I have a Dell Latitude E7240 as my work machine. It came with Ubuntu 12.04 pre-installed. I would like to upgrade to a later distro but it is important that I don't end up witha buggy machine a s a result.
Has anyone with a factory version of 12.04 dist-upgraded who can comment on it? Has it caused you any issues? Did you go to 14.04 or another distro? Do you use a docking station and does this work?
Are the Dell utilities overwritten or do they remain intact?
