Public bug reported:
Just upgraded from 9.10 to 10.04 (clean install).
It seems the new kernel modesetting does not recognize my LG 42'' TV connected
with an RGB cable.
The monitor is detected as Goldstar Company LTD 42''
Should mention that same TV and screen worked perfectly with 9.10.
Here is a relevant piece of Xorg.log
