old kernel driver still used after update tool

Hi, very strange. I have removed all packages as described here: https://01.org/linuxgraphics/forum/graphics-update-tool-discussions/how-remove-drivers-installed-intel-graphics-update-tool, then intel-graphics-update-tool itself.

Then install it again with gdebi as recommended:

sudo gdebi intel-graphics-update-tool_2.0.2_i386.deb

List of packages got from 01.org present in my system after finally launch sudo intel-graphics-update-tool:

~$ dpkg-query -f '${binary:Package}\n' -W | while read pkg; do apt-cache madison $pkg | head -n 1; done | grep -F 01.org
i915-4.6.3-4.4.0-dkms |          1 | https://download.01.org/gfx/ubuntu/16.04/main xenial/main i386 Packages
i965-va-driver | 1.7.1-0intel1
intel-gpu-tools | 1.15-1intel1
intel-graphics-update-tool |      2.0.2
libcairo-gobject2, libcairo2, libva-drm1, libva-egl1, libva-glx1, libva-tpi1, libva-wayland1, libva-x11-1, libva1, va-driver-all, vainfo

But still using original ubuntu driver as it seems:

~$ modinfo i915 | head -n 1
/lib/modules/4.4.0-87-generic/kernel/drivers/gpu/drm/i915/i915.ko
~$ lspci -kvnn | grep -i -E 'vga|i915'
00:02.0 VGA compatible controller [0300]: Intel Corporation 82852/855GM Integrated Graphics Device [8086:3582] (rev 02) (prog-if 00 [VGA controller])
    Kernel driver in use: i915
    Kernel modules: i915, intelfb
    Kernel modules: i915

No fails / warns in var/tmp/intel*.log except this one at the end:

~$ cat intel*1095.log | grep -i -e 'error' -e 'fail' -e 'warn'
diagnostics warning flags: 00
Error opening log file: Error opening file '/var/tmp/intel-graphics-update-tool-1095.log': File exists

Last lines of intel-graphics-update-tool-1095.log:

Hi Elio,

It showed 1.7.1 for i965-va-driver, not for i915

So finally I found this file: /var/lib/dkms/i915-4.6.3-4.4.0/1/4.4.0-87-generic/i686/log/make.log, which have errors:

/var/lib/dkms/i915-4.6.3-4.4.0/1/build/drivers/gpu/drm/i915/intel_audio.c: In function ‘intel_audio_codec_enable’:
/var/lib/dkms/i915-4.6.3-4.4.0/1/build/drivers/gpu/drm/i915/intel_audio.c:532:3: error: too few arguments to function ‘acomp->audio_ops->pin_eld_notify’
   acomp->audio_ops->pin_eld_notify(acomp->audio_ops->audio_ptr, (int) port);

So I simple commented these lines :)

//if (acomp && acomp->audio_ops && acomp->audio_ops->pin_eld_notify)
   //acomp->audio_ops->pin_eld_notify(acomp->audio_ops->audio_ptr, (int) port);

Then recompiled kernels with dkms I found there.

Now modinfo i915 shows proper new location:

Is any tweaks for this driver to specify color depth, or any perfomance related settings?

I trying to setup simple web-browsing 'terminal' from old notebook. I installed Ubuntu server minimal as possible, then x-windows packages, Awesome as windows manager.

Mmm.. good question, honestly the only thing that i have on mind right now should be firmwares as DMC, GuC and HuC in order to increase performance in your GPU execution units, please go to the download section and check if your system is candidate to this firmware. Thanks for your comments!
