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 more
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.
After a brief time with Karmic (10.04), the laptop was upgraded to the beta of Maverick. Everything works out of the box with no additional tricks necessary in getting the Dell Studio XPS 1640 fully functional.
The only drawback I found in upgrading from Karmic was the loss of fglrx as a xorg-server driver. Maverick is shipping with the 1.9 version of xorg-server which is ABI incompatible with what fglrx is compiled against.
The exact error is:
undefined symbol: savedScreenInfo
which causes X not to start.
The very first thing I did when the company I work for gave me a laptop, a Dell Studio XPS 1640, was to install Ubuntu Karmic on it. No need for windows on this thing, I plan on working, not playing.
Dell is very good about their laptops. Whenever I had a question, everything I ever needed to know about their hardware I could easily look up on the online. The 1640 is no exception with their manual.
