Yes, that's correct. Note that only root can run the shutdown command by default. So, if you have not done any tweaking with the permission of running the command just put the cron entry in the root user's crontab or add the entry in /etc/crontab mentioning the user as root. EDIT (Regarding Anacron): Absolutely bad idea. generally anacron is used while you ...

I found the problem. I've been messing with the files in /etc/pam.d in order to connect the xubuntu system to a domain and I had overwritten the information in /etc/pam.d/common-session. Once I put the default information back in, it allowed me to shut down through the GUI.

I experienced a similar problem, and I believe the issue was a configuration issue with lightdm. Unfortunately, uninstalling lightdm does not remove all the configuration files. I recommend trying to remove all the lightdm.conf files, and any file with that in its name, and then reinstalling lightdm What I'm suggesting is risky! If lightdm get's messed ...

Runlevel 0 corresponds to shutdown, and Runlevel 6 corresponds to reboot. The /etc/rc[0-6].d/ directories contain scripts that are executed when a particular runlevel is initiated.

It only works for me if I short circuit the /etc/acpi/powerbtn.sh completly by inserting shutdown -h now in the very beginning. It's still a hack but now it works every time.

Like, Chih Ho mentioned this is a bug. I'd like to offer a work-arounds here. It may be useful for others in future as well, and I had a lot of fun while pondering this question, so might as well post this "solution".

I'm researching this problem on an Intel NUC DE3815TYKE/H with Lubuntu 14.04 installed on the internal 4GB eMMC. I've already run the software updater.My current theory is that, as one cogent forum user advised me to forgo a swap partition (due to installing on flash-based media,) the system is looking for (& not finding) that swap-space during the ...

If all goes well, you ...

As you have already discovered, some of what you appear to need to make Ubuntu work correctly on that computer hasn't been produced yet. In time, I'm sure it will be supported. Yours is not the first time I've heard of very new hardware not being supported. About the only cases in which you purchase state-of-the-art computers without any linux support ...
