view story

http://ubuntuforums.org – Hi, Just couple of days before installed Ubuntu 12.04 with all the necessary upgradations. Also installed Compiz Settings Manager & loved the animations & wobble effects of windows. But after restarting windows today, started receiving error messages & Wobble effects are disappeared. Also, other settings created by me in my last login, like small sidebar icons, too disappeared & unable to find even option in "All Settings >> Appearance" to resize the icons. Loved Ubuntu 12.04, specially Animation & Wobble effects but unhappy with thes (Hardware)
