With the 17X.xx versions of the Nvidia driver this problem disappear. However I discovered that this configuration is a possible solution if you don't want to update:
1) Put this in xorg.conf Option "PixmapCacheSize" "1000000" Option "AllowSHMPixmaps" "0" 2) Run this command after that X started: nvidia-settings -a InitialPixmapPlacement=2 (you will need nvidia-settings to run it) -- amsn crashes X when you try to change display picture with compiz enabled https://bugs.launchpad.net/bugs/190531 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
