[Nottingham] Last night's talk and ubuntu screen refresh rate

[Michael Erskine]

First, thanks to Danny for his talk on web development.

Next, for the bloke with the screen refresh rate problem in Ubuntu - this 
could either be a simple fix by putting the correct horizontal and vertical 
rates for your monitor in xorg.conf or it may be a symptom of using the 
proprietary nvidia driver with the twinview support on by default* 

Assuming the former problem, you'll need to edit xorg.conf and the quick way 
is to just use the technique outlined in 
http://ubuntuforums.org/showthread.php?t=435287 which is to run...

gksudo gedit /etc/X11/xorg.conf

...then edit the monitor section HorizSync and VertRefresh values to fit those 
in your monitor manual, e.g. : -

Section "Monitor"
        Identifier      "DELL M782"
        Option          "DPMS"
        HorizSync       30.0-80.0
        VertRefresh     56.0-75.0
EndSection

...then restart X (quick way is Ctrl-Alt-Backspace) and that may be it solved.

If not, then there's quite a lot of talk about the nvidia driver twinview 
feature which can also cause this problem (see 
http://ubuntuforums.org/showthread.php?t=435287)

Let us know if that fixes it - if it doesn't, I'm happy to pop round and try 
and fix it (free of charge of course).

Reagrds,
Michael Erskine.
