Stuck on boot screen when using Dynamic Graphics

General Help
#1

Hi,

I've been using zorin for a while now and its all worked fine. I have a Lenovo legion 5 pro, and when i use the dedicated graphics card (rtx 3070), everything works as expected. However, whenever i change to dynamic graphics in the lenovo boot manager and then attempt to boot zorin, i get stuck on the boot screen. I can provide more info if needed,
Thanks

Hi,

I may be daft, but when you say dynamic graphics do you mean switch to integrated video card?

#3

Well, yes but actually no. Dynamic graphics refers to the device dynamically using the dedicated or integrated graphics card depending on the task.

#4

Ah, okay. Not my expertise.

#5

However you could try upgrading the driver and/or the kernel and see if it helps. Let me know if you don't know how to do it.

Some instructions might be helpful, thanks

Driver for AMD/Intel;

sudo add-apt-repository ppa:oibaf/graphics-drivers
sudo apt update && sudo apt upgrade

If that doesn't work try with kernel upgrade to latest LTS;

sudo add-apt-repository ppa:tuxinvader/lts-mainline -y
sudo apt update && sudo apt upgrade
sudo apt-get install linux-generic-5.15

This has partially helped. After a reboot, my secondary monitor works but my laptop screen is blank and is not found under the display settings. I'm going to try the kernel upgrade now to see if that helps

I can't seem to get the last command to run while downloading the kernel upgrade, this is the error:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package linux-generic-5.15

Checked, they have moved from 5.15 to 5.16.2

sudo apt install linux-generic-5.16

#11

Hmm, after the kernel update my second monitor doesn't work at all, in any graphics mode, and my laptop monitor is called 'unknown display' in the display settings. Can i rollback the upgrade?

Tap esc or tab or left shift key at your motherboard splash screen to pull up the Advanced Options for Zorin in Grub menu; use the arrow keys to select which kernel to boot from.

To your issue;
Are you referring to using the Nvidia-Settings package?

Not to interrupt the troubleshooting - thought I’d mention, as an aside, that hybrid/dynamic graphics can cause issues in Ubuntu/Zorin. For example, inability to change brightness.
