A bit more information: I performed an strace as well and got the same results as Chris does above. I took the IOCTL code and decoded it according to the documentation in the Linux Kernel. Based on that, it decodes to a Read/Write IOCTL in driver 'd', function 3A. Driver 'd' is assigned (primarily) to the drm driver. The drm driver uses function 3A for DRM_IOCTL_WAIT_VBLANK. Unfortunately, that's about where my understanding died.
I'm trying to figure out where it's called in the X code, but I'm not sure where to track it down. Maybe, however, this will help someone else figure it out. :) -- [intrepid] X locks up or crashes when screensaver activates https://bugs.launchpad.net/bugs/262605 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
