Hello,
I just installed Primo 2.4 on a GPS running winCE 6.0 (most likely a chinese one, branded Klipad GPS4328). It runs OK but I noticed the brightness slider from inside the app doesn't do anything (no dimming of the backlight).
I googled a bit and found a couple of topics about the backlight not working, tried pretty much all the solutions proposed in the threads I found but still no luck... The best I could get is Primo changing at startup the timeout settings for the backlight to dim to a lower brightness after 10s or so of inactivity. Looking at the PNA registry, I found the backlight entries are the following (in the folder HKEY_LOCAL_MACHINE / DRIVERS / BuiltIn / BackLight):
Brightness - 50
CurrentDx - 1
DefaultDx- 19
Dll - columbus_backlight.dll
Duty - 9
FriendyName - Backlight Driver
IClass - {A32942B7-920C-486b-B0E6-92A702A99B35}
Index - 1
Order - 4
Period - 19
Prefix - BKL
The settings I put in system.ini of primo to get the behavior described above are the following (I tried some other values as well for "backlight_events" or "backlight_methods" which were not giving any result; I'm not quiet sure what those parameters do... :
[power]
backlight_day="0"
backlight_events="1"
backlight_key_bright_ac1="ACBrightness"
backlight_key_bright_ba1="Brightness"
backlight_key_on_ac="ExtOnOff"
backlight_key_on_ba="OnOff"
backlight_key_ontap_ac="ACBacklightOnTap"
backlight_key_ontap_ba="BacklightOnTap"

skip_resume_process="1"
skip_resume_process_all="1"
skip_suspend_process="1"
skip_suspend_process_all="1"
treat_charging_as_ac_line="1"
Any help would be greatly appreciated.
Thanks,
