Just as the subject says. Ive messed around with my xorg.conf trying to get compiz fusion to play nicely with video playback. I followed the instructions on http://forum.compiz-fusion.org/showthread.php?t=6794
I removed fglrx-driver and compiz-gnome and removed the xorg.conf from /etc/X11/xorg.conf . After running sudo dpkg-reconfigure -phigh xserver-xorg . And whe X is restarted usb support is gone (will not recognize usb devices. (the light does not blink) and my wired nic is not detected. (eth0) Huge thank you goes to the person who can fix this I'm close to doing re-installation and loosing my data.
