Just happened again, except this time the machine wasn't idle; I was editing a file with gvim. Xorg had been running for about two days.
Same message in the Xorg log: Fatal server error: Failed to map batchbuffer: Cannot allocate memory -- [gm45] Xorg crash when idle: Failed to map batchbuffer: Cannot allocate memory https://bugs.launchpad.net/bugs/588549 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
