I have followed this tutorial http://www.backtrack-linux.org/forum...ad.php?t=43665
When i used grub 2 i could fix the "black screen" problem after startx, with adding startx to /root/.bash_profile
in combination with editing the line with "i915.modeset=1" after "text splash vga" in /boot/grub/grub.cfg
After I downgraded to grub legacy, I have the "black screen" problem again
I can't edit the grub because there is no such line with "text splash vga".
Also it tells me some error with "i915" on the purple screen.
