Public bug reported: Binary package hint: xorg
As background I'm running multi-GPU multi-session multi-head with 3 screens on two NVIDIA GPU Quadro NVS 290 (G86GL) cards (one on one, two on the other). Machine is a quad core with 8G ram and 8G swap. Individual gnome sessions on each screen (ie I can't transfer programs between screens and each screen has full menus). Occasionally after unlocking my mouse cursor rapidly flickers between screens and the machine is totally unresponsive at the console. Logging in via ssh and I can see load and cpu usage rapidly increases, memory usage also goes through the roof until all memory and swap is consumed at which point the oom-killer kicks in (or possibly Xorg crashes) , kills Xorg and I can log back in (with my session lost). In the mistaken assumption that I didn't have enough swap I increased it (from 2G to 10G) all this did was allow the machine to be a little bit more responsive for longer but Xorg still continued to consume memory, last time it got to 11.2G of virtual and a load average of 24 before I rebooted the machine. As a comparison, right now Xorg has 153m with load averages all at ~0.5. While I realise this may not include enough as is this is a reasonably regular (and very annoying) bug for me, if any further details can be collected at the time please let me know, I can (within reason) run anything as needed. ** Affects: xorg (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/780424 Title: Xorg unresponsive after screensaver unlock with Dual Head -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
