--- Comment #39 from Geraud <geraud.bonhomme63 at laposte.net> ---
Hello,

Just one question...as explained I don't know if I can help myself much
more...but I guess I can share the issue on this forum to investigate deeper
with the help of people who know how libreelec works and what can be tried:

https://forum.libreelec.tv/thread/12380-le-8-2-5-with-uhd-630-coffee-lake-gemini-lake-support-and-luks/?pageNo=12

Hence, if somebody can first confirm me that when I run the command line:
at /sys/module/i915/parameters/enable_fbc and get the result "1" it means that
fbc is activated or not.

Using this information I can then confirm that it is linked to fbc or not.

If not it means that libreele is not taking into account the drivers options I
created...so I can have a look on how I can force it to use it.

If not then I can log a new bug report I guess...but at least it will be clear
if my issue can be related to this bug or not.
