Preparation and installation
Before booting for the first time, press F2 to enter the BIOS setup and make a note of which version you have. If necessary, upgrade your BIOS as there are some bugs in older versions which may affect the WLAN on/off button and other components.
The X20 comes with Windows XP preinstalled. Its hard drive partition must be shrunk in order to make room for GNU/Linux.
SuSE 9.3 was installed via network through my company's LAN. Except for the X.org display setup, installation went off without a hitch.
SuSE's X configuration utility, SaX, had trouble setting up the graphics card and display. I had to use the default /etc/X11/X.org file produced during installation. This gave me a respectable display of 1280×1024 at 24 bpp.
To achieve the maximum LCD resolution of 1400×1050, you need to make several changes to the system. First, download and install 915resolution and add the following line to /etc/init.d/boot.local:
915resolution 5c 1400 1050
You may need to obtain the latest i810 driver; be sure you download the one appropriate for your version of X.Org. Install the driver in /usr/X11R6/lib/modules/drivers. The i810 driver that comes with SuSE 9.3 does not support 1400×1050 mode; I'm not sure about later versions of SuSE.
Finally, modify the relevant sections of your /etc/X11/xorg.conf file to read as follows:
Section "Module" Load "dbe" Load "dri" Load "extmod" Load "glx" Load "freetype" EndSection Section "Monitor" Identifier "LaptopLCD" Option "DPMS" DisplaySize 304 228 EndSection Section "Device" Identifier "i915Chipset" Driver "i810" BusID "PCI:0:2:0" VideoRam 131072 Option "NoAccel" "false" Option "DRI" "true" EndSection Section "Screen" Identifier "LaptopScreen" Device "i915Chipset" Monitor "LaptopLCD" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 8 EndSubSection SubSection "Display" Viewport 0 0 Depth 16 EndSubSection SubSection "Display" Viewport 0 0 Depth 24 EndSubSection EndSection Section "ServerLayout" … Screen 0 "LaptopScreen" 0 0 … EndSection Section "DRI" Group "video" Mode 0660 EndSection
The following hotkeys work out of the box:
- adjust LCD brightness
- toggle LCD/external monitor
- toggle S/PDIF
- toggle 3D sound
- toggle "Etiquette mode"
- toggle touchpad
- touchpad middle button
- toggle touchpad
- WLAN button
- toggle WLAN
To get Fn-F6 (mute), Fn-Left (volume down), and Fn-Right (volume up) to work, put the following in /etc/X11/Xmodmap:
keycode 174 = XF86AudioLowerVolume keycode 176 = XF86AudioRaiseVolume keycode 160 = XF86AudioMute
If you are using KDE and the package `kdeutils3-laptop' is installed, then you will get nice popups for volume adjustment. (If this not enabled by default, go to Control Center→KDE Components→Service Manager, make sure the "Use" box for "KMilo" is ticked, and if necessary, start it by clicking the "Start" button.
Not tested; check back later.
To enable the three application buttons, add the following lines to /etc/init.d/boot.local:
setkeycodes 74 93 setkeycodes 75 94
Then add the following to /etc/X11/Xmodmap:
keycode 131 = F13 keycode 128 = F14 keycode 208 = F15
