Sometimes, when you’re trying to install the latest version of Ubuntu on your computer, you might get an error that says “aticonfig: No supported adapters detected.” You can fix this problem by doing one or more of the following: installing the newest drivers for your graphics card; upgrading your video card’s firmware; and finally restoring a previous configuration file. To continue with the installation, you can then go to System and select “Recover previous configuration.”
– Sometimes, when trying to install latest version of Ubuntu on computer, aticonfig error might occur. Fix this problem by doing one or more of following:
– installing newest drivers for graphics card;
– upgrading video cards’s firmware; and finally restoring a previous configuration file. To continue with installation process, proceed to Settings menu and click Recover Previous Configuration button.
To begin, we need to check if any additional packages are installed. Type the following command in Terminal:
$ sudo aticonfig –lsa
If you have not already done so, please be sure to check out our previous article on how to install Ubuntu using VMware Player or Workstation . The steps mentioned below will also work if you’re installing it with Wubi , but keep in mind that this method is much slower than installation via USB drive.
It is a necessity to ensure that older radeon drivers and their config files are not left
– sudo dpkg -l | grep fglrx —
This command will list all packages that have “fglrx” in their names, the problem is if you are trying to update your ati driver ubuntu version using ppa or via official website, these files might be left behind. To remove them completely run following commands:
sudo apt-get purge \*fgl\* && sudo rm /etc/X11/xorg.conf && sync; reboot –
The first line of code removes all packages with ‘fgl’ string inside its name and the second deletes config file for xserver. The last one just syncs things up so Ubuntu knows about it. Reboot computer after doing this.
– sudo aticonfig –initial -f –adapter=all
This line fixes the error you are getting because it tells your computer to reload all previously saved profiles or create new ones for hardware that was not detected earlier during booting process, this will also update xorg server configuration file so it knows about changes in driver settings. If this does not work try next options:
sudo aticonfig –initial -f –adapter=all –odgt; sudo aticonfig –set-pcs-str=”DDX,EnableRandr12,FALSE” && sync; reboot ; sudo amdconfig –input=/etc/X11/xorg .conf –tls=0 && sync; reboot
You might need to generate a newer version of xorg.conf file:
sudo aticonfig –adapter=all –odgt; sudo amdconfig –initial -f ; reboot
This command will generate a fresh new configuration and update your current one (xorg.conf) so it can recognize changes in the driver settings, if this does not work try next options:
At last resort you can always delete /etc/X11/xorg .conf file and restart your computer to get ride of all AMD drivers completely from system trying to install them again later or using different installation process like installing fglrx deb package instead of running amd installer through shell which is more complicated but it might fix some problems with X server that are difficult track down because they appear randomly.
