Maybe I can add some information: Got the same problem as Michael Langerhorst on an Asus M2400 after an upgrade vom Jaunty to Karmic -- X freezes some seconds after having started the desktop after login. Ctrl-alt-del does not work, Alt-Fn1 etc. does not work, Sysrq-k kills X-Server, but the screen remains black and the machine is unusable (did not try to ssh it).

What I tried and what did _not_ help:

- kernel option nomodeset
- kernel options nomodeset and i915.modeset=0

What _did_ help however was using the latest kernel 2.6.29 from jaunty. Now X only crashes occasionally, and at least one occasion can be reproduced (klicking on a web site element in Firefox on a site not publicly accessible). There are some other pitfalls with using 2.6.29 in karmic, so this isn't a real solution -- it just gives you a machine somewhat usable. Have to go back to Jaunty.
