Please let us know if you do otherwise this report can be left to expire in approximately 60 days time. Thank you for helping make Ubuntu better. ** Changed in: xorg-server (Ubuntu) Status: Triaged => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/533622 Title: "sudo strace -p $(pgrep X)" hangs system after a few seconds Status in xorg-server package in Ubuntu: Incomplete Bug description: I've tried "sudo strace -p $(pgrep X)" in a KDE konsole to see what Xorg was doing that may cause high cpu load. After a few seconds and lot of output, the system hung and I could not switch to another VT, but music kept playing in the background. Doing the REISUB sequence, the system restartet after Alt-SysRq-R or -E already. This was reproducible (I've tried it twice), the restart however appeared only once: it required a hard reset the other time. This is probably related to the generated output, since it did not happen on VT1 after reboot, where I've used "-o outputfile" though. Using "sudo strace -p $(pgrep X) -o /tmp/1" and "tail -f /tmp/1" also does not cause the hangup.
