[mythtv-users] Stuck at low res using cx18 based capture card AND nvidia binary? Read this:

[Larry J on his Dell LT]

Does your system stubbornly  boot into low res.  say 640x480 or 800x600 
and even though your /etc/X11/xorg.conf shows that the "nvidia" drivers 
are used?  If so, attempt to see if one of your capture/tuner/encoder 
cards uses the Conexant cx18x chip.  Try   dmesg | grep cx18 and see if 
you get a hit. The Hauppague HVR-1600 uses this chip. If  cx18 shows 
up,  you may be experiencing a tricky nvidia binary incompatibility. 
Fortunately there is a work around.

(Other symptoms:  sudo nvidia-settings says "you appear to not be using 
nvidia..." even though the /etc/X11/xorg.conf file clearly specifies 
"nvidia" drivers.  Also when you run sudo nvidia-xconfig, it outputs a 
valid /etc/X11/xorg.conf file but after rebooting, you are still stuck 
at low res.)

Your symptoms?    Read this: (Thanks  76GTA and others)
