The problem disappeared when I switched to the nvidia propreitary driver. $ dpkg -l | grep nvidia rc libkwinnvidiahack4 4:4.10.5-0ubuntu0.2 amd64 library used by nvidia cards for the KDE window manager ii nvidia-304-updates 304.108-0ubuntu1 amd64 NVIDIA binary Xorg driver, kernel module and VDPAU library ii nvidia-common 1:0.2.83 amd64 transitional package for ubuntu-drivers-common ii nvidia-settings-304-updates 304.88-0ubuntu2 amd64 Tool for configuring the NVIDIA graphics driver
To me, this means that the problem is in the noveau driver since nothing else changed in my configuration. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1184451 Title: Ubuntu 13.10 random screen freeze while Normal OS activites To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1184451/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
