I cant boot my Linux 18 OS

Hardware Support
1

Hi, I'm having a problem with my operating system that I just installed. I have a problem where every time I turn off the computer and turn it on again, the only way to turn on my computer is by using Zorin OS's Recovery mode and then booting normally.

I can't boot the computer without using recovery mode. Also, every time I turn on my computer, the resolution decreases to 1024x768, while normally it should be 1920x1080.

I suppose the problem is with the graphic drivers. Mainly because I try to play some games, like "Sober," and it always says "cannot support graphics device," even if I do everything. And even Steam games, like I tried with "War Thunder," seem to have an incompatibility with my video drivers, which is incorrect.

Even if I try using sudo apt update or sudo upgrade, I can't get my computer to boot correctly or the apps (like games) to work like it should.

I agree that sounds like graphics.

What graphics card and driver are you currently using?

sudo lshw -C video

The results are these, and about the driver, i dont know espefically

Welcome to the Forum!

Are Secure Boot and Fast Boot in BIOS disabled?
If Windows is installed: Is Fast start-Up in Windows disabled?
Is Your BIOS in UEFI or Legacy Mode?
What Tool did You use to create the bootable USB Stick?
For Steam: Is Steam installed as Flatpak or .deb Version?
You could try it with Boot Repair. For this Start Zorin on the USB Stick in Live Mode (Try Zorin), search there for ''Boot Repair'' and let it run.

This is a card which was released around the time that AMD switched from Radeon, to AMDGPU.
Since you are seeing a KMS fallback and no driver loaded, it is a strong bet that the kernel, during init, hangs at trying to determine which driver to load.

What is your terminal output for

ls /lib/firmware/amdgpu | grep -i wani

6

There is no output

Hi, ponce; yes, i checked even before installing that Fast boot or secure boot was disabled, for cases like this, and no i cleaned my Hard Drive completely for Zorin or OS, and my BIOS is in UEFI - and i used an Pendrive about 4 gb in storage - which if thats the problem, please say for me - and steam i used the .deb version.

And, sure, i will try the boot repair

Can you also check:

lsmod | grep amdgpu

ls /dev/dri/

It looks like you should use AMDGPU (In the kernel, do not install from AMD, as they do not support this card any longer) and disable Radeon.

Using the parameters radeon.si_support=0 amdgpu.si_support=1
Should work.

No, this isn't a Problem. But what Tool did You use to create the bootable USB Stick? Because Your BIOS is in UEFI, it would be good when the Bootstick was created with the GPT Partition Sheme.

10

I used the "Rufus" app and followed the normal step-by-step instructions; however, I used MBT instead of GPT because, according to the tutorial I saw, MBT was for older hardware like mine

11

I used the first command and no outcome. And i used the second and it says

by-path card0

And i dont know exactly where to put that parameter exactly in GRUB

12

Ok, this shows that you have No Graphics drivers loaded.

Have you tried adding the parameter I listed in post number 8?

13

In which line should i add the parameter you listed, then i could try it

14

In this line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

Make it look exactly like:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash amdgpu.si_support=1 radeon.si_support=0

There is one space between each parameter.
You can see above that you go from two parameters quiet and splash to Four parameters.
Tap ctl+o to overwrite, then enter to save as current configuration.
Tap ctl+x to exit the editor.
Now run

sudo update-grub

Reboot and test.

15

It didn't work, unfortunately. It still cant identify an driver

16

Which kernel are you on?

uname -r

I wonder if you need to downgrade the kernel.

17

6.14.0-37-generic

18

You could try it with Zorin 17, it is still supported until 2027.
On linux hardware it is shown that this graphics works with ubuntu 22.04 Zorin 17 is based on.

But when Your BIOS is in UEFI, I would suggest to try it with GPT.
