Since User Interface in Ubuntu was changed to Unity, in 2011, my problems with video driver began. From that time it has been difficult to use the Canonical's operating system in my work computer.
I might be wrong, but it seems that there is no determination of the development team in creating a robust driver software.
The U.I. Unity is good, really good, but it's integration with NVidia driver is a complete disaster.
Nouveau driver (open source) seems to have been abandoned and the proprietary drivers have serious problems that are never solved. Year after year, version after version.
Starting from installation, the boot via pen drive presents a screen flickering, corrupted, where the image appears blurred and cut vertically. The installation process must be run this way, unable to read information on the screen, until we can set a resolution that the image is stable and readable. An adventure!
Once you get the driver change, other problems start to happen, making it impossible to use Ubuntu.
The issues are more frequent with LibreOffice, but sometimes occur in Chromium, pgAdmin and others.
Problems with NVidia Video Driver in Ubuntu 12.10 are so serious that I was forced to install the 13.04 alpha, but there was no significant improvement.
Finally I need to know if there is any chance of this serious problem be solved and whether there will be a video driver NVidia that does not cause so many errors.
