Comment # 25 on bug 1180591 from
Same thing for me.
one of the differences I noticed, in the initial startup, there is no mention
of backlighting (dmesg)
on the other hand, after a standby mode, the following appears:
"video LNXVIDEO:00: Restoring backlight state"
I don't know if this can help you.
Is there a way to start this command after the initial boot to test if it
changes anything?
