xorg won't start - no screens found

i installed xorg-x11 and when i run startx, it says there are no screens found.

seems the customary thing to do is paste the wgetpaste url of the log and some lspci info.

Looks like you're missing video drivers.

Are you planning to use fglrx ati-drivers (closed source) or xf86-video-ati (oss) drivers? Or do you want to stick (or have to stick) with FB/VESA drivers?

What do you have as your make.conf's VIDEO_CARDS statement? You should set the video card you have there, either VIDEO_CARDS="ati" or "fglrx" and re-merge --oneshot xorg-drivers.

thanks for the response. i plan to use whatever video driver will work for x/kde. i had VIDEO_CARDS set in make.conf to radeon, but i change to ati. i re-emerged xorg-drivers, but it didn't look like it did much and sure didn't help. i have the same output when i run startx.

Make sure you also use --deep and --newuse when emerging them, did the xf86-video-ati package get built?

i went through the long rebuild of emerge --newuse --deep --oneshot xorg-drivers. same error, no screens found.

i thought the radeon cards were open source and as such worked easily. this is challenging and frustrating to say the least.

If it still says "failed to load module, module does not exist" and remerged xorg-drivers with dependencies, then something is really screwed up in your make.conf:

in my case

I had
VIDEO_CARDS="nv"

and got it up & running

Since I have an nvidia card, Xorg.conf documetation states
that it shoud properly be:

VIDEO_CARDS="nouveau"

in your make.conf

after changing I did

# emerge --update --deep --newuse @world
# emerge --depclean
# revdep-rebuild

Now my Xorg.0.log tail reads:

I'm trying to find out more on KMS. after that
the lines are the same as yours

eflothmeier, since you got the userland driver built properly, the problem is a bit different - you still have a kernel problem. When building the kernel, you need DRM_NOUVEAU enabled, and it looks by default it uses KMS.

Yes,
I fixed it. KMS (Kernal Mode Setting) wasn't set up properly
in the kernel. I rebult it with the nouveau setting. Now the screen
pixel resolution is so high that it's hard to read.

I also have a radeon/ati box, and I remember having to
install firmware blobs to get it to work
