Reason:
This page is missing a proper hardware and function keys table (Discuss in

This page contains instructions, tips, pointers, and links for installing and configuring Arch Linux on the Acer Aspire S7-392 Laptop.
This page only applies to the 392 model (4th Gen Intel CPU), and may not be entirely correct for the 391 or 191 models (3rd Gen Intel CPU).
Compatibility
The laptop works surprisingly well with Arch Linux, requiring minimal or no configuration hacking, depending on your desired setup.
What works?
Note
Touchscreen only works in a Window Manager or Desktop Environment that has full support for it. It is recognized as a mouse click otherwise.
Touchscreen
Screen Brightness Adjustment
Requres a window manager or desktop environment with the functionality, such as
Xfce
,
GNOME
, or
MATE
.
Alternatively, a hotkey daemon such as
acpid
may provide hotkey functionality (Not tested).
Keyboard Backlight (And adjustment)
Most Keyboard Hotkeys
Wireless Toggle may not work.
acpid
may work with it (Not tested)
Wireless Networking
What does not work, or is weird?
Touchpad Multitouch Gestures
Touchscreen stops working after waking up from suspend
BIOS Setup
The BIOS Setup utility is accessed by pressing Fn+2 at the Acer Logo screen during startup.
Disable Secure Boot
In order to install Arch on the S7 you need to disable Secure Boot from the BIOS Setup. You need to do
Security > Set Supervisor Password
to set a supervisor password. Without it the option to disable Secure boot will be grayed out. Then go to
Boot > Secure Boot
and set it to
Disabled
and remove the supervisor password (by setting an empty one).
Booting
The information in
Boot loaders
applies here. GRUB is confirmed to work.
Change Boot from UEFI to BIOS
If desired, you can optionally select whether to use BIOS or UEFI when booting. This is an option in the BIOS Setup utility.
Boot from USB
Booting from USB is possible by reordering boot devices in the BIOS setup, or by accessing the Boot Menu by pressing the "Fn" key and "=" key simultaneously (Translates to F12).
Note
The boot menu might be disabled - set
Main > F12 Boot Menu
to
Enabled
in BIOS Setup
UEFI Boot Arch
One some dual-SSD machines the disk that BIOS boots from by default is identified as
/dev/sdb
rather than
/dev/sda
. If you are running a RAID it is recommended to leave a GPT partition on both disks. If you get an error after booting that BIOS cannot find a bootable media, but drops you in the boot menu where you can select HDD and it boots from there - you have installed grub on the wrong disk.
Graphics Drivers
With the default setup, there will be graphics tearing on the S7-392. You can check the "Tear-free video" section of the
Intel graphics
page for information on fixing tearing.
Multitouch Gestures
Note
Multitouch in Touchegg has broken since writing this. It does not work now
The touchpad works well with
xf86-input-synaptics
, and with
touchegg
for advanced multitouch gestures.
Note
Contrary to what most of the internet says, you do not seem to need
xf86-input-evdev
to make Touchegg work.
Console fonts
Since some of these come with HiDPI displays the default console font is barely readable - refer to
Linux console#Fonts
on how to change them.
Wi-Fi instability
This laptop uses Intel Corporation Wireless 7260 Wi-Fi chipset. With the current firmware it might have issues connecting when signal is suboptimal. Disabling power save mode on the chip improves the connection times and connection speed. See
Wireless network configuration#Power saving
on how to disable it and make it permanent.
