High pitched noise after installing ATI graphics drivers
First: Yes, I did see the other thread with almost the exact same name, but his noise would disappear when turning the volume down so I guess it's different.
So, the problem is this... I recently wiped my harddrive clean due to stupid partition problems, and I installed Xubuntu 8.10 yesterday. I downloaded a game, which lagged really bad, which was strange, this laptop being new and all(Acer Aspire 5530). After doing some reading this way and that way I discovered I wasn't using my graphics card at all(ATI Radeon HD3200) due to not having drivers for it. I thought that was stupid, so I went to ATI's homepage and downloaded "ATI Catalyst™ 9.2 Proprietary Linux x86 Display Driver". After a bit of hassle with running the .run file(I'm a newbie) it seemed to install fine, and I rebooted. Then came the annoying sound. It's very high pitched but not very loud. It's not coming from the speakers, i tried turning ALL the sliders down is the volume control with no effect. I can hear it more clearly if I put my ear to the bottom of the computer, not especially clearly with my ear against the speakers.
If I close the lid(So that the display is turned off) the sound stops. Also, whenever the computer is actually doing something, like scrolling, playing a game, anything really, the sound gets all broken up and when playing a game it's almost quiet. The sound doesn't appear until you reach the login-screen at boot. I guess that's all the info I can give. I hope someone knows a solution. I can't sit with this computer in class, it would annoy the hell out of everyone within a five-metre radius...
