Ubuntu Linux with fglrx: unable to change screen resolution

Posted on 2004-11-17
Last Modified: 2013-12-03
Hi all. I'm a Linux newbie (winxp convert) and need some help setting up my video card drivers on Ubuntu Linux.

First of all, here is my core system setup:
Motherboard: MSI K7N2 Delta
Video Card: ATI Radeon X800 Pro (256 MB RAM).
Monitor: Sony HMD-A440 19"
Processor: AMD Athlon 2500+
RAM: 1GB dual-mode DDR

I used the Synaptic Package Manager to download and install fglrx and fglrx-control. fglrx is the free ATI driver, and fglrx-control is the control panel for it (which I have still been unable to find).

After I installed it, I rebooted and ran fglrxconfig, the configuration utility which rewrites XF86Config-4, the X-Server configuration file. This is the XF86Config-4 file it generated.

# XF86Config-4 (XFree86 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 XF86Config-4 manual page.
# (Type "man XF86Config-4" at the shell prompt.)
# This file is automatically updated on xserver-xfree86 package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xfree86
# package.
# If you have edited this file but would like it to be automatically updated
# again, run the following commands as root:
#   cp /etc/X11/XF86Config-4 /etc/X11/XF86Config-4.custom
#   md5sum /etc/X11/XF86Config-4 >/var/lib/xfree86/XF86Config-4.md5sum
#   dpkg-reconfigure xserver-xfree86

I did notice in the log after running fglrxconfig a message stating that no supported video card was found, although I am running an X800. However, in the list provided at the start of fglrxconfig, the X800 is not listed. I am probably foolishly assuming that my card is supported when it's not.

So I restarted xserver using the command: sudo /etc/init.d/gdm restart

Everything came up fine, but I wanted to change my screen resolution and this is the error message I got:
--> The X Server does not support the XRandR extension.  Runtime resolution changes to the display size are not available.

Anyone see anything, maybe in the XF86Config-4 file, that jumps out at you?

I haven't even TRIED playing a game with this yet :) I also tried the official ATI drivers but I'm still a linux noob, so converting the package to .deb and all that didn't seem to work for me at all... long story short I couldn't get it installed and the package manager was much easier.

Thanx in advance for your help.

    Can you do an lsmod so we can see what dirvers are running?

    lsmod doesn't show ati or fglrx, it still shows the default linux graphics driver.

    Also it's not a PCI card, it is AGP.

    Okay I reinstalled linux but now I have the same problem (XRandR extension not supported, runtime changes to resolution not permitted)

    Here is lsmod.

    try adding this source to
    your /etc/apt/sources.list:
    deb l-r-m/$(ARCH)/

    and following the instructions in

    "   1.

          sudo apt-get install linux-686 if you haven't already.

                or -k7 or -686-smp or -386... whatever matches your kernel.

          sudo apt-get install fglrx-driver

          echo fglrx | sudo tee -a /etc/modules

                This command won't have any effect until you reboot. To load the kernel module immediately, run sudo depmod -a ; sudo modprobe fglrx, but this will only work if you have already rebooted since upgrading the kernel. If it doesn't work, perform the next step (below) and then reboot.

          Edit /etc/X11/XF86Config-4 and change "ati" to "fglrx", perhaps with a command like:

                sudo sed -i -e 's/"ati"/"fglrx"/' /etc/X11/XF86Config-4

    Note (optional): If you are going to compile 3d applications, you will want to install the fglrx-driver-dev package

    Note (optional): You might want to install the fglrx-control package, which provides a control panel to configure graphics card options such as dual-head display (two monitors). "

    Accepted Solution

    There is a relatively obscure fix for this on the Ubuntu Forums.

    In your Xorg.conf, make sure this is included in the Modules section rather than "Load extmod"
    # This loads the miscellaneous extensions module, and disables
    # initialisation of the XFree86-DGA extension within that module.
    SubSection "extmod"
    Option "omit xfree86-dga" # don't initialise the DGA extension

    Let me know how it works out for you.
