I've been using Mint 5 for a couple of days now but just realized my display resolution is set at 1152x864 at 75 Hz, which makes UI widgets look rather obesed to me. I need to set the resolution to 1280x960 at 72 Hz, which is just not feasible via both the Screen Resolution Control Center applet and Screens and Graphics utility. I know this resolution+refresh rate combination works, since I used it in Windows for years. So, is there a way to force arbitrary values for display resolution and refresh rate?
I've done some searching and came across a thread that says something about entering the command 'xrandr' in terminal. Will it do the trick? This is my first Linux installation and I just don't want to break it.
Additionally, the following situations are true in my case:
1. Monitor type is correctly identified by the system (Samsung SyncMaster 753DF(X)).
2. Graphics card is correctly identified by the system (GeForce4 series. GeForce4-Ti4200, actually)
3. Proprietary display driver is installed and runs smoothly.

Re: Force Arbitrary Value for Resolution and Refresh Rate
You may have to use a modeline
But first - do you really get 75 Hz? My experience with nvidia cards is that they stop at about 50 Hz for LCDs but that would be painful on a CRT
Anyway edit xorg.conf
Add this modeline
to Section "Screen" which probably looks like this before you add
Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
Defaultdepth 24
EndSection
It should now look like
You should also add to Section "Monitor" so it looks like
Modelines must appear in both places
With Elyssa/Hardy the X server was almost completely remade and this sort of solution was supposed to be completely unnecessary
But - sometimes we must use it

Re: Force Arbitrary Value for Resolution and Refresh Rate
Yes, I do get 75 Hz.do you really get 75 Hz?
Perhaps its stopping at 50Hz only occurs with LCD panels.
Thanks for the clear walkthrough, Husse. You really are the man. I've taken a thorough look at my xorg.conf file, but it's far more complicated than what you said and thus I'm quite confused as to how to apply the changes into it. I've attached the file onto this post and hope you would help me with it.
Edit: I had to rename the file to xorg.conf.zip as .conf and .txt extensions are not allowed in this forum. Simply rename it to ditch the .zip extension.

Re: Force Arbitrary Value for Resolution and Refresh Rate
No, I've never used dual monitors in Mint. I guess the dual monitor configuration strings were generated by the nVidia driver installer since my graphics card has two output connectors (an analog and a DVI) and my monitor is hooked up to the DVI connector through a converter. But that's just a wild guess, though.Have you used dual monitors?
I don't plan to use dual monitors in near future, so please hit me.When I know if you want to use dual monitors or not I'll make you a suggestion

I booted my old(er) computer to copy it's xorg.conf - it has a Geforce 6600 GT and this is how it looks

Re: Force Arbitrary Value for Resolution and Refresh Rate
That should make mine an (even) older computer.I booted my old(er) computer... it has a Geforce 6600 GT...
Anyway, thank you so much for taking the time to come up with this. I'll try to append it to my xorg.conf.
