A XF86 config file for Toshiba T2135CS machines.

# XF86Config for a Toshiba T2135CS Laptop.
#
# The monitor and device sections were computed by hand as directed by
# VideoModes.doc. The main problem with the Toshiba seems to be the fixed dot
# clock and refresh rates: you have to compute the vertical and horizontal
# resolutions (or frame sizes) to fit the fixed rates, and the standard
# resolutions (given in README.Config, for example) don't fit.

# The Toshiba User's Guide gives the horizontal sync rate as 31.5 kHz, but
# the XFree SVGA server computes it to be 31.56. Rather than diddle with
# horizontal frame size, I just used the server's computed value. See the next
# note for more about the 28.28 mHz dot clock frequency used in the mode line.
# The vertical resolution computed via VideoModes.doc is 537, but that
# requires a 56 Hz vertical refresh rate and the SVGA server rejects a monitor
# section having 60. This time I chose to recompute the vertical resolution to
# get the 60 Hz vertical refresh rate because I assumed it was 60 or nothing.
# The difference in horizontal sync rate seemed small enough to cover, but
# the difference in the vertical refresh rate seemed too large. I should point
# out, if it isn't already clear, that I know nothing about electronics of any
# kind.

# The values on the clocks line come from the SVGA server. VideoModes.doc
# doesn't say how to derive the dot clock frequency from the clocks line, so I
# just chose the most frequently occurring value. If you have trouble using
# this configuration, the first thing to do is comment out the clocks line and
# see what dot clock frequencies the server discovers. If the discovered
# frequencies are different (sorry I can't be more specific) from the ones
# given here, you'll probably have to go through and recompute everything.
