1. Brightness control
/etc/default/grub

then change

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""

to

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor"
GRUB_CMDLINE_LINUX="acpi_osi=Linux"


To default set the brightness control at boot
gksudo gedit /etc/rc.local

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
echo 85 > /sys/class/backlight/intel_backlight/brightness
exit 0

Replace 85 with your requirement of brightness level

insmod tg3.ko fails. Either file is corrupt or its not compatible with the kernel update above.

[jeremy31]

There is no src folder after tar command. The folder simply does not exist and I cannot commit to a make. Any solution for this problem?

Is there a /src folder in the extracted files?

[marc13]

I solved it. The /src folder was not there, the folder layot was different, but the approach is similar.
