ATI radeon 7000 no DVI port in Ubuntu 8.1

Asked by w2co

I have an ATI Radeon 7000 card with VGA and DVI ports, just installed Ubuntu 8.1 and it has to come up in safe mode to even see anything on the VGA monitor. I really want the DVI port to function, but cannot even get the VGA to work correctly. My xorg.conf file is just plain jane generic see below:

# xorg.conf (X.Org X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the xorg.conf manual page.
# (Type "man xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# Note that some configuration settings that could be done previously

# here are ignored.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
# sudo dpkg-reconfigure -phigh xserver-xorg

I have installed the ATI drivers from add/remove but that just made it worse.
Can anyone please point me in the right direction?
I need the DVI port to function on this machine.

Ok I removed the latest ati drivers via package manager and now it comes up without safe mode, however there is only the VGA output only -no DVI. The ati binary drivers are too new for this card which is still good for DVI. How can I get the DVI port to activate? Thanks in advance for any answers.

The DVI or VGA ports have nothing to do with configuring anything in Ubuntu.

To use a DVI connection, use a DVI cable to connect the Graphics card DVI socket to the monitor DVI socket.

Yes with the Radeon 7000 dual port card (from 1999-2000) the DVI port does not become active until the driver is loaded, it will however default to VGA mode on power up and during post, etc regardless of os. I found out in my research that Win 2K was the ONLY os that the DVI port even worked correctly, and it has worked well. The ATI binary driver package in Ubuntu 8.1 does not support this card and will not work correctly even in VGA modes. So if you have this video card please remove the ATI binary package in package manager and it will work good in VGA modes using the built in generic drivers. You may also have to reset your xorg.conf file back to original install, but then everything's fine in the VGA modes only, just no DVI.
