The previous comment also means that this is not limited to 64-bit,
which was also common in the other reports.
** Description changed:
Binary package hint: xorg
- I have been experiencing X server crashes during suspend/resume testing,
- but no apport report was being left behind. The crash is due to heap
- corruption detected by glibc. This is logged to /var/log/gdm/:0.log.1
- and looks like this:
+ The X server has been observed to crash on a variety of different intel
+ chipsets. This most often happens during a resume (where the symptom is
+ that the system resumes to a gdm login dialog rather than to the user
+ session), but has been seen in other circumstances as well.
+
+ The crash is due to heap corruption detected by glibc. This is logged
+ to /var/log/gdm/:0.log.1 and looks like this:
