[Confused] Ubuntu GUI injury?

To be honest, the Ubuntu GUI looks really good, but there are also a lot of problems, and stability is really unpleasant. Recently, I have encountered a NetworManager management problem!

I believe someone has met me!

Ubuntu netwok-manager the system network services are not compatible with this version

There is also the problem with the graphics card driver that I encountered last time:

Some solutions have been found on the Internet, such as link and link2, but various dependent packages need to be downloaded. I don't want to download it, and his system is 12.04 different from mine.

When I install other software, the dependency is resolved as follows:
