Dell Latitude 5490/5590 BIOS update 1.1.9 causes black screen at boot

[Laszlo Valko]

== SRU Justification ==
This bug causes a Dell Latitude 5490/5590 with BIOS update 1.1.9 to get a
black screen at boot. Specifying 'nomodeset' on the kernel command line works
around the problem.

Intel resolved the problem in upstream commit a3520b8992e5. This commit
is now in mainline as of 4.17.rc2. It has also been cc'd to upstream
stable.

== Fix ==
a3520b8992e5 ("drm/i915/bios: filter out invalid DDC pins from VBT child devices")

== Regression Potential ==
Low. This commit was also cc'd to upstream stable, so it recieved
additional upstream review.

Description: Ubuntu 16.04.4 LTS
Release: 16.04

Ubuntu 16.04.4 LTS was installed to some Dell Latitude 5490 & 5590 laptops, originally running BIOS version 1.0.8. The install media and the installed OS was running linux-generic-hwe kernel 4.13.0.

After upgrading BIOS to latest version 1.1.9, the kernel no longer boots: right after loading the i915 drm driver, the screen goes black, and the machine can only be reset or power cycled. This is true for both the installation media, and the OS instance previously installed to the disk and updated to the latest hwe kernel 4.13.0-38.

Specifying 'nomodeset' on the kernel command line works around the problem by disabling the i915 drm driver functionality. In that case, several display driver function are obviously missing (eg GLX & xrandr).

The problem manifested itself even when using the drm upstream latest git-head version. A custom built kernel was used to provide logs for this upstream bug report:
https://bugs.freedesktop.org/show_bug.cgi?id=105549

The upstream Intel developers provided a patch, which was successfully tested by both the original reporter and me.
https://patchwork.freedesktop.org/patch/216371/
https://github.com/freedesktop/drm-tip/commit/f212bf9abe5de9f938fecea7df07046e74052dde

I backported this fix to ubuntu-xenial hwe git-head, and tested the result successfully. I'd like this fix to be added to the ubuntu-xenial linux-generic-hwe kernel.

I built Artful and Bionic test kernels with commit f212bf9abe5de9f938fecea7df07046e74052dde. The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1764194/artful
http://kernel.ubuntu.com/~jsalisbury/lp1764194/bionic

Can you test this kernel and see if it resolves this bug?

Note, to test this kernel, you need to install both the linux-image and linux-image-extra .deb packages.

Thanks in advance!

[Laszlo Valko (valko)]

I tested them, both Artful & Bionic, and both work okay without nomodeset on my Latitude 5590.

[Jeroen Evens (loggfreak)]

any way to fix it for regular users (without compiling a kernel)
nomodeset works, but i can't use my external display if i use it

[Jeroen Evens (loggfreak)]

will this also be fixed in xenial?

[Kai-Heng Feng (kaihengfeng)]

Do you have this issue on v4.4 kernel?

[Laszlo Valko (valko)]

The issue is on v4.13 HWE kernel, because that's the only one that is actually useful at all on these laptops (for example the Intel 8265 wifi is not supported by the old iwlwifi driver in v4.4).

[Kai-Heng Feng (kaihengfeng)]

Then the kernel will land in Xenial soon.

[Jeroen Evens (loggfreak)]

i'm also on the 4.13 kernel on xenial
thanks for fixing the issue!
it's really important for me cause i really need my external monitor to be more productive at work
can't wait for the xenial kernel update to drop

[Claudio Castelpietra (clixclix)]

Sorry, how can I undo the "fix released" status?

[Claudio Castelpietra (clixclix)]

Hi everybody.
I have Ubuntu 18.04 in dual-boot with Windows 10.
With Windows, I downloaded and executed/installed Bios version 1.2.3 from Dell support site.
Now Ubuntu 18.04 is back to work.
I hope this helps someone.

[Jeroen Evens (loggfreak)]

i really don't understand why they allow anyone to update the status in launchpad, it only creates confusion, especially when you can't revert accidental changes :(
maybe @joseph salisbury can reopen this

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-bionic' to 'verification-done-bionic'. If the problem still exists, change the tag 'verification-needed-bionic' to 'verification-failed-bionic'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

[Jeroen Evens (loggfreak)]

What about Xenial?!!

[Joseph Salisbury (jsalisbury)]

Does this bug affect the 4.4 kernel? It was not mentioned in the bug report.

The fix that goes into Artful, will also be in the 4.13 based Xenial HWE kernel.

[Jeroen Evens (loggfreak)]

can confirm after updating ubuntu Xenial and removing nomodeset from boot options, everything seems to work again :)

[Laszlo Valko (valko)]

I have tested both artful-proposed (4.13.0-44-generic #49-Ubuntu SMP Thu May 24 09:57:43 UTC 2018 x86_64) and bionic-proposed (4.15.0-23-generic #25-Ubuntu SMP Wed May 23 18:02:16 UTC 2018 x86_64) kernels, and they behave correctly on my Latitude 5590.

[Igor Shuvalov (i-s-shuvalov)]

bionic-proposed (4.15.0-23-generic #25-Ubuntu SMP Wed May 23 18:02:16 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux) is OK on my Latitude 5590.
Thanks
