Blackscreen after installing ati drivers BT5r3

Well i tried for the past 2 days to get past this problem but i cant find anything new that i didnt try.

All the grub switches and different Options in the xorg.conf but still they dont make any differense.
And also i tried all the guides to install the drivers to the letter.

My problem is after install ati drivers on my laptop. Lenovo edge 420 which have switchable gpu ati 6600M with intel.
There is not also an option in the bios that force the use of the discreet card only.

BT get stuck after the startx and the only solution is to delete xorg.conf to get into X.

I though to try also another distro just incase. With the same driver version linux Mint boots so its clearly not hardware or driver problem i think.

Any solutions for this?

Thanks alot.

How did you installed it?..Did you blacklisted radeon and removed radeon module?...How about posting the xorg.conf created?

Need more info....

As i said i followed the different guides on the internet.. either with the gui installer or with building the .debs and installing them individually.
Yes i blacklist radeon. i put radeon.modeset=0 to grub but it seems that these dont really play any role with latest kernels.

Xorg.conf is the default created after aticonfig --initial -f . Also i tried to put every different Options but again nothing works.

And it seems that few people have the same problem with backtrack

Please post the xorg.conf and the output of xrandr

backup your xorg.conf and try this new xorg.conf, do it manually using your favorite editor, I use nano:

Section "Device"
Identifier "Configured Video Device"
EndSection

Section "Device"
Identifier "Configured Video Device"
Driver "fglrx"

Try it..I needed the xrandr output to see Frecuency Refresh and Resolutions, but I'll try to set the most common resolutions as well as refresh rate (Frec)...
