.35 shows the same issue (although I didn't recompile my perf binary). I
don't know if this is a regression - it might always have been there...

It certainly is weird. When the machine reboots I notice that the
backlight is not at its normal level as if something was dimming the

when powersaving these days?). As the only backlight driver on my system
is in eeepc-laptop that's why I removed it.
