Hi, I’m something new to Linux and don’t know a lot of things.
The things are like this, I bought a new laptop with windows Vista, but installed openSUSE on it, almost everything works fine but a pair of things:
+I have problems when I try to use headphones as I can’t hear anything in them but they are detected as the integrated speakers go mute. This is a big problem when I go to the library. I have already tried putting al the channels in the ALSA mixer to 100% but nothing
+The mouse pad acts weird so I must use an external mouse

I would greatly appreciate some help with this. Thanks

PD: sorry if I mix wrongly some words, I’m not English spoken.

Which version of of Open SUSE do u have??? maybe u can try a version upgrade
