Try zorin works fine, install zorin then uses the wrong graphics driver how can i ensure the same driver is used as with try zorin

[braak01]

When I install Zorin, my AMD (2010) graphics does not work. I cannot read the screen at all, it's a malee pattern. However, with try zorin it's all fine. Howe can I ensure that the same driver is used as with try zorin when I install from USB?

Thanks for your guidance.

When you install Zorin, do not connect to the net and do not check the box for "Install updates while installing."
Test if the above works. If it does, we will proceed to the next step to lock in your kernel.

Good morning,

I have tried the install in various ways, blocking wifi, no updates, anything I could think off. All, unfortunately, without success. The install does change the graphics driver that is useless as I can't see any text just garbage.

Is there anything else that can be done, like forcing the install not to update the graphics driver by changing the install script on USB?? I don't know if that's even an option ...

Thanks for your thoughts,

Rob

Here is how to access the grub recovery menu, to use the Root Prompt:

[HOW TO] enter Recovery Grub Menu (Advanced Options for Zorin)

To enter the Recovery Menu on Zorin OS if using Legacy (MBR) boot, you can hold or tap the Left Shift key at boot to be offered the Advanced Options for Zorin Grub menu. If using EFI Boot, then tap the esc key vigorously. Some users report that the tab key worked, instead. You might think that this is pretty straight-forward. However... Some BIOS are programmed to ignore a key being held down, as it is assumed to be pressed by accident or a stuck key. Cat on keyboard, coffee... The BIOS prog…

Once there, follow these steps to try the nomodeset grub parameter. That it works on the fallbak Try Zorin suggests it may be a modesetting issue on the bare metal install.

[HOW TO] add a grub parameter

There may be times that a user must add a specialized grub parameter in order to overcome an issue. The purpose of this guide is not to provide parameters, as that would be a case by case basis. It is to provide a guide on how to add one. To add a parameter, in a terminal (TTY, Recovery Prompt or Terminal Emulator) run: sudo nano /etc/default/grub Arrow key down to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" and place your parameter within the quotation tags. For example if you are adding th…

Thanks for your reply, however, I can't use any of the suggestions. The PC starts, I see the Zorin logo and name. The pc does not respond to anything or if it does shows a black screen until it stops and shows the strange pattern.
Any other suggestions? Like change the script in the usb stick to force to use the same graphics as the try me part ????
Thanks Rob

Are you tapping esc or tab at this point (EFI boot)?
Or holding Left Shift key if using Legacy (MBR) boot.

Sounds to me like this is a problem with a hybrid graphics setup.

Do you have the BIOS option to switch between discrete/dedicated (GPU rendered) graphics and hybrid (CPU graphics rendering)? Do you have this option in some windows-based GPU and CPU tweak tool? If so, try changing to the other one and reinstall Zorin and re-check for this problem.
