 +===== Notes =====
 +Tested with Debian Testing (v8), Linux Kernel 3.14-2-amd64 and 3.16-3-amd64 ​
 +
 +===== How to disable Secure Boot =====
 +Enter BIOS (really UEFI) settings by pressing F2 when the "​Acer"​ splash screen appears. (Also, note that the boot menu can be accessed by pressing F12 at the "​Acer"​ splash screen.)
 +
 +Initially, the option to disable secure boot will be greyed out and unchangeable. However, if you setup a BIOS password, *then* it will let you disable secure boot. (Don't worry, you won't have to enter the BIOS password just to boot, only to get back into BIOS setup.) There'​s no need to switch to Legacy boot.
 +
 +If you want to install Linux (even if you still want to dual-boot Windows), you'll probably also want to adjust the boot order and move "​Windows"​ all the way to the last. Linux'​s bootloader can boot the pre-packaged Windows 8.1 just fine, so this is ok.
 +
 +===== Screen Brightness =====
 +In kernel 3.16 (available in Debian testing/​unstable),​ the screen brightness controls work fine, including the built-in keyboard'​s brightness controls.
 +
 +On the older kernel 2.14, the screen brightness controls have no effect (they adjust "/​sys/​class/​backlight/​acpi_video0/​brightness"​ which does nothing). However, the screen brightness can be changed manually on the command line by reading/​writing "/​sys/​class/​backlight/​intel_backlight/​brightness"​. To do this, log in as root (doing it with sudo doesn'​t appear to work even when sudo is properly set up and working, you need to "su root" for this):
 +
 +$ su root
 +# cd /​sys/​class/​backlight/​intel_backlight
 +# cat max_brightness
 +937
 +# cat brightness
 +937
 +# echo 400 > brightness
 +# exit
 +
 +===== Summary =====
 +Debian v7.6 could install ok, but upon boot the GUI would fail to run (it gets to a blank screen with a blinking cursor and stops). Upgrading to Debian testing (via command-line on Ctrl-Alt-F1) which, at the time, came with kernel 3.14 fixed the issue. Later, when Debian testing updated to kernel 3.16, hardware compatability for screen brightness and webcam was improved.
 +
 +Bluetooth doesn'​t work, not even in kernel 3.16. Everything else seems to work fine.
