While trying to use Chromium on a Ubuntu 64-bit machine, I discovered I wasn’t able to browse to any web page. I always got the following error message:

libvirt and virt-manager are a blessing. They bring powerful, free, open source management to Xen- and KVM-based virtualization environments.
I’ve been using both for quite a while. Also, I’ve always prefered bridged networking support for my virtual machines over NAT. While NAT is non-disruptive and allows for isolation, I typically like to easily access services provided [...]

Recently, I upgraded to Ubuntu 8.10 Intrepid Ibex and found that my Thinkpad’s TrackPoint scrolling stopped working. While searching on the Internet, I found a post called Scrolling with the Thinkpad’s TrackPoint in Ubuntu 8.10 Intrepid by Phil Sung that explains in a clear and concise way how to enabling scrolling in Ubuntu 8.10 using [...]

This post is not about doing a PXE-based network installation of Ubuntu. There are already many posts describing how to do this. This post is about setting up an Ubuntu workstation in diskless mode, such as the workstation boots via PXE and the root filesystem is mounted over NFS.

DISCLAIMER: The contents of this post are mostly based on Manual Installation How-To. Thanks to Brent Davidson and Fabian Franz for writing such a nice HowTo and the beautiful open and free implementation of FreeNX, respectively.
I decided to use FreeNX instead of NoMachine’s own implementation due to the instability of the latter. Most of the [...]

¿A que no parece un sistema GNU/Linux?

Install crypsetup and dmsetup:
# apt-get install crypsetup dmsetup
Install pam_mount:
# apt-get install libpam-mount
Configure PAM to use pam_mount for authentication and session management. PAM authentication captures the user login password, while PAM session set ups the dmcrypt device and mounts it during log on, and unmounts the dmcrypt device during log off.
# echo “@include common-pammount” >> /etc/pam.d/common-auth

I think that Ubuntu Edgy Knot 2 is the first Linux distribution that enables the Composite extension by default for X.org. While this is really exciting, unfortunately it seems to negatively affect DRI and 3D acceleration when using ATI’s closed-source drivers, fglrx.
I don’t know exactly the reasons of this, but enabling Composite extensions disables ATI’s [...]

Install pam_mount:
# apt-get install libpam-mount
Configure Ubuntu to load the loop and cryptoloop kernel modules during boot or else pam_mount won’t be able to mount the cryptoloop devices:
# cat >> /etc/modules

Configure PAM to use pam_mount for authentication and session management. PAM authentication captures the user login password, while PAM session set ups the cryptoloop device and [...]
