That reads like a hardware failure to me. Unfortunately it will probably need to be repaired or replaced. > I logged a bug with Ubuntu - but no reaction yet. > https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-180/+bug/1127845 While Ubuntu is a fork of Debian and many things are therefore similar the Linux kernel in Ubuntu is a much different version than the one in Debian. Debian Stable Linux kernel version is 2.6.32 while Ubuntu's 12.10 Linux kernel is IIRC a 3.4 version. There have been a lot of changes there and they do their own packaging. This is an area where I would make no assumption about them being similar. You need Ubuntu expertise. Since you were using Ubuntu already it really only makes sense to use Ubuntu resources to debug it. Because reading your report you never mentioned installing Debian on your system so I don't see how this involves Debian any more than if you had installed Gentoo or Arch. The Linux kernels in those Gentoo and Arch are much more similar to Ubuntu than Debian. Sorry. Good luck! Bob
