etc/init.d/gdm stop or recovery mode at boot) there is no output on the either the DVI nor VGA ports.  It's as if UMA gets turned off.  However, it does not seem to accept keyboard commands either, except that after the screen freezes with ctrl-alt-F1, I can unfreeze it and everything works fine again using alt-F7.

Is this an 880G driver problem, or is there some setting in the BIOS I need to flip?

System:
880GA-UD3H rev 3.0
AMD 1100T hex core processor
16GB Wintec 3VH13339U9-8GK
NVidia GeForce GTX 560Ti (from PNY)

Note that the Nvidia card is for CUDA programming only, I won't be using the graphics.  The on board graphics is what I expect to go to the monitor.

Any clues from anyone with similar experience???

Thanks,
Mike

Hi,
I do not have the same exact board but try seeing if there still is a problem with a PS/2 mouse (if you are not already using one)
I run Ubuntu,Mandriva,Suse,and Mageia all with the PS/2 mouse ..
This is an off the cuff guess..
Goodluck,
jolphil

Thanks for the reply!  I found out that a lot of people have this problem - it has nothing to do with the motherboard.  The framebuffer is the problem, and I had to set it up so that the kernel knows how to talk to the screen correctly.  Here's the solution:

Step 2: edit /etc/default/grub as "root"
- Replace the following line (line number 9):

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

with this one (matching resolution appropriate to my screen):

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset video=uvesafb:mode_option=1280x1024-24,mtrr=3,scroll=ywrap"

- Replace the following line (line number 18):

#GRUB_GFXMODE=640x480

with this one:

GRUB_GFXMODE=1280x1024

Save the file and close it!

Step 3: edit /etc/initramsfs-tools/modules as root
Add the following line at the end of the file:

uvesafb mode_option=1280x1024-24 mtrr=3 scroll=ywrap

Save the file and close it!

Step 4: Run in terminal:

echo FRAMEBUFFER=y | sudo tee /etc/initramfs-tools/conf.d/splash
sudo update-grub2
sudo update-initramfs -u

Then reboot....


I didn't need step 1 listed.    So in case anyone else has a similar problem, this solution works on the above motherboard.
