[Solved] Blank screen after Xorg -configure

Just reinstalled Arch (had messed around with too many things on my old install, quicker just to reinstall) I've got to the Xorg -configure part of the guide but after doing that and trying to test the newly created xorg.conf i just get a blank screen. I've had a look at the file and can't see anything unusual. Also when booting up while all the services are starting some message comes up and something fails but it goes too fast to see it, how do I find this message once I've logged in? (would usually just go to system log viewer but have no gui yet)
I'm using the testing repo and the radeonhd driver.
My xorg.conf

Re: [Solved] Blank screen after Xorg -configure

Sounds just like my experience after installation -- the X server has been patched to remove the traditional background pattern, and the default config allows it to start happily without any input devices attached, so all you get is a black screen with no indication as to whether it worked.

To run X with a white background:

X -wr -config xorg.conf.new

To get mouse and keyboard (worked for me, at least):

Section "ServerLayout"
  # ...
  Option "AllowEmptyInput" "off"
EndSection

You know what's hilarious?

Thanks to the new Xorg's policy of disabling the ctrl-alt-backspace deal, once I test X I can't get back out of it. Brilliant.


And in the midst of such perfection,
I can't help but feel diseased.

You can switch to another VT and kill it, unless you happen to use a keyboard layout without the XF86_Switch_VT_* keysyms...

On the bright side, I learned how to use the SysRq key.

Maybe you've already figured it out (the thread is a couple weeks old), but in any case:

When you log into a plain X you get a couple of  bash-prompts (consoles); X exits when you exit all of them (just type "exit" at the respective prompts).

Add

Section "ServerFlags"
        Option "DontZap" "False"
EndSection

to xorg.conf to enable zapping i.e. Ctrl-Alt-Backspace.
