Public bug reported: Ubuntu release: KUbuntu 12.04 (beta) libdrm-intel1 2.4.32, xserver-xorg-core 1.11.4
In the Ubuntu 12.04 with the KWin option "suspend desktop effects for fullscreen windows" enabled, I often get X crashes. This usually occures when I just exit from a fullscreen application, before the usual KDE desktop should show up. Such thing usually happens with applications running under wine, but recently I got a similar crash with the usual KDE screensaver. X server just restarts and all unsaved work in my KDE session gets lost. In the Xorg.0.log.old I find some stack backtrace, which may differ from case to case, but it always ends in libdrm_intel. I attach a few examples below. I realize that these logs are possibly not very useful (there are only raw addresses), but I have no idea how to make X to dump more detailed backtrace, with full debug info. These crashes are rather well reproducible, and if someone explains how to get more detailed information, I will gladly do this. ** Affects: libdrm (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to libdrm in Ubuntu. https://bugs.launchpad.net/bugs/974041 Title: KWin option of auto-suspending for fullscreen windows often causes X to crash in libdrm_intel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libdrm/+bug/974041/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
