Overview

There are no particular problems installing Ubuntu Dapper (6.06.1) or Edgy Knot2 (6.10 alpha) on a R60e.

If the Windows and Service Partitions are to be retained then the Gnome Partition Editor can be used from the live cd to shrink the Windows partition (sda1). The IBM recovery partition is placed at the end of the HD disk. Note that the Recovery partion is not located on a cylinder boundary and is placed between 'unused' disk areas, 3MB in front and 7MB behind. These appear to contain the diagnostics programs and should not be moved or resized if the diagnostics and R&R programs are required.

To repartion: boot to Windows and immediately create a Rescue and Recover disk set. If you have a USB HD you can also create a Recue and Recovery copy on that. boot with Ubuntu live CD, use Gnome Partition editor to shrink the IBM_PRELOAD (sda1) partition. reboot to Windows and let it run chkdsk boot Ubuntu Live CD and install

Xorg.config for two screens

Intel 945GM The config options are described in the driver man page [$ man i810]. The following sections are for a configuration with the laptop screen as the primary display and an second display on the D-SUB15 analog VGA port. The second display is expected to be a flat panel or a data projector ('beamer').

   Section "Device"
   	Identifier	"Intel 945GM Internal LCD"
   	Driver		"i810"
   	BusID		"PCI:0:2:0"
   	Screen 0
   	Option 	"MonitorLayout" 	"CRT,LFP"
   EndSection

   # 	Option 	"FlipPrimary" 	"no"
   # 	Option  "DisplayInfo" 	"yes"
   #	Option 	"Rotate" 	"CCW"	
   EndSection

Resolution and timing

X and the graphics adaptor will detect an external screen if present and attempt to auto negotiate an appropriate resolution and refresh rate. It is unclear from the Xorg/XFree documentation how the useable video modes are selected/rejected but it appears that if a monitor is connected to the VGA connector the highest available VESA resolution will not be selected unless it has a refresh rate of 75Hz or more. As the optimum refresh rate for a flat panel display is usualy 60Hz, and often the highest (native) resolution only available at this rate, it may be necessary to set a mode line for best performance.

In the case of a data projector, these appear designed to accept inputs for resolutions and refresh rates far in excess of their native SVGA or XGA capabilities and automaticaly convert down, which may entail a loss of image quality. Thus, for these also, forcing a reasonable resolution and refresh rate is desirable.

The possible modes for a connected monitor can be discovered by looking at the X log file [sudo nano -w /etc/X11/xorg.conf] or by running xvidtune.

   Section "Modes"
   	Identifier 	"V75"
   	ModeLine "VGA 75"   31.50  640  656  720  840  480  481  484  500

The monitor Most recent monitors will supply X with data on available built in modes, and this will overide the HorizSync and VertRefresh values in the config file. However some projectors do not supply this information and fail to display unless the HorizSync and VertRefresh are configured.

   Section "Monitor"
   	Identifier	"LCD on D-SUB15"
   	Option		"DPMS"
   	HorizSync	31-75
   	VertRefresh 	60-75
    	UseModes 	"V60"
   	UseModes	"V75"
   EndSection

Note that with this layout the mouse will move off the right hand edge of the laptop screen and make an entrance on the left of the external monitor. If you can't find the mouse it may be on the other screen, try moving it top left.

Sound

There is an option in the BIOS setup to disable the modem which seems a good idea if the modem is not needed. Do not do this, if the modem is disabled then sound will not work with Ubuntu (6.06 and Edgy knot2). (Sound does however work in WinXP with the modem disabled)

Mouse and TrackPoint

see How_to_configure_the_TrackPoint Note however that to modify sensitivity and scroll rate on R60e with Ubuntu 6.06 the commands are:

    # echo -n 96 > /sys/devices/platform/i8042/serio0/speed
    # echo -n 200 > /sys/devices/platform/i8042/serio0/sensitivity

This needs to be typed in a root window; using sudo gives a permission denied.
