Installing Ubuntu 11.04 (Natty Narwhal) on a ThinkPad X220
I installed Ubuntu 11.04 (Natty Narwhal) on a ThinkPad X220, model 42902GW.
Netboot
As a source of network installation files I made use of another GNU/Linux computer on my home LAN which is connected to the Internet through a familiar ADSL-modem/gateway/router/caching nameserver/DHCP server (call it "the gateway") at address 172.19.3.1. The gateway's DHCP server issues leases in the range 172.19.3.2 to 172.19.3.100.
First I set up the "source" machine, in my case one which already also had Ubuntu 11.04 installed. It has address 172.19.3.7 (assigned to it by the gateway's DHCP server). For the X220 to boot from it the machine needs to run a DHCP server and a TFTP server. The DHCP server serves only this special purpose since, as I mentioned, the gateway is the network's main DHCP server. The source's DHCP server must be so configured that it doesn't conflict with the existing DHCP server.
Install the isc-dhcp-server package and edit /etc/dhcp/dhcpd.conf using the following as a model. I am not sure that every line is needed, but this worked for me.
ddns-update-style none;
option domain-name-servers 172.19.3.1; # This is the address of my gateway
option routers 172.19.3.1; # This is the address of my gateway
option subnet-mask 255.255.0.0; # This is the netmask of my home network
default-lease-time 600;
max-lease-time 7200;
allow booting;
allow bootp;
subnet 172.19.3.0 netmask 255.255.255.0 {
range 172.19.3.220 172.19.3.229; # This is a range separate from the one used by the gateway and includes the address below
}
group {
next-server 172.19.3.7; # This is the address of the "source"
host trawsfynydd { # 'trawsfynydd' is the name I chose for my X220
hardware ethernet f0:de:f1:6b:22:bf; # This is the Ethernet address of the X220
fixed-address 172.19.3.220; # This is an address in the range as defined above
filename "/pxelinux.0";
}
}
Now install the tftpd-hpa package, download the network installation tarball and untar it into the location whence tftpd serves files.
$ cd /tmp $ wget http://archive.ubuntu.com/ubuntu/dists/natty/main/installer-amd64/current/images/netboot/netboot.tar.gz $ cd /var/lib/tftpboot $ sudo tar zxf /tmp/netboot.tar.gz
Second set up the X220 for PXE (Pre-boot eXecution Environment).
- Switch on the X220 and press F1. ThinkPad Setup starts.
- Set Config | Network | Ethernet LAN Option ROM to "Enabled".
- Select Startup | Boot; select "PCI LAN IBA GE Slot..." and use the [+] key to move it to the top of the boot priority order
- Press F10 to save and exit.
Voilà, the X220 boots the Ubuntu installer.
Installation
I won't describe the Ubuntu installer. I'll just mention some little problems I had.
First, when it came time to resize the existing (ntfs) partition the partitioner asked what size I would like for "this partition". Did it mean the to-be-resized ntfs partition or the new ext4 partition?
Turns out it meant: the to-be-resized ntfs partition, so the suggested "max" selection was the opposite of what I wanted.
Second, when I selected (only) the "Ubuntu desktop" task the installation reported failure without explaining what had gone wrong.
I de-selected all tasks and the installation succeeded.
Third, after reboot the screen came up black.
I pressed CTRL-ALT-F1 to get the system console so I could log in.
After logging in I ran tasksel and installed "Ubuntu desktop" and this time no failure was reported.

Configuration
- Having installed bare Ubuntu I had to run tasksel and select at least "Ubuntu Desktop".
- In order to allow NetworkManager to manage eth0 I had to comment out the "eth0" stanza in /etc/network/interfaces
- I used System Settings | Ubuntu Software Center to install ccsm ("Advanced Desktop Effects Settings") so I could enable Wobbly Windows and so I can initiate window resize with Super+Button3 (i.e., Windows-key+Right-click) which is easier than grabbing a window border or trying to press Alt and the scroll wheel while dragging.
- Add PPAs to apt sources list for additional indicators
Fixes
Fix for no-beep bug
- To fix the known no-system-beep problem create .xprofile containing
pactl upload-sample /usr/share/sounds/gnome/default/alerts/glass.ogg bell.ogg
and add
xset b 100
to .bashrc so that the system bell can be heard.
Fix for "[drm:i915_hangcheck_ring_idle] *ERROR* Hangcheck timer elapsed... blt ring idle..." problem
- To fix this known problem do
echo 1 > /sys/module/i915/parameters/semaphores
and to fix it permanently make the following change to
/etc/default/grub
- GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" + GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.semaphores=1"
Findings
Compared with this Gentoo user's experience
- (improvements)
- I didn't have to do anything special to have the thinkpad-acpi module loaded or use special keys
- Both microphones are seen
- I have no difficulties with the fans
- I have no difficulties with SD cards
- The "Hangcheck timer elapsed" problem has a workaround as described above
- (disimprovements)
- Suspend doesn't work: it causes a general protection fault
Things to look into
Make a key table
... as I have done in the past.

Fix suspend
"Suspend-to-RAM and brightness control of the display work with kernel >= 3.0-rc6" according to this fellow.
Does the mic hardware mute button work?
No.
