I need some help, please. I use an ATI Mobility Radeon HD 6370 with proprietary drivers v11.8 in Ubuntu 11.10 64 bit and I can't get it to detect an external monitor through HDMI. Not with the Catalyst software nor with the "Displays" utility. I just want to set up a simple and straight forward clone display configuration to see my laptop output on my HD TV monitor. I can do this without any trouble in Windows 7 (same machine, dual boot) so I know there's nothing wrong with my hardware (laptop, cable or TV monitor).
I'm not sure what is going wrong here, but if it has anything to do with this, I can tell you that I have an xorg.conf file generated by
and it is exactly the following:
sudo aticonfig -f --initial
So, is there something I should add in there to make Catalyst detect my monitor? Or has it got nothing to do with it?
Identifier "aticonfig Layout"
Screen 0 "aticonfig-Screen-0" 0 0
Option "VendorName" "ATI Proprietary Driver"
Option "ModelName" "Generic Autodetecting Monitor"
Option "DPMS" "true"
Viewport 0 0
This is actually driving me insane. I´ve spent a whole day trying to work this around without much success. I did find out, however that if I run I get the following output
Apparently there are two adapters detected. The information section in the Catalyst GUI confirms this, however, the display manager only lists the 4200 adapter.
* 0. 01:05.0 ATI Mobility Radeon HD 4200 Series
1. 02:00.0 AMD Radeon HD 6300M Series
I thought I could sort this out with a new xorg.conf file generated by aticonfig --initial -f --adapter=all but that only resulted in X server failing to load at startup. I only got it working again by restoring the previous configuration.
All help is appreciated.
