Ubuntu – Fglrx installation without success – gl_conf issue


I followed the steps of this guide. I've installed the drivers without any problems with sudo dpkg -i fglrx*.deb.

The next step is Generate a new /etc/X11/xorg.conf file, but I can't do this due to the following reason:

When I enter sudo aticonfig --initial -f the terminal show me this output:

sudo: aticonfig: command not found

This problem is caused by an error with the symbolics links into the fglrx directory. Look at this section, where you can see -how to fix it- but it doesn't work for me. Why it doesn't? Because after I enter sudo update-alternatives --auto gl_conf the terminal show me this:

update-alternatives: error: no alternatives for gl_conf.

What I have to do to fix this problem? GC: ATI RadeonHD 6670

I have searched about this issu and understand that only fresh install of video driver can solve the problem. I think you messed up your driver. I have a fresh procedure to correctly install AMD driver but first refresh your repository cache with

sudo apt-get update && sudo apt-get dist-upgrade

Now begin with installation procedure.

sudo sh /usr/share/ati/fglrx-uninstall.sh
sudo apt-get remove --purge fglrx fglrx_* fglrx-amdcccle* fglrx-dev*

This will remove everything about AMD Driver. If any error occurred like file not found ignore it. Then, we need some dependent file to install this driver. Type in terminal

sudo apt-get install build-essential cdbs fakeroot dh-make debhelper debconf libstdc++6 dkms libqtgui4 wget execstack libelfg0 dh-modaliases

Then download your appropiate driver from here.

Extract the zip file in your desktop and open a terminal

cd ~/Desktop
sudo sh amd-driver-installer-*.run --buildpkg Ubuntu/oneiric

It will create 3 *.deb files in your desktop.

Now use sudo dpkg -i fglrx*.deb to install driver in your system.

Now use sudo aticonfig --initial -f to create a new Xorg.conf file. Now reboot with

sudo reboot

After reboot check your working driver with fglrxinfo. This is the right procedure to install AMD driver.
