[SOLVED] TTYs frozen, only partially rendered

Edit 2: Two solutions:

Option 1: Disable onboard VGA in BIOS

Option 2:

# /etc/modprobe.d/i915.conf
install i915 /bin/true

Edit: Downgrading nvidia fixed it (of course). Not sure what issue was introduced between 515.57-5 and 515.57-9 though.

downgraded linux (5.18.14.arch1-1 -> 5.18.11.arch1-1)
downgraded linux-firmware-whence (20220708.be7798e-1 -> 20220610.7b71b75-1)
downgraded linux-firmware (20220708.be7798e-1 -> 20220610.7b71b75-1)
downgraded linux-headers (5.18.14.arch1-1 -> 5.18.11.arch1-1)
downgraded nvidia (515.57-9 -> 515.57-5)

Not even sure what terms to use to describe what's happening, so here's a picture of TTY2:

The system is otherwise functional. I'm not coming up with the right search terms to figure out what's happening here though.

Not seeing anything helpful in the journal or xorg logs.

Any thoughts?

Nothing. The critical downgrade was the kernel, but issues w/ nvidia and 5.18.14 are all over the place recently.

https://bbs.archlinux.org/viewtopic.php … 9#p2048529 and https://bbs.archlinux.org/viewtopic.php … 2#p2048532

Though yours *looks* more like  https://bbs.archlinux.org/viewtopic.php?id=278131 (apparently cold boot problem, only)

Thank you for the quick response. I read through those discussions and I'm having a hard time understanding if anyone has narrowed down the cause. Since my system actually boots to X I can't complain, but I also don't understand why we're experiencing the issues so differently.

Is there an official bug report for this, and are there any logs I can assist with? Is my best course of action to just wait this out, or do I have a configuration issue I need to deal with?

Re: [SOLVED] TTYs frozen, only partially rendered

loqs is running a git bisect on the nvidia related regression, you can test those kernels are report your findings
https://bbs.archlinux.org/viewtopic.php … 9#p2048699

But you should first clarify whether this is a cold-boot issue (in which case https://wiki.archlinux.org/title/Kernel … _KMS_start might be a simple way out)

Re: [SOLVED] TTYs frozen, only partially rendered

I can confirm that I'm still running into this issue on 5.18.15.arch1-2

Sorry for my ignorance here, but I'm struggling to figure out what a cold boot actually is. I'm using systemctl poweroff and systemctl reboot to control power state, and I run into this situation in both cases.

Re: [SOLVED] TTYs frozen, only partially rendered

Does it happen if you only boot the multi-user.target (2nd link below), get a cup of coffee and then start the graphical.target manully after the delay?

So this has an interesting result... I booted into the multi-user target with a kernel parameter and did not get a TTY at all, just a black screen. I could hear the disk grinding away for a bit and was able to reboot with sysreq b. Seems like it could be a graphical driver issue?

I'll see if I can find something obvious in the logs but haven't had much luck in the past. Not really sure how to proceed from here. Ideas?

Post the journal for that boot.

Can you boot w/ "nomodeset" (along the multi-user.target)?

nomodeset (and removed quiet) retained the screen which showed that multi-user.target was triggered, but then hung on that line

multi-user.target

multi-user.target + nomodeset

This indeed is very most likely the family of https://bbs.archlinux.org/viewtopic.php … 0#p2048820 issues.
https://bbs.archlinux.org/viewtopic.php … 9#p2049559 suggests that blacklisting i915 (and only use the nvidia driver/chip) may allow you to get around the issue.

You're right, thank you very much! Seems like some other modules are loading it (not sure how to check) so I did the following:

# /etc/modprobe.d/i915.conf
install i915 /bin/true

Does this mean it's a change in the kernel that introduced the problem? Will blacklisting the i915 module cause issues?

As an aside, I've had an ongoing issue for months now where picom will not draw windows for a session, seemingly at random, but resolves after killing i3 without a full reboot. That preceded this TTY problem but seems to have gone away with this fix too(?)

It very much looks this way and nvidia will probably have to align their driver to that (iirc. the nvidia-opend driver is patched, but requires a turing or newer chip)

Will blacklisting the i915 module cause issues?

Since it doesn't seem like you've any outputs attached to the intel chip and are using the nvida one anyway, it's probably been just dead weight so far.
