[Bug 1423825] [NEW] Ubuntu Touch dims screen backlight with Bluetooth keyboard in use

 

Public bug reported:

I have latest Ubuntu Touch 15.04 (r101) installed on Nexus 7 Wifi
tablet.

When I have Bluetooth keyboard in use in, say, terminal application -
the system dims the screen after a short period of time as if system is
not in use. All this time I do use the system - just only via keyboard
input.

I believe this is the same when wired keyboard is plugged in via OTG
cable.

In summary: it seems like Ubuntu Touch does not currently register
hardware keyboard input as user interaction for the purpose of keeping
the high screen brightness and just dims the screen backlight as if
there is no user entry/interaction with the device, even when hardware
attached keyboard is used all the time.

The somehow ugly workaround is to open terminal window and key in: `$
powerd-cli display on bright` and then keep this terminal tab open all
the time while you use hardware attached keyboard. This will keep the
screen at full bright all the time.

  the system dims the screen after a short period of time as if system is
- not in use. If I touch screen at this moment - the screen brightness
- gets increased again. But then I keep working on keyboard only again and
- the screen dims again after a short while.
