Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I'm a pretty experienced Linux user. I started 20 years ago with Slackware before GUIs existed and transitioned to Debian before quitting Linux for a while. Last night I got the itch to install Ubuntu again (my previous experience being Ibex I think).

I am installing it on a gaming rig which is probably not optimal for a lot of things Linux needs but with the processor/ram/video card I find it hard to believe I am experiencing such issues.

  1. Interface lag - nothing happens fast. Using Tweetdeck, tweets come in via my timeline and "ghost in" as if they transition in in slow motion (hard to explain but video ghosting is the best explanation I can provide for it)

  2. typing a URL into FireFox is abysmally slow. Before I can put in the first four characters, the first two have just typed.

Things I've tried:

  1. write-caching on hdd
  2. changing to all three of the available ATI/AMD drivers available in Software Center.
  3. I've also tried the newest ATI/AMD drivers available on their site.
  4. Made some tweaks to Compiz in OpenGL

(I've also tried Fedora with the same results so I know it's driver/software related and not something Ubuntu has specifically done)
