Zorin OS 15 Lite blank screen - power/screensaver settings?

I started trying Zorin OS 15 Lite from a ‘Live CD’ (actually from a ‘Live USB’) but when I walk away for a few minutes, I come back to it being stuck in a blank screen. I tried tinkering around with the power settings to no avail. Anybody know how to leave Zorin OS 15 Lite on indefinititely without it sleeping/hibernating or the monitor stop displaying? (I can worry about Super+L to lockscreen manually later when and if I’m not working with a ‘Live CD’).

As a secondary question, if one ends up in a blank screen on the Zorin OS 15 Lite trial ‘Live CD’, what are the commands needed from CNTL+ALT+F1 or CNTL+ALT+F2 to get from the blank screen back to the desktop?

I’m seeing if Zorin OS 15 Lite is a suitable fit for me and any help would be appreciated.

Zabadabadoo had suggested on here a while back an app called Caffeine which prevents LockScreen or Screensaver from shutting things down.

As to your question: The Well Known “XFCE will not wake from sleep or suspend” bug has a great many of porposed solutions and it really depends on each individual which actually works. We can go over that if Caffeine app will not work in your situation.

FYI. This is my post (mentioned by @Aravisian) where I suggesting Caffeine as possible screensaver stopper:

Note, I have not used Caffeine on Zorin, only on that other OS.


Thanks! Caffeine worked excellent. I thought the patient was comatose because I tried telling it


to no avail. I disabled the screensaver & lockscreen, set display power management to “never” as well as suspend/hibernate when inactive to “never”.
I installed caffeine and you simply activate it from the dash & system tray. I opened gedit & can toggle that text editor to & from fullscreen by F11, fullscreen invoking caffeinate.

I vaguely remember reading about the bug while troubleshooting. That really is ashame because the bug defeats the whole purpose of the “Live CD”; trying to turn people on to Zorin OS 15 Lite. A good many people would throw their arms in the air with it.

Ironic caffeination was the lifesaver for the coma in this particular case, as for me it makes me a raw bag of nerves as much as I like it, so I avoid it all together!


@Joe-S. Can you please tell us here which Caffeine app (assume you installed from “Software”) worked for you.
As there are more than 1 instances of Caffeine listed in Software, your answer may help point others to effective one.

I simply:

sudo apt-get update
sudo apt-get install caffeine

I just looked at Synaptic Package Manager and see there is “caffeine” then there’s “caffeine-plus”. It’s the first one, plain “caffeine” that worked here.
