I'm a new Ubuntu 13.10 user. Closing the lid of my laptop does not result in the computer entering suspend mode, meaning each time I close my lid without manually suspending the computer the battery dies.
The proper settings are set in Power Management -- suspend the laptop on lid close for both AC and DC, but these do not have an effect on actual behavior.
It looks like this is a common problem for many users as far back as Ubuntu 11 -- the only solution I could find is the below. However, as a new linux user I'm not aware of how to actually execute the instructions. If someone could provide additional detail that would be tremendously helpful.
Thanks in advance.
/etc/acpi/events/lidbtn triggers /etc/acpi/lid.sh which triggers /etc/acpi/local/lid.sh.post at the end of the script. /etc/acpi/local/* allows you to add your own config (e.g. required for wmii).
generate /etc/acpi/local/lid.sh.post make it executable and add:
#!/bin/bash grep -q closed /proc/acpi/button/lid/*/state if [ $? = 0 ] then /usr/sbin/pm-suspend fi
wmii will now go to suspend mode when closing the lid. It'll automatically wake up when opening the lid.
