   1 ## Chromebook Config
   2
   3 DragonFly currently supports the Acer C720 and C720p Intel-haswell chromebook.  You must follow the linux directions on how to unlock the chromebook so non-chrome OSs can be installed.  Generally speaking, the linux directions get you to a point where you can boot any kernel via the built-in SeaBIOS.  Note that you can always restore your chromebook back to using chrome by following Google's directions on recovering a chromebook.
   4
   5 On the Acer C720 you need to load specific drivers to gain support for the touchpad and touchscreen.  In "/boot/loader.conf" add:
   6
   7     ig4_load="YES"
   8     cyapa_load="YES"
   9     atmel_mxt_load="YES"
  10     if_ath_load="YES"
  11
  12 The atmel module is only needed for the touchscreen model.
  13
  14 DragonFly supports accelerated X on haswell cpus via the "intel" driver.  You no longer have to recompile the X server, the dports binaries are completely up-to-date and support it properly.
  15
  16 The "/etc/X11/xorg.conf" configuration file should consist of the following:
  17
  18     Section "ServerLayout"
  19             Identifier     "X.org Configured"
  20             Screen      1  "Screen0" 0 0

  24             InputDevice    "Keyboard0" "CoreKeyboard"
  25     EndSection
  26
  27     # This may be needed to prevent X from ignoring keyboard
  28     # and mouse devices in xorg.conf.
  29     #

 120
 121 For the touchscreen to work, you need to install the "xf86-input-elographics" driver:
 122
 123     pkg install xf86-input-elographics
 124
 125 We suggest [starting X via xdm](http://www.dragonflybsd.org/docs/newhandbook/X/#index4h3) which needs a package in addition to xorg:
 126
 127     pkg install xdm
 128
 129 For WIFI support you will want this in your "/etc/rc.conf"
 130
 131     wlans_ath0="wlan0"
 132     ifconfig_wlan0="DHCP WPA"
 133
 134 And your "/etc/wpa_supplicant.conf" file should contain entries for all the wifi basestations you can connect to.  Most typically an entry looks like this:
 135
 136     network={
 137         ssid="blahblah"
 138         psk="passwordhere"
 139     }
 140
 141 ### Volume and backlight adjustment keys
 142 In order to use these keys make two scripts:
 143
 144     #!/bin/csh
 145     #
 146     # mute script
 147
 148     set curvol = "`mixer -f /dev/mixer1 -s vol`"
 149
 150     if ( -f ~/.savemute ) then
 151             set lastvol = "`cat ~/.savemute`"
 152     else
 153             set lastvol = ""
 154     endif
 155
 156     if ( "$curvol" == "vol 0:0" ) then
 157             if ( "$lastvol" != "" ) then
 158                     eval mixer -f /dev/mixer1 $lastvol
 159             endif
 160     else
 161             if ( "$lastvol" != "$curvol" ) then
 162                     echo "$curvol" > ~/.savemute
 163             endif
 164             mixer -f /dev/mixer1 vol 0
 165     endif
 166
 167     #!/bin/csh
 168     #
 169     # backlight script
 170
 171     set level = `sysctl -n hw.backlight_level`
 172     @ level = $level + $argv
 173     sysctl hw.backlight_level=${level}
 174
 175 add next lines to `~/.xbindkeysrc`:
 176
 177     # Volume
 178     #
 179     "/path/to/scripts/mute"
 180       F8
 181
 182     "mixer -f /dev/mixer1 vol -5"
 183       F9
 184
 185     "mixer -f /dev/mixer1 vol +5"
 186       F10
 187
 188     # Screen
 189     #
 190     "/path/to/scripts/backlight -20"
 191       F6
 192
 193     "/path/to/scripts/backlight 20"
 194       F7
 195
 196 You must call xbindkeys somewhere in your `.xinitrc`.
 197
 198 *Hint:* You can set default blacklight level by placing next line in `.xinitrc`:
 199
 200     sysctl hw.backlight_level=370
 201
 202 ### Home, End, Delete, ...
 203
 204 With Alt as modifier you can get:
 205
 206 Insert    = Alt + \
 207
 208 Delete    = Alt + BackSpace
 209
 210 Home      = Alt + Left
 211
 212 End       = Alt + Right
 213
 214 PageUp    = Alt + Up
 215
 216 PageDown  = Alt + Down
 217
 218 Create dirs for keyboard configuration
 219
 220     mkdir -p ${HOME}/.config/xkb/types ${HOME}/.config/xkb/symbols
 221
 222 Create modifiers' config file `${HOME}/.config/xkb/types/c720` which contains
 223
 224     xkb_types "c720" {

 228             map[Shift]  = Level2;
 229             map[Alt]    = Level3;
 230             map[Alt+Shift]    = Level3;
 231             level_name[Level1] = "Base";
 232             level_name[Level2] = "Caps";
 233             level_name[Level3] = "Alt";
 234         };
 235     };
 236

 305
 306 Add next line to `.xinitrc` (or in some autoload/autostart)
 307
 308     setxkbmap -layout "us+c720" -types "complete+c720" -print|xkbcomp -I"$HOME/.config/xkb" - "${DISPLAY%%.*}"
