I can confirm this on 12.04 LTS and also on 12.10 with a very fresh install of ubuntu.
Its absolutely regardless which nvidia driver i activate (current, current-updates, experimental) the desktop freezes randomly with ativated nvidia driver. Sometimes the system freezes complete, desktop, mouse and keyboard are stocked. Sometimes only the keyboard and desktop freezes. and i can move the cursor but are not able to make the dekstop response do any kind of mouse interacting. If i change back to NV driver the system runs stable. Also this only happens the very first boot on the day. If i restart my system i can run it for hours without any problem. For now i have deactivated the nvidia drivers, hopefully someone can fix this. I also can confirm (but im not sure) that this must have to do with unity as im running a dualboot system with 12.04 LTS and Ubuntu Studio 12.10. On Ubuntu Studio which uses XFCE the system runs stable with the latest nvidia driver activated. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nvidia-graphics-drivers in Ubuntu. https://bugs.launchpad.net/bugs/1012879 Title: 12.04 Screen freezes, keyboard stops responding, mouse poitner continues to work Status in “nvidia-graphics-drivers” package in Ubuntu: Confirmed Bug description: Description: Ubuntu 12.04 LTS Release: 12.04 xorg: Installed: 1:7.6+12ubuntu1 Candidate: 1:7.6+12ubuntu1 Version table: *** 1:7.6+12ubuntu1 0 500 http://gb.archive.ubuntu.com/ubuntu/ precise/main amd64 Packages 100 /var/lib/dpkg/status Issue Under 12.04 screen freezes intermittently not evidently related to a specific application or user action.
