At the GRUB menu, add gentoo=nox to the kernel options, using the method explained by Alan. The advantage of this method is that it gives you a fully working system, running everything in your default runlevel except xdm. When you have made the changes and want to test them, /etc/init.d/xdm restart fires up X with no need to reboot. Note for the pedants: The xdm init script is run, but it checks for the nox flag and exits without starting X, that's why to need to restart it to run X. signature.asc Description: PGP signature

William Try this: Hold down Atl, hold down SysRq, press each of the keys in turn. The usual full sequence is R-E-I-S-U-B Reboot Even If System Utterly Broken When I had this issue, I would get a console when I got to the E or I. This is what each keystroke does tho: e sends TERM to all processes (except init) i kills all processes (except init) s syncs partitions u remounts everything ro b boots a box o turns off a box k saks a box - kills all processes on that vt r unraws the keyboard - takes it away from X. I hope that will get you back to a console at least. Then you can start doing the things others have suggested you try. Dale :-) :-)

Re: [gentoo-user] Frozen after Upgrade
Singe User (is from the kernel) you select the boot option via grub People refer to this as Maintenance Mode although to be frank every gentoo system is always in maintenence mode (kinda like perpetual beta) http://www.redhat.com/docs/manuals/linux/RHL-7.3-Manual/custom-guide/s1-rescuemode-booting-single.html It's the same idea just a diffrent distro; Once you are in single user mode verify all mounted partitions: #mount Then navigate to your xorg.conf; (under /etc/) and edit it to fix your issues or Navigate to your home directory /home/~username# and change the way you login by editing the approriate files (depending on your x display manager) Or conversly, if you are using a live cd: 1. mount your partitions a 2. ch root into your Gentoo install (you are now in single user mode) 3.

Anyway I also would try to follow Dales advise with pressing i during boot. There's all kinds of neat tricks you can do when booting or starting up. grub passes parameters and options to the kernel just like your shell passes parameters and options to a program you start. There's docs about it in /usr/src/linux/Documentation but be warned - they are written by kernel devs and most of them seem to assume the reader also knows as much as a kernel dev. So it can be hard going sometimes. A neat trick I use often is to append init=/bin/bash to the grub line. This runs bash after the kernel is loaded, not the usual init. You can't logout as normal though - try it and see :-) -- alan dot mckinnon at gmail dot com

I think most people missed the point that your keyboard would not allow you to do anything. I noticed that and knew exactly what position you were in. You also need to make a note about the alt sysrq key sequence as well. That can be a HUGE life saver. It will at least keep you from having to do a hard shutdown. I have had a couple times that I was stuck at the login screen and nothing else would get me back to a console. If you use the alt sysrq sequence, it will at least give you a sane shutdown, even if it is done blindly. Glad you got it working. Dale :-) :-)
