Hey everybody,
just coming here to report a little success. Due to its manpage, vald
only supports the Toshiba Libretto:
"The vald driver has only been tested on the Libretto L3."
Well, you can add "and on the Portege 3440."
All of the four keys work; F8 toggles the fan, F6/F7 the LCD brightness
and F5 switches LCD/CRT/both. In the manpage of the vald it says:
"BUGS vald has a problem with X11 when switching between
LCD and External Video output."
At least for the P3440 this is not true. Switching between LCD/CRT/both
will just work fine (tm) on this machine, even with X running.
