You are talking of the LCD standby, right? You can disable this in the settings and keep the LCD switched on all the time (with backlight still switching off). This way you won't experience any of your issues.
Switch on and off hold will call s5l_clickwheel_init() and pmu_ldo_power_on(1) in firmware/target/arm/ipod/button-clickwheel.c Maybe you can find some time to play with those code snippets and find some interesting connections...

Should be fixed with r29764.

Hi guys. In my nano 2 gen 2 Gb white screen after turning off the backlight. Firmware 3.9 for Nano 2. Please suggest a solution. Not easy to Use with backlight on continuously.

Hi,
since r28159 there were several major changes to the nano 2G LCD driver implemented (sleep mode, massive perfomance increase, ...). It is very hard to debug such issues as there are several different iPod hardwares available...
Step 1) Please enter the iPod's Diagnostic Mode (first press and hold MENU + SELECT until the iPod resets, then -- during the Apple logo -- press and hold BACK + SELECT). In the Diag Mode select "Others", then "Status", then switch to the 2nd page. How are "LCD Detect0" and "LCD Detect1" set?
Step 2) Is it really the "backlight off" which hurts, or the "LCD sleep"? "LCD sleep" means that the LCD is really switched into a special state -- nothing will be visible on the display. You can turn the "LCD sleep" off in the settings menu (see the manual). This way the backlight will go off, but the LCD will not be put to sleep-mode.
Step 3) Did you test all releases (3.6, 3.7, 3.8 and 3.9)?
Step 4) Are you able to compile rockbox on your own? If you are able to compile it will be extremely helpful if you could track down the change which introduced this for you.

1) LCD Detect0:1
LCD Detect1:0
2) Is it really "LCD sleep", I had to disable the settings and it worked!
Thank you very much!!!
3) I tested at 3.8 and 3.9
4) Tell me how to correctly compile RoÑkbox, give a link where you can read, I myself could not understand.
Need to use SVN? Compile Rockbox in Win7 or only Linux?
Thank you again for your help!!! Sorry for my bad english((
Post Merge: August 23, 2011, 04:26:28 PMI found that the builds r28159 can not view settings Sleep (After Backlight Off). hence in the previous builds had no problems with my Nano2. Thank you again, because I can not live without Rokbox!
