I can report that, unfortunately, this bug still exists on 177.70 and 2.6.27-2 (x86_64).
I also did some more testing, in an attempt to find out where in the initialization process the hang is occurring. I ran the command % time X >out 2>err & (sleep 3 ; pkill -9 X) & This sends the kill signal to the X server 3 seconds after starting. The results for the time are (roughly): real: 30s user: 0s sys: 30s So, the X server hangs for 30 seconds, doing some kind of work in a system call. Even though it was killed with -9, it doesn't quite immediately, hanging for 30 seconds. If I remove the "-9", then the X server takes 35 seconds, and shows the nvidia logo screen before exiting. I have attaches Xorg.0.log ** Attachment added: "Xorg.0.log" http://launchpadlibrarian.net/17181472/Xorg.0.log -- [G86GL] Latest NVIDIA drivers: X hangs with blank screen after logout. https://bugs.launchpad.net/bugs/258357 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
