HELP! Parallels 8 Tools Update = Linux Mint 15 Hang!

Everything was working fine running Linux Mint 15 MATE Parallels 8.0.18608-r898384 on Mac....that is, until I decided to install the Parallels Tools Update it indicated was available on 7/24/13. The tools installed fine, but upon reboot it boots to the Mint logo, and then I get the waiting cursor and it just hangs there with the cursor animation going but black screen behind it. I've managed to login in console mode, and it looks like Parallels has messed up my X server, as when I try "startx" from the console, I get this:

I've tried
- removing (renaming) ~/.Xauthority
- removing /tmp/.X11-unix/*
- sudo killall mdm
- /etc/init.d/mdm stop (but it keeps spawning new mdm processes anyway)
- sudo apt-get install --reinstall xorg
- sudo Xorg -configure, but I get this error:

So I run sudo rm -rf /temp/.X0-lock.

And then I run sudo Xorg -configure, but get this:

Any ideas?

Thanks, Parallels Tools Update!
