OMG, is this thing a MESS!!!!  I had it working for literally 5 
minutes.  When I got that message about running in low-graphics mode, I 
clicked Configure, then chose the ATI Radeon fglrx open source driver, 
then rebooted.  It came up fine, ran mythfrontend, and when I went into 
LiveTV, both Analog and Digital played fine (no sound, but that's 
next!).  The video looked great.

All fixed?  Nope.  Here comes the mess.  Ubuntu put up some alert about 
having drivers that aren't supported by ubuntu and wanted me to download 
something.  Unfortunately, I did and told it to overwrite a few files 
that it asked me about ("over write <xxx> with the version that the 
package maintainers use" type of thing).  Now when it comes up after a 
reboot, I get a blank screen

I looked at /var/log/messages, and I get a message stating the following:

Here's the "Device" section of my xorg.conf:

Section "Device"
        Identifier      "Configured Video Device"
        Boardname       "ATI Radeon (fglrx)"
        Busid           "PCI:1:5:0"
        Driver          "fglrx"
        Screen  0
        Vendorname      "ATI"
EndSection


All seems to look OK and I didn't see any errors in 
/var/log/Xorg.0.log.  How can I go about backing out all of the video 
drivers and starting from scratch?

Thanks,
Harry
