FGLRX and Dual Monitor [Solved]

[XNight]

Hello Community,

first of all, im new to Sabayon, but not new to Linux. Thats the reason why I am posting this here. Because i never had such a problem, and wasnt able to find any solution for it.

Well, im using Sabayon 8 64Bit KDE and have a ATI (or now AMD) Radeon HD5700. Sabayon installed the FGLRX driver out of the box and it is working well. fgl_glxgears gives me about 600FPS.
But my Problem is the following:
Im using two Monitors. One with 1280x1024 and the other 1920x1080.
The default setting is to Clone the Image, and im not able to change this. If I go to Settings and set the Position of the one Monitor to "Right of..." and click on Apply, nothing happens and the Settings change back to "Clone"
Catalyst Control Center is not Installed. I already tried "aticonfig --initial", what didnt help..
Thank you for your help. If you need more information about my system, just ask.
Greetings

Why don't you install Catalyst Control Center and try with that?

Code: Select all

equo install amdcccle

Or you could use xrandr commands to do it from the command line or from within a Bash script. Have a look in the article Xorg RandR 1.2 for both. Also, the xrandr help is quite good:

Code: Select all

man xrandr

Code: Select all

xrandr --help

Thanks for you help. Installing amdcccle worked. But i had the problem, that the root user wasnt able to use amdcccle. "Command not found"

For people who have the same problem: amdcccle can be found in
opt/bin/amdcccle
so simply use

Code: Select all

su -c "/opt/bin/amdcccle"

root user wasnt able to use amdcccle

The easiest way is to use amdcccle with sudo.

I have it as a favourite in the DE launcher. When I click on it to launch it, a window pops-up prompting me to enter the root user's password.

Related question, if that's OK: how do I make amdcccle's settings 'stick' between reboots? I can run it as root fine; I set it to 'Multi-display desktop with display(s) 2', and everything is fine. Reboot, however, and it comes back set to 'Cloned display from display(s) 2'.

I even did a line-by-line comparison of /etc/X11/xorg.conf before and after re-setting it to multi-display and couldn't see any difference. So whatever amdccle is setting, it's not doing it the way I expected it to!

Is there a way to preserve the settings across reboots?
