How to change screen resolution in Linux (Debian) using xrandr

[timocarliermusic]

This is really well explained; the pacing of the steps makes it easy to follow.

Thank you Sergei. This helped when I was having problems getting my Debian Linux to work on my old monitor with only 1600x900 max res.

Many thanks for this video. Having used Linux Mint, where there is a graphical tool to make this really easy, I was a bit baffled by Debian.

lightdm.conf.d isn't in the folder you mentioned in Kubuntu 17.04. It's in usr/share/lightdm and in that folder there are several files, including 40-kde-plasma-kf5.conf. I don't want to edit this file in case I do something to by pc!

How do you stretch resolution for games like CSGO?

[anantha]

1. Run xrandr -q | grep "connected primary"
2. xrandr --output HDMI-0 --auto

If you have a specific desired resolution, use, for example:
xrandr --output HDMI-0 --mode 1920x1080

what desktop enviroment u using? is that xfce ?

It doesn't work. I'm in MX Linux which is Debian based. If I use say 2560x1440_81Hz I get a flickering and if I use anything higher such as 2560x1440_85 the screen goes blank. In Windows 10 the display runs 24/7 at 96Hz and it runs perfectly up to 120Hz. My display is a well known Overclocking monitor called a Yamakasi Catleap Q270. So cvt is calculating the numbers wrong? Am I correct? If so, how do I get cvt to calculate the proper settings correctly?

Don't work for me in Debian 11 :/
-> I fix it with another video that make the same step but put the xrandr cmd in this file ~/.xprofile
The video title is "FIX Missing or Change Screen Resolutions on Linux VMs / Computers by using XRANDR. (Linux Beginners)" on youtube.

My screen goes black out after setting custom resolution

This works very well for the selected resolution, but how to do for more resolutions and change them from the display.

The following simple configuration works for me, and when connected, my monitor automatically uses the correct resolution without any manual intervention.

sudo nano /etc/X11/xorg.conf
Note that this file may or may not already exist. Add the following:

Section "Monitor"
Identifier "VGA1"
Modeline "1440x900_60.00" 106.50 1440 1528 1672 1904 900 903 909 934 -hsync +vsync
EndSection


Then reboot. If all goes well, then things should just work.
