Try echo 1, echo 0, etc ... It may do something
Thanks for the suggestion. It doesn't work, though I think it's trying to
do something. The code for the "disp" file checks a capabilities bitmask in
which I think the DISPLAYSWITCH bit is set, and writes call a method called
SDSP, which eventually seems to do an I/O byte write (I think). I'm well
out of my depth here so I'm going to move on to the next problem, but I'm
willing to try out any suggestions that people have.
It may be like http://acpi4asus.sourceforge.net/README
To switch the displays, echo values from 0 to 15 to
/sys/devices/platform/asus-laptop/display. The significance of those values
is as follows:
+-------+-----+-----+-----+-----+-----+
| Bin | Val | DVI | TV | CRT | LCD |
+-------+-----+-----+-----+-----+-----+
+ 0000 + 0 + + + + +
+-------+-----+-----+-----+-----+-----+

Yes, I tried all these values (and a few hundred thousand more...) with
no luck. Thanks for the suggestion.
Phil.
