This is Sirish from QA team.
We didn’t observe this issue in RHEL and SUSE during our testing in 8.98 release, we have well covered this scenario. Issue can be specific to Ubuntu 12.04.
As per the issue reported, user is not able to retain the display configuration after reboot and the enabled 2 displays always goes to Clone mode after reboot. Please note that if User is initializing the configuration file (amdconfig --initial –f) after reboot, all the setting will go to the preferred values and displays will get configured in Clone.
We can get all the commands for configuring the displays using: “amdconfig --help” command.
This issue have been haunting me for remainder year since I got this CPU with AMD. Just tonight, I finally got it working but in this step of order (important)
AMD Radeon and using Ubuntu Linux OS
1. Edit your GRUB file /etc/default/grub (Ubuntu based)
non-Ubuntu: try this command: $ find / -type f -name '*grub"' and you should find it
GRUB_CMDLINE_LINUX="quiet splash nomodeset"
"quiet splash" is an Ubuntu related but for non-Ubuntu: just use "nomodeset"
$ sudo update-grub
$ sudo reboot
2. Update your flgrx installation
$ sudo apt-get install -y fglrx-updates
3. Configure your graphic configuration with AMD Catalyst
$ gksu amdcccle
This line will open the AMD Catalyst as Administrator (you will be prompted for superuser password to use it and this is the only way to get this to work)
Do your configuration as per your preference and save the setting.
4. Configure your X11/XOrg settings
Open your display setting [ Launcher --> System settings --> Displays ] and configure to your preference. This will reconfigure your system so it'd merge with the new configuration set by AMD Catalyst.
AMD Catalyst is graphic adapter controller meanwhile System display configuration controls the X11/Xorg. With these steps above establishes the connection of configurations between adapter and X11, which will enable the updated flgrx to run.
"Ok, what was really the problem?"
The newer version of kernel have "standardized" the video mode setting but into inside of kernel. With that, it means kernel registers your graphic adapter first which in turn, prevented X11/Xorg being able to gain the control of this graphic. So, in order for your system to get the full control is to "inform" kernel to not register your graphic adapter, with this command: 'nomodeset'.
There were some reports that kernel version 3.7.10 and 3.8.3 doesn't do much but were solved by using 'modeset=0' (without single quotes when editing your grub).
Hope this helps
