3 weeks ago I bought an MSI Cx640 laptop - 2nd Gen Sandy Bridge cpu, USB
3 etc.
I'm running LinuxMint 11 (latest)
Problems:-
1) cant turn off touchpad - when using mouse, pointer/entered text jumps
all over the screen.
2) no audio from headphone/audio out port.
Excuse the long post, but here is info re system from both Mint and
Windows 7-

I've googled for 3 weeks with no working results.
Even the touchpad-indicator applet installs but doesnt work.
Re sound output - headphones work with Fuduntu 14-10-RC2-64 but at same
time as laptop spkrs - no option to turn either off.
--------------------------
I've tried the latest Ubuntu 11.04/Open Suse 11.4/Fedora 15/Super OS
Linux 11.04/Berry 1.10 Live CDs etc without luck.
------------------
Any advice appreciated. There must be file(s) that can be manually
edited to prevent the touchpad activating on boot, and ditto for sound.
I know these are the problems on gets when buying the latest hardware.
Thanks in advance
Bill - very frustrated.
