I have my Matrix orbital 212 (LCD) working (LCDproc shows stats etc), BUT,
there is a problem with the backlight.
Sometimes the backlight stays on a shows the screens. Sometimes, it starts
to blink the backlight every few seconds making it hard to read the screen.
Any ideas why the backlight is blinking? My config is below.
Thanks,
M
