Debian drivers for Intel HD graphics

Modern Distro's usually don't have nor need an xorg.conf file. You should be able to create resolutions and use them using the xrandr command. If you run xrandr from konsole you should get a list of possible options to the command. Also, using gtf you can get the parameters you will need to insert for your preferred modes:

gtf 1024 768 60

would output the modeline you need for 1024x768 resolution at 60Hz

Once you have them and tested them you can put the commands into a bash script and have that script run when you logon to your GUI. The 3rd post in Below Link shows you how you can use xrandr. You need just the first part of that post (not the make persistant part), as you can do that with the script which is easier and also more universal:

The problem actually was in the monitor. In some monitors the resolutions is ok in some other not. I dont know why this is happening

There can be several reasons for those, for example it often happens when the display isn't connected directly to the video card and there is a KMS switch between the PC and the display, so you can attach several PC's to the same display, mouse and keyboard. Those switches seem to reduce the display's signal to the PC and the PC then can't define what the display can output. The same thing can happen with some displays that may have a low EDID signal so again the PC has problems understanding it.


but as I mentioned in my earlier comment, you can add new resolutions to the PC using the xrandr command and then you can use those new resolutions with those displays where you have problems.

Nothing of the rest answers solved the problem
