The screen does not appear when waking from sleep mode.

This is my first time using Zorin OS. My current version is 17.3 Education. My laptop model is HP Victus 15FA1xxx. It has an i5 13500H processor, 16GB RAM, and an Nvidia RTX4050 graphics card. When my laptop goes to sleep and wakes up, the screen does not turn on. I've tried everything, but I can't seem to fix it. If I can't resolve this issue, I'll have to switch back to Windows. This is my only issue; otherwise, I'm very satisfied with Zorin OS.

Welcome to the Forum!

Because You have a Nvidia Card: oes Your system run in Wayland or X11? You can check that in Settings>About. When it runs in Wayland, I would suggest to switch to X11/Xorg. To do that, go to the Login Screen (not the Lock Screen). Simply reboot for that. On the Login Screen, click on Your Profile so that the Password Field appears. When it is appeared, You should see a Gear Icon in the bottom right Corner. Click on it and choose the Option ''Zorin Desktop on Xorg'' and then log in and try if it works.

Another Thing: what Driver do You use?

And how are the Settings in Settings>Power for the Display and in Settings>Privacy>Display set up? I mean these:

EDIT: Forget something: Are Secure Boot and Fast Boot in BIOS disabled? And if Windows should still be installed, ist Fast Start-Up in Windows disabled?

This seems to happen often on this laptops. The only solution I found for HP Victus
was adding a grub parameter to /etc/default/grub:

You could try it and when it doesn't work delete the added parameter.

Open the terminal, enter

"sudo nano /etc/default/grub/"

Navigate with the key arrows to line

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

and change it into

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_idle.max_cstate=4"

If you have more parameters than quiet splash there, please keep them.

Then press CTRL+o to save, Enter to say yes and then CTRL+x to exit.

Then run

"sudo update-grub"

and reboot.

You could also try to go into suspend manually by pressing the button in start menu and see if that helps.

Hopefully Forpli's post can help you. I've been on Linux for 15 years, no matter what distro used, I never could use sleep without causing the exact issue you describe.

I prevent my computer from going to sleep, & I disabled the lid switch in the OS. Instead, I use XScreenSavers APP, to run a screensaver instead.
