I also have a freezing problem with Ubuntu 13.10 Here is what I posted this morning in the "General" forum:
Hello, my system randomly freezes when I login with the Ubuntu (default) desktop but does not when I use the Gnome flashback (no effects) desktop. I haven't login using the regular Gnome flashback desktop. The freezes happen doing simple things. It did also happen with Ubuntu 13.04 I have an Nvidia GeForce GT 240 (GT 215) video card I did a system test and what got tested passed Memory 7.8 GiB Processor Intel Pentium(R) D CPU 3.20GHz x 2 Graphics Gallium 0.4 on NVA3 OS type 64-bit Disk 23.6 GB -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1242767 Title: computer freeze trying to exit "gnome-control-center" Status in “xserver-xorg-video-nouveau” package in Ubuntu: New Bug description: 1) Description: Ubuntu 13.10 Release: 13.10 === 2) gnome-control-center: Installed: 1:3.6.3-0ubuntu44 Candidate: 1:3.6.3-0ubuntu44 Version table: *** 1:3.6.3-0ubuntu44 0 500 http://us.archive.ubuntu.com/ubuntu/ saucy/main amd64 Packages 100 /var/lib/dpkg/status 3) I expect to be able to exit System Settings (gnome-control-center), without freezing the computer 4) Clicking on the "X" to exit System Settings, the computer froze.
