Updating Your System Files And Drivers
Update Your System
Within roughly five minutes, the Update Manager will appear and automatically search for updates. Once opened, it may take a few moments for the Update Manager to find all available updates. When it has finished, click Install Updates.
Note: If you chose 8.04 LTS instead of 9.04, a red downward-pointing arrow should appear in the notification area. This is the symbol for critical updates, while non-critical updates appear as an orange sunburst. Click on the red arrow to open the Update Manager if it hasn't already opened yet.
The screen will shade and you will be prompted to enter your password. This will happen every time you do an activity that requires changes to be made to system files.
When the updates are finished installing, click the user/power button in the far right of the upper panel and then choose Restart.
Activate Proprietary Drivers
When your computer restarts, get back into the desktop. If an “add-in card” icon doesn't appear in the notification area within a few minutes, click the System menu. Go to Administration and then click Hardware Drivers.
Since Ubuntu 9.04 is still so fresh, new proprietary drivers may not be available, in which case you do not have to do anything at this stage. When AMD, Intel, or Nvidia releases new drivers for your video card, this is where you'll go to enable them.
If, by the time you read this, there are new proprietary drivers available, select the one with the highest version number and then click Enable. After enabling new drivers, you must restart your system.
