I have an Acer Aspire V5 that came with windows 8. Now I have the Ubuntu 12.10, 32 bits.
First, the command to dim or brighten the screen with -Fn up or down- is acting on the screen (it shows that it is dimming or increasing on the bar on the screen), but the screen doesn't do so.
Second, my computer is a touchscreen, still working with Ubuntu, but seems to be buggy a little bit from time to time. For example, it is supposed to be a one-finger scroll up or down. It acts like it on PDF files but not on the Internet. I cannot find anywhere in Ubuntu how to program the settings of the touchscreen. Are there any programs to download to do so, or is touchscreen support not in Ubuntu yet? It also goes nuts (not frequently, but still...) as it closes the tabs or goes to the Ubuntu purple page that shows the crypting things when I start my computer. Then it goes right back to where I was on my page as if nothing had happened.
Last of all, my computer suddenly lost the Web cam when I am using Skype. The in-build cam in the laptop shows me a green light beside the cam but the video is all black. Cannot see anything. This has happened two days ago and cannot understand why since it has been working since I got with Ubuntu.
Those are my concerns. If anyone could help that would be much appreciated.
