The backlight on my Toshiba Gigabeat X series player remains switched off while the player is on. This bug is evident in all rockbox builds since r13102-070411.

In communication with people on IRC it appears this bug is only evident in X series players as all F series players have full functionality. Furthermore it was suspected the issue may be traced to a commit made by Karl Kurbjun. See below:

It should be noted that without a functioning backlight the player cannot be used. Making all of the latest builds for rockbox useless.

The backlight SOMETIMES turn off on the F series too. Its not all the time, and I can't seem to reproduce it. It just happens at random and it can be turned back on by getting to the LCD Brightness settings. Sometimes it will also randomly turn back on at button press. But usually I have to turn the unit off then back on.

Its been happening since one of the april builds - i'm sorry I don't know which one.
my rockbox.gigabeat file modified time is April 11th

For the X series, rebooting the player does noting, as does resetting the settings on startup, the backlight remains switched off either way. Tonight i will atempt to turn the brightness up by going into settings but it will probably be very difficult.

It helps if you are in a dark room with only a very little light to see the screen with the backlight off

I loaded the latest current build and managed to find my way to the back light settings section by writing down the number of button pushes and by vaguely following the line selector line across the screen and it seemed that no matter how much i changed them the back light remained off. Which i guess shows that their is 0 backlight functionality in Gigabeat X series players.
