Kobo Start Menu 07

[jbaumann]

Ok, rebooted again, Kobo Glo with 3.15, Prep02d, executed both scripts again and all is well.

Went to Nickel, back to KSM, executed both scripts. All is well...

Cheers, Joe

A simple way to test: does the rotation issue also occur when not calling pngshow at all (i.e. not displaying an image at all).

Yes: problem is elsewhere
No: pngshow is culprit after all

Thank you for testing! The rotation issue is only on some models. Touch, Mini, Glo are not concerned.

Checked.
Two things here.
1. Both scripts do the same: Used directly from reboot -> flip screen, but using it after return from nickel -> ALL CORRECT.
2. I don't know if that meaning something but... when I use scripts before nickel I can see a white arrow over black screen, but if I use it after nickel I clearly can see a white arrow into a black circle over a grey screen.

boriar (or any H2O owner with the latest test version installed), could you please install the uploaded KoboRoot.tgz? This will introduce db_chk_integrity_nonanimation.sh in the same position as db_chk_integrity.sh is. Please test it.
Sorry for repeated inconvenience.

Checked in both situation (before and after nickel) and all perfect!

Sorry for repeated inconvenience.

I know what's the meaning of doing test. Don't worry I'm always happy to aid you. My H2O love your KSM. to you

This is a wonderful world indeed! (Since there is a cross posting: "both scripts" refer to those two scripts that display images.)

I see this on Touch and Glo too.
For those how do not see it themselves. I display a tiny png showing a white arrow on a black disc. The image covers only a small part of the screen. The remaining part is displayed black. But if nickel was started and exited, the remaining part is grey.

Thank you! This confirms that without showing an image (with pickel or pngshow), there is no flipping. I can only hope that Frostschutz will have some idea what is going on. In the worst case I have to skip the animation in those two (and some other) situations.[/QUOTE]

That's the spirit!

Hi Tshering,

bad news, I installed the d version and removed (backuped) the /mnt/onboard/.adds/kbmenu/ directory.

Now when I try to start the vlasovsoftlauncher it tells me "unsupportef version of launcher".

koreader still works.

Just wanted to report this.

Did you change anything else since the last time vlasovsoftlauncher did work? I just renamed my /mnt/onboard/.adds/kbmenu/ directory, and vlasovsoftlauncher is still supported.

Edit: Is it possible that you deleted /mnt/onboard/.adds/vlasovsoft/launcher, and that KSM tries to start an older version that is in /mnt/onboard/.kobo/vlasovsoft/launcher?

[tshering]

boriar,

Just to complete the information (my hope is that Frostschutz can make sense of the collected data), could you please

• copy set_pngshow_rotation_hack_enable.sh from the uploaded archive to .adds\kbmenu_user\scripts
• eject, disconnect, disable usb
• reboot (just to make sure showpng was not yet running in the test session)
• select user scripts > "set pngshow rotation hack enable.sh"
• call "chk db integrity.sh" (in case something unexpected is happening, like no animation or distorted screen, do not power off immediately, give the integrity check or the back up sufficient time to finish)

The purpose of "set pngshow rotation hack enable.sh" is to prevent pngshow from temporarily changing the rotation settings. If there is no rotation issue after calling "chk db integrity.sh", could you please also start and exit nickel and call "chk db integrity.sh" again?


You might already have a large collection of database back ups, and might consider deleting them. They are located in .adds\kbmenu_user\backup, and the names look like KR.sql_150818_1414.gz.
Thank you again for your help!

@tshering

Checked.
Are the hack temporal?
I checked both scripts in both situations (before and after nickel) and all go well, but if I reboot then need to apply rotation hack again. Now the arrow is in bottom right corner

Hey, you are quick! Yes this is only temporal. Frostschutz explained that pngshow changes temporarily the rotation, when it is run for the first time after reboot, in order to "detect rotation inversion behaviour of the device" (and to take countermeasures against it, I guess). When it does it, it creates a file /tmp/pngshow_rotation_hack_enable, so that it does not have to repeat this procedure each time pngshow is called again.
It seems that this temporal rotation change, and maybe the steps that follow in order to repair a detected rotation inversion behaviour, combined with whatever the Qt programs (I guess the screen driver used by them) does, result in the the rotation flipping.

set_pngshow_rotation_hack_enable.sh creates for test purposes the file /tmp/pngshow_rotation_hack_enable, in order to prevent pngshow to do the detection thing. Since the content of the /tmp folder does not survive a reboot, you have to apply it each time. As you supposed, this is only a temporary hack.

Let us wait what Frostschutz is saying. Maybe he could introduce a argument to skip the temporary rotation change. On could also try to figure out what the Qt screen driver is doing and whether one can change this, but I do not have any knowledge about that kind of stuff. I am not a programmer after all!

We prevented pngshow from checking so it does not know the rotation. This will in most cases not be very useful, but for the on-animation it is acceptable. Maybe showpng could read the rotation value without changing the rotation, in case it is called with the -skiptemporaryrotation argument.

That's what it does, when either /tmp/pngshow_rotation_hack_enable or /tmp/pngshow_rotation_hack_disable exists. If the wrong file exists pngshow will show everything upside-down.

I'll see if I can test this later, on my own H2O. I'm not using KSM myself, never installed it so far, but I'll put it on another SD card.

So I would have to create one of the two files depending on the hardware after boot. Right?

I appreciate that. This is the link to the version we are currently talking about. In order to exit from nickel back into KSM (if you need this for your testing) you would have to have kbmenupngs with its content in /mnt/onboard, and follow step one of "First time installation" in the first post before actually installing KSM. Alternatively, you could call /adds/kbmenu/fmonsh/exit_nickel.sh via telnet in order to return to KSM, though I never tried this myself. I think this is better, since you use KSM only temporarily.
