[SOLVED] Thinkpad X1 Extreme crash black screen with flickering lines.

Hi everyone,

Since a few weeks my laptop randomly crashes, with a black screen with flickering white lines at the top. At least a few times every day.

I suspect a driver issue or a hardware fail. I don't know how to start investigating this further. The (quick) hardware tests in the BIOS say everything is alright.

Any hints on where to start looking, or what info to provide, would be nice!

Thanks in advance,
Erik

Re: [SOLVED] Thinkpad X1 Extreme crash black screen with flickering lines.

Have you tested the non LTS kernel? Can you switch TTYs when this happens? If you can't, enable sysrq reboot with REISUB when the flashing happens, and then post a

sudo journalctl -b-1

after rebooting from a crash. https://wiki.archlinux.org/title/List_o … n_services

Re: [SOLVED] Thinkpad X1 Extreme crash black screen with flickering lines.

Hi V1del,

Thnx for your response.

I have tried to reboot into the regular kernel, but it ends up in emergency mode for some reason. However, a few days ago I booted the arch rescue/install usb and it crashed once there too.

I enabled sysrq with REISUB. I was able to reboot this way under normal circumstances, but when another crash occurred I was NOT able to reboot this way. So I just turned of the power and after reboot I executed:

sudo journalctl -b-1

I posted the output here: https://gist.github.com/t638403/e20ea9f … 47fc05f8a5

EDIT: typo in command

Re: [SOLVED] Thinkpad X1 Extreme crash black screen with flickering lines.

The command is with -b-1 the number not the letter, and since this output will be from the current not crashed boot doesn't contain much (other than a metric ton of kubernetes docker spam, are you sure you are not just running out of resources?)

Re: [SOLVED] Thinkpad X1 Extreme crash black screen with flickering lines.

Sorry, made a typo in my forum post. I am aware that it is -b-1. I understand that the -1 refers to the one boot before the current/last one.

I removed the microk8s and minikube stuff since I do not use it, so the spam is mostly gone. I do use docker though.

I'll wait for the system to crash again, and I will report the output of journalctl -b-1 again.

Thnx so far

I had another crash.

The result of 'sudo journalctl -b-1' :

Re: [SOLVED] Thinkpad X1 Extreme crash black screen with flickering lines.

Unfortunately still having troubles. Anybody out there who has an idea of how to pin point my crashing problems as either a software related issue or a hardware related issue?

Re: [SOLVED] Thinkpad X1 Extreme crash black screen with flickering lines.

Did/could you reboot with REISUB, can you link a video showing what you see? There's nothing suggesting any sort of issue I can see in that log, if that is literally where it stops, then you have a hard crash that can't sync to disk at all , in which case this sounds like a very low level hardware issue. The only software suggestion I have is try the normal kernel, and generally make sure xf86-video-intel is not installed. Can you post a xorg log?

Re: [SOLVED] Thinkpad X1 Extreme crash black screen with flickering lines.

Hi,

I tried rebooting with RESIUB but it did not work.

The symptoms are very much like described in this reddit post https://www.reddit.com/r/thinkpad/comme … ashes_and/. My screen looks something like this also https://i.imgur.com/yzyp7z3.jpeg.

I do have xf86-video-intel installed I noticed. And when I remove it, Xorg wont start. I'm interested in any info/docs on how to setup my video card the right way then.

My xorg log didn't seem helpful. I will look into this first. It contained some logs about a crash that I figured was unrelated. Something about a second screen (I do not use a second screen this is another issue of mine, which could be related to the xf86-video-intel problem)

Thnx again!

Re: [SOLVED] Thinkpad X1 Extreme crash black screen with flickering lines.

I installed the nvidia (lts) package in stead of xf86-video-intel. I will monitor how it will go from here (for a week or so). If I have no crashes anymore I will close this issue.

Re: [SOLVED] Thinkpad X1 Extreme crash black screen with flickering lines.

I had another crash, but this time the screen/keyboard/mouse froze. So no black screen with white lines at the top this time.

REISUB didn't work.

Re: [SOLVED] Thinkpad X1 Extreme crash black screen with flickering lines.

If xorg doesn't start without xf86-video-intel then you have configuration explicitly referencing the intel driver which you'd have to remove.

Frome the posted corruptions I'd try to disable psr and/or fbc: Add

i915.enable_psr=0 i915.enable_fbc=0

to your kernel parameters, maybe check https://wiki.archlinux.org/title/Intel_ … Intel_CPUs as well.

Re: [SOLVED] Thinkpad X1 Extreme crash black screen with flickering lines.

I deleted xf86-video-intel package and deleted the explicit Xorg config. Running the nvidia proprietary driver now.

I have my second monitor working again, which is awesome! I finally understand what the issue was there... Kind of obvious though... Running the right driver basically.

I am trying all kernel options one by one.

I have tried i915.enable_psr=0 but it did not have an effect since mouse/keyboard/screen froze again.

Trying i915.enable_fbc=0 currently.

If the system keeps freezing I will also try one by one all the params from the link.

intel_idle.max_cstate=1 i915.enable_dc=0 ahci.mobile_lpm_policy=1

Re: [SOLVED] Thinkpad X1 Extreme crash black screen with flickering lines.

I have tried them all one by one. Keeps crashing.

I will now try them all at once. If the crashing stops, I will remove them one by one to figure out which are the ones I need.

Re: [SOLVED] Thinkpad X1 Extreme crash black screen with flickering lines.

There's no logs or anything from the crashes, I'd contact lenovo/RMA the thing. The only slight hope I'd see is a UEFI update but the version looks quite new already.

Re: [SOLVED] Thinkpad X1 Extreme crash black screen with flickering lines.

V1del, I thank you very much for taking the time to respond en support me with new insights. You're a kind person.

I will close this issue now.

Re: [SOLVED] Thinkpad X1 Extreme crash black screen with flickering lines.

I am running the latest kernel now. Like advised early on in this thread. Earlier I had some troubles getting it to work, but today it worked out.

```
$ uname -a
Linux thinkpad 6.0.5-arch1-1 #1 SMP PREEMPT_DYNAMIC Wed, 26 Oct 2022 15:25:45 +0000 x86_64 GNU/Linux
```

If this does not work, I am going to apply the different kernel params again (see above). I don't know if that makes sense, but going to try it anyways.

Another crash. Setting all kernel params again.

Yet another crash. I give up.

Re: [SOLVED] Thinkpad X1 Extreme crash black screen with flickering lines.

Final status. I have been able to run windows on the device. Same behaviour. Complete freeze with no keyboard and mouse. I am concluding that this must be hardware failure.
