Lightdm is just a black screen when booting kernel 5.3 on an i5-6500, but kernels 5.0/5.2 work

[Claudio Fior]

Xorg freeze at boot on Intel Corporation HD Graphics 530 with linux-image-5.3.0-17 after upgraded to the development release Ubuntu Eoan Ermine (development branch).
If i boot with linux-image-5.0.0-31-generic the Xorg works well.

[Daniel van Vugt (vanvugt)]

What do you see during the freeze? Is it a black screen or something else?

Does the machine even boot kernel 5.3 successfully?

[Claudio Fior (caiofior)]

Every time i boot with kernel 5.3 I can see the services loaded (I disable splash screen), the screen is black when requiring the user credentials.
I switch to tty1 and the pc runs well, the I reboot to kernel 5.0.
With kernel 5.0 everything is good.

At least I was able to start the pc with kernel 5.3 using nomodeset kernel option.

I added the system logs.

The second screen has not benn detected

[Daniel van Vugt (vanvugt)]

Can you please attach a photo of the original problem (the black screen) without using nomodeset?

Please also log in to the text console there and record the kernel log:

  dmesg > blackscreendmesg.txt

Then attach the file 'blackscreendmesg.txt' to this bug.

We would like to see photos and logs from the 5.3 kernel trying to boot without nomodeset.

[Claudio Fior (caiofior)]

black screen

[Claudio Fior (caiofior)]

Datail of black screen

[Claudio Fior (caiofior)]

Black screen log

[Daniel van Vugt (vanvugt)]

Thanks!

[Daniel van Vugt (vanvugt)]

Oops, I missed the part where you said that booting works. Only the login screen is missing:

Every time i boot with kernel 5.3 I can see the services loaded (I disable splash screen), the screen is black when requiring the user credentials.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This change was made by a bot.

[Claudio Fior (caiofior)]

I did some test, with kernel 5.2.21 everything works (linux-image-unsigned-5.2.21-050221-generic_5.2.21-050221.201910111731_amd64.deb).

I also tried kernel 5.3.6 and the screen is again black at boot (linux-headers-5.3.6-050306_5.3.6-050306.201910111731_all.deb)

[Kai-Heng Feng (kaihengfeng)]

Would it be possible for you to do a kernel bisection?

First, find the last good -rc kernel and the first bad -rc kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/

Then,
$ sudo apt build-dep linux
$ git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
$ cd linux
$ git bisect start
$ git bisect good $(the good version you found)
$ git bisect bad $(the bad version found)
$ make localmodconfig
$ make -j`nproc` deb-pkg
Install the newly built kernel, then reboot with it.
If the issue still happens,
$ git bisect bad
Otherwise,
$ git bisect good
Repeat to "make -j`nproc` deb-pkg" until you find the commit that causes the regression.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Timo Aaltonen (tjaalton)]

and test newer mainline kernels
https://kernel.ubuntu.com/~kernel-ppa/mainline/

try 5.4-rc4 and if it doesn't work, drm-tip

[Timo Aaltonen (tjaalton)]

the kernel driver seems perfectly happy though.. could you change to tty1 and copy /var/log/Xorg.0.log somewhere and then attach here

[Claudio Fior (caiofior)]

The video works with kernel 5.4-rc4 form https://kernel.ubuntu.com/~kernel-ppa/mainline/.

Thank you for your patience.

[Timo Aaltonen (tjaalton)]

great, then try 5.4-rc1 hoping that it's broken there, then a fix would be fairly easy to spot

[Claudio Fior (caiofior)]

Fixed also on 5.4-rc1 and 5.3.8

[Timo Aaltonen (tjaalton)]

if 5.3.8 works then 5.3.0-24.26 from eoan-proposed should work as well, could you check?

[Timo Aaltonen (tjaalton)]

assuming fixed since 5.3.8 worked
