I'm on Xubuntu 13.10 64 bit. The output of lspci, lspci | less, and lspci -v is here.

Ubuntu tells me that there are 3 video cards drivers compatible with my PC. By default Xubuntu picked the first one.

enter image description here

But which one of these 3 is the best? Which one should I use?

  • yesterday my xubuntu went to tty suddenly, everything worked after I restarted. so I'm afraid that Im using the wrong driver... maybe? – Lynob Feb 7 '14 at 19:21
  • lspci | less only makes a difference when viewing it in tty :) - Were you using the Xorg driver when it went to the tty? – Wilf Feb 7 '14 at 20:15
  • @wilf yes I were using the one showed in the image, I haven't change yet, I am asking this question to see if i should change it – Lynob Feb 7 '14 at 20:26

    Have you tried using the other drivers? There is a page here that may be of help - I think fglrx does better 3D stuff, whilst radeon does better 2D stuff - I find the radeon one works fine for Games etc on the 6360M/7370M card on my laptop. – Wilf Feb 7 '14 at 20:30

    Use the last one. It's been tested well, and should work. Good luck. – mikewhatever Feb 7 '14 at 20:34

The open source drivers are fully supported by Ubuntu and provide support for older hardware which the proprietary drivers have abandoned. In my experience they are also more stable and less prone to random bugs and glitches (Unity randomly failing to start etc), although other people's experiences may vary.

The proprietary fglrx drivers on the other hand tend to support the very latest hardware before the open-source drivers have time to catch up, and provide much better 3D performance which is critical for games (although the performance is often still much worse than on Windows). Until recently they also implemented much better power management although this may no longer be the case following the recent radeon DPM changes.

If the open-source driver works fine for you, stick with it — there is no need to switch to fglrx just for the sake of it. If you want to play modern 3D games on Ubuntu however, or your graphics performance is very poor and you have a latest-generation GPU, you are probably better off with fglrx.
