Hi there.
I think I can help on a couple of your problems.
1. With the sound issue, try typing `alsactl store` after changing your volume. So far, it's worked for me.
2. I'm not an expert on mice in linux, but since I'm running Slack 9.1, I'll tell you what I did to get my scroll wheel working. Under the "InputDevice" section of XF86Config where your mouse is, use "imps/2" as the protocol. Then set the zaxismapping of the mouse. Here's what it should look like:
Code:
Option "Protocol" "imps/2"
...
Option "ZAxisMapping" "4 5"
The "..." indicates other options that may be after the protocol option.
3. I have no idea about the <> problem. Sorry.
Hope this helps a little! :-)
