[SOLVED] can't see tty after fresh install on macbook pro 11,2

shlyapa · 2020-09-01 01:27:36

it gets stuck on the boot log:

journalctl -b-1

http://ix.io/2vPm

if you search for login:auth, you can see there are login attempts when tty is hidden

i assumed it's graphics related and tried early KMS with i915.modeset=1 but no luck

lspci -k

http://ix.io/2vPH

/boot/loader/entries/arch.conf

http://ix.io/2vPK

/etc/fstab

http://ix.io/2vPL

any suggestions are appreciated.

Very weird, have you tried with nomodeset?
Is this from a mac? It seems to be a mac.
Also have you done early KMS with i915 on the initramfs?
If so, remove it and rebuild your initramfs...

Btw once you fix this beware of an update, tally2 is deprecated and as soon as you update you will have pacnews to apply to login and auth.

oh, thanks! nomodeset is for the win, didn't know that was an option.

and yes, that was a mac.

Nomodeset is not a permanent solution, it’s a workaround, but if that works then it’s an issue with i915 probably, and that still must be fixed...

Tho idk who’d to report in that case...

Also we still don’t know why i915 (if it’s indeed the culprit) is nuking the framebuffer...

Since it’s a mac, this should be good starting material, just in case it’s an already documented issue and there are more sane workarounds than just nuking KMS.

Also try to pass

i915.enable_fbc=0 i915.enable_psr=0

to the kernel parameters instead of "nomodeset"

i tried to use those

1) if i have i915 in /etc/mkinitcpio.conf (with or without intel_agp in front of it) then everything stops with this:

:: running early hook [udev]
Starting version 246.3-1-arch

it can only boot with nomodeset

2) if i remove i915 from /etc/mkinitcpio.conf passing any kernel options makes it boot without tty (except nomodeset)

---

also after it boots with nomodeset i get an error printed on the screen after some time:

snd_hda_intel 0000:00:03.0: HSW/BDW HD-audio HDMI/DP requires binding with gfx driver

i guess that happens because of nomodeset, can it maybe affect i915?

Do you only edit /etc/mkinitcpio.conf or do you also actually regenerate the initramfs?
Also (assuming it's still there) remove the "quiet" parameter.
If you setup a graphical.target (graphical DM) and remove "nomodeset", does that skip the TTY but ultimately get you a visible output on the DM?

i do regenerate it every time i edit /etc/mkinitcpio.conf

i don't have it anymore

i've just installed sddm (never used DM actually) but nothing changed (i saw it installed a bunch of X-related packages, just in case I didn't set up any of them)

journalctl log: http://ix.io/2vYd (i can see "Sep 02 10:03:36 taiga systemd[1]: Started Simple Desktop Display Manager.")

I just realized that the graphics card on this macbook pro which is Intel Iris Pro 5200 might not even be supported by xf86-video-intel and that people've been using fbdev driver

I guess my course of action would be to install X first and try it with fbdev

(I was hoping to try Wayland/sway instead of X)

There're no notable errors and the macbook should™ work "out of the box"

Did you have problems when instlling arch? Did you go for "nomodeset" then as well?
Try the LTS kernel.

you're absolutely right! I couldn't boot the latest iso due to a different error so I went for an older one which booted without nomodeset, but then after pacman -Syu I had to go nomodeset

yay, it works! thanks very much again for your help seth!

seth · 2020-09-03 15:05:33

Kernel regression, you should check whether it's fixed in a future kernel, otherwise raise a bug (because at some point this will hit the LTS kernel)

shlyapa · 2020-09-03 15:14:24

thanks! would it be right to assume that the subsystem is device driver infrastructure? never filed a bug on linux kernel.
