nvidia - Low Resolution on 16.04 with EVGA GTX960 - Ask Ubuntu


the setup

dual boot machine (windows 10, ubuntu 16.04) evga gtx960 gpu. monitor asus v247h-p capable of 1920x1080, connected via dvi (also tried hdmi, made no difference).

install

in order install ubuntu had add nomodeset avoid black screen - ok, makes sense, didn't have nvidia drivers @ point.

the problem

install went smoothly (not first rodeo) gave max resolution of 640x480. used software update switch proprietary nvidia drivers (369, believe, i'm not @ pc). after reboot, max resolution 1360x768. better, not 1080p.

nvidia drivers appear loading properly, according xorg.0.log.

1st attempt

ran sudo nvidia-xconfig create xorg.conf file, rebooted. resolution down 640x480 max!

if delete xorg.conf allows 1360x768 again.

2nd attempt

added following lines xorg.conf, in appropriate places, per suggestions found online (i'm going memory here):

option "modevalidation" "nomaxpclkcheck" modeline... [from running gtf] modes... [modeline name gtf] horizsync 30.0 - 80.0 vertrefresh 56.0 - 76.0

and couple other things. can edit tomorrow include exact lines, if necessary. exact numbers used horizsync , vertrefresh might off here.

this allowed resolution of 1920x1080 there "twinkling" on screen. i'm not sure how else describe it.

next steps?

at point i'm not sure do. can't find evidence of else having similar issues setup.
