My HP laptop tends to boot with a dim screen. I can fix this with echo 10 > /sys/devices/virtual/backlight/acpi_video0/brightness
which I run from /etc/rc,local. It works well with all kernels up to 2.6.37. With 2.6.38 there is usually no /sys/devices/virtual/backlight... so the above command can't work. What is really odd is that if I first boot with a 2.6.37 kernel and then reboot with a 2.6.38 version, everything works correctly. The file I need to modify is there and there is full brightness. Is this perhaps something to do with udev? I've found ubuntu bug reports describing somewhat similar problems but mostly with backlight being too bright rather than too dim. I would make a bug report if I knew which package was at fault. Can anyone shed any light (literally)? It's an annoyance rather than a major problem but I've been trying to figure it out for at least two weeks wthout success, Anthony -- Anthony Campbell - a...@acampbell.org.uk Microsoft-free zone - Using Debian GNU/Linux http://www.acampbell.org.uk - sample my ebooks at http://www.smashwords.com/profile/view/acampbell -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
