Linux on PowerPC FAQ-O-Matic : Booting Trouble : The login screen is flashing!
	If you've just installed Linux and when you boot, the local login screen flashes real fast (and your window manager never starts), then there's probably something wrong with your XWindows install. XWindows keeps trying to start, takes over the screen, fails, gives it up, tries again, and so on. Try booting into single user mode (on Macintosh systems, put "single" as the kernel arguments for BootX), and start by editing /etc/inittab. Comment out the lines that start your X installation (near the bottom) by inserting "#"'s (hashes) at the beginning of those lines. Reboot back into multi-user mode, and you should be able to use the system, albeit without your XWindows installation. Take the time to find out what went wrong with it and possibly reinstall it. When you're done, just uncomment those lines from the /etc/inittab file. fconcolor@internet-frontier.net
	it might be that the Xconfigurator during install messed up try running Xautoconfig..... wackaxor@excite.com
	The problem may lie with your video card. Try plugging in your video cable into your Mac's built in video card (while it is powered off, of course! :-) The kernel can handle Apple' default video drivers, and some third party cards. Your card may not be supported yet. Sam spaceman@mindspring.com
	Hi all i get that flicker screen when i checkoff no video driver at bootx. is this related to my kernel? i just installed my new linuxppc 2000 for my g4 sawtooth agp with the dvi ati card. cheers claas fase.inc@web.de
	same thing happened to me- So I had the install CD, booted up with that, specified my partitions, and before "installing software" I right clicked on the x desktop (which brings up black box), got a shell window, and played around in /etc. It turns out there are some inittab things... one of them is what your default runlevel is- runlevel 5 (which the install defaults to) will start X11, run level 4 is not used, and run level 3 is "normal". edit the file and have it come up at run level 3. upon login, everything worked fine. After login, xinit, or startx, NO PROBLEMS! X windows worked great! KDE works great, so I don't know what the issue is. knuts69@hotmail.com
