Steam OS AMD Workaround Method 1
The method below is [tested] and is only suggested if you do not have a test system handy.
Goto amds site and download the catalyst drivers. Then you need to unzip them with the unzip command chmod +x the .run file, and run it with –force and it installs itself with a nice little windows style install gui. After the installation is complete login to steam and launch steam, accept the EULA and logout of steam and switch to desktop/desktop. Download catalyst drivers here with iceweasel
First down the AMD Beta Linux driver from AMD’s Main Site. I had to add the debian repos to install unzip. Add the following to /etc/apt/sources.list
I had to add the debian repos to install unzip. Add the following to /etc/apt/sources.list
deb http://http.debian.net/debian wheezy main deb-src http://http.debian.net/debian wheezy main deb http://http.debian.net/debian wheezy-updates main deb-src http://http.debian.net/debian wheezy-updates main deb http://security.debian.org/ wheezy/updates main deb-src http://security.debian.org/ wheezy/updates main sudo apt-get update sudo apt-get install unzip unzip ~/Downloads/AMD<tab> chmod +x amd.run sudo ./amd --force
You may have to install the fglrx drivers or other applicable packages the AMD installer complains about. To do this run the following:
dpkg --get-selections | grep fglrx* sudo apt-get purge fglrx*
Then Run the installer again for AMD. That should get it installed. reboot and then run the ~/post_logon.sh file under /home/desktop. Choose “run in terminal” and enter the sudo password for desktop, “desktop”
If for some reason you get a black screen after reboot, thanks to commenter Ben Stovel, perform a CTRL+ALT+F2 to enter virtual console TTY2. Once there log in as desktop and run the installer again then reboot.
If for some reason you still get a black screen, I found an interesting “trick.” Once you reboot after issue 1, if you hit any key on your keyboard, you’ll notice a PC beep if you have an internal PC speaker. What is on the screen is actually the Steam EULA (End User License Agreement) screen. Carefully hit + + . The Steam updater will start, and install the update. Resulting in… the SteamOS Welcome Screen!
