The least hassle-free option would probably be to enable them all. Then, you can use the "elevator=" kernel option to set the default at bootup; and you can view or change the scheduler in use at runtime by reading or writing to /sys/block/<device>/queue/scheduler, respectively. (You'll mostly have to become root to do this. Run "su -" in a terminal to become root temporarily.) If you want more information about what each one does in detail, you can install the kernel-doc package and take a look at the text files in the /usr/share/doc/kernel-doc-version/Documentation/block/ directory. Hope that helps. -- Peter Gordon (codergeek42) GnuPG Public Key ID: 0xFFC19479 / Fingerprint: DD68 A414 56BD 6368 D957 9666 4268 CB7A FFC1 9479
