Install ubuntu 10.04 on thinkpad L420

4 Comments Posted by on September 17, 2011

My L420 has the serial number 78544KM. There are other serial numbers available and seems like the devices are a bit different, i.e. the wireless device.

Run following command in your shell should give you what your wireless device is

lspci -nn | grep -i network

Mine is this:
03:00.0 Network controller [0280]: Intel Corporation Device [8086:0085] (rev 34)

I initially install ubuntu 10.04 LTS and the kernel version is 2.6.32-33-generic. According to this post upgrade kernel version to 2.6.36-xx will fix it. But at that time I went to the other option, installing a compact wireless driver. It worked.

There is another problem with ubuntu 10.04. The screen resolution is max at 1024*768 which isn’t the full capacity. I posted a thread in ubuntu forum and get the answer to upgrade to newer kernel version.
Here is the command to do it.

sudo add-apt-repository ppa:glasen/intel-driver
sudo add-apt-repository ppa:kernel-ppa/ppa
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install linux-image-generic-lts-backport-natty linux-headers-generic-lts-backport-natty

From the first post link, it seems like for ubuntu 10.10, you can upgrade to
linux-headers-2.6.36-1 directly without having to use a backport version from a ppa. I may give it a try if I need to reinstall my os again in the future… while unity still sucks to use…

    Hi there. Do you use 32 or 64 bit on your machine. I have same as yours and cannot install 64 bit without noapic boot option.

    Thanks
    Steve
