  • Hello

     

    I bought a laptop with intel hd4600 card. My choice was guided by the given I had read that the intel drivers are open- source Linux . So I installed kubuntu 13.10 on it without problem . I soon found that the driver was installed free ( i915 ) .

    Wanting to try the proprietary driver provided on the intel with the graphical installer 1.0.3 website , I encountered a bug in ubuntu 13.10 and control

    update- initramfs -u
    [ sudo ] password for michel :
    update- initramfs : Generating / boot/initrd.img-3.11.0-15-generic
    / usr / share / initramfs -tools / hooks / intel_microcode : 136 : / usr / share / initramfs -tools / hooks / intel_microcode : prepend_earlyinitramfs : not found
    E : intel - microcode : failed to prepend early firmware to initramfs
    W : intel - microcode : will try to use late initramfs update mode.

    Hoping Ubuntu fixes this problem soon enough for the installation ends well ( taking into account kms_intel )

    Now what was my disappointment to find , unless I am mistaken , the proprietary drivers ( or free ) are not provided with a graphical interface for managing map settings ( power , frequency) as does NVIDEA or ati . I hope that my choice to turn to intel was good ?

     

    Thank You

  • AFAIK, these are not "propietary drivers", but "updated drivers": this is the "Intel Open Source Technology Center", and there are links to download the source code used to build the binary packages; these drivers are intended to update those provided by your distribution.

  • You are correct: The installer provoides a way of getting the latest drivers and userspace libraries
    from the upstream project(s) in question on the target distributions, which are (understandably)
    generally carrying slightly older versions. No proprietary code or binary blobs here, we're trying
    to be good citizens.

  • I changed the command line in grub like this, after reading here and there on sites, comments

     

    pcie_aspm=force acpi_osi=Linux acpi=force acpi_enforce_resources=lax i915.i915_enable_rc6=1 i915.i915_enable_fbc=1 i915.lvds_downclock=1 i915.semaphores=1 drm.vblankoffdelay=1 acpi_backlight=vendor

     

    If these lines are really useful, it would be interesting to have a graphical utility for managing

  • Hey micmor - 

    Just wanted to let you know that your parameters solved a major issue I had on my Lenovo Edge E330 which happened both on Ubuntu 13.10 and Ubuntu 14.04.

    The computer used to restart again and again before booting up properly. In most cases it would simply shut down in the middle of the startup sequence. The only way for me to guarantee it would start up properly was to to use the "nomodeset" mode. Otherwise I had to let it reboot again and again and wait for a successful attempt.

    Thanks to you I modified the following line in the "/etc/default/grub" file:

     

    GRUB_CMDLINE_LINUX_DEFAULT="pcie_aspm=force acpi_osi=Linux acpi=force acpi_enforce_resources=lax i915.i915_enable_rc6=1 i915.i915_enable_fbc=1 i915.lvds_downclock=1 i915.semaphores=1 drm.vblankoffdelay=1 acpi_backlight=vendor"

     

    I then ran:

    sudo update-grub

     

    And from that moment on - problem's solved!

     

    I'm posting this in case other users encounter a similar problem.
