[ltp] Using an external projector with t61 - mirror output

[Roman Haefeli]

hi martin

thanks a lot for sharing the solution. it addresses a problem, that has
been bugging me as well for a very long time (no 1024x768 provided) and
i had a hard time finding a solution.
now, your method definitely works, also for me, though i have a t61 (not
t61p) with a native resolution of 1680x1050. using the provided edid
file doesn't work here ( i get funky lsd-ish colors on one side of the
screen). therefore i would like to ask you about the way you created the
augmented edid file. i found the ubuntu package 'read-edid', which
provides 'get-edid' to obtain the binary data and 'parse-edid' to
convert it to human readable text. but when editing the text-file, how
can i create a binary file from that?

hints are very much appreciated.
