This post applies to users with a fairly new ATI video card.

Does your computer lock up while the screensaver is running ever since you updated to Ubuntu 5.10? The solution appears to be updating your video drivers. In the Synaptics package manager, search for and install the package xorg-driver-fglrx or from the command line type:

apt-get install xorg-driver-fglrx

For those of you in Computer Science 223 using Ubuntu you'll want to install the libsndfile and portaudio packages.

If your version of Ubuntu doesn't seem to have portaudio, you can either manually install portaudio from the URL above or download the Debian packages from:
Development library
Dependency for the development library.

Everyone who came in and had us help set up Ubuntu Linux, please read this. We didn't realize that the G++ compiler had been separated from the GCC package, so you don't have a C++ compiler installed.

Please use the Synaptic package manager to search for "build-essential" and install that package.

Several people have noticed that Ubuntu does not come with a development environment. Well, fear not! Adding software is simple and there's even several pretty nice IDEs to choose from.

First, follow the steps on this web page: https://wiki.ubuntu.com//AddingRepositoriesHowto

Second, use the package manager to install build-essential, which should pull in gcc, gdb, ddd. Then if you want an IDE, install either anjuta or kdevelop

If you'd like to use Eclipse for 223, there's a howto here: https://wiki.ubuntu.com/EclipseIDE

As always, post comments if you have any questions.

• Kdbg
• KDbg is a graphical user interface to gdb, the GNU debugger. It provides an intuitive interface for setting breakpoints, inspecting variables, and stepping through code.
• ddd
• GNU DDD is a graphical front-end for command-line debuggers such as GDB, DBX, WDB, Ladebug, JDB, XDB, the Perl debugger, or the Python debugger. Besides "usual'' front-end features such as viewing source texts, DDD has become famous through its interactive graphical data display, where data structures are displayed as graphs.
