Getting 1280x1024 to work on my dual head system
After a lot of trial and error I have finally got an almost perfect dual
head configuration set up.
My main monitor is at 1920x1080 my secondary monitor is currently maxed
According to the monitor specs my secondary monitor is capable of
1280x1024 but the Gnome Monitor preferences doesn't allow it.
I tried adding a modeline in xorg.conf to specify the 1280x1024
resolution which I copied from elsewhere. It half worked in the sense
that it looked like the the new resolution was recognised, but since I
didn't really understand all the parameters, the vertical stretching was
all wrong (ie it was putting the bottom of the screen edge of the bottom
of the monitor).
Can someone help me construct a modeline - I am not really sure what all
the parameters mean
The Monitor Manual gives the following (as one of two separate options)
mode SXVGA 1280 x 1024
Horizontal Frequency 79.976Khz
Vertical Frequency 75.025Hz
Dot Clock 135.000MHz
but how these map onto the modeline parameters I have no idea
