Hi there,

Installed the latest AVLinux today, hoping to be ready for our first rehearsal with singer next week   Smile  and wanted to use it first to load soundfonts for the keys, and record rehearsals.

Live DVD seemed to work ok, first boot ok. I then shut down, plugged my RME hammerfall through cardbus (been using it for years on linux, first distro was StudioToGo ! ) and start again : after few seconds it seems that something (perhaps related to graphic drivers?) goes wrong. Symptoms :
 . mouse is very slow , huge delay...hardly usable
 . keyboard is slow too : I have to type slowly otherwise it misses half of what I type
 . graphic display is slow : in linuxsampler ( the only thing I used so far) , closing a panel takes a few seconds
 . don't know if related to the same issue, but after a few minutes I didn't have any sound anymore ( Jack was ok, audio and midi connections in Jack ok, audio and midi in linuxsampler ok too) ...never experienced that...usually jack dies or something crashes but today no sound and no obvious reasons.

System :
AMD 3800+
Nvidia graphic card (not at the studio before next wednesday so can't check reference of the card before, but it is a few years old and never had issues before on other distros , including AVLinux 4.2...)

|I tried to boot from kernel with proprietary drivers but it failed. Rebooted from generic kernel and it worked ok for few seconds, and started playing funny again...

I remember that years ago on the same computer, I had to add a line in the kernel related I think to acpi ...

I am tempted to reinstall 4.2 to get something working for rehearsal on wednesday.

Any advice?

ps : thanks for this distro... installed it in a school a year or  so a go, they couldn't believe they had a full sound studio up and running in no time!

Yikes!  It's not supposed to act like that!

It could be a kernel issue, for a quick way to check that, try installing this AVLinux Liquorix kernel build, this should be similar to the kernel in AVLinux 4.2:
http://www.bandshed.net/kernels/2.6.36-3.dmz.2-default.zip

If using that kernel doesn't change anything, it might be helpful to check with top (in a terminal) or the qps system monitor to see if there is a process that is hogging your cpu.  Hopefully we can figure out what is going on here...

Thanks for the tip Trulan.

I had an opportunity to double check this morning and it is definitely as soon as I start Jack that things start to go wrong.
I installed the new kernel, but can't even login when booting from it as I have a display message : something like 'out of range 92khz, ...'

So a bit stuck right now Roll-Eyes

BTW, qps is the most power hungry process with or without jack, shewing 3 to 6% of cpu at any time.
