Comment 14 for bug 138415

In my bios (motherboard AD77 Inifinity KT400) there is no 512MB aperture size. The only options are 256m 129m 64m 32m 16m 8m 4m 2g 1g

 I have left it as before on 256M

Other agp options are
AGP Mode - 8X (cannot be changed)

AGP driving control - AUTO
x AGP Driving Value - DA

AGP fast writes - enabled

AGP Master 1 WS Write - Enabled

AGP Master 1 WS Read - Enabled

AGP 3.0 Calibration cycle - disabled

These bios setings plus Enamuale's xorg.conf settings applied i am getting no signal input to the monitor. (Monitor is CMV 221D LCD connected via DVI connector)

Also i can not use command line either Alt+ctrl+f2 etc, wont work. I can get in with recovery mode by pressing escape key during bootup and then reverting to the backup xorg.conf file and start again.

I am going to find a VGA cable and remove dvi cable and see if it work, also once i am in gui on the desktop i will post my xorg.conf file which gives no signal.
