Re: Problems configuring my Nvidia card

Silly question, but have you tried running nvidia-settings (as root), set up you monitors and then saving the configuration?

Re: Problems configuring my Nvidia card

Yes, i already ran all the default nvidia settings and tried the GUI config. The problem is with some level of the driver not letting me display at the correct resolution. The GUI settings also show that same list of resolutions for the DVI output

Re: Problems configuring my Nvidia card

Which Nvidia graphics card are you using? Also, are you using a DVI to D-SUB (VGA) adapter? I remember having the exact same problem when using this adapter.

Re: Problems configuring my Nvidia card

Its a GTX 950, and no I'm not using any adapters. Im also using the standard Nvidia drivers.
