Ubuntu 10.04 Alpha 2 vs. Early Fedora 13 Benchmarks 157
Given that early benchmarks of the Lucid Lynx were less than encouraging, Phoronix decided to take the latest alpha out for a spin and has set it side-by-side with an early look at Fedora 13. "Overall, there are both positive and negative performance changes for Ubuntu 10.04 LTS Alpha 2 in relation to Ubuntu 9.10. Most of the negative regressions are attributed to the EXT4 file-system losing some of its performance charm. With using a pre-alpha snapshot of Fedora 13 and the benchmark results just being provided for reference purposes, we will hold off on looking into greater detail at this next Red Hat Linux update until it matures."

It's all worked perfectly for me on the three computers I've tried it on, PulseAudio included. The ability to move audio from one output device to another is awesome - Windows certainly can't do it!

Windows 7 or Vista instructions: Right-click on the little speaker icon in the bottom right. Click "Playback devices". Right-click on the device you want to use instead of you current device. Click "Set as Default Device". The audio output will instantly switch to that device.

Even though PA has had it's share of compatibility problems, it is working much better now. Things (sound devices) that never worked before actually work now and switching between them is possible -- on the fly --, when they weren't working at all before. It's so great to be able to use high quality audio for music/games, and a USB headset for phone calls.
Things are looking up on the PA front.

Consider when a typical application exits. It does something like:
* Write new config file to a temporary file
* Rename the temporary file over the top of the old config file
This way if the computer crashes, applications expect the config file to always be valid. i.e. they expect the data to have been written to disk, completely, before the rename happens.
This worked in ext3 and other filesystems, but originally not in ext4. The result was that the config file could end up being empty.

It isn't gone.
In Ubuntu Karmic (9.10) or probably any GNOME you can restore [econowics.com] Ctrl-Alt-Backspace [digitivity.org].
Just go to Keyboard preferences, keyboard layout options, and enable the ctrl alt backspace key combo.
