Hi all,
since i went into trouble before knowing from this thread here last week, i tried to resolve the broken intel server today.
After a complete d-u from console, and also fetching fbdev and vesa, startx complained about missing /usr/bin/X. Which is correct, it's missing there. But there is a /usr/bin/Xorg. After appropriately changing the startx-script, kdm came back. I'm fine now.
Wanted to let you know, in case this issue arises for anybody else.
