I have just installed ubuntu 11.10 oneiric on my dell studio 1569. I am experiencing a strange problem with brightness control, volume control etc: my hotkeys are enabled and, apparently, when I use them the indicator of volume and brightness changes. Same result when i manually change brightness and volume. But to the change in the indicator does not correspond any change in the effective brightness and volume. Any idea about what can I do?
thanks a lot, /matteo
