XPS 13 2015 9343 (QHD) - dual boot Win8-Ubuntu15.04: screen goes blank after few seconds with linux
Hi all!
I have new a Dell XPS 13, running Win 8.1, and I have screen issues when I try to boot Linux systems (tried a few different distros, like Ubuntu 15.04, Fedora 22, ...). I've been playing around with the PC for a month now and read many forums online, but I've found no solution.
The screen goes black after a couple of seconds at the linux login window (The PC still works, only no screen), with a live USB as well. I could install Linux using an external monitor via mini display port because the external monitor works. If I set nomodeset or i915.modeset=0 in the grub kernel parameters everything seems to be working but the displayport doesn't, so no external monitor. I tried different kernels (e.g. 4.1.0-rc2), but I was unable to solve the issue and, moreover, recent kernels add flickers. Everything else is OK (touchpad works, keyboard works, volume buttons work, Wi-Fi works, ...)
I installed Ubuntu disabling secure boot and Win8 still works fine (sometimes I lose the monitor for a second, though).
Anyone with the same problem? Suggestions? Heeeeeeelp!
Thanks!
Matteo

Having the exact same issue, on my XPS 13 2015(i7/8GB/QHD/256) machine which is dual boot in win 10 and Ubuntu 15.04.The screen goes blank(black) randomly, have to press the power button and shutdown the machine and the restart again. Very frustrating issue.
Hi everyone,
I did not find any solution to the problem so far, but I worked around it.
I edited /boot/grub/grub.cfg and now I have two boot entries one with i915.modeset=0 and one without it. Using the first I can (only) use the laptop monitor, using the latter I can (only) use an external monitor via displayport. It's not perfect and the graphics with modeset=0 has problems here and there, but it's usable. I hope Dell will give us a feedback about this issue.
Any better solution? I can be more detailed about mine if needed.
Cheers,
Matteo
I've posted the exact same problem in March if I'm not mistaken. Anyway the hack around that made it work for me was to put the following in a script:
#!/bin/bash
xset dpms force off
sleep 1
xset dpms force on
And then assign a shortcut (Super+Alt+S here) to it. Whenever the screen went blank, I just have to press the shortcut.
But really ... it's embarrassing for Linux/Dell to not have fixed such a glaring but ... :(

Hi Matteo, Hi All,
i have the same hardware Dell XPS 13 (2015) QHD, i/-5500U with debian testing and kernel 4.1 and doubleboot with win 8. I also have the same problem that under linux the screen suddenly turns black and i have to push the power button to suspend and than push again to wake up and activate the screen.
i searched the usuall g.. and forum threads but did not find any solution. it seems to happen only on QHD displays.
thanks for any suggestions what i could do?
Thanks Peter
