I can confirm this happening to me too. Every now and again before 13.10, but very often since I did a fresh 13.10 install.
Everything freezes with no clear relation with user actions or opened programs. Sometimes I can switch to console with ctrl+alt+f2 and restart lightgdm but it just delay the freezing for a while because next time it will completely freeze forcing me to perform a hard reset. In adition, I have also noticed a very high rate of firefox breaks since I upgrade to 13.10. I have always been running an updated system with no extras out of the installed repos. It is coming out so frecuently that it is driving the system unusable for working purpouses. Just sometimes it can keeps running for a few hours with no problem. The weird thing is that it occurs when I'm doing the exact same work with the same programs than when it freezes. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1184451 Title: Ubuntu 13.10 random screen freeze while Normal OS activites Status in “xorg-server” package in Ubuntu: Confirmed Status in “xserver-xorg-video-nouveau” package in Ubuntu: Confirmed Bug description: I have recently, re-installed fresh ubuntu 13.10 distribution release.
