Whenever I resume, the display will always turn on initially, usually with a still image from some framebuffer console. Usually, the X server will then come to life after a short delay (e.g. with the unlock dialog from gnome-screensaver). Other times, however, there is a longer delay, after which the display shuts off (blacklight and all). The rest of the system remains functioning, and when I log in via ssh, I'll find the reported error messages in the kernel log. The display remains inoperable even if I do an Xserver restart, a VT switch, another suspend/resume, or a hibernate/thaw. A soft reboot, however, does reset the display. distro: Ubuntu 11.10 amd64 kernel 3.0.0-16-generic libdrm 2.4.26-1ubuntu1 mesa 7.11-0ubuntu3 xorg-server 2:1.10.4-1ubuntu4.2 xf86-video-intel 2:2.15.901-1ubuntu2.1 machine: Lenovo Thinkpad R61 7733A82 I've had about fourteen of these crashes in the past month and a half, and I've managed to collect debugging logs on most of them. However, this bug has defeated all my attempts to deliberately reproduce it. Sometimes I go for almost three weeks with no hangs, other times I get several hangs in one day. This may be related to changes in my usage patterns (how frequently I use suspend, how much time I waste on Youtube videos, etc.), but I haven't found any correlation yet, nor do I have any real idea of what to look for. Some observations I have made so far: -) Doing many suspend/resume cycles in a row (e.g. running pm-suspend 50 times in a script) is *not* sufficient to reproduce this bug. -) I once attempted to reproduce this bug by opening a large number of windows/applications at once, with the hope that this would stress the graphics system. However, it had no apparent effect on suspend/resume performance. -) This bug does not seem to depend on the kernel version. I've encountered these hangs with the 3.0.0 kernel shipped with 11.10, and I've also seen it with vanilla 2.6.38, 2.6.39, and 3.2.0 kernels. However, I never encountered this bug when running Ubuntu 11.04 and its 2.6.38 kernel. It would seem that userspace changes are key. -) This bug does not seem to be affected by the use of OpenGL compositing managers: the crashes continued even when I switched from Unity to Unity2D. I'll attach some logs from one of my most recent hangs. I've added drm.debug=0x06 to my default kernel command line, which wastes syslog space but ensures that verbose logging is on when a hang hits. The kernel messages are from my syslog (from which I've pulled out irrelevant non-kernel messages). All of these logs were saved shortly after the hang (while I was logged in via ssh). I've also set up some small scripts to collect logs and statistics with every suspend/resume, with the hope that this would help find what makes the difference between successful and unsuccessful suspends. Right now I only save dumps from xwininfo and xrestop, for lack of a better idea.
