Ubuntu and screen resolution and MIT

[Jerry Feldman]

Fedora is also deprecating the xorg.conf. In my case it is a laptop with
an ATI Radeon chip and (about 5 years old). Apparently the Ubuntu
Display Preferences panel does update the xorg.conf file, but
fortunately renames the old one by date/time. Unfortuantely it is a
cut-throat industry, and none of the chip makers want to open source
their drivers out of fear that it will expose their chips.  I have an
Nvidia system at home. It also seems that these guys generally come out
with incompatible chips every few months.
