STM32MP157F-DK2 Screen suspend issue

[BVino.1]

Than try to use this board with Debian Linux + Xorg happened strange behaviour: after one hour screen disabled forever.

No any warnings or errors in dmesg.

This issue reproduce on kernel from STLinux (5.15.67).

Also these steps make same behaviour:

echo 1 > /sys/class/graphics/fb0/blank
echo 0 > /sys/class/graphics/fb0/blank

Hello @BVino.1​ ,

It let me think about something that I have already seen with fbdev use.

Can you check the following patch to see if it changes something for you ?

Kind regards,

Erwan.
