Today I updated one of my work machines to the Ubunt 18.04 LTS. Most
probably I will have to update it to the 20.04 at least but Ubuntu
updates have to be done in steps.
The machine in question is an old Lenovo x61s. The laptop I used for
years for important tasks but now it is quite old and well used. Now it
serves as a TeX/Octave/XFig machine. Anyway, it is still capable to
drive my 24" EIZO screen (1920x1080). I am sure that it has still a
plenty of power for this type of use.
The upgrade was quite smooth. The only problem was that it replaced the
Unity with the GNOME desktop. Not only it is slow but it is also
somewhat unfriendly and unintuitive. So I have had to install the MATE.
The whole process probably took a few hours. I'm not sure how much as I
worked on the machine during this time and almost forgot that I am
upgrading it... Of course, this is not the best practice but this time
it worked.
