ati Mobility M6 LY catalyst

I've got a laptop with an ATI Mobility M6 LY card in it.  I installed the catalyst drivers and at first the screen would blank out before I could logon.  I fixed this by disabling KMS with "radeon.modeset=0".  I can logon now but startx puts my screen on a resolution it cant handle.  Upon further inspection the xorg.conf is missing and running aticonfig I get the error that no supported adapters are detected.

Re: ati Mobility M6 LY catalyst

manually edit your xorg.conf, this should be enough:

Section "Device"
 Driver "fglrx"
EndSection

I doubt your card works with fglrx though, it's quite old model.

M6 is not supported by catalyst, but it works just fine with xf86-video-ati. Just use a sane video boot option. See https://wiki.archlinux.org/index.php/In … small_area.  < that can cause black screen too, and it's not intel spesific even tho the wiki seems to think so

Yeah the open source drivers work ok, with no screen blanking. I just couldn't get tv-out working, which is important as the backlight is out on the screen.

$ xrandr --output S-video --mode 800x600
