I faced constant system freezing in Ubuntu under both Unity and Gnome shell. So I came to Arch. In Arch also im facing the same issue. I tried many things in these forums but nothing helped. Please help me. The system hangs constantly and the mouse barely moves. When I press ctrl+alt+f2 it takes several minutes to go to the terminal and then I can reboot. Please help. My GPU is GT640 2GD3. Im now running Ubuntu 14.04 and nvidia 331 drivers. Here’s the output of dmesg :
