Display bug when switching output from hdmi to dvi or dvi to hdmi

1st Official Post

    Summary :

    When I used OpenElec with an older version, I was able to switch from DVI to HDMI and HDMI to DVI, without any display issue.

    Now, I am still able to switch, but the display becomes horrible. I have to apply a work around to make it usable.

    If initial openelec version is needed please let me know. I would need to restore it to have its version.

    Full hardware specs (GPU is most important) :

    ============================================

    Giada Cube N3 HDMI ION Atom 33

    CPU

    - Intel Atom N330 - 1.6GHz

    - Chipset NVIDIA ION Graphics

    Connecteurs :

    - USB2.0 : x 5

    - DVI : x 1

    - VGA : Adaptateur DVI / VGA

    - HDMI : x 1

    - E-SATA : x 1

    - Lecteur de cartes : 3 en 1

    - Audio In/Out : x 1

    - 100/1000M Lan : x 1


    The LibreELEC version you are running :

    =================================

    8.2.2

    In most cases a full debuglog

    ========================

    Please Find it attached : kodi.log

    Tell us the complete steps how to face the issue, so we can try to reproduce

    ==============================================================

    Initial state : display on DVI

    Go to System/Settings/Display

    You will get output : BeforeSwitching.jpg

    Click on "Monitor" to switch (switch to hdmi then switch back to dvi )

    It work, but you will get output : AfterSwitching.jpg (horrible, can't read most of label)

    WorkAround :

    ===========

    Go to Interface / Settings / Skin

    Switch to another skin (confluence in the example)

    Display is fixed : AfterChangingSkin.jpg

    I can then change back to the intial skin, and it is still ok

    Maybe if skin was automatically reinitialized after switching from an output to another it would work?

    LE 8.2 has newer drivers than OE, but with Intel newer doesn't necessarily mean better. Have a play with a current Milhouse release to see if things resolve under a newer (again) kernel and drivers.

    I did try with "LibreELEC-Generic.x86_64-9.0-Milhouse-20171228214630". It's worst, I get a black screen with a white square on top right. It is then Impossible to apply the work around described previously

    Attached the output after changing output : AfterSwitch_Milhouse-20171228214630.jpg

    The only way to get kodi working again is to restart it : systemctl restart kodi

    Unfortunately, I don't know how to launch such a command from kodi ( I did try

    xbmc.executebuiltin('System.Exec(systemctl restart kodi)') but it does not work).

    Conclusion : I revert back to 8.2. I will create another topic to enhance scripting of switching output + applying workaround
