Intel i915 causing irrecoverable black screen (hybrid config)

Hello everyone,

I'm trying to install Archlinux on my laptop, but I'm unable to make the intel i915 driver to work properly. My laptop is a MSI GS63 powered by a i7 7700HQ with two graphic cards. This processor has a Kaby Lake microarchitecture that comes with a Intel HD Graphics 630. The dedicated GPU is a NVIDIA GeForce GTX 1070 Max-Q edition.

# lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Device 591b (rev 04) # Intel HD Graphics 630
01:00.0 VGA compatible controller: NVIDIA Corporation GP104M [GeForce GTX 1070 Mobile] (rev ff) # 1070 Max-Q 

With the latest kernel (4.13.3) I get a black screen when udev loads i915 driver. As of right now, I can only boot with i915.modeset=0. This also happens with the LTS and ZEN kernel variants. The intel_iommu=off does not help me in this case. Setting modeset=0 keeps me from running X and starting any desktop environment. I have installed bumblebee and bbswitch, and that seems to work. I can see the dedicated GPU switching on and off because of an amber/red GPU LED.

It looks like my LCD monitor is connected to the intel GPU and it can communicate to the dedicated GPU via PCI bus. This laptop has an HDMI output, which I believe it is hardwired to my nvidia GPU. I can get X to start on the HDMI output using nvidia driver but the main LCD (probably connected to my intel GPU) doesn't show anything. Using the HDMI setup, xrandr won't even show my main monitor as an option.

I had to boot with acpi_osi=! acpi_osi="Windows 2009" because lspci was hanging as per this discussion on Bumblebee project github

When I try to re-insert the i915 module with modeset=1.

# dmesg | grep "command line"
Kernel command line: initrd=\intel-ucode.img initrd=\initramfs-linux.img 
root=PARTUUID=2b54ee1c-05e1-465d-bcb1-1b0fa26ef21b rw acpi_osi=! acpi_osi="Windows 2009" i915.modeset=0
# rmmod i915
# modprobe i915 modeset=1

I get a warning from intel driver. This warning comes from i915/intel_dp.c line 143.

I don't know if that warning has anything to do with the black screen. But those console messages make it clear to me that the frame buffer is not getting the correct resolution. Even after the black screen, my computer continues to operate normally and I can ssh to it.

One thing I found intriguing is that backlight is not adjustable. After loading intel driver (with modeset=0). I get:

# ls /sys/class/backlight -lha

No matter what I write to /sys/class/backlight/intel_backlight/brightness, the actual_brightness does not change.

Things I have tried and didn't work:

I feel like I've exhausted my options. What else can I try?

Re: Intel i915 causing irrecoverable black screen (hybrid config)

What is the dmesg from a boot without i915.modeset=0 ?

Re: Intel i915 causing irrecoverable black screen (hybrid config)

Looks at least related to https://bugs.freedesktop.org/show_bug.cgi?id=102929 (happens at probing)
Since your nvidia chip is a full VGA device, you can either downgrade the kernel or try to deactivate the internal chip in UEFI/BIOS (if possible)

Re: Intel i915 causing irrecoverable black screen (hybrid config)

Unfortunately, I can't disable the internal chip. My BIOS is very limited. Do I have to recompile old kernels (I'm doing it right now and It takes forever to finish) or there is a way to download pre-built kernel packages?

Re: Intel i915 causing irrecoverable black screen (hybrid config)

https://wiki.archlinux.org/index.php/Do … g_packages
But for the kernel, there's also the linux-lts package.
Ensure to install the nvidia-lts packages as well!

Re: Intel i915 causing irrecoverable black screen (hybrid config)

Ok,

I've tried the following kernels:

  • Linux ZEN -> Same error

  • Linux 4.9 (LTS) -> Same error

  • Linux 4.12 --> Same error

  • Linux 4.4 --> I didn't get a black screen, but could not start X

I've also built a custom kernel (4.13) with a modified version of the file i915/intel_dp.c. I've basically commented out the line 143, and as expected, the warning didn't show up, but I couldn't get the driver to work.

Well, I've got nothing else to try. I think I should report this to upstream. This means I have to get in touch with intel. How do I do that?

Thank you for your help seth and loqs.

Re: Intel i915 causing irrecoverable black screen (hybrid config)

Linux 3.16?
Is the intel driver from the kernel or xf86-video-intel?
Do you get to the display manager?
Does tty switching work?
Bios update? Right?

I will try to think up something more. smile

Re: Intel i915 causing irrecoverable black screen (hybrid config)

Funny thing is when intel is loaded, I get absolutely no error on:

# cat /sys/class/drm/card0/error
No error state collected

I frankly don't know where is is the bug. It looks like the display outputs are listed on /sys/class/drm, but none of them is detected as connected to an actual display.

I've decided to give nouveau a chance and guess what? It also fails to load.

Re: Intel i915 causing irrecoverable black screen (hybrid config)

power saving failure? Try adding "i915.enable_rc6=0 i915.enable_psr=0" to the kernel parameters - notably PSR was enabled with 4.6 ... and is directly related to the link rate.
(The X11 failure might be whatever something else in response to using a dated kernel or so, maybe because the used DDX is then too new)

Re: Intel i915 causing irrecoverable black screen (hybrid config)

Hi everyone.

I'm in a similar situation except I'm not in Hybrid (blackscreen on gdm.service, no mouse, no tty, OS froze), I've read several others topics / links...

But me too cafe I frankly don't know where is is the bug.
I didn't try to boot with intel_iommu=off.
However I did try to boot with seth kernel paramater seems ok for me now "i915.enable_rc6=0 i915.enable_psr=0"
Thanks Seth

FYI :
Laptop : EliteBook 840 G3
BIOS update : Last version : OK

I couldn't collect any dumps/errors event by reproducing the error, and then boot arch-iso; arch-chroot check log whithin :

cat /sys/class/drm/card0/error
No error state collected
dmesg -T

Those conflicts are normal ?

Any explanation about this situation ?
Seth, How did you guess it could be linked to power saving failure ? And thanks your kernel parameters seems solve my issue.

Thanks for your feedback.

Re: Intel i915 causing irrecoverable black screen (hybrid config)

Thank you for reporting your experience. I'll try those power saving options with debug mode activated to investigate a little further.

Cheers,

Re: Intel i915 causing irrecoverable black screen (hybrid config)

The "conflicts" are normal - means you need a reasonably recent X11 server and none of the older intel driver packages installed. That's just for package management.

About the cause: Jedi senses tongue
(When he mentioned the difference between 4.4 and 4.9, that rang a bell - the rest is explained in comment #11 and I just took an informed guess from there)

You may want to try whether "i915.enable_rc6=0" is actually required.

Re: Intel i915 causing irrecoverable black screen (hybrid config)

You're welcome cofe,

I'll try as well to dig it more if I can.
That's now clear Master Jedi, you used the force I understand better the issue now. tongue
I"ll try this parameter later on.
Thanks

Re: Intel i915 causing irrecoverable black screen (hybrid config)

Hello,

I have the same issue with my MSI GE63 (with an Intel i7 7700HQ and a Nvidia GTX 1070, so almost the same hardware as cafe's).
I tried about the same things as you, with no better luck. Additionally, I tried to boot with "i915.enable_rc6=0 i915.enable_psr=0" as kernel parameters, like seth suggested, but it didn't solve the problem.
I also tried to use the 14.4-rc5 kernel directly compiled from source, since I saw there was some work on i915 (I didn't take the time to read the commit message, but I had hopes tongue), but it failed too.
And finally, I updated my UEFI, and it didn't help.
Sadly, I don't have any more clue about how to fix it.

Here is the relevant part of my dmesg, if it can help (with the 14.4-rc5 kernel but without the mentioned kernel parameters):

Re: Intel i915 causing irrecoverable black screen (hybrid config)

Yep, that's the same warning that I get. I fell like we really need to submit this to Intel. I just don't know if this should be sent to the i915 team or the drm folks. Keep me posted on your progress!

Re: Intel i915 causing irrecoverable black screen (hybrid config)

a) looks like a stack corruption (the call stream doesn't seem to exist in the code)
b) http://www.spinics.net/lists/intel-gfx/msg141969.html - seems the function on the end is being dropped altogether

Re: Intel i915 causing irrecoverable black screen (hybrid config)

Hi everyone,

After testing the 'thing' I confirm the kernel parameters didn't work : "i915.enable_rc6=0 i915.enable_psr=0"
In fact my error is very random*, depending the D-day and/or the mood of my laptop, I dunno...

I think we should submit this issue to intel.

I noticed there is no problem booting on CLI, so I finally use my dirty quickwin (stable for now) :
LOL; don't laught, but it just work perfectly actually smile

0. boot ISO & mount /dev/sdx & archroot /mnt
1. sudo systemctl disable gdm.service
2. Remove kernel parameters i915* from grub.cfg
3. reboot (now in cli)
4. vim ./.zshrc / ./.basrc
    alias ok="sudo systemctl start gdm.service"
5. . ./.zshrc | . ./.bashrc
6. ok

*Random kernel bug line is the same for me :1639

Re: Intel i915 causing irrecoverable black screen (hybrid config)

See Arch_Build_System to obtain the source for the kernel as used by arch.
Might also try the linux-drm-tip kernel which has the function causing the warning already removed but I can not recommend the PKGBUILD in linux-drm-tip-git uses.
Edit:

Re: Intel i915 causing irrecoverable black screen (hybrid config)

Hello,

Thanks for your replies.

Yes the error is the same (our hardware is very similar too), but I was actually using the 4.14-rc5 kernel.

So I just tried this kernel. I did not follow your instructions for the installation since it was already done when I saw your edit. Instead, I just cloned from git://anongit.freedesktop.org/git/drm-tip.git and compiled it manually,
following these directions; but I believe it makes not much difference (does it ?).
So, the issue was unfortunately not solved, but the warning triggered was different (although, it seems to refer to the same problem, it's just worded differently).
Here's the relevant part of my dmesg:

Re: Intel i915 causing irrecoverable black screen (hybrid config)

I agree with you it looks as though the issue is not resolved just the removal of intel_dp_num_rates caused the issue to be detected at a different point.
As it is still happening using drm-tip I would report it upstream as a bug against product DRI and component DRM/Intel.
Please include all the information requested in how to report.

Re: Intel i915 causing irrecoverable black screen (hybrid config)

Hi everyone. I'm having the same error.

Kernel and system architecture: 4.9.56-1-lts x86_64

dmesg: https://pastebin.com/2xuTZ75s

lsmod | grep i915: https://pastebin.com/2i1G3JJ5

lsmod: https://pastebin.com/kxwXY7T0

lspci | grep intel: https://pastebin.com/jW807Jw1

I tried the kernel parameter intel_iommu=off but don't solved my problem. So I used a kernel parameter drm.debug=0x1e and log_buf_len=1M without intel_iommu=off for more information in dmesg in specific DRM debug. Anyone know how to solve this problem?

The relevant part of dmesg is this:
[   38.102022] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun
[   38.103242] [drm:intel_set_pch_fifo_underrun_reporting [i915]] *ERROR* uncleared pch fifo underrun on pch transcoder A
[   38.103269] [drm:intel_pch_fifo_underrun_irq_handler [i915]] *ERROR* PCH transcoder A FIFO underrun


Cheers.

Re: Intel i915 causing irrecoverable black screen (hybrid config)

Unlikely. You're using the lts kernel and not only miss the intel_dp_*connector segfaults but even have success in

[   37.375129] [drm:intel_hdmi_init_connector [i915]] Adding HDMI connector on port B
[   37.375159] [drm:intel_hdmi_init_connector [i915]] Using DDC pin 0x5 for port B (platform default)
[   37.375198] [drm:intel_dp_init_connector [i915]] Adding DP connector on port B
[   37.375229] [drm:intel_dp_init_connector [i915]] using AUX B for port B (platform default)

Try passing "iommu=off i915.enable_psr=0 i915.enable_rc6=0" and in case that works, only "i915.enable_rc6=0"

I used those parameters right now and don't solved, simply my output of log says it's doing starting LXDE and graphical mode in Arch Linux but doesn't show this.

See my dmesg output, please: https://pastebin.com/2xuTZ75s

What's wrong there?

And the journalctl -xe | grep intel command: https://pastebin.com/gwDBVjet

And dmesg | grep DP: https://pastebin.com/6k9cSd5e

I was running all those commands after the boot as tty (Ctrl + Alt + F2) with those kernel parameters: ... iommu=off i915.enable_psr=0 i915.enable_rc6=0 drm.debug=0x1e log_buf_len=1M


Cheers, seth. Thanks for the help.
