Ubuntu on LENOVO ThinkPad Edge Dual-Core

Guaka — Sat, 05 Mar 2011 10:31:12 +0000

This is a work in progress

Most stuff works out of the box. The main issue is getting wifi to work without issues.

I've used Ubuntu 10.04 with most stuff working nicely for a while, until I got a hard drive issue (I replaced the hard drive with a 60GB SSD). Now I'm running 10.10. Apart from /etc I didn't make a backup of my setup so I have to figure out things again - and I'll keep track of that on this page.

Wireless: r8192se_pci issues

The wireless driver is the r8192se_pci. Many people experience regular (every 2 to 5 minutes) drop outs of connections, especially WEP connections.

A solution, thanks to a kernel panic through powertop: https://bugs.launchpad.net/ubuntu/lucid/+source/linux/+bug/585938

A possible solution is to use RealTek's driver instead of the one that comes with the kernel. You have to compile it yourself though. On Ubuntu forums and even in the issue tracker you will find tons of information, but it's a bit scattered and messy. I hope this page can be more helpful.

At this point I'm not sure what the right steps are to get from a vanilla Ubuntu install to a working wifi. I'll try to update this in the future, but leave comment or let me know otherwise if you have improvements:

$ sudo apt-get build-essentials linux-source
$ wget https://bugs.launchpad.net/ubuntu/lucid/+source/linux/+bug/585938/+attachment/1443893/+files/rtl8192se_linux_2.6.0017.0705.2010.tar.gz
$ sudo find /lib/modules/ -name "r8192se_*.ko" -exec rm {} \;   # removing existing module
$ sudo mv /lib/firmware/RTL8192SE ~   # back up existing firmware
$ tar zxvf rtl8192se_linux_2.6.0017.0705.2010.tar.gz
$ cd rtl8192se_linux_2.6.0017.0705.2010
$ make
$ sudo make install

With previous versions of RealTek's driver you had to use GCC 4.3 but the one used here didn't complain about GCC 4.4.

$ find /lib/firmware|grep rtl81
/lib/firmware/2.6.35-25-generic-pae/RTL8192SE/rtl8192sfw.bin
/lib/firmware/2.6.35-25-generic-pae/RTL8192SE/rtl8192sfw492.bin
/lib/firmware/2.6.35-25-generic-pae/RTL8192SE/rtl8192sfw74.bin
/lib/firmware/RTL8192SE/rtl8192sfw.bin
/lib/firmware/RTL8192SE/rtl8192sfw492.bin
/lib/firmware/RTL8192SE/rtl8192sfw74.bin

After installing the new module you can unload the old one and reload the new one:

$ sudo rmmod r8192se_pci
$ sudo modprobe r8192se_pci

You know everything is fine if your machine doesn't crash when running powertop:

$ sudo apt-get install powertop
$ sudo powertop

32 bit PAE or 64 bit

My ThinkPad came with 4GB of RAM. Since 64 bit is a bit of an issue with RealTek's wireless driver I'm using the 2.6.35-25-generic-pae kernel.

Audio: fixing the audio out issue

The internal speakers might continue playing sound when you plug in headphones or external speakers to the audio out plug. In this case add the following line to /etc/modprobe.d/alsa-base.conf:

options snd-hda-intel position_fix=1 model=leno

Fan control

The fan can be a bit noisy. There's a solution though... I'll add it when I find it back from my backed up /etc.

People want laptops with Ubuntu!

I know many people who want laptops with Ubuntu. Not many people enjoy tinkering with the internals of their OS (and those people run ArchLinux anyway).

If only...

... RealTek contributed directly the Linux kernel.

... Dell had continued selling laptops with Ubuntu in the EU.

... some other company had picked up on this.

Windows Vafanculo: BSOD in less than 30 minutes

I have to admit it, I am typing this using Windows Vista. I really needed a new laptop. I couldn't wait for amylin to bring me a MacBook, and Apple is just too expensive in Europe. I also considered getting a Dell with Ubuntu, but unfortunately, in Europe they're only selling them in the UK, France and Germany. And then I saw an ad of a Toshiba with 160 GB HD and 2 GB RAM, DVDRW and all that stuff, for 599 euros. So I went there this morning and got it. I had considered trying for a refund of the Windows tax but Paolo told me, you can do it with Acer, but you pay the costs of sending the laptop to Milano and having it sent back, which is more than the money you get back. I started my laptop. Vista is yucky. Lots of stuff going on. And then, after not even 30 minutes of using it, without doing anything weird. I copyied some music from an MP3 player, nicely telling Windows that I want to eject it, and I closed the lid. So it went to sleep mode (and I hate it when laptops do that). 3 minutes or so after it woke up I got the Blue Screen of Death. This is what it told me after starting my laptop again:

Firma problema: Nome evento problema: BlueScreen Versione SO: 6.0.6000.2.0.0.768.3 ID impostazioni locali: 1040 Ulteriori informazioni sul problema: BCCode: d1 BCP1: B13C3158 BCP2: 00000002 BCP3: 00000008 BCP4: B13C3158 OS Version: 6_0_6000 Service Pack: 0_0 Product: 768_1 File che contribuiscono alla descrizione del problema: C:\Windows\Minidump\Mini110807-01.dmp C:\Users\guaka\AppData\Local\Temp\WER-81916-0.sysdata.xml C:\Users\guaka\AppData\Local\Temp\WER71E4.tmp.version.txt Leggere l'informativa sulla privacy: http://go.microsoft.com/fwlink/?linkid=50163&clcid=0x0410

Right now I'm downloading an ISO with Ubuntu Gutsy. I hope next time I need a new laptop they will come with Ubuntu out of the box. UPDATE: I started a page about GNU/Linux on the Toshiba L40-157.
