i'm experiencing what i think is a similar a black/blank screen in karmic after the ubuntu boot logo is finished on a dell studio xps 1340 laptop running a nvidia 9400m (+ 9200m but doesn't run due to no nvidia hybrid sli support) with karmic 64-bit. It happened after the reboot after installing about a 3 weeks of ubuntu updates (which i assume includes the above). Though the screen is black i can use my keyboard to login through the standard login screen and here all the standard ubuntu login noises (though i can't actually see anything as the screen remains blank). I can switch back to a text based login using ctrl + alt + f1 etc.
Also if i revert back to the nv driver the standard grpahical login appears and everything works as per that driver. I've tried both nvidia binary drivers 190.53 and 195.30 in the hope that it was a compatibility issue with newer software installed in the ubuntu update but neither worked. I tried going back through kernels 2.6.31-17-generic back to 2.6.31-14-generic but all kernels have the same problem. Please let me know if and what additional information to provide to assist resolving this issue.
