From Ubuntu 12.04 I upgraded to 64 bit version. Mostly it was smooth but then I stuck by flash. First Chrome 64bit don't have built in flash plugin, that means Google's flash for Linux is not anything if you are using 64 bit. After I installed adobe flash from repository, I am suffering random memory leaks and HANG on chrome for pages with Flash. It was smooth before with Chrome 32 bit on ubuntu 11.10 32 bit. If Gnash or Lightspark support Youtube and Angry Birds for Facebook smoothly, then I would remove the crapy Adobe Flash.
I'll stick with adobe's player until Flash is obsolete in the next few years.
I'm considering switching to it now. I'll probably do so once I install the about-to-hit beefy miracle in the next week or so.
Projects die if don't get bug reports, feature requests, and otherwise just general feedback/discussion from time to time.
I hope every update is posted on Phoronix, so that the profile remains high.
Adobe's Flash on linux is dead, they won't be updating it anymore. If you want somewhere to go when the official plugin has reached a state of deep-defunct, don't let lightspark, or gnash, or any others just die on the vine.
