I have a newly installed gentoo system. I have been googling for 2 days. lots of info not sure what to do.

Here is the problem. I can only get X to work if I change my default color depth to 16 or lower. Then it will only display resolution of 640x480. I noticed some errors in my XFree86.0.log, in particular it is only finding or using less than 1 mb ram for video(X runining on slack finds 32mb) below I have excepts from my XFree86.0.logs, I did not think you would want to sort through the whole thing.

shanenin, check your kernel configuration. Are you sure you have AGP support (it looks you're using AGP card) and your graphic card driver compiled?

Yeah, Mara's on to something. I had to recompile the kernel with the agpgart support for my Intel i810. Check my same username on forums.gentoo.org ...you'll find a couple threads where I got the instructions how to do that. It's running really nicely since I did that.

Good luck,

Dave

I do not have an agp slot in my mother board, does that mean I do not use agp?

I noticed is slackware when I run lsmod agpgart is loaded, does that mean I must use it?

Can I add agp support using the command #make menuconfig ? I looked in there but did not see an option for it

Is it an onboard AGP card? Unless it's really old, I don't imagine it would be PCI.

It was in make menuconfig, but exactly where I don't recall. It was a subdirectory. If you check my posts on that other forum, someone there mentioned where it was.

lets assume your kernel is already compiled with agp support. go to the konsole and type (as root)
insmod agpgart
if it spawns some kind of error (like cant find agpgart), that would mean you need to recompile the kernel.

I needed to compile my kernel with agp support. "compiling a kernel" sounds intimidating. I had know idea how easy it was, espesially with the tool make menuconfig. Thanks for everyones help :-)
