8086:0a16 [ASUS Zenbook UX302LG] Black screen on boot

[Joel Wirāmu Pauling (aenertia)]

Install via LiveUSB created with unetbootin off the saucy amd64 iso was able to be completed with "nomodeset". First boot into installed system resulted in lightdm "cowbell" being played but a backlight on / blank screen on the display. using nomodeset on installed system results in framebuffer/console being usable - but no X able to start (cannot find screen). tried some alternative kernel options : acpi_backlight=vendor, video=1920x1080-24@60 but with same results. Tried using different kernel as per bug https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1195483 . pinned and upgraded to trusty kernel images - slightly different result in that backlight goes down and breifly have a red screen tear in upper left of screen for several seconds before reverting to same behaviour as saucy kernel. (blanked screen, backlit, lightdm cowbell plays).

WORKAROUND: Upstream drm-intel-next build resulted in working lightdm/screen:

Joel Wiramu Pauling, thank you for reporting this bug and helping make Ubuntu better. Given you found a WORKAROUND in the upstream drm-intel-next build, would you be able to reverse bisect to find the commit that fixed your problem following https://wiki.ubuntu.com/Kernel/KernelBisection ?

[Joel Wirāmu Pauling (aenertia) (aenertia)]

Unfortunately whilst I get the screen up on boot, the first time the screen is blanked either by power management, or switching a VT or standby(closing lid) - I "loose" the screen and need to do a reboot to get it back. Not very useful unfortunately.

I have tried a couple of different 3.12 kernels mainline and zen patches - neither work (original behaviour, no screen at all).

Going to try a mainline 3.13 kernel today and see if it behaves the same as the drm-intel-next

[tehownt (tehownt)]

I have the exact same issue with the laptop...

Tried the mainline kernel at http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13-rc6-trusty/ but the behaviour was the same as with 3.12 : black screen on boot.

Had to revert to 3.13 drm-intel-next and it worked OK except when screen is dimmed the laptop is lost and you need to reboot.

Also tried installing nvidia-331 but to no avail, black screen on boot but sortof cycling between on/off.

[Emmanuel (eprochasson)]

Might be helpful or not, thought I'd just drop it here.

After installation of a fresh Ubuntu 13.10 with Secure Boot (and with CSM Disabled in the BIOS), using an internet connection to get updated packages, booting with nomodeset and installing nvidia-prime, I find that X/lightdm works pretty well. I can even activate desktop effects and the whole thing runs very smoothly. However, many features are broken (can't get an extra screen plugged in, can't suspend to RAM/Disk).

Not sure that's relevant information, but it can't hurt.

[penalvch (penalvch)]

Emmanuel, thank you for your comment. So your hardware and problem may be tracked, could you please file a new report with Ubuntu by executing the following in a terminal while booted into a Ubuntu repository kernel (not a mainline one) via:
ubuntu-bug linux

For more on this, please read the official Ubuntu documentation:

Thank you for your understanding.

Just tried the workaround proposed here (use drm-intel-nightly kernel, removed nvidia-prime, and remove "nomodeset" from grub options) and it works just as good, probably a bit better: I can plug-in an external screen, though I lost the main screen if I am to unplug/deactivate the external screen. Suspend seems to fail just as before (blank screen, yet functioning system on resume). I assume those two issues are for another bug report anyway.

Note to @penalvch: the previous comment was another workaround for this bug that worked for me, not another bug report. Do you still want me to fill in a new report?

[penalvch (penalvch)]

Emmanuel, yes.

I'm seeing this issue on a fresh 14.04 install. However, unlike 13.10, using "nomodeset" and the generic SVGA X drivers seem to work enough to start the display at its native resolution.

As you can see, the Intel driver isn't being loaded at all on my ux302lg:

# lshw -c video
  *-display UNCLAIMED
       description: VGA compatible controller
       product: Haswell-ULT Integrated Graphics Controller
       vendor: Intel Corporation
       physical id: 2
       bus info: pci@0000:00:02.0
       version: 09
       width: 64 bits
       clock: 33MHz
       capabilities: msi pm vga_controller bus_master cap_list
       configuration: latency=0
       resources: memory:f7400000-f77fffff memory:d0000000-dfffffff ioport:f000(size=64)

I'm going to attempt to install the intel-drm-next kernel, and will report back once I've done so.

[Tessa (unit3)]

Using the following intel-drm-next kernel, along with removing "nomodeset" from my boot options, has allowed me to get the intel driver working, like others have reported:

http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-next/current/linux-image-3.14.0-997-generic_3.14.0-997.201404170342_amd64.deb

As well, the nvidia card seems to function correctly with bumblebee, even with the intel-drm-next kernel. So hopefully we'll see a backport of a newer kernel with these fixes into 14.04 at some point, perhaps for 14.0.4.1?
