+===== 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
+# cat brightness
+# 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.
