Xrandr -output eDP-1 -brightness '$(luminance)' New_brightness='$(bc -l <<< 'scale = 2 $level / $factor')' Read -r level < '$path'/actual_brightness Until brightness control is supported by the kernel, we can use the following script to read off the brightness values from sysfs and apply xrandr brightness reduction to it: The following command can be used to set the brightness to 50%. The screen blanking feature also does not work. With gnome, the brightness control keys toggles the on-screen display, but it does not change the brightness level. Refer to Dell XPS 13 (9360)#Power saving for additional information on each of them.

If that does not work try this tool specifically made for Alienware 13 R3 alieneffects-13r3Īlso for the Alienware 13 R3 Intel powersaving options We can simply add the commands to the energy admin or the startup to make keyboard lights change automatically. To register it as a command and can use this program without being root we can do the next: In case of a compilation error similar to 'FILE is not defined', try adding a stdio.h include to the following: There plenty of programs like pyAlienFX or Alienware-KBL and none of these worked for me, but there is a github project that consists on sending data to USB using libusb that worked fine. To get access to the keyboard lights they can be controlling by sending data to the correct usb.īus 002 Device 003: ID 187c:0527 Alienware Corporation It is to be noted that some alienware laptop (AlienWare 13 R3) shows this issue where lspci / startx / any command hangs and freeze the system when probing inactive discrete nvidia gpu. The utility is able to turn on and off the dedicated graphics card ondemand and without having to restart the computer or reopening session. To have switchable graphics see bumblebee instructions. The following kernel error seems to be harmless.ģc:00.0 Ethernet controller: Qualcomm Atheros Killer E2400 Gigabit Ethernet Controller (rev 10)ģd:00.0 Network controller: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter (rev 32) # echo 'options ath10k_core skip_otp=y' | tee -a /etc/modprobe.d/nfĪfter a reboot, wireless should work, including wifi-ac speeds.įor Alienware 13 R3, the wifi works out of box.

In the meantime you can add the following to your kernel commandline at boot: acpi_osi=! acpi_osi='Windows 2009' There are kernel bug and bumblebee bug open to track this issue. The Kaby lake R3 suffers from a X lockup when either trying to start X or running lspci when the discrete GPU is off. Try to erase all default parameters and use only nomodeset. If this happens, we must change the kernel parameters to get ArchLinux to boot. The first issue that we can find is that the distribution does not boot but gets stuck into a nouveau loop or a black screen.
