So, running the aforementioned RT kernel, managed to patch the latest nvidia driver following these general instructions: http://ubuntuforums.org/showpost.php?p=9233282&postcount=5 I'm already happy because it's quite some time that i haven't had the RT kernel!
As i don't use GEM i cannot tell about it, but Pd got faster. Almost as fast as the 32-bit Pd was (on 64-bit Ubuntu - Hardy that time). It means i can almost use my MIDI sequencer patch without the GUI dropping out. Promising! Now i can dig into the patch for optimisation possibilities, and at the same time, keep on bugging the community for speeding up the GUI :o)
Do you guys think i shall try it with a current 32-bit Pd to see if the 64-bit version is really slower...?
(on a side note to RT kernel experiences: the CPU got hotter indeed, looks like i'll have to tweak the cooling fans again...)

hello, 195.36.24 is the nvidia driver version i'm using. mainly because it's the version shiped with ubuntu 10.04. i don't know what 260 would offer better, but i think it's not impressive. most of nvidia upgrade is adding support for new card. anyway, if you don't use graphics for any important stuff, then you probably don't care.
i'll be interested to know your impression if you try this kernel for pd/Gem.

i'm using Ubuntu Lucid with standard kernel (64-bit), and performance in Pd hasn't really impressed me lately... and WHOA i've just found a PPA with RT kernel (https://launchpad.net/~abogani/+archive/ppa/https://launchpad.net/%7Eabogani/+archive/ppa/), which i'm very interested in - it's just that it comes with older Nvidia drivers 195.36.24 while the latest drivers from Nvidia are 260.19.21. Now does anyone know if i'll loose anything important with this older (but appropriately patched for RT) graphics driver? (btw i don't use graphics for anything important...)

hello,
you say that you need a RT kernel : did you benchmarck the difference between a RT kernel and a standard kernel?
anyway, i'm using ubuntu 10.04 with no optimisation. compiling pd/Gem is very fast and easy, so i don't wait the official package...

Hi all! I have realized lately that Fedora/PlanetCCRMA may not be the best linux rt distro out there in terms of updates for Pd. So I wanted to conduct a survey among pd-list members to know who is using what. It seems like Ubuntu Studio is the distro that's most frequently updated. Too bed because the last time i tried to install it on my laptop it didn't work... Any advice would be appreciated. I need a rt kernel, of course... Pierre
