Ha! Now during boot I get the usual messages, until it tries to re-export directories for NFS kernel daemon... I get this over and over again:
* Reloading /etc/samba/smb.conf...
Well, while I'm still writing this, I've managed to figure out that it was because I tried to manually change the xorg.conf file to reflect that I have an nvidia card, and tried to get it to use that instead of the awful vesa driver. What gives? I just realized that I don't even have the nvidia module, though I had it installed before I installed LinuxMCE. It was the only thing I set up before I installed it. Doing a lsmod | grep nvidia pulled up nothing, and modprobe nvidia says "Module nvidia not found". Wow, wasn't expecting that.
Do I need to force a reinstall of the nvidia module?
