Toshiba Satellite R830
Wi-Fi & Ethernet
Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01) and Intel Corporation 82579V Gigabit Ethernet with kernel 3.8 work out of the box.
xbacklight fromworks fine.
Brightness control after Suspend and resume
Brightness control works until sleep but after resume it does not.
In the past, adding
acpi_osi=Linux acpi_backlight=vendor to kernel-line (see Kernel Parameters) helped me.
A better solution that works on all DEs I've tested (XFCE,Gnome, Cinnamon) is using the
video.disable_backlight_sysfs_if=1 kernel paramater. This should not be combined with the previously-mentioned kernel parameters.
There is another solution here: https://bbs.archlinux.org/viewtopic.php?id=132044
Another possibility is using a custom xorg configuration file. (Ignored by Gnome 3.16+)
In a terminal type:
sudo touch /usr/share/X11/xorg.conf.d/20-intel.conf
Now edit this file:
sudo xdg-open /usr/share/X11/xorg.conf.d/20-intel.conf
Type the following code:
Section "Device" Identifier "card0" Driver "intel" Option "Backlight" "intel_backlight" BusID "PCI:0:2:0" EndSection
Save the file; log out and in again.
