Hi Community,
I installed Zorin Core 17.2 a couple of days ago and I am enjoying the experience. However, when shutting/powering down (via menu and terminal) the screen eventually goes blank (black) but the laptop is still powered on (fans still running). Similarly, when rebooting/restarting, the process seems to complete but then ends up with the screen going blank (black) and the laptop still powered on. I have let it remain in this state for as long as 20 mins, but have to physically power the laptop off via the power button. Can anyone advise a fix?
I have read similar posts on the forum. I have followed steps with terminal commands etc. but to no avail.
Zorin is my first Linux experience. I have come over as a long time Windows user. Grateful for your patience with my zero knowledgebase. If any terminal command suggestions - grateful for step-by-step instructions. Thanking you all in advance.
Yeah, it sounds like your system is hanging on shutdown, which is strange.
(1) The next time that you start the computer, spam press the key your computer uses to enter the bios, could be the F2 key, or the DEL key.
Once you are into the BIOS, look for Secure Boot and Fast Boot, and make sure that you disable them both, then save and exit the BIOS.
(2) When you reach the login screen, please click on name, don't put in your password yet. When you click on your name, a cog wheel, will appear.
Click the cog wheel, and select Zorin OS Desktop on Xorg/X11. You don't want to use Wayland, its garbage right now IMO, not ready for prime time, but X11/Xorg is decent.
Hopefully now, your system will function properly. If you are still having issues after implementing these steps, you can come back here and let us know.
This sounds like an ACPI issue.
ACPI = Advanced Configuration Power Interface.
You might try a grub parameter to prevent ACPI errors and see if that helps your issue.
You can try acpi=force or acpi=off.
After setting a grub parameter, remember that you must run
sudo update-grub
for the changes to take effect.
How to add a parameter:
The above guide uses nomodeset as a parameter. You will be using acpi=off, not nomodeset.
I've followed both your suggestions, but cannot seem to reach a solution where the laptop successfully powers off & restarts. I couldn't think of how best to relay the permutations of steps I've taken, so I've tried to summarise by way of a table. The steps I took, in turn:
BIOS
I couldn't find any reference to 'secure boot' or 'fast boot' in the BIOS menu. The only thing close to it was:
2.Desktop setting & grub parameter
As I try to illustrate in the table below, each permutation of changing the display setting and grub parameter resulted in a different outcome. Broadly, when acpi is set to "acpi=off", the configuration and settings of the laptop go haywire e.g. flashing wireless light on the laptop chassis; screen resolution changing etc. Additionally, when desktop setting is changed between X11 & Zorin Desktop (I assume this is Wayland?), the name of the graphics card changes slightly.
The permutations of actions I've taken and the ability to restart/power-off is as follows (green = successful; red = black/blank screen, laptop still running):
This will read the contents of kernel logs and save it to a file in your desktop, named "output.txt". Hopefully, it might contain some details as to what's going on with the shutdown sequence.
It's probably too large to just copy and paste it here, so you can use something like https://pastebin.com/ to upload and share it.
