A few days ago I managed to install Gentoo 2006.1 on my old laptop from stage3. However, problems started to arise after installing X and gdm. Now whenever I want to switch from X to a tty and try to login (I get to the point where you type the username) the whole system crashes with a message similar to this:

When I've disabled xdm/gdm from running at boot, everything seems to work ok. I haven't checked but I think so as I didn't have these crashes before GDM and Xorg. Through Xorg everything seems to work but when you get out of X things start breaking apart. I get similar crash when trying to power off the laptop via GDM, but if I power off via xterm there's no problem.

I've tried recompiling Xorg and GDM, even the kernel (I've tried several different kernel configurations), but I don't seem to get rid of that annoying crash.

Any help when it comes to solving this problem is welcome and appreciated. :)

Thanks for the reply. I did try it, but it says there are no packages to be re-emerged. I also did a bit of research into the problem, it seems that I don't even have to type anything to the login screen for it to crash. When I switch to a tty and wait 2-4 seconds, the crash just happens.

Well this is probably a kernel problem. You shouldn't ever get an Oops message from the kernel.

Can you paste your ".config" file?

You can usually find it in a few places:
/usr/src/linux-someversion/.config
zcat /proc/config.gz > my.config
Or it may be in /boot/ as config-VersionNumber

Any idea if you can build a standard kernel (kernel-sources, not gentoo-sources)?
If you still get this crash, you may be able to post it as a bug to the Linux Kernel bug site at http://bugzilla.kernel.org/

You may also want to try disabling GDM.I believe you can use:
Code:
rc-update del gdm # Disable GDM
rc-update add gdm default # Enable it again.


To manually start the X server, type "startx"

Some updates: I emerged, configured and compiled the vanilla-sources and the problem doesn't seem to be there anymore when running vanilla-kernel so the problem was probably a misconfiguration in the gentoo-kernel. I haven't had time to compare the configs of the kernels, but I'll see if I can find some time to check them out.
