Hi Shayne,

I'm using "kernel-multimedia-2.6.10-3.mm.22mdk#1-1mdk"  from Thac's. If 
you added Thac's repository into APT and saw this and the other MDK 
kernels, you have the right ones. He didn't change the names but did in 
fact recompile them for PCLOS. 


So as for getting Realtime-LSM working right, that is one of the things 
I noticed too...(First, you as root, need to rmmod capability & rmmod 
commoncap then modprobe realtime /with options) In Qjackctl messages, it 
tells me "Cannot lock down memory for R/T" or whatever it is. There are 
several ways to get this and my usual method in MDK 10.1 was to do 
modprobe realtime gid=29. this after adding a group 29 and adding my 
user to that group. It always worked fine. I have done that on this 
kernel but dont seem to be making jackd happy. That said, I dont see 
any, or at best, very few Xruns either.

This kernel should have Alsa 1.09rc2 built in. Jack is the latest 
version I believe.

"and i hope this can be as good as it
sounds :)"  

There are some rough edges now and probably for awhile. Make sure you apply all the upgrades Texstar is putting out. I'm sure you have noticed that it is responsive, light in footprint and quite "snappy" to boot! :) If it's not quite there yet, I'm convinced it will be before too long. I need to test out the mklivecd scripts and test them for myself. Check the IRC channel too. #pclinuxos (not listed) Thac is on there from time to time as is Texstar. Most of the guys are cool and easy to deal with.

Good luck and keep me posted on your successes / failures / thoughts / etc.
