Ubuntu Installation :: Unmitigated Disaster - Logitech Cordless Keyboard Is Not Working

I have been a keen user of Ubuntu since version 7.something. In that time I have updated, upgraded, or done clean installs of each new versions usually about 2 months after the release to enable small bugs to iron out. There have always been minor issues usually easily rectified via this forum. However the 11.04 release is the worst I have ever come across almost forcing me back to winblows. So what is my gripe. -- 7 hours downloading and upgrading -- to obtain a system that does nothing -- nada. zip. it booted came to the desktop and nothing, Unity doesn't respond, no applications open, and the shutdown didn't work.

So -- downloaded the ISO this morning did a clean install and eagerly went into my new system. First issue -- my logitech cordless keyboard is not working, never had an issue before. so plug in a USB one, which is what I am using now. Go to the 'system settings' (took me a while to find where they had gone) but couldn't find anything in the keyboard section to allow me to configure a cordless keyboard. Failure 1

Open banshee and ask it to load the music library. It does, then click for a file to play and --- no sound! so choose another track just in case and banshee crashes, and the icon disappears from the unity bar. Failure 2 As usual I have an Nvidea graphics card so one of the first things is to install the proprietary driver. Never had an issue before. this time it loaded (apparently) and then I do the restart to enable it, and when I get back in there is no top bar, the Unity bar sits there and won't slide in and out, and no applications will respond. BIG failure 3

Re boot into recovery mode and opt for safe graphics mode. System re boots - Top bar now appears, Unity remains inoperative, and when I click the shutdown icon to get to system settings --- crash and burn system shuts down.-- BIG failure 4 Re boot into recovery mode (again) run "fix broken packages" DPKG runs for a while replacing and upgrading hundreds of packages. When finished reboot -- same issue desktop stuffed! Currently working off the live CD. To the developers -- maybe you are pushing ahead too quickly now. this sort of overall failure will lose more users than gain. I don't usually complain but as my title says for me Natty is an unmitigated disaster.
