jackstart: cannot get realtime capabilities, current capabilities are:
=ep cap_setpcap-e
probably running under a kernel with capabilities disabled,
a suitable kernel would have printed something like "=eip"

Thanks. I googled this and got various email answers. I figured it out
by trial'N'error

Unfortunately, Xwindows didn't start up. I had to change the
nvidia6111 driver to the older one -- and then X started up. Why
would this be? I was going to install 6111 again -- the nvidia
installer said it was already installed (thought maybe there was
some interaction between this kernel and nvidia6111.)
Anyone come across this?

<pre wrap="">I take that back about the kernel. I did load it successfully (at
least the logs don't say there are problems) but:
# cat /proc/sys/kernel/lowlatency
replies:
cat: /proc/sys/kernel/lowlatency: No such file or directory
so, jackstart doesn't start. of course.
Note that this is NOT from the experimental repos. Perhaps I should
try these, Fernando? You did mention below that these have had more
success. Still...I do wonder why I don't have lowlatency.

<pre wrap="">See this, specially the part about the realcap startup script, the
instructions are different for the 2.6.x kernels...

It didn't help. I think it's something more fundamental.

Exactly like the one that says planetcore (in your
