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!
