[i915] Black screen when I login in using kernel 5.8.0-59 but not 5.8.0-25

[Anatoli Navahrodski]

There was also no brightness setting. I have reinstalled ubuntu 3 times already. This happened after the updates on June 24th.
The only solution is not to install ubuntu updates. As soon as I install updates, there is a black screen.

[Daniel van Vugt (vanvugt)]

Sounds like bug 1930733. Please look in your kernel log:

  journalctl -b0

or

  journalctl -b-1

to verify.

[Anatoli Navahrodski (anatolii1309)]

I do not understand what to look for and where. Maybe this?

[Daniel van Vugt (vanvugt)]

OK, please just run these commands:

  journalctl -b0 > journal0.txt
  journalctl -b-1 > journal-1.txt
  journalctl -b-2 > journal-2.txt
  journalctl -b-3 > journal-3.txt

and then attach the resulting text files here.

[Anatoli Navahrodski (anatolii1309)]

I did how you asked.

[Daniel van Vugt (vanvugt)]

Can you state which "version" works and which doesn't?

[Anatoli Navahrodski (anatolii1309)]

The version higher than 5.8.0.59 does not work. I also made commands under the root in this version today.
apt update
apt upgrade
But it still doesn't work.

5.8.0.25 works. Loading. I can't see a black screen and can adjust the brightness of the screen.

[Anatoli Navahrodski (anatolii1309)]

Maybe this will be important. The computer took a very long time to shut down before the crash. This is usually less than 5 seconds.

[Anatoli Navahrodski (anatolii1309)]

I will also add information that this happened in version 20.04 (I had it at the beginning). I thought the problem was in the version and first updated to 20.10. It did not help. Then I upgraded to version 21. It didn't help either.
I am currently using 20.10 version.

[Anatoli Navahrodski (anatolii1309)]

These are the settings in the working version

[Daniel van Vugt (vanvugt)]

Thanks. This sounds like it might be a regression in the Intel kernel graphics driver "i915" in version 5.8.0-59 since that's probably what's driving your primary monitor, but the Bug Description also mentions that your Nvidia driver is broken for that kernel version:

 nvidia, 460.80, 5.8.0-59-generic, x86_64: installed (WARNING! Diff between built and installed module!) (WARNING! Diff between built and installed module!) (WARNING! Diff between built and installed module!)

Please try:

1. Uninstall the Nvidia driver.
2. Reboot.
3. Reinstall the Nvidia driver.
4. Reboot.

and tell us if the problem still happens.

[Anatoli Navahrodski (anatolii1309)]

The problem has not gone away. I uninstalled and installed again.
I did according to this instruction.
https://phoenixnap.com/kb/install-nvidia-drivers-ubuntu

Maybe I did what was wrong?
The screen is still black.
Can you write what commands to make?
I saw that the nvidia 460 drivers were installed. But the screen is all black.

[Daniel van Vugt (vanvugt)]

Ideally a broken Nvidia driver shouldn't cause this problem, because I think it's usually the Intel GPU that's wired to the laptop display. So the problem might still be the Intel driver. To find out for sure, can you please uninstall the Nvidia driver and then reboot?

Please then also run:

  uname -a > uname.txt
  lspci -kv > lspci.txt

and attach the resulting text files here.

[Daniel van Vugt (vanvugt)]

OK it looks like you successfully uninstalled the Nvidia driver. Does this bug still happen?

[Anatoli Navahrodski (anatolii1309)]

yes. The screen is still black

[Daniel van Vugt (vanvugt)]

OK that's helpful information. It means this is a bug in the Intel kernel driver "i915".

[Daniel van Vugt (vanvugt)]

Next please try logging into both 'Ubuntu' and 'Ubuntu on Wayland'. You can select which using the button in the bottom right corner of the login screen.

[Anatoli Navahrodski (anatolii1309)]

Sorry. Maybe I was wrong? I made these commands in the version that works. Can I do this in a version that doesn't work?
  journalctl -b0 > journal0.txt
  journalctl -b-1 > journal-1.txt
  journalctl -b-2 > journal-2.txt
  journalctl -b-3 > journal-3.txt

[Anatoli Navahrodski (anatolii1309)]

I managed to log in via recovery mode.
But I cannot change the brightness. Looks like the driver is not installed

[Anatoli Navahrodski (anatolii1309)]

Should I choose 460?

[Daniel van Vugt (vanvugt)]

> Sorry. Maybe I was wrong? I made these commands in the version that works.

You didn't make any mistake. journal-2.txt and journal-3.txt are from the version that does not work.

> Should I choose 460?

If you need the Nvidia driver to use the machine then yes you can reinstall it. I only wanted it uninstalled in order to prove this bug is in the Intel driver.

Next please try logging into both 'Ubuntu' and 'Ubuntu on Wayland'. You can select which using the button in the bottom right corner of the login screen. Do either of those work with 5.8.0-59?

[Daniel van Vugt (vanvugt)]

Note you will need to keep the Nvidia driver UNINSTALLED in order to test 'Ubuntu on Wayland'.

[Anatoli Navahrodski (anatolii1309)]

I'll add this. That after I removed nvidia. I can now log in via recovery mode.
There is still a black screen for normal login.

[Anatoli Navahrodski (anatolii1309)]

I cannot do this as I have a black screen and nothing.
This is not available in recovery mode.

Please don't boot into recovery mode while investigating this bug. Recovery mode is not relevant to the bug.

That said, Ubuntu 20.10 reaches end of life this month so upgrading to 21.04 should probably be the next step. That will also give you kernel version 5.11 which might hopefully work better...

[Anatoli Navahrodski (anatolii1309)]

I wrote earlier that I was updating to version 21. This did not solve my problems.
How do I best update ubuntu? Through the console?

Linux ter 5.11.0-22-generic #23-Ubuntu SMP Thu Jun 17 00:34:23 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

I have updated ubuntu. This did not help the problem remained.
Also there is no brightness editing.

[Daniel van Vugt (vanvugt)]

OK, that's progress. Please open two new bugs to cover those issues:

 * Nvidia driver 460 fails in install on 21.04

 * Brightness control is missing on HP Pavilion Gaming Laptop 15-dk0xxx

Assuming the Intel GPU is wired to the laptop screen those are different bugs.

[Anatoli Navahrodski (anatolii1309)]

What should I do?

[Daniel van Vugt (vanvugt)]

Please open two new bugs by running these commands from your new 21.04 installation:

  ubuntu-bug nvidia-driver-460

and title it "Nvidia driver 460 fails in install on 21.04", and

  ubuntu-bug linux

and title it "Brightness control is missing on HP Pavilion Gaming Laptop 15-dk0xxx"
