Hi, well, I'm lost totally here. I don't know how to start my X Window system with proprietary Nvidia driver. I must to use it because an application needs it. I tried in the Xwrapper.config the 'needs_root_rights = no', I tried to remove ~/.xinitrc to start X with defaults, I tried the '30-nvidia.conf' with Section "Device" Identifier "Nvidia Card" Driver "nvidia" VendorName "NVIDIA Corporation" Option "NoLogo" "True" EndSection but just can't to start X Window system with 'startx' command. I have installed: kernel version: 3.14.31-1-lts nvidia-304xx-lts nvidia-304xx-libgl nvidia-304xx-utils I look into '~/.local/share/xorg/Xorg.0.log' and see that that Xorg even not see the nvidia driver!? Xorg tries to load other modules but nvidia not, and finally gives the following error message: 'No drivers available Fatal server error: no screens found(EE) Please, help me to solve this problem. -- Regards from Pal
