|I have a fresh copy of Ubuntu 11.10 installed on my Dell Dimension 2400. everything on the machine is stock except I upgraded memory to 1GB and have a radeon HD 2400 pro graphics card|
it is running really choppy. youtube videos skip a lot, it looks like they play at only 5 fps. even at 360p.
also, dragging windows around on the desktop seems very laggy/choppy (it takes a few moments for the windows position to 'catch up' after moving it). loading programs or doing anything graphical on Ubuntu seems to take longer than it should. scrolling down a webpage with the middle mouse button seems to lag a lot.
I installed the proprietary driver from System Settings > Additional Drivers. it was labeled: 'ATI/AMD proprietary FGLRX graphics driver'
after restarting, it says it is activated and currently in use, though the system seems to not be any different, it might even be slightly worse than before.
I had Windows XP installed very recently on this same machine only a few days ago, and it didn't have problems like this at all. it ran smoothly and could play youtube videos up to 480p without being choppy at all, and programs weren't laggy/choppy. dragging windows across the desktop seemed very smooth.
I am an Ubuntu newbie, so I'm not sure what to do. I am thinking maybe the graphics driver isn't installed/activated correctly?
does Ubuntu 11.10 use up a lot of resources? if so, maybe my RAM is too low to run this OS smoothly.
at the login screen, I chose to use "Ubuntu 2d" instead of the default, but the problem persists.
any advice/help for me would be appreciated. I will check this thread periodically
