> sudo apt-get install nvidia-current-updates nvidia-settings-updates > sudo apt-get install nvidia-current-updates-dev Edit /etc/default/grub and add vmalloc=256m to the GRUB_CMDLINE_LINUX_DEFAULT parameter list > sudo update-grub Then I tried to fix the problem with: > sudo apt-get install ubuntu-drivers-common=1:0.2.91.4 nvidia-common=1:0.2.91.4 but still does not work. dpkg -l | grep nvidia gives: ii nvidia-304-updates 304.117-0ubuntu1 ii nvidia-304-updates-dev 304.117-0ubuntu1 ii nvidia-304-common 1:0.2.91.4 ii nvidia-current-updates 304.117-0ubuntu1 ii nvidia-current-updates-dev 304.117-0ubuntu1 -dev ii nvidia-libopencl1-304-updates 304.117-0ubuntu1 rc nvidia-libopencl1-331-updates 331.38-0ubuntu7.1 ii nvidia-opencl-icd-304-updates 304.117-0ubuntu1 ii nvidia-settings 331.20-0ubuntu8 ii nvidia-settings-updates 331.20-0ubuntu8 Any help?
