I'm having the exact same problem on a laptop with an Intel Mobile 4 Series Chipset Integrated Graphics Controller. Random X crashes all the time with 11.04, and I cannot discern a cause. Whatever was changed in the new Update driver, it had no effect.
After logging back in (after it kicks me the login screen) I can no longer connect to any network until I reboot. It's a very serious problem, as it makes 11.04 unstable. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/776772 Title: "Fatal Error: No screens found" in xorg.o.log -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
