[linux-audio-user] Laptops for audio

Hi, I'm using my laptop to make some music. At home I planning to buy a computer with enough power to host a lot of music software. But when I'm away from home I'd like to use my laptop. The thing is that according to the specification on my laptop it would be enough power to run lots of demanding software. But there is, for example, Rosegarden and I have problem with xruns when I try to run that. I have an ACER Ferrari 3000 (a damned hot bastard that makes me wonder if the ACER community doesn't have a fertility problem if they really have this thing in their lap ;-) that has an Athlon-XP-M 1800+. I had a lousy HD in it that i changed but that only boosted the memory-to-HD performance. I seem to have other problems. The graphic is one thing. I have done all the things for real time performance and other stuff to get down the latency but still there is performance problem. It seems to be connected to jack but I'm not really sure. It would be interesting to here about other people who have set up laptops for music production. If there's already a site or compiled list of systems and how they perform I would be delighted to be pointed to it. But if it's not it would be nice if we could start a thread with how laptops are performing as music stations. Here's my system Model: ACER Ferrari 3000 Soundcard: VT8233/A/8235/8237 (yeah I know. crap) OS: Linux/Gentoo Kernel: 2.6.10-gentoo-r4 Audio: ALSA Audio-server: Jack-0.99.0-r1 Measurements Latency: Haven't had time to test this yet.
