I'm trying to get X to start in 1400x1050 resolution. I've tried editing xorg.conf and adding "1400x1050" to all of the display settings, but it does nothing. I still can only go up to 1024x768. Any ideas?
Also the higher the resolution the lower the Refresh Rate. If you choose a VertRefresh that is to high you monitor will not handle it, unless you got a really expensive monitor?
Tried it with no luck. I know that Slackware supports this resolution becasue I ran it on SLAX by typing gui "1400x1050" at the command prompt. I'm on an ATI Mobiliy Radeon 7500 on a Gateway 450 ROG laptop, if that helps.

what X server are you running? One for the radeon, or the standard vesa framebuffer that gets set up by default?

To get my laptop (a Compaq with a Rage 128 based chipset) to work I had to configure it to use the ATI Rage 128 chipset directly.
If you can't get this by Monday, drop me a note at jas@jasnmis.com. I'll be happy to boot up my work laptop (also a 450 ROG) with Slax and play around with it.
I'm running the default, since I just installed Slackware last night. I just tried copying the gui shellscripts and config files from slax ("gui" "xconf" and "gui.conf"), but they did nothing in my Slackware 10.1 HD install. So I guess the problem isn't with the xorg.conf file. I guess I'll try downloading some new drivers.
I've decided to try Slackware again after about a month. I compared the xorg.conf files of slack and ubuntu, which I also run on my laptop. Slack uses the "vesa" framebuffer driver, while ubuntu uses the "ati" driver that is specific to my video card. How would I change the slack driver to ati?
install ati's drivers (sbing's slackware faq, stickied above in this forum, is a good guide). i've done it many times myself, and if you have any issues, i'll be around (along with many others who have done it before).
Another point that I didn';t see made (maybe I missed it) is that you should check out /var/log/Xorg.0.log if things don't work the way you want in regards to your X setup. This will tell you why the resolution you added was not used.
Another hint, grep is a handy tool, errors start with, (EE), warnings start with (WW), and errors about fonts are IPV6 can usually be ignored.
I didn't get any warnings, here are the errors that were not related to fonts:
Open APM failed (/dev/apm_bios) (No such device)
VESA(0): Bad V_BIOS checksum
VESA(0): Bad V_BIOS checksum
It also said:
*(II) VESA (0): Not using built-in mode "1400x1050" (hsync out of range)
and
(II) VESA(0): Not using mode "1400x1050" (no mode of this name)
It lists my graphics card correctly as ATI mobility Radeon 7500 in several places, so maybe the drivers aren't the problem. I guess I just have to know my horizontal sync? Is there any way to test for that? I'm on a laptop, so I don't have any documentation to tell me what it is.
I just decided to change the horizontal sync to a range from 31-94, and that did it. Will that have any negative effects on my monitor if the sync ratio is too high? I know that my monitor can handle up to 1400x1050 at a depth of 32.
Sorry I missed this. Like capnpayne said, looks like you got it. Bad values can damage your monitor, but in my experience, if the ranges are too far out of whack, you just don't get a display. It would be best to find the specs for your monitor, though. As capnpayne points out, the specs are usually just a Google search away.
