Hi,

I installed qubes on a brand new Lenovo X1 Carbon, but encountered a lot of issues.

1. The wifi is unavailable. I have no idea why, but I did boot it into an ubuntu live cd once, and the wifi card was found on ubuntu. This gist (https://gist.github.com/holiman/83c76e4cd98d087719773486a77d9112) contains the `lspci` and `lsusb` from both qubes and ubuntu.

On qubes, the relevant pci device is

00:14.3 Network controller: Intel Corporation Device 51f0 (rev 01)

On ubuntu, it is identified as:

00:14.3 Network controller: Intel Corporation Alder Lake-P PCH CNVi WiFi (rev 01)

2. Graphics is a mess. Already at the installer-stage, things were really bad. A drop-down window slide took on the order of seconds. I went through with the installation anyway, and the graphics are really really slow. Dropping down the upper-left menu takes ~1s, first showing a fragmented puzzle, and a bit later filling out the missing bits in the puzzle, and the menu is shown. I have a video, not sure if it's worth posting anywhere.

Fwiw,

- the bios does not contain any option to toggle between integrated / discrete graphics.

- I have not yet tested any of the tricks (i915.enable_psr2_sel_fetch=0) mentioned on https://forums.lenovo.com/t5/Fedora/Fedora-on-X1-Carbon-Gen-10/m-p/5135869?page=1.

Some follow-up. I tested also with a Fedora LiveCD, results are on the
gist
(here:https://gist.github.com/holiman/83c76e4cd98d087719773486a77d9112#file-fedora-live-txt
) .

The Fedora livecd worked flawlessly, both wifi-wise and graphics-wise.
It was a fedora 36 -- whereas dom0 is still on Fedora32.

Is it in any way possible to try out some experimental repo where dom0
is more recent?


Cheers,

Thank you Martin for your HCL report. For now I filed it as works: 'no' ... let us know when this becomes a 'partial' with 'troubleshooting required'.

Your report is [online](https://www.qubes-os.org/hcl/#lenovo_thinkpad-x1-carbon-10-21cbcto1ww_i7-1270p_integrated-graphics-iris-xe_martin-holst-swende_r4-1) now.

No, but I would like to know if your problems go away with
kernel-latest. If they do not, then this means that either Xen does not
interact well with Linux’s graphics drivers, or that the Mesa version is
too old for your hardware.

Unfortunately, they do not. I did that as the first thing after getting
wifi to work, so the version 5.18.9-1 in the HCL, is kernel-latest.

Happy to try out any suggestion/experiment.

1. Does i915.enable_psr2_sel_fetch=0 help?
2. What X11 driver is Xorg using? If it is using Intel, does
modesetting help? If it is using modesetting, does Intel help?
3. Does HVM sys-gui-gpu work? What about PV (not PVH!) sys-gui-gpu?

If PV sys-gui-gpu with a dom0-provided kernel works, then the problem is
almost certainly old dom0 userspace: either an old X server, old Mesa,
or both. If you could build modern Mesa and/or X11 for dom0 and try
again, that would be awesome.

No, no change that I can see.

More full logs/notes can be found at
https://gist.github.com/holiman/83c76e4cd98d087719773486a77d9112#file-dom0_testing-txt

I'm not sure how to interpret the logs, it looks to me like "intel no,
modesetting yes". Not sure how/what to change here, given a nudge in the
right direction I can try to explore it more.

I don't have a sys-gui-gpu at the moment, but will test that. This page
(https://www.qubes-os.org/doc/guivm-configuration/) is still the most
relevant/recent description, right?

Left for future reference, I'm taking baby steps here :)

That is what it looks like to me also.

I think so? I don’t use sys-gui-gpu myself, and I will admit that there
are quite a few bugs when using it. Still, if it works, then the
possible parts of the code that could be to blame is much lower. If
sys-gui-gpu in PV mode works, then the problem is almost certainly the
userspace drivers (Mesa). If sys-gui-gpu in HVM mode works, but it
fails in PV mode, then the problem is likely in the way i915 and Xen
interact.

I have tested this now. When I boot, the problem remains. Opening the
Qube Manager shows that the sys-gui-gpu qube is not running. I tried
starting it from the manager,
and it led to immediate black screen, requiring a hard shutdown. The
logs for that qube are here:

https://gist.github.com/holiman/83c76e4cd98d087719773486a77d9112#file-guest-sys-gui-gpu-log


https://gist.github.com/holiman/83c76e4cd98d087719773486a77d9112#file-guest-sys-gui-gpu-dm-log

I then switched it to PV mode. Same thing, does not startup +
blackscreen if I start it explicitly.

dom0 will kernel panic if the GPU is removed from it while in use. I
recommend preventing the i915 kernel module from being loaded in dom0
via the dom0 kernel command line.

I've tried some variants now. Disabling i915 (by moving the driver flie) doesn't do much. It boots up as usual, same problems, and if I try to boot the sys-gui-gpu qube, it blackscreens and requires hard shutdown.

New development: I used the boot param: module_blacklist=i915 (and the drivers were also removed from the filesystem).

This time, there were no graphics glitches. However, the sys-gui-gpu did not come up. I started a work -qube Firefox, thinking it maybe would kickstart the gui vm, but no. 

So maybe those gui-vm config steps do not fully enable it? I eventually (again) tried manually starting it, with the result of immediate blackscreen freeze. 

Not sure where that leaves me? I don't even know what the whole i915 thing is all about, what is it supposed to improve?

To follow up after a bit more experimentation.

- Using the boot param 'module_blacklist=i915' makes things work pretty
much ok. No obvious graphics glitches, it's able to play videos without
the fans spinning up like crazy.

- The PCI device for networking seems unsupported, so usb-wifi card is
needed to get networking working.

- I get no sounds. Pavucontrol lists "Dummy Output" as the only
available output device, so I guess the PCI device for sound is also not
supported. (My old laptop has "Built-in Audio Analog Stereo" output
device in pavucontrol).

- I did not get the whole sys-gui-gpu thing to work sufficiently to test
it, not sure if there's anything left to explore in that area. Mostly I
think a more recent kernel is the thing that will eventually solve this.

Cheers,

Martin

Interesting!

I tried it now, but unfortunately I encounter  a core dump, similar to one person in that issue. However, I don't think I have any spelling errors, and definitely no erroneous quote characters.

Well done!

How did you enable the 5.18 kernel? I've tried with 'qubes-dom0-unstable' and listing the available kernels, but it shows only a few versions of 5.15 as installation candidates.

Cheers,

Martin

There will still be a graphical glitch when entering the LUKS password but everything else works fine. 

To fix WiFi network you need to use kernel 5.15.64-1.fc32 on sys-net. Most of the time the network adapter works, sometimes it doesn't work on boot but restarting sys-net gets it working. Once I have had to reboot the whole computer to get it working.

That's odd, since it doesn't seem to work for me.

Related question: I've been searching and haven't found -- where can I check the most recent packages on the various channels (stable / unstable / testing / experimental etc) . Would be nice to be able to check what different kernels are available via what channels.

Update on this.

I was able to update sys-net to use 5.15.64-1.fc32, and can confirm that it fixed the wifi issues.

I also updated the dom0, to 5.19.9-1.fc32. However, that didn't go as well, and the system now crashes on boot -- sometimes I get to enter the LUKS password, sometimes it crashes before that.

If I do module_blacklist=i915, then I can bypass the crash and enter the system.

Yeah, In the process of trying to get qubes to work I tried 5.19.9-1.fc32 but it kept crashing at the Luks password screen. The only kernel that seems to work is 5.18.16-1.fc32.qubes.x86_64 but if "sudo qubes-dom0-update kernel-latest" doesn't work for you then I don't know how else you would get it.

I installed an early version: 5.19.14-1  (see https://github.com/QubesOS/qubes-linux-kernel/pull/649#issuecomment-1268337609).

Unfortunately, it didn't solve the issue -- crash at luks screen. However, I did manage to snap a picture of the crash this time. See attached.

Hello,

 Could it be that current sys-gui-gpu cannot work because of  : https://lists.xenproject.org/archives/html/xen-devel/2022-10/msg01820.html ?

Another follow-up:

I now installed kernel version `6.0.7-1.fc32.qubes.x84_64`, and now I
get past the crash at the luks-screen.

I am not 100% sure which kernel fixed it, but ISTR trying with an
earlier 6.0-version a few weeks ago without success.

Going to test a bit more, but looks good so far!

Another follow-up. The audio (tested via a fedora-based work-qube) is
hilariously distorted. Listening to some music through it made it sound
like some extremely experimental avant-garde stuff.
