Installing Ubuntu on a ThinkPad R60e
There are no particular problems installing Ubuntu on a R60e.
Most of the information here is based on a clean install of 6.06.1 with upgrade to 7.04 via 6.10. Significant changes that apply to Edgy (6.10) and Feisty (7.04) are noted here.
Ubuntu 6.10 "Edgy Eft"
If the wireless kill switch is active during boot, that is wireless and bluetooth are switched off, there is a high probability that a "soft lockup on CPU0" will occur during boot. Boot appears to be ok provided the wireless is on during boot. See Bug 63418.
Ubuntu 7.04 "Feisty Fawn" 7.04 beta there is a problem with the Fn+home Fn+End screen brightness controls Bug 87028.
The workaround is to disable video.o
echo blacklist video | sudo tee -a /etc/modprobe.d/local
Unfortunately this only fixes the blanking screen, using the Fn+Home and Fn+End provides values of bright and dim but no intermediate values.
The problem with the wireless kill switch seems to have been fixed in kernel 2.6.20.
Partition and Boot
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 and contains a cut down version of WinNT. 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. The first disc of the set must be a CD (though if you put a DVD in it will be formatted and writen as a CD disc); this is a bootable disc. The second stage of the disc writing process will write to either one DVD or 5 CDs. Restoring from these disks will restore to factory state, which means the entire hard drive is reformatted. After the disc set is created it is not possible to create a second set. (Although if you update the R+R program you can create a new backup CD/DVD.)
However, if you have a USB HD you can also create a Rescue and Recovery copy on that. I have not tried (sucessfully) but I it should be possible to boot and restore from a USB HD recovery set and preserve any new partitions provided that: the windows partition is not too small, and the Recovery partition is preserved.
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
The live CD will install GRUB to the MBR. For most users with a simple dual boot (Linux + Win) this will be fine; the installer will identify both IBM_PRELOAD and the service partition and provide boot options for both. (If you have need of a more complex boot arrangement, such as multiple linux versions then install using the Ubuntu alternate install CD.) Edit /boot/grub/menu.lst to add the hide and unhide lines (this will prevent Windows showing the Service Partition).
# This entry automatically added by the Debian installer for a non-linux OS # on /dev/sda1 title Microsoft Windows XP Professional hide (hd0,1) root (hd0,0) savedefault makeactive chainloader +1
# This entry automatically added by the Debian installer for a non-linux OS # on /dev/sda2 title IBM/Lenovo Maintenance unhide (hd0,1) root (hd0,1) savedefault makeactive chainloader +1
The default kernel at install will be linux-image-386. Install Base System linux-image-686 for full support of the core-duo processor including SMP. (The older linux-image-SMP kernel is not required and may not perform as well as it is intended for servers and does not have the pre-emption patches.) You will also need Base System (restricted) linux-restricted-modules-686 as the Intel wireless card driver loads binary firmware.
For Edgy-Eft (6.10) the default kernel linux-image-generic will fully support SMP so installing a kernel should not be necessary.
Xorg.config for two screens
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').
There are some tradeoffs with Xorg.conf, the version below is intended to give the best available resolution with a variety of external screens without the need to change xorg.conf. See the notes at the end of this section for some other optimisations.

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

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.

Note 1 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.
Note 2 The gnome desktop can be configured for each monitor. But it is not possible to transfer a window from on display to the other. Trying to start Firefox on one desktop when it is opened on another monitor will give a message: "Firefox is already running, but is not responding. To open a new window you must first close the existing Firefox process, or restart your system".
Xinerama To be able to drag windows from one screen to another and fix the problem in Note 2, enable Xinerama extension. However with Xinerama enabled the resolution of the external display will default to XGA, the same as the laptop screen. The Gnome menu System:Preferences:Screen Resolution will respond with: "The X Server does not support the XRandR extension. Runtime resolution changes to the display size are not available", nor will Gnome provide a separate desktop task bar etc. note [here] This problem can be overcome by defining the preferred resolution - and only that resolution - for the screen and server layout. eg.

This may be a better config if you always use the same external screen, but less satisfactory if you need to connect to a variety of external screens. The RandR extension is currently under development so some of these problems may be resolved with newer versions of RandR see: Xorg Developer Conference 2007 and X RandR v1.2.
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.
You need to install linux-restricted-modules-generic, which contains the kernel module ath_pci. ath_pci is loaded automatically at system startup.
Feisty (7.04) includes network-manager, although useful for roaming it dosn't work well for networks which do not broadcast ESSID.
There seems to be a bug in edgy in relation to cpufreq governors. See Bug 70602 for details and a workaround.
Had to add following script to let the laptop go into supsend after the lid was closed:
#!/bin/sh #/etc/acpi/local/lid.sh.post grep -q closed /proc/acpi/button/lid/*/state if [ $? = 0 ] ; then /etc/acpi/sleep.sh fi
Both Sleep (fn+4) and Hibernate (fn+12) appear to work.
If not used: see above re sound
If used: install mwave then it should work.
