Hardware info? Is it a fresh install or an "upgrade"? Did you post on the help threads?The last straw for me has been the complete uselessness of what is supposed to be a Long Term Support release, 14.04. My desktop crashes periodically, weird things happen such as icons disappearing and Unity freezing. It won't let me install the proprietry Radeon Mobility drivers, which means my display suffers from lag and jerkiness. In order for me to have a stable system I would have to go all the way back to 9.10.
There are some minor glitches (such is the case of ALL new OS releases) but nothing major. In fact I think the quality of new releases are getting better and better since the time of 10.04. The new releases are less buggy and the bugs get fixed faster. I remember the state of 10.04 and 12.04 when they were released. I can easily use 14.04 as my main OS now if I overlook a few minor wrinkles, but 13.10 is working perfectly without even the small wrinkles, so I can wait til 184.108.40.206 when the remaining wrinkles are ironed out. But I would never have used 12.04 or 10.04 before even the end of April.
Oh in your opinion, in your opinion. Who are you to declare x "is a mistake"? Sounds rather pompous to me. Many of us happen to like Unity.Unity was a mistake.
