Dear Linux fellows,
Could I ask you something about ASUS EEE and Supercollider3?
i have tried to install supercollider on my 701 xandros advanced
but something doesn't work, this is the screen of the console:
eeepc-user:/root> jackstart: cannot get realtime capabilities, current
capabilities are:
=ep cap_setpcap-ep
probably running under a kernel with capabilities disabled,
a suitable kernel would have printed something like "=eip"
back from read, ret = 1 errno == Success
jackstart: could not give capabilities: Operation not permitted

JACK compiled with System V SHM support.
`default' server already active
what's the meaning of this?
Thanks a lot!

You need a 'realtime' kernel. On debian based systems, these are kernel
packages named something like 'linux-image-2.6.18-rt'. You can also
compile your own but getting a prebuilt one is much easier.

for more info on what realtime scheduling is and how to set it up on a
standard linux distro (may be harder in EEE-Xandros)
