sabayon 2.6.29 is not booting up, goes to blank screen
 

Operating System: Linux 2.6.29
Distro: Sabayon 4.1

Problem: When i boot my machine it just goes to a blank screen, it doesnt even show my login screen.

Last thing done: I updated the machine saying "equo update" and did a failed attempt to load printer drivers for samsung clp 510n

Resolution Attempt 1:
when i booted thru verbose mode, i figured out its getting stuck while loading/launching xdm.

Any help??

I'd suggest booting into runlevel 3 and sorting it out there. This is easy to do from grub, just add a '3' to the end of the kernel line (press 'e' key at grub splash to edit). e.g.

Having done this try logging in and starting X. If all this works, the problem does indeed lie with xdm (assuming you wanted to use xdm!).
