X server goes black

[exoit]

Hi,

I have the XPS 13 9343 with the QHD screen and when X starts the screen sometimes just go black. When the screen goes black a reboot sometimes resolves it. If I login while the screen is black and run "xset dpms force off" the screen wakes up and works again.

Has anyone else experienced this issue and found a solution?

yes. fn+f12 (brightness) solves for me :)

I can see that the screen backlight goes darker and brighter when pressing
fn + F11/F12. But the screen is still black i.e. X is not showing anything.

Unfortunately, I have already seen that forum post and know that you can
wake up the screen with the "xset dpms" commands. That is however not a
permanent fix for the issue. I also tried making a start up script for when
the X server started that would always run xset dpms force off; sleep 1;
xset dpms force and other variants but the issue still persist.

Of course i know you have already read it. just information for members of this thread:)
By the way I'm using Gentoo and seeing this wiki.

Gentoo Wiki: https://wiki.gentoo.org/wiki/Dell_XPS_13_9343#Display_Blanking_randomly

And I think my 9343 with QHD+ screen behavior may be more stable in a few days... I'd like to share you what I did. I hope it is useful for guys who have the same problem.

1. update Mesa to 11.0.0_rc1
2. install xf86-video-intel to latest in git repository(now using git 3e07681c1948db240b29928bb1e129e559733537 revision)
3. update braodcom-sta to 6.30.223.248-r4

Of course they may not be related to this problem, just information.

Here is another info about my environment:

kernel: gentoo-sources-4.1.6
xorg: xorg-server 1.7.2-r1
KDE Plasma 5 latest git branch (daily building)
Qt: 5.6 branch

@kenya888 Did the screen issue get resolved for you with the xf86-video-intel & Mesa you built?

[kenya888]

@exoit No. it isn't gone completely.

Adding i915.modeset=0 to the boot parameters seems to resolve it, but the graphic acceleration performance takes a huge hit from it.

I might have found a solution for this, after I installed the kernel and bcmwl from the links below I have not been able to reproduce the issue.

Ubuntu 15.04
Kernel http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-nightly/2015-09-08-unstable
Bcmwl https://github.com/longsleep/bcmwl-ubuntu

I have not been able to reproduce the issue after updating to the Kernel in my previous comment.
