I use two resolutions - 1680x1050x60Hz for general usage and 1280x1024x75Hz for CS:GO playing. I have set 1280x1024 in CS:GO settings, but when it launches it sets itself at 60Hz.
For this moment I have found a quick & dirty fix:
xrandr --output DVI-I-2 --mode 1280x1024 --rate 75
This sets current display mode to 1280x1024x75Hz, but I need to do it before every launch of the game and I need to make these changes back as I close my game.
Here is my xrandr -q info:
muttley@muttley-desktop:~$ xrandr -q
Screen 0: minimum 8 x 8, current 1680 x 1050, maximum 16384 x 16384

Is there a way to make Ubuntu switch to correct refresh rate by itself? Like when I give this command to terminal:
xrandr --output DVI-I-2 --mode 1280x1024
It would automatically pick 75Hz over 60Hz (so when game launches in 1280x1024 it would start at 75Hz, even though 1680x1050x60Hz was set before).
I was thinking about removing those default display modes, so
xrandr -q
would give me this:
muttley@muttley-desktop:~$ xrandr -q
Screen 0: minimum 8 x 8, current 1680 x 1050, maximum 16384 x 16384
DVI-I-0 disconnected (normal left inverted right x axis y axis)
DVI-I-1 disconnected (normal left inverted right x axis y axis)
DVI-I-2 connected primary 1680x1050+0+0 (normal left inverted right x axis y axis) 470mm x 300mm

DP-0 disconnected (normal left inverted right x axis y axis)

But I didn't manage to get access to it (googled for many hours without any luck)
Sorry for my English (Not my native language :/)
Thanks in advance for any help, muttley
ps -u <yourname>
when the application is running?
