This ability is actually planned for ASUI. I just need to figure out the best way to handle it. Probably unmap ASUI and open its blank window to grab all keys. Use a simple command language in asui-settings to map keys to dbus calls, ignore them or pass them through. The screen automatically comes on when a key is pressed so I'll probably have a configure the delay before turning it back off. That way it would only remain on for a few seconds instead of for your entire dim/blank timeout.

Thoughts?

Isn't the dim/blank timeout done in milliseconds?

Why not just set it at 1?

Maybe it won't even be noticeable.

What if you want to see the screen briefly while pressing the keys? Duration is not a problem since the user would be able to set it.

Is there any possible trick around this?
I wrote a hack, but unfortunately it doesn't work correctly: Sometimes, when locking, this program picks up spurious input events making the program think the zoom keys have been pressed, even when they haven't.

The idea behind this program (was supposed to be) is simple: If the zoom in/out keys are pressed are pressed while the tablet is locked and the display is dimmed/off, it will run /home/user/xmmskey and pass which zoom key was pressed by passing it as argv[1] (in a script, you can check if $1 = "in") and you could run xmmsctrl (available from free's debfarm repository) from this script.

If a resident Maemo 4 programmer (I don't know what I'm doing!) knows where I've messed up, I'll fix it, but it seems like auouymous is working on something anyway.

Okay. So perhaps just have that customizable on the user's side then?

Your KP_PATH only works on n800. Need to detect device type and change KP_PATH if you want it to also work on n810.

The key handling code looks correct, ASUI uses similar code to read the power button but not glib, maybe a problem with glib. Have you tried
Code:
printf("event: time=%f, type=%u, code=%u, value=%d\n", (float)ev.time.tv_sec + (float)ev.time.tv_usec / 1000000.0, ev.type, ev.code, ev.value);
after the ev.value condition? You can then see the time each event occured and its parameters.

Ooh! Hey!

I finally got around to using the built in Email with my Gmail POP account after all these years.

I love how I can now receive LED notifications.

Is there any hack to have it scan for new messages every minute though?

The lowest setting is only at every 5 minutes.

not sure but you could try setting the 'update interval' with gconf-editor. (apps > modest)

Isn't it a bit of abuse to scan every minute?
If it comes by email, sure it can wait 5 minutes, can't it?

I only ask because LED notification for Dial Central is still broke with it's latest build.

This would be a simple alternative instead.
