I've had some luck using cvt to generate custom modelines which pushed the refresh up to 44hz which seemed to be a sweet spot in terms of being the most my graphics card (intel 4000 + GeForce GT 750M in optimus) could output reliably. To do this, first press Ctrl+ Alt+ F1, login as an 'Administrator' account, then run these commands: killall Xorgįor a while i used an ultrawide LG Screen If you didn't encounter problems, save the file, then restart X. If you encounter problems with the new resolution, please log out and then back in (worst case scenario: press Ctrl+ Alt+ Delete and then Enter to sign out.) Then, to test your resolution, do this: xrandr -output -mode Keep the quotes.įor the modename, run cvt |cut -d\ -f2, replacing the last placeholder with the output of this command.
Then, copy the output and replace the placeholder with it.įor the device, run xrandr|tail -n+2|head -n1|cut -d\ -f1, and replace the placeholder with its output. To test the resolution, first do this: xrandr -newmode Where Xx Y is your resolution and R is your refresh rate.
In the file change the parameters in according to your specs: Section "Monitor"įor the modeline, first run this command: cvt
In short: run xrandr and cvt like you did, then create the following file: /usr/share/X11//nf Along the lines of this, I was able to find some information:
