Can't change xorg resolution!

Where am I supposed to change my xorg resolution? I change it using xorgcfg -textmode and I edit the xorg.conf myself, but it doesn't change. Here's my xorg.conf:

Edit the Modes line in the Screen section of xorg.conf to appropriate values for your monitor (you can list several resolutions). For example (not necessarily appropriate for your monitor):
Modes "1280x1024" "1024x768" "800x600" "640x480"

The new resolution I specified in xorg.conf didn't appear in the xrandr options. I can change the resolution, just not to anything I specify in xorg.conf.

Someone's gotta know why...

Ok, I reinstalled Gentoo a week ago because of other problems, but I still have this issue. I'll repost my xorg.conf, and yes, I've already tried everything else that you guys suggessted. Here's that xorg.conf:

Out of curiosity, in your kernel configuration, under Device Drivers/Graphics Support, did you select
<> Support for frame buffer devices?

Did you select anything else on that page?

Yeah, I have enabled Support for frame buffer devices, VESA VGA graphics support, and Support for the framebuffer splash. They're not modules, though.

I'm no expert, but I have a couple of ideas for things you can try since nobody else seems to be offering anything:

Which kernel did you install? I have gentoo running on a laptop (2.6.13-gentoo-r5) and a desktop (2.6.14-gentoo-r5) and neither one had a specific "Support for the framebuffer splash" line in menuconfig.

Anyway, on my laptop the ONLY item I included under Graphics Support is the first line: <*>Support for frame buffer devices. NOTHING else on that page. On my desktop (which has an Nvidia chipset), I included that first line plus the next [*] Enable Video Mode Handling Helpers. Nothing else. On both machines, that was all that was needed to have the bootsplash working. In fact, the desktop did NOT work when I included "nvidia Framebuffer Support", so having extra items on that page can cause problems. If I were you I'd recompile the kernel with only the basic 'Support for frame buffer devices" & see if that works. (I don't think you need that "VESA VGA graphics support" in order to use the vesa driver in xorg.conf Section "device".) It only takes a few minutes to recompile the kernel, and you can always change it back if necessary.

Also, yours is a laptop, right? Try commenting out the HorizSync and VertRefresh lines in your xorg.conf. Those should not be necessary for an LCD screen. My laptop works fine with this monitor section:

Also, you might try expanding your "Screen" section some, like this:

Here's something else that may help you; probably better than what I posted above:

It seems that the 855resolution is the solution, but how do I use it!? I've tried all sorts of things and it won't change the res.

Have you tried using the i810 video driver?

Just for kicks, why not try
Driver "i810"

instead of
Driver "vesa"

in your xorg.conf.

Nothin going, folks. I tried 855resolution, and it's not replacing any modes in xrandr. I tried xorg 7.0, nothing. No other drivers work besides VESA.

I'll bet this is something really stupid, too.

So I'm stuck in a craptacular 1024x768? Damn.

How's this: I was using menuconfig a few days ago when I saw the option under 'Input Device Support' to change Horizontal Screen Res and Vertical Screen Res. Of course, I changed them to 1400 and 1050, respectively. Nothing happened, but that could be a stepping stone towards the solution.

The HorizontalSync and Vertical Refresh is probably what you need to play with next. Keep in mind this isn't like your resolution so thats why when you plugged in 1400x1050 it didn't work. What you need to do is try modifying this field in xorg.conf....

I changed them to all sorts of settings, but nothing worked. Is there anyway that I can change my resolution besides with xrandr?

I forgot to update the xorg.conf I posted above since I reinstalled gentoo. Here it is again:
