Re: [q] turn the screen on programmatically

So, after the marvellous ideas posted above I have a first, crude version. I don't know yet how much will suck your battery but I'm pretty excited and want to share it.

I know there are many things that should be improved like the commands that should not be in the loop because they are needed only once when the user locks the device (I tried hooking up to dbus-scripts lock event without success) but this is a first step. Also the backlight returns to 128 after unlocking and stays there whatever, but I haven't got around to that yet.

Script must be run as root. When you lock your device a dim time shows up just like on the N9 (with a huge pixelated font, but anyway)

Code:

while true

do

LOCK=$(dbus-send --system --type=method_call --dest="com.nokia.mce" --print-reply "/com/nokia/mce/request" com.nokia.mce.request.get_tklock_mode|awk -F "\"" '/g/ {print $2}')



if [ $LOCK == "locked" ]

then

    echo 0 > /sys/class/graphics/fb0/blank

    #uncomment this line for no backlight (darker image, less battery consumption)

    echo 2 > /sys/class/backlight/acx565akm/brightness

    d=`date '+%H:%M'`

    text2screen -t "$d" -s 10 -T 0xFFFFFF -B 0x000000 -x 50 -y 100

    sleep 2

else

   echo 128 > /sys/class/backlight/acx565akm/brightness

fi

done

Re: [q] turn the screen on programmatically

Nice start. You need to fix the LOCK= line in that code which I guess didn't copy and paste correctly. I tried using the dbus line to query lockstate from the wiki, but that always seems to return "unlocked" for me even when locked for both my N900s (could be something I've done, which I'll look into later). Anyway, I tried the middle part of the code over ssh and that's fine but the size of the time could be bigger.

Re: [q] turn the screen on programmatically

Yes, that's an error while copying from nano. Editing now. For the size change -s 10 to a number of your liking in the line starting with text2screen.
By the way after having the phone in my pocket for some time it started showing the time over the lockscreen, which is very nice because it shows the notifications too but I am trying to reproduce it some time now and I can't.

I modified the script to mimic more the N9 behaviour and unlock with double click. So far I've been able to configure xbindkeys to detect double taps and run a script, to run xbindkeys when locked and kill it when unlocked, but when I do double tap on the "idle" screen nothing happens (xbindkeys does not notice any taps, I can see the verbose console output afterwards) does this happen because the screen is painted with the framebuffer? should xbindkeys register something? Of course I have included the above line in the script.

Re: [q] turn the screen on programmatically

It seems that I overdid it and took care of things I shouldn't. This one works better, as it doesn't mess with default brightness settings

Code:

while true

do

LOCK=$(dbus-send --system --type=method_call --dest="com.nokia.mce" --print-reply "/com/nokia/mce/request" com.nokia.mce.request.get_tklock_mode|awk -F "\"" '/g/ {print $2}')

if [ $LOCK == "locked" ] 

then

    echo 0 > /sys/class/graphics/fb0/blank

    echo 2 > /sys/class/backlight/acx565akm/brightness

    d=`date '+%H:%M'`

    text2screen -t "$d" -s 10 -T 0xFFFFFF -B 0x000000 -x 50 -y 100 

    sleep 2

fi

done

I also tried to convert some bmp's to raw images for catting to fb0 with a bmp2raw I found somewhere on the net but it dumps the image scrambled. I suppose that the framebuffer doesn't have 800x480 resolution as the image doesn't fill up the screen.

That's all for now. Time to go to bed.

If you're not interested in the UI you can play a video in mplayer as well.

Code:

mplayer -vo fbdev videofile

Hehehe, a bit too much for a standby screen eh? :D

Yes I did that, but still xbindkeys does not read anything. Also the script eats too much cpu so I'll have to make it work with dbus-scripts. Maybe a sleep of a couple of seconds before issuing the commands would help

Edit:
In fact, yes... it does work.

I stripped the shell script to:

Code:

#!/bin/sh



LOCK=$(dbus-send --system --type=method_call --dest="com.nokia.mce" --print-reply "/com/nokia/mce/request" com.nokia.mce.request.get_tklock_mode|awk -F "\"" '/g/ {print $2}')



time=`date '+%I:%M'`

day=`date '+%m/%d/%y'`

till=3600



if [ $LOCK == "locked" ]

then

    echo "echo 0 > /sys/class/graphics/fb0/blank" | sudo gainroot >/dev/null

    #echo 2 > /sys/class/backlight/acx565akm/brightness

    text2screen -t "$time" -s 10 -T 0xFFFFFF -B 0x000000 -x 50 -y 100

    text2screen -t "$day" -s 10 -T 0xFFFFFF -B 0x000000 -x -600 -y 350

    till=30;

fi



if [ $2 == "QBW_DBUS_MONITOR"  -o $till -gt 100  ]

then

    id="/oh/no/more/qbw"$1

    dbus-send --session --type=method_call --dest=oh.no.more.qbw $id oh.no.more.qbw.set_param_uint32 string:'delayIndex' uint32:9 string:''

    dbus-send --session --type=method_call --dest=oh.no.more.qbw $id oh.no.more.qbw.set_param_uint32 string:'customIntervalSecs' uint32:$till string:''

    dbus-send --session --type=method_call --dest=oh.no.more.qbw $id oh.no.more.qbw.reset_rearm_timer

fi





return 0

Re: [q] turn the screen on programmatically

Another idea is to build images with imagemagick and have them displayed on the framebuffer with mplayer, so that icons, better fonts etc are possible. I'll look into it probably in the weekend
