8600gt, Ubuntu and DVI
Hello, this is my first post in this forum.
I have a problem in Ubuntu with my MSI 8600GT OC.
I use the DVI connection between my video card and the monitor.
When I install the Nvidia restricted driver, I can see the Ubuntu splash start screen, but after that, my monitor turns black ( it says "NO SIGNAL"), and I can't see the desktop. I know the desktop is loading, since I can hear the start sound.
If I go to console mode (CTRL + ALT + F1), I can see the text console, but if I try to return to graphic desktop, my monitor turns black again.
When I use the analog connector between my video card and my monitor, it works fine, but I don't want to use analog.
My computer is:
Asus M2N-E Sli motherboard
2 GB of ram
MSI 8600GT OC video card
Audigy 4 Pro soundcard
Xerox XR6 monitor, 1440x900

Thanks in advance!

Re: 8600gt, Ubuntu and DVI
When your screen turns black, go to console, log in as root (or as user and sudo) and run nvidia-bug-report.sh. Please post the results.

It is very hard to guess your problem without any real information.

I attached the debug file.
I see some lines with problems:

(II) NVIDIA(GPU-0): No display devices connected; falling back to: CRT-0
(WW) NVIDIA(GPU-0): Unable to read EDID for display device CRT-0


(WW) NVIDIA(0): Unable to get display device CRT-0's EDID; cannot compute DPI
(WW) NVIDIA(0): from CRT-0's EDID.

As I said before, my problem is that Ubuntu doesn't recognize my digital LCD monitor.

Hi , i have a similar problem with my 8600GT and Linux drivers

I have done a clean install of Ubuntu 7.10 , used the restricted drivers manager to install the restricted Nvidia drivers, but when i try and use them i get no display , regardless of using DVI or Analog cables.

My 8600GT has 2x DVI ports on it.


Biostar NF4 Chipset MB Socket 939
Jetway 8600GT
2gb Ram
"generic" 1280x1024 LCD panel

Note : everything works fine in XP ( i hate dual booting )

I have attached two log files generated by the nvidia-bug-report.sh script

one when using the Nvidia Restricted driver, and the other using the generic "nv" driver that comes with Ubuntu by default.

I have also posted other info in this thread on the Ubuntu Bugs page


it has output from lspci -vvv, xorg.log files, xorg.conf files , output from the "screens and graphics" applet after trying to test the Nvidia driver and having it fail.

I just attempted to install the Beta drivers 100.14.23 , and it did not appear to make any difference
