Failed Light Display manager

I started garuda from a USB stick.
The error message "Failed Light Display Manager" was displayed.
How can I remove error message "Failed Light Display manager"? Is there a boot option for this?

Hi there, welcome.
Try with open source drivers and disabling secure boot and fast boot in BIOS


Yes i use open source drivers secure boot is disabled fast boot is disabled. But its dont start

Just in case, but it should not be the issue, checksum verified?
What tool did you use to burn the USB?


The sha256sum is ok.
I use ventoy.

That's a bit strange, quite frankly.
What are the specs of your hw?
What Garuda edition did you download?

I have garuda-xfce-linux-zen-220101
My Motherboard is Asrock B450 Pro
My CPU is AMD Ryzen 5 2400 g
I have 8 Gb Ram

I think the only option is to try some boot parameters pushing E in the open source driver GRUB line.
I'd start with iommu=soft
If that doesn't help, you could try e.g. forcing the amdgpu driver instead of the Radeon one (I assume the GPU is AMD).
If I remember correctly this was something like
radeon.si_support=0 radeon.cik_support=0 amdgpu.si_support=1 amdgpu.cik_support=1 modprobe.blacklist=radeon


The screen remains black afterwards .

I once had a Ventoy problem with a perfectly good iso, but maybe a few lame cells on the flash disk and couldn't quite get through the installer either. If you still have the iso on your computer, try to re-save it to the Ventoy. Don't delete the old one, just rename it "zz-do_not_use" or similar to avoid reusing that piece of the drive again (if that is the issue).

I also have ventoy

I apologize, it sounds like I was unclear. What I mean to say:

  • A few corrupted cells on your USB drive will not be detected by Ventoy, but will disrupt the installation.
  • To check, add the garuda-xfce-linux-zen-220101 ISO to the Ventoy again and re-try the installation.
  • Do not delete the old image from the Ventoy disk, or Ventoy will potentially reuse those same corrupted cells in the future. Instead, rename the old image (any name) and just leave it.

This might not be a fix, but if the installer still is not working for you it is worth a shot.


The iso is good and not brocken!

The message I am trying to communicate is that the ISO can be good but some of the physical cells on the USB drive--the actual device--can be corrupted.

If this were the case (nothing wrong with the ISO), my advice is rename the old image (right where it sits on the Ventoy) and save the perfectly good ISO to the disk again, a second time. Two of the same image saved to the Ventoy disk at the same time.

Now I'm a bit lost.
This looks like a virtual machine, is it?
VMs are not officially supported, but I don't understand the relation with the initial thread, which was for a non-booting USB.
What is the actual problem?


What is the actual problem?
I cant start from USB.

Use other usb-stick otherusb port and try other hardware for test.
