XPS 13 2015 9343 (QHD) with Ubuntu 15.04: screen goes blank at random times

Jared,

Is there a view from Dell whether this is a hardware issue or not? I have been having this issue in all kernels I tried (3.16 and up), but was nonetheless assuming it was a software issue. But its hard to understand if for some QHD users, there is no problem, while for others there is. Have there been any hardware revisions for the 2015 edition?

Jared, Is there a view from Dell whether this is a hardware issue or not? I have been having this issue in all kernels I tried (3.16 and up), but was nonetheless assuming it was a software issue.

To the best of my knowledge, there's no such view here on this being a hardware issue. By the way, have you been in touch with our support people? The more people seeing this issue who have open support tickets with ProSupport, the easier it'll be to have the information we need to resolve this.

same here,

also thanks for the dkms script!

using ubuntu 14.04 with cinnamon on ot

4.2.0 still has the problem also.

Yesterday it happened a couple of times. But my impression is that it happens far less often.

The workaround described above does work but is inconsistent. I sometimes have to use it more than once.

The black screen is definitely random.

So far I have done everything described in this http://mclements.net/Mike/mrc-blog/blog-150605.html

I have not done one thing but am still getting the blank screen.

Dell just announced that they are staffing up to support the community. Hopefully they get their act together and solve this.

 Hi folks,

I ve got the same problem. My dell xps 13 has the QHD display and a nativ dell ubuntu version installed. As already describe the display goes randomly off. All programms seems to run because e.g. rhythembox still plays music. A workaround that helps me is to close the laptop and open it again. The display turns on and all running  programms apear.

My bios:

adam@adam-laptop:~$ sudo dmidecode -s bios-version
[sudo] password for adam:
A05

My kernel: 

adam@adam-laptop:~$ uname -a
Linux adam-laptop 3.13.0-63-generic #103-Ubuntu SMP Fri Aug 14 21:42:59 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
adam@adam-laptop:~$

And as suggested the service tag number: 917657737

best regards
Adam L.

I'm also having the same issue.  The screen randomly going black on Fedora 22.  Everything remains running.  I can get the display working by suspending once I resume it it goes back to normal.  I have made it days with out it happening other times it will happens 5 times nearly back to back.  It usually happens several times a day.

4.1.7-200.fc22.x86_64 #1 SMP Mon Sep 14 20:19:24 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

I still have this problem in Ubuntu 15.04 and Arch Linux. I also tried Linux 4.3 release candidates to no avail. 

I'm seeing exactly the same thing on Fedora 22 (albeit with a slightly newer kernel)

Linux localhost.localdomain 4.1.10-200.fc22.x86_64 #1 SMP Mon Oct 5 14:22:49 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

Does anyone know if this is something that will be addressed in the upcoming bios A06 as it's getting beyond annoying?

This seems to be the related bug in launchpad bugs.launchpad.net/.../1500387

I opened a new bug on this on launchpad because the last one didn't seem to be quite the same issue.

bugs.launchpad.net/.../1507073

It would be helpful if anyone who is having this issue could login to launchpad and report they are affected by this bug.

Thanks

Just writing to confirm the issue. Also a QHD+ touch display, running arch kernel 4.2.3. I also get the BOGUS ALIGNMENT messages in dmesg.

A fix would be greatly appreciated, the hotkey trick at least makes my laptop usable, but definitely not a machine I'd recommend to other people.

I also have this issue with an XPS-13 9343 Developer Edition running stock Ubuntu 14.04 NOT with the QHD screen.

The xset hot hockey temporary fix doesn't work for me (it runs the xset commands to intentionally blank then unblank the screen) but if the screen blanked randomly then the script won't unblank the screen.

Its very annoying, a couple of time a day, and I have to reboot.

I can confirm that this is also an issue with the 9350 xps13 with QHD+ display. My screen is black at boot on the new 4.3 kernel, but after a suspend, it does begin to work.

Hey Adam, I may try out that drm-intel 4.3.0-994 kernel tonight and report back whether that helps out on the 9350. Thanks for opening that bug report.

Hi,

I had the same problem but the latest 4.4 kernel seems to fix it. Simply install it from

Mainline kernel ppa (linux-headers-4.4.0-040400rc2-generic_4.4.0-040400rc2.201511231054_amd64.deb, linux-headers-4.4.0-040400rc2_4.4.0-040400rc2.201511231054_all.deb, linux-image-4.4.0-040400rc2-generic_4.4.0-040400rc2.201511231054_amd64.deb)

I'm now getting a short flickering - roughly as often as the former blanking.
