Can start Xorg via SSH, but not via TTY

I have a Radeon 6870 and whenever I try to start X using just 'X' from the TTY it won't start. Here's what /var/log/Xorg.0.log says:

[   630.688] (II) modesetting: Driver for Modesetting Kernel Drivers: kms

But funnily enough, I ran 'X' from SSH, and it seemed to work just fine:

What gives? is radeondrmfb blocking it?

What if you start x with startx    ?

startx seems to start the server just fine, it just complains that I don't have xterm and all that. But I would really like lightdm to work instead of having to run startx all the time!

Re: Can start Xorg via SSH, but not via TTY

My point, that I had not even tried to make, is that 'X' is not the way to start X from the console.  You really want to use xinit or startx.  startx uses xinint.  xinit does a lot of magic having to do with screens and access to them.

I really suggest you set up a local .xinitrc and use startx.  Check out this article

Edit:  Sorry, I glossed over the lightdm bit.  I don't use a DM, so I really cannot help.   I did not see that as part of the initial question.

Re: Can start Xorg via SSH, but not via TTY

1. What's your X configuration? (/etc/X11/xorg.conf.d/ or /etc/X11/xorg.conf)
2. Try cleaning your X config by renaming files in /etc/X11/xorg.conf.d/ from xx-yyyy.conf to xx-yyyy.conf.bak (some of them are installed by packages and you'll probably want to keep them)
