I just rebuilt an old acer x1700 and I installed a new Radeon 5450. I am no longer using the stock windows vista. I installed Ubuntu Quantal for my os and now I am having trouble with the sound...there is none. I recieved a cd for installing the drivers but it was not for linux, only windows. I am assuming it is using open source drivers from unbuntu...how do i install the proprietary drivers and enable sound? Once I get past this hurdle I should be great. Btw this is my first pc rebuild and I am also new to linux. It would be nice if i had friends I could ask to help...but i have no such thing. Thanks in advance.
OS: ubuntu quantal (12.10)
Video card: xfx one radeon 5450
Solved my own problem. Just follow the instructions below if you have similar issues.
Using Ubuntu-supplied fglrx/Catalyst
On Ubuntu Quantal, this will install fglrx/Catalyst 9.000, which is roughly equivalent to Catalyst 12-9. NOTE: You must have the restricted repository enabled in Applications -> Software Sources... for this to work. After you complete the install, skip to Generate a new /etc/X11/xorg.conf file.
Jockey was removed in 12.10. You now need to go to Software Sources and go to the Additional Hardware tab. You will need to install linux-headers-generic beforehand, or the Panel won't show up after the restart.
I recommend copying and pasting the commands to ensure there are no typing mistakes and speed up the install process. Remember to use Ctrl + Shift + V or Shift + Insert to paste into the terminal (or go to the terminals menu, select edit and click paste).
Before you start
If you have previously attempted installing Catalyst, remove any leftover files by following the Removing the Driver section. Make sure universe and multiverse are enabled in your repository sources (System -> Administration -> Software Sources). or Applications->Ubuntu Software Center->Edit->Software sources->Other software: check canonical partners.
NOTE: if you don't reboot first, fglrxinfo gives an error message. Reboot the computer and type
into the terminal. If the vendor string contains ATI, you have installed the driver successfully. Using fglrxinfo on a system with Catalyst 12-3 and a RadeonHD 4550 returns:
display: :0.0 screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: ATI Radeon HD 4550 (This line may be different depending on what graphics card you are using.)
OpenGL version string: 3.3.11566 Compatibility Profile Context (This line may be different depending on what graphics card and
Catalyst version you are using.)
If you experience issues or a hang, you may need to disable fast TLS.
