Fix Google Earth 5.0 user interface font on Linux

I installed Google Earth 5.0 and the ugly UI font from the beta is still here.
Based on the comments from Google Earth Help page from here I’ve created the following script wich will fix the user interface font issue.

HOWTO Force fsck on the Next Reboot

fsck is used to check and optionally repair one or more Linux file systems.
By creating /forcefsck file you will force the Linux system (or rc scripts) to perform a full file system check.
Create a file called forcefsck:

View Config Files Without Comments

Use this grep invocation to trim comments out of config files. Comments are great but can get in your way if you just want to see the currently running configuration. I’ve found files hundreds of lines long which had fewer than ten active configuration lines.
It’s really hard to get an overview of what’s going on when you have to wade through hundreds of lines of comments.

The regex ^[^#] matches the first character of any line, as long as that character that is not a #. Because blank lines don’t have a first character they’re not matched either, resulting in a nice compact output of just the active configuration lines.

Thinkpad HDAPS in Ubuntu 9.04 Jaunty

One of the cool features in a Thinkpad is IBM Active Protection System.
The system consist of two parts. The driver that enables reading the acceleration data and some sort of userspace software that does the actual parking of the harddrive heads, usually hdapsd.
The hdaps driver is part of the kernel but the driver maintainers actually recommend using the tp-smapi driver instead. So that’s what we’ll do.
Make sure you have the necessary tools installed:

The tp-smapi is in the package repository (universe):

This will fetch and install the tp-smapi-source package, unpack the source and then compile and install the kernel module.

Try loading it:

The kernel log should show something like this:

For some reason some configuration for udev is missing. Fix this by running:

Now for the userspace stuff. First let us test if APS is actually working.

This will install hdaps-pivot or hdaps-gl which you can use to verify that the sensors are working.
You can also test this by running this in your terminal (stop it with pressing CTRL + C):

Next we need to update the hdapsd. The one provided in Jaunty is old. There is a PPA with newer versions.

Add the PPA key:

Update the package list and install the package:

Install gnome-hdaps-applet (optional).
There is a PPA for this. You can add it like this:

Add the key:

Update the package list again and install the packages:

Enjoy!

Random crash of the X server in Jaunty

I experienced a lot of random X server crashes using the proprietary driver for the NVIDIA graphic card on my Thinkpad T61 running Ubuntu 9.04 x86 with Compiz activated.
I managed to fix the problem by installing the lastest NVIDIA driver. I wrote a little script to automate the process and save time. I recommend you to run this in command line mode. Here it is:
