A wifi-connected laptop as a home server May 29, 2008

As probably many people nowadays, I only have laptops at home. Actually one for me and one for my girlfriend (luckily babies don’t need laptops yet 
). As we made the move to laptops a long time ago, you end with older – perfectly fine – laptops. Similarly, I stopped making holes in the walls a long time ago and went wireless.
Laptop and wifi do not sound like a winning server combination, but for me they are. Happily, nowadays wifi is as easy in Linux as in Windows or MacOsX. But do you really want you laptop to use a graphical semi-interactive process to get it’s – often random – IP address? What if the machine will run without an X server?
wpasupplicant and the old manual network configuration come to the rescue. I use this configuration for my graphical over-sized living room divx/mpeg/flac/ogg/mp3-player laptop connected to my tv and stereo and non graphical print server (an old trusty amd 350mhz cpu with 160 mb ram and 4 gb disk) in the home office (far from the living room where we often work).

For the googlers out there: Ubuntu 8.04 – and for that matter the previous versions as well – works completely out of the box on this laptop.

This is just a wrapper post for all the people googling for installing GNU/Linux on a nc6320 laptop:
Ubuntu 8.04 runs just fine on this laptop (bluetooth, card reader, 3D compiz effects, etc, etc). The install is very easy and straight forward. There are two things you need to fix: enabling the mic and pump up the wifi speed. The only thing I haven’t tried is the fingerprint reader (I find it silly).
Broadcom wifi (BCM4312) speedup to 54mbit/s on Ubuntu 8.04 on a HP nc6320 laptop [Now FIXED on Ubuntu] May 21, 2008

EDIT May 27th 2008: FIXED how to make the changes permanent.
EDIT June 4th 2008: Don’t forget to install as well linux-ubuntu-modules (in this case linux-ubuntu-modules-2.6.22-14-generic) when upgrading your kernel.
EDIT Oct 16th 2008: The restricted driver included in Ubuntu has been FIXED and the card works out of the box when enabling it through System-Administration-Hardware Drivers. Thanks, Ubuntu!
It’s probably a regression: on this laptop the broadcom wifi worked fine on the previous Ubuntu releases (although limited to 24mbit/s) and now I see the speed is stuck to an unacceptable 1mbit/s. I guess that’s the price you pay for hardware from companies that are not open source friendly. (more…)
Sun Workstation w2100z and Ubuntu 8.04: no keyboard or mouse May 5, 2008

When upgrading to Ubuntu 8.04 (or when booting with the live disk), my workstation (Sun w2100z) lost the keyboard and mouse (both are usb). Both were present and enabled at boottime (I chose the language and keyboard layout at boot time of the live cd). Luckely, the problem is solved.

There is a bug on the sound setting for my main machine, a HP nc6320 laptop. Everything seems to work fine on GNU/Linux except the microphone.
This is the chipset of my soundcard (in case you have the same problem on an other type of machine):
claudio@brisbane:~$ lspci |grep -i audio

Lotus Notes 8 on Ubuntu 64-bit November 9, 2007

Ok, let’s be clear. Lotus Notes sucks. However, on my workplace all mail and calendar (meetings!) are administered through Lotus Notes on Windows. I run GNU/Linux (Ubuntu). All the hassle show how close source software sucks if you have configuration slightly different that expected by the seller. I am not running Windows or 32-bit RedHat. This post is a work in progress and will be adapted.
This is what I did to get the client running on Ubuntu 7.10 amd64: (more…)
