SteamOS Black Screen on Boot

I've recently installed SteamOS on my friend's computer, and it ran "okay" initially (low frame rate and mysteriously dim screen), but after I ran ``` ~/post_logon.sh

Here are the hardware specifications for the laptop.

first of all what does ~/post_logon.sh script do? can you post it's contents on pastebin and then post the link here? also we really need to see the Xorg.0.log file to know what the error is. and maybe even ~/.xession-errors file as well. if you only have access to tty1 than you may be able to install pastebinit with

sudo apt-get install pastebinit

then issue the following to upload the log file using

pastebinit /var/log/Xorg.0.log

and

pastebinit ~/.xsession-errors

then write down the links it spits back at you and post those links here.

~/post_logon.sh performs the post-install customizations, deletes itself, then reboots into the recovery partition capture utility. (#9 on Custom Installation)
