Bug Description

Binary package hint: laptop-mode-tools

When I boot my computer I see that laptop_mode tries to access something in /proc which doesn't exist:

/usr/sbin/laptop_mode: line 1555: /proc/acpi/video/VID/LCD/brightness: No such file or directory

Instead I found this file:

/proc/acpi/video/C136/C144$ cat brightness
levels: 100 51 30 37 44 51 58 65 72 79 86 93 100
current: 0

Can you please attach your /etc/laptop-mode/laptop-mode.conf and also the contents of /var/run/laptop-mode-tools/state-brightness-command if it exists?

echo [value]

I'm attaching the file to this comment. I found in the file that it is pointing to that file:

479: BRIGHTNESS_OUTPUT="/proc/acpi/video/VID/LCD/brightness"

Thanks. You edited laptop-mode.conf yourself, right? If you edit it, you're supposed to replace VID and LCD by your values C136 and C144 and for the echo <value> replace with an valid value, i.e.: echo 37
