Network

Ethernet : RTL8111/8168B PCI Express Gigabit Ethernet controller

module: r8169 in kernel

Wifi : Broadcom Corporation BCM4322 802.11a/b/g/n

VGA

Follow instructions in the ATI wiki page.

SmartCard Reader

works out of the box. just having minor privledge issues atm

Webcam

works. followed setup as in Webcam tested using:

$ mplayer tv:// -vf screenshot

Modem

Not tested yet. Chances are you probably will not need this. Add some info if you find out how to set this up!

Keyboard

almost all Fn keys work out of the box.

• rotate screen button and configuration button are not recognized by xev
• Fn + F[1-4] are bound as:

$ xev | grep -A2 --line-buffered '^KeyRelease' | sed -n '/keycode /s/^.*keycode \([0-9]*\).* (.*, \(.*\)).*$/\1 \2/p'
146 Help         <- Fn+F1
33 p             <- Fn+F2*
37 Control_L     <- Fn+F2* (Fn+F2 performs both functions simultaneously)
180 XF86HomePage <- Fn+F3
33 p             <- Fn+F4

Touchpad

• mouse input = works
• scrollup/down = works
• tap to click = works
• mouse buttons = work

Stylus

• mouse input = need to modify xorg to work
• button (right click) = need to modify xorg to work
• tap to click = need to modify xorg to work

Remote

• Works by default: Super (Windows Button), Squiggly (turns screen brightness down), Arrow keys (behave like the ones on the keyboard), volume controls.
• Does not work by default: Power, DVD, Play, Stop, Forward, Backward, previous, next, up, info, ok?
• Update coming soon. ;) Trusktr 03:07, 2 May 2011 (EDT)
