  • Hi,
    I upgraded to to Graphics Installer 1.0.6 on my Ubuntu 14.04 and installed the drivers. The laptop is Intel Ivybridge powered with Intel HD graphics. However, it installs the package i915-3.15-3.13-dkms.deb which causes a bunch of error messages when I boot. Here are the relevant errors from dmesg when I boot:
    [    7.206151] drm: module verification failed: signature and/or  required key missing - tainting kernel
    [    7.208045] drm: module has bad taint, not creating trace events

    What could the problem be and will it affect performance? I tried to remove the package and the errors went away.

  • I have same issue after upgrading the driver on my Dell D630 with the 965GM chip set. error at boot that the intel module is "tainted"?  Also, screen is now so dim it is very had to see. Have to dock the laptop then undock for the screen to be bright again!


    How does one remove and reinstall the intel driver? Tried running the installer again but it doesn't change anything...

  • drm: module has bad taint, not creating trace events
    i915: module has bad taint, not creating trace events

    Sometimes marked in yellow and sometimes marked in white color...

    I dont experiment any issue, only that messages.
    Im using intel hd 2000 with my Pentium B980.

    Using an external vga monitor, works well my external and the integrated monitor.
    And not perfformance affected...

    How i can "occult" that messages?

  • Got the same errors while booting:

    drm: module has bad taint, not creating trace events
    i915: module has bad taint, not creating trace events

    This caused a blackscreen. After forcing shutdown and then another attempt to boot it worked. I am running a:

    • Intel® Core™ i7-2640M CPU @ 2.80GHz × 4
    • Intel® Sandybridge Mobile

    (Nvidia Optimus GPU disabled in BIOS)

    After upgrading to Ubuntu 14.04 from 12.04 I have had nothing but problems with the graphic drivers. Trying out various configurations with various PPA's: x-swat and edge-xorgers. None of these worked and I reverted to using the Intel CPU graphics drivers. Current state of graphics: resizing VLC videos doesn't work properly, solitaire cards are easily distorted if moved too fast and various big images shown with Javascript are distorted.

  • I have the same issue... When booting (I tried in Ubuntu 14.04 and Xubuntu 14.049 I get always theses errors:

    drm: module has bad taint, not creating trace events
    i915: module has bad taint, not creating trace events

    First marked in white color and then in white color.


    This happens since the 1.0.6 update... Until the 1.0.5 I never got theses error messages.

    Any fixes for anytime soon?


    Best regards

  • You can remove the updated driver by uninstalling the i915-dkms package (apt-get remove …) and then rebooting when it's done (the reboot is to make sure the old driver gets loaded).

    With regards to driver configuration, these guys:

    Seem to have had some success with altered kernel command line parameters.
    If you have the time, it would be interesting to know if any of those parameters address your

  • Ever there will be an update to correct this problem?

  • Yes, I removed the i915-dkms and that solved my problem. Now I can boot without the need to connect the HDMI port. :)

  • For those that may not be too technical and are not sure how to remove the i915-dkms driver and are using ubuntu or a distro that is based on ubuntu that uses the "software Center", just do a search in Software Center for "i915" without the quotes and it should show up, just click "Remove".


    After rebooting, it should be back to the original driver.

  • For the record, as far as I can tell, the "bad taint" messages are because of this:

    Short version: The kernel (prior to 3.15) is conflating "unsigned" (which our module is)
    with "force-loaded" (which it is not). I have not found a way around this.

    I still don't know how or why that would cause your HDMI problems though: I suspect
    the bad taint is just a red herring there - all it should do is disable tracing.
