Can't access monitor connected through DVI

baldurpet · 03-01-2009, 05:40 PM

I'm using Ubuntu 8.10 on a computer with two DVI sockets but it doesn't detect my monitor when I connect it via DVI, but it does how ever detect it when I connect it via VGA with a VGA-DVI converter (so there isn't anything wrong with the screen itself).

My /etc/X11/xorg.conf file is something like

Code:

Section "Monitor"Identifier   "Configured Monitor"EndSection

Section "Screen"Identifier    "Default Screen"
Monitor    "Configured Monitor"
Device   "Configured Video Device"
DefaultDepth   24EndSection

Section "Module"Load   "glx"EndSection

Section "Device"Identifier    "Configured Video Device"
Driver   "nvidia"
Option   "NoLogo"   "True"

What should I do? (btw, the computer I'm talking about isn't connected to the Internet so I had to type all the xorg.conf file by hand)

I had this problem with my monitor connected through DVI with the radeon driver, but worked with vga or a dvi-hdmi cable. Problem went away with the fglrx driver. So I don't know if this a is Xorg.conf problem, or an issue with the driver itself.

With the fglrx driver? Isn't that for ATI drivers (according to Wikipedia anyway)? I have the "NVIDIA accelerated graphics driver (version 177)" on my computer.

How did you get the fglrx driver? Did you download it or get it through automatic updates? Please help me solve this, I really don't want to use a VGA cable with a DVI converter.

Edit: I tried to download drivers at NVIDIA's home page but I got the message "We're sorry, the NVIDIA Smart Scan does not support your system at this time. Supported operating systems: Microsoft Windows 98, 98SE, ME, 2000, XP, 2003, Media Center and Windows Vista." Where do you think the problem lies? In the graphics card? In the driver?

Yes, the fglrx driver is for ATI cards. I think you want the nvidia-glx driver and nvidia-kernel-source module. Ubuntu should have it in the repository in the non-free or restricted section. You might have to add that to your repository.

Could you give me a little help on how to do all this? Do I just need to sudo apt-get those drivers?

You install the Nvidia drivers with System>Administration>Hardware Drivers. If you already have version 177 installed you just need to go to Nvidia settings to set up your monitor. (sudo nvidia-settings) You will need to connect a VGA monitor with your DMI monitor until you get the DMI monitor setup. You need to open nvidia settings as root so that you will be able to save your settings to your xorg file, otherwise you have to go through this every time you boot.
