change X resolution to 91 dpi, system boots gdm
 

Ive been doing some googling about how to change the resolution of my systems X configuration. So far what I have found deals with changing xdm and starting it with startx. That is all well and fine if thats the only optional way of doing it. I could probably find how to switch from gdm to xdm without too much trouble.
Before I consider doing that however, I am curious as to whether or not anyone knows what I need to edit when working with gdm. If there is more to it than that feel free to elaborate.
Thank you in advance

If you want to change resolutions, you just need to add the resolutions in your /etc/X11/xorg.conf file. There is a section to add resolutions under the default DPI setting.

You can also test the resolutions by doing...


Ctrl + alt + (+ or - on the number pad)

The Debian command to change X settings is "dpkg-reconfigure xserver-xfree86". If you've already manually edited your /etc/X11/XF86Config-4, the dpkg-reconfigure program may not write down the changes and you have to keep maintaining XF86Config-4 manually. So, if you're a newbie, it's safer to make all changes via "dpkg-reconfigure xserver-xfree86" and not to mess with XF86Config-4.

Yes, I understand how to change the resolution on my monitor between 800x600 1024x768 etc, but what this has to deal with is having fonts that aren't anti-aliased. What reminded me of 91 dpi was when I opened GIMP the other day and said that I was running at 81 dpi also noticing how gagged my fluxbox fonts are, That is when I remembered that my previous setup ran an 91 dpi. This is what I want to know how to change.
thanks again

One way to set default dpi for fonts is to create ~/.Xresources file and to make the first line similar to this: Also the order in which the 75dpi and 100dpi fontpaths are listed in /etc/X11/XF86Config-4 may affect the fontsize in some apps -- the fontpath listed first is used as the default size. Unfortunately the order of fontpaths cannot be changed via "dpkg-reconfigure xserver-xfree86", so you may have to maintain XF86Config-4 manually from the moment you edit it using a text editor. But if you're familiar with manually configuring XWindowSystem, this shouldn't be a problem.

Great, thank you.
