Qubes 4.1 Installation Issues for Legion 7

I’ve been trying to install Qubes on my Legion 7 Gen 6 (AMD Ryzen 9 5900HX with RTX 3080) for the past several months now with not much luck. I’ve tried a variety of solutions found on the forum here and some have led to different results.

I’ll try to list everything I’ve done to hopefully provide a clear picture to my problem so this may be a bit long. I have tried using two different 16 gb flashdrives (using Rufus in dd mode) so that could be the issue, however the initial GRUB menu does appear and I have booted other Linux installers from them. I have also been using the newer builds from https://qubes.notset.fr/iso/, I believe I’ve tried probably 7 or 8 of them as well as a Qubes 4.0 image from one of the other mirrors.

The first time I tried to install Qubes, I selected the Install Qubes option from the grub menu and was greeted by a complete black screen. Trying the verbose mode, it went through the verbose boot with the very last line being “Xen is relinquishing vga console”.

I tried adding the “vga=,keep” (I have also tried “vga=current,keep” which I presume does the same thing) and after even more verbose text that appears slowly one line at a time, it then hangs on “[ 512.520643] ACPI: PM: Power Resource [PG00]”. I am not quite sure what this means other than something about the power manager.

After here I tried a variety of other boot arguments found on this forum in the grub, I didn’t keep complete track of every combination I used but here’s a list. Some of them I put on the xen.gz line and some on the second line, as far as I’m aware I was putting them on the correct line.

  • “console=none”
  • “dom0_max_vcpus=1”
  • “dom0_vcpus_pin”
  • “i915.force_probe=*”
  • “nomodeset=0”
  • “i915.alpha_support=1”
  • “iommu=no-igfx”
  • “nouveau.modeset=0”
  • “rd.driver.blacklist=nouveau”
  • “video=vesa:off”
  • “acpi=off”

Both the arguments about dom0 vcpus were needed to not get the same freeze on Power Resource, but would lead to a soft lockup on the CPU, that seemed to loop.

Most of the verbose I couldn’t understand but some parts stood out, all of the below is without using arguments about dom0 vcpus.

“[503.363866] ACPI: BIOS Warning (bug): Incorrect checksum in table…” followed by text that I failed to copy.
“[518.022672] ACPI BIOS Error (bug): Could not resolve symbol(_SB.PCI0.PB2], AE_NOT_FOUND (20210730/dswload2-162
[518.022672] ACPI Error: AE_NOT_FOUND, During name lookup/catalog(20210730/psobject-220)
[518.022672] ACPI: Skipping parse of AML opcode: OpcodeName unavailable (0x0010)
[518.022672] ACPI: 18 ACPI AML tables successfully aquired and loaded
[518.022672] ACPI: [Firmware Bug: BIOS _OSI(Linux) query ignored”

Any suggestions for what to try would be appreciated and let me know if any other specific information would be helpful.

After trying the second release of Qubes 4.2 on https://qubes.notset.fr/iso. I managed it get it installed. I used the boot arguments:

  • console=none
  • vga=,keep
  • dom0_max_vcpus=1
  • dom0_vcpus_pin
  • acpi=off
  • nomodeset=0

Everything seems to be working as expected. I won’t be using Qubes for anything too important until a proper release of Qubes 4.2 comes out but I’ll post any other issues and fixes I find on here for anyone facing similar issues.

Hi there - i too am fighting my Legion 7 attempting to get it to install and boot from USB drives.

Could I ask :

  • Second Release : is that the 8th March one in that long list? (did subsequent releases not work for some reason?)
  • I’m assuming those boot arguments are required for a successful install? - i’ve attempted to boot with latest kernal and I can progress through install screens but when it comes to -actually- install it took…maybe 6/7 hours gently trickling along before it eventually crashed out.

(i’m assuming, but I welcome being corrected, that the acutely painful slow install time indicates that it’s borked?)

Any other advice on making the Legion 7 work with Qubes would be gratefully welcome.
