  • Hardware: Intel NUC5CPYH

    Display: Dell 2405FPW 1920x1200 monitor, connected via HDMI using an HDMI-to-DVI adapter

    OS: Ubuntu 15.10

    Used Intel Graphics Installer 1.2.1 to obtain driver



    Several times a day, the display will turn all white.  The computer is still running - any music that was playing continues to play.  I can still ssh into the machine and run a shell.  If I hit CTRL-ALT-F1, it appears to switch virtual consoles, as the screen changes to all black - no text is displayed.



    Rebooting the computer fixes the problem.

    Suspending the computer & then waking it up also fixes the problem.


    Any ideas?  Is anybody else seeing this problem?

  • Hi - the driver in ubuntu 15.10 isn't upgraded by the installer, so what you're seeing sounds like a bug in the shipped driver - is there anything of note in the dmesg output when this happens? It's probably worth your while fileing a bug under the drm/intel component at for this one - the i915 developers track bugs there and this sounds like something they'd want to get on top of.

  • What exactly does the installer do?  I thought it was providing updated drivers for Intel GPUs.  My apologies for my confusion.


    I do see intel-related error messages in dmesg, so I'll include those when I file a bug.


    I couldn't find a "drm/intel" component at  Should I file it under the "Drivers/DRI/i915" component in the "Mesa" product, or is there a more approriate place?


    Thanks for your help.

  • The installer upgrades a few components, but only if they're not up to date - release their stack
    (the kernel i915 driver, mesa, libdrm and a few other libraries) quarterly, and Ubuntu (for example) releases
    every six months - but the releases aren't co-ordinated, so sometimes the distribution is up-to-date or
    ahead of the release already with respect to some components.

    For the bug try product=DRI and component DRM/Intel.

  • Hi all,


    FYI, I have the exact same issue with my Zotac ci323Nano.

    OS : Linux Mint XFCE 17.2

    Kernel 4.2.0-18-generic

    Problem appear at the end of the day, so around 10 hours after boot. Computer still work perfectly (I can log via ssh, and see that the temperature is ok), but screen stay completely white.
