In 17.04 I could suspend\hibernate from the power off menu button.  I can't find how to do this in Ubuntu 17.10 GNOME Shell.

Windows 8 is set to sleep after 30 mins, and it used to work, but recently it's started refusing to sleep. (I can still manually ask it to go to sleep without any issue.)    I was having issues a while ago, but it was with my network adapter. That's since been disabled, so it's definitely not that:    I've checked to see what devices are able to wake up my machine, but it only appears to be my mouse:    Which is odd, because I haven't recently changed my mouse, and more confusing still: The monitor does go to sleep just fine. If it was actually the mouse keeping my system awake, I'm pretty sure the monitor wouldn't go to sleep.  I've checked my Wake Timers, and nothing:    I've also checked my existing requests...  UPDATE: I found something. What to do with it, I don't know...    Note: Even when /requests says that there's "NONE" under every category, my machine still won't sleep(!).    In short: How can I tell what's preventing my computer from Sleeping?    UPDATE: Ok, so I now have a few more pieces of the puzzle. I came back to my computer and it was ASLEEP! Lawks! It seems that the only times it doesn't sleep is if VLC Player is open, even if a video isn't actually playing.  UPDATE UPDATE: Ok, so it won't sleep sometimes when VLC Player ISN'T running, either. Bah!

I upgrade my Ubuntu to 11.10. I restarted and it worked perfectly until now when I restarted again and it is now in text mode after I login. Can somebody please provided some suggestions on what I should do? I do not understand what happened.    I tried restarting lightdm but it is already running.

I know you can automatically Sleep and Hibernate your computer with a timer. But these affect running programs and stop downloads ... so I was wondering if there is a way to automatically Lock your computer with a timer?

First and foremost I want to know how long my laptop (unix, apple, OSX 10.9 mavericks) has been 'awake' (i.e. how long its been open, or since it last 'slept').  I' also be interested in how long since the last restart, and time since the last shutdown (if those two things can be differentiated).  I've tried the who and w commands, which seem to show me time for the whole system, and for individual processes (terminals?) since the system last restarted.  Is there a way to tell how long the system has been awake, explicitly? Does the reported process times include sleep-time (i.e. when my laptop is closed)? Is there a way to distinguish between restart and shutdown?

In Ubuntu 11.04, Ctrl-Alt-Del gives me a menu with shutdown, hibernate, suspend and restart, but no logout. Is there a key combination to logout of Ubuntu? Is there a way to provide one?

I have heard a lot about Ubuntu-Tweak and how it is great for power users, but I don't know how to install it.  How do I do that?

Is there a way to run a script when a computer "wakes up" (from sleeping)? I know it can be done on startup, obviously, but the issue in this case is that the backlight of my laptop seems to reset every time it wakes up from sleep, and I'd ideally like to have a script take care of turning it down to a reasonable level instead of having to type it in manually every time.

My keyboard doesn't have power-related keys. I would like to enter the hybrid sleep using the keyboard and only with a minimum of keystrokes.  If there is none, how do I bind a hotkey to it?

I want to be able to 'put the display to sleep' on one of my two monitors when it isn't needed, so it doesn't distract me or use unnecessary power.  Ideally, the display would be asleep, but the OS would remain in dual-monitor mode, so I could still have a variety of windows open in the sleeping monitor's display space, which would mean I wouldn't have to keep switching between single- and dual-monitor modes.  That said, I'd also consider a solution that made it easy to toggle between single- and dual-monitor modes without navigating several system menus.

When I wake the laptop from the sleep I need to get the VPN state as I left it (turned on). Can't find the setting of autoconnect in VPN settings... Need some easy way to ask the system to autoconnect the VPN when the internet is available.  Edit based on comments:  Ubuntu 18.04 has no option to Always connect to VPN when using using this connection.

I have a laptop back home with Windows Vista installed.  I want my computer to fall asleep automatically at 01:30 AM and wake up at 06:30 AM.  I have tried a lot, but making a .bat file which makes it fall asleep needs to be manually activated. How can I do it automatically?
