## Pre-installation notes

The M4800 comes with a legacy BIOS and UEFI. The Arch installation media, version 2014.04.01, may not properly boot or install if using legacy BIOS and/or a MS-DOS partition table. Using the UEFI option with a GPT-partitioned hard drive was required to successfully complete the installation process.

The M4800 will not give you a usable system unless `nomodeset` is added to the kernel command line. This is required for both the Arch installation media and post-installation. Because `nomodeset` is required even after booting, use of the Nouveau driver is not possible because Nouveau requires KMS.

## What does not work

- The brightness up/down buttons do not work in Cinnamon or at the virtual console without X (untested on other desktop environments).
- When Cinnamon locks the screen due to inactivity, pressing keys or moving the mouse does not automatically turn the display back on to allow unlocking the screen. A workaround is to press `Ctrl+Alt+F2` followed by `Ctrl+Alt+F1`, which switches from TTY1 to TTY2 and back again.
- Switching TTYs with `Ctrl+Alt+FX` after X has started does not present the user with a usable TTY.
- When closing the GUI (e.g. by logging out of Cinnamon), the screen goes black, and the virtual console does not appear like it should.
