X-Swat has not updated their ati packages in a long time which means that Natty users and Maverick users with 2.6.38 (64-bit) cannot run with fglrx video drivers.
In order to get the latest 2.6.38 kernel and fglrx playing nicely together you will need to build these packages yourself.
Custom build procedure:
Cisco’s new line of equipment now use a mini-USB cable for console configuration. There is no longer a need for a USB to serial adapter or a roll-over cable.
Connecting the USB cable on Linux should give you a new ACM device that looks something like this: “/dev/ttyACM0″.
To verify, you can also look through your dmesg or /var/log/messages :

If you want the latest (read bleeding edge) kernel that the Ubuntu developers are working, then have a look here:
Be sure to download the 3 files matching your architecture and install.
I am currently using 2.6.37-rc3-natty which will be the kernel that Natty Narwhal (11.04) will be based on. It just works, everything is detected and there is a noticeable increase in responsiveness.
The Feather or the Anvil?
First a bit of background: I was tasked with created a high level tester for my company’s system. The idea is create 1 or more monkeys to pound away at the company’s product for a very long time. A concurrent parallel programming project with the requirement that it needed to be compatible with 2.6.2 version of Python.
With threading, you get real posix threads (pthread) which works pretty well. They implicitly share state with the parent thread and do not use IPC or messaging. They have low latency and low overall resource footprint.
However there are drawbacks that made further development using threads a real problem. that is the use of signals. Such as threads not handling signals, working with the global interpreter lock (GIL, only one thread allowed to run at a time), and more. Read moreWritten by Bret Curtis
With the release of Ubuntu (Meerkat) 10.10 just 10 days away, the ubuntu x-swat people have been busy getting fglrx ready for release. The fglrx now compiles against latest Meerkat kernel and finally resolves the unknown symbol issue.
In the laptop is a ATI Mobility Radeon HD 3670 and with the latest fglrx driver usability is awful. There is horrible tearing when using “Appearance -> Visual Effects -> Normal”, which had to be set back to “None” just to be usable. Even on “None”, scrolling down in documents, chrome, firefox and Skype all give blurred or stuttered graphics.
These are for me “do not use” releases.
