Vid problems in X
 

So again I go searching for answers, and again I'm forced to appeal to the group. I got Slack 9 installed last week, and I'm having trouble with my video modes in X. I can't get anything less than 1600x1200 to run. If there's a 1600x1200 mode in the list, no matter which is listed first, it'll take it, and if it's not listed, I get the "no usable screens" error when starting X. I'm using a laptop, and that high of a video mode makes things very difficult to read. My card is an ATI Mobility M4 AGP that runs the Rage 128 chipset. I got my monitor specs straight from Dell and have the HorizSync and VertRefresh listed correctly in XF86Config. I also tried putting a custom Modeline in my monitor definition, but the X-log tells me that hsync is out of range. I'll be happy to post any config files and/or log output if it'll help. Thanks!

Go ahead and post your XF86config file. I had to tweak mine quite a bit to get things working properly. I will say that I found everything I needed by searching this forum. (This board is a fantastic resource)
What type of screen do you have on your laptop?

Thanks for your reply! I'm running a Dell Latitude C800 with LCD screen capable of 1600x1200 at 32 bit color. Don't know where Dell got it from, but I did find some specs on the dell website:
http://docs.us.dell.com/docs/systems...n/ug/specs.htm

Here's the XF86Config that I'm running right now. Note that even though the 1024x768 is listed first, X still runs in 1600x1200.

I've been looking all over for answers and can't find a thing. Thanks for any help you can give!
