Hi,after i installed (with a lot of terminal work) the driver for nvidia i recognized some issues.

1. The mouse and keyboard are not working after login. I mean they work properly on grub, (i have a autologin) but when cinnamon appear they don't work until i unplug and replug the usb-dongle. When i replug the usb the mouse and keyboard works fine! ...verry strange i know!

2. The Sound don't work. On the small icon for sound in the bar/panel i get "Output Device" --> "Dummy output" Before the install there was written something else and the sound works properly

3. My NTFS - Disk are not mounted automatically as before. OK for that i made some change on fstab and i can now look into making some links etc. but before it was shown automatically on the Desktop.

I am looking something like how to autoconfigure everything or only Sound and mouse/keyboard.

Am not sure, but i faced similar issue of my trackpad and keyboard not working. Probably, your xorg.conf file is corrupted.

Can you post the specs of your Nvidia Graphics card? If it is Optmius and you have another Intel Chip, then you may have to install bumblebee after purging the existing Nvidia drivers to get it working.

thanx!i hope this will help!i have to say that nvidia-xconfig & nvidia-settings wasn't installed on my system. ???...and now i will reboot hoping something will be different! speaking about the mouse- and sound-issue described before.
