Oh thats my bad then. I thought arandr would be able to set the refreshrate aswell.
[quote]The systemsettings monitor settings work. I can change it. The problem is it doesnt save.
I just used suspend mode, and that was enough to kick it back to the original setting of 40hz.
This is very strange especially the behavior after standby is so unusual that I think it might be either the monitor forcing it or the driver being buggy and forcing it.
All in all does changing the refreshrate with the command line utility
xrandr -r 60
set the correct refreshrate ?
If yes you could create an autostart script which looks like this and has the file properties Executable set:
xrandr -r 60
The file should be saved in your home directory with the name .xprofile (with the dot in front of the filename [which basically says only hide that file by default]).
However this will only work for every login and will not fix the behavior after a suspend or for other users.
There are ways to completely overwrite the autodetected values within the xorg.conf configuration.
This however requires you to get those information necessary about the vertical refreshrate for your monitor. See this link about the information: https://wiki.ubuntu.com/X/Config/Resolution
especially the section Setting resolution changes in xorg.conf
