Just tried to root my GSM Galaxy Nexus manually several days ago. I followed the instruments on the XDA forum here and here. File used are placed in my skydrive.
Ubuntu Lucid(10.04) originally ships with 2.6.32 kernel. But on my T420 thinkpad, the wireless card is not recognized and graphics card is not functional well. Then I switched to 2.6.38 backport kernel, and installed bumblebee package to utilize the Nvidia Optimus Technology. Now the 3.0.0-16 backport kernel is out, it contains the fix for “rework ASPM disable code”, and it should do a better job in power saving even using the discrete Nvidia card. Moreover, it’s the new LTS kernel, so I decided to update to the 3.0 kernel. Please follow the steps if you are interested:
These commands install official nvidia driver. Currently, it’s the 295.20 version.
2. Enable Nvidia Driver
1
# sudo update-alternatives --config gl_conf
This will let you to choose opengl engines. Select nvidia over mesa. This will also enable nvidia Xorg drivers, blacklist nouveau driver and add nvidia-xconfig into /usr/bin. You may find warnings like:

2
update-alternatives: warning: skip creation of /usr/lib32/vdpau/libvdpau_nvidia.so.1 because associated file /usr/lib32/nvidia-current/vdpau/libvdpau_nvidia.so.1 (of link group gl_conf) doesn't exist.
update-alternatives: warning: skip creation of /usr/lib32/libvdpau_nvidia.so because associated file /usr/lib32/nvidia-current/vdpau/libvdpau_nvidia.so (of link group gl_conf) doesn't exist.
Just ignore them, seems to be safe.
1
# sudo nvidia-xconfig
This will generate new /etc/X11/xorg.conf file for your Nvidia card. If you cannot find the command, the original location is: /usr/lib/nvidia-current/bin/nvidia-xconfig
3. Fix ld Bindings
1
# echo "/usr/lib/nvidia-current/tls" | sudo tee -a /etc/ld.so.conf.d/GL.conf > /dev/null
This just add an ld path into /etc/ld.so.conf.d/GL.conf, otherwise, glx module cannot be loaded correctly. Here’s the /etc/log/Xorg.0.log segments:

(II) LoadModule: "glx"
(II) Loading /usr/lib/xorg/extra-modules/libglx.so
dlopen: libnvidia-tls.so.295.20: cannot open shared object file: No such file or directory
(EE) Failed to load /usr/lib/xorg/extra-modules/libglx.so
(II) UnloadModule: "glx"
(EE) Failed to load module "glx" (loader failed, 7)
Now, update ld runtime bindings and reboot.

# sudo ldconfig
# sudo reboot
4. Verify
1
2
# sudo apt-get install mesa-utils
# glxinfo | grep -i opengl
If your installation is successful, the output looks like:

After installing the driver, hedgewars shows 120fps. While it used to show 4fps. It’s a great improvement. 🙂
Method 1:
It is possible to clobber your keyring passphrase and settings from the Terminal. Open a terminal (Applications > Accessories > Terminal), and run the command:
1
# rm ~/.gnome2/keyrings/login.keyring
On older systems you may need to try:
1
# rm ~/.gnome2/keyrings/default.keyring
Method 2:
The second method bypasses the Terminal and uses the graphical interface strictly. To delete your current keyring, follow the steps below:
Navigate to Applications > Accessories > Passwords and Encryption Keys
Select the far-right tab “Passwords”
Select your keyring
Right-click and attempt “Change Password” or, if that doesn’t work, select “Delete”
I used to have lrcshow-x, but it seems to be hard to install and do not cache lyrics locally. From the osdlyrics download file list, use the 0.4.0 version for Ubuntu 10.04 (Lucid). Newer versions are broken in MPRIS2 protocol handling, see here.
