Screen Switches Off After A Short Time ?
« on: July 20, 2006, 12:19:05 pm »
I have installed recently GPE on a dual Opie / GPE setup.

All works more or less great  - however my unit switches the backlight off after a short while - and I am unable to bring it back on. ( The LCD is on, as it can be seen under a strong lamp)

Is there a fix for this?

Do you have an ssh connection?

Do you have bl installed?

What does /etc/ipaq-sleep.conf show?

That's the problem w/ dual Opie+GPE images. If you are in Opie, GPEs powersafe deamon "ipaq-sleep" will shut down the display since the X11 session is idle. If you are in GPE, Opies powersafe functions will do the same.

A work-around would be to disable screen blanking in both GPE and Opie.

It is one of the annyoing things stopping me to release combined images for download (there are some more however, like non-working SDL (3D rendering) in one of the two GUIs)
