(Resuelto) Problemas de visualización de Linux Lite Wellcome

[Francisco Luis Torres Yan]

I think the problem is that I upgraded Linux Lite 6.4 to Linux Lite 6.6, instead of doing a clean install.
What I'm going to try is a clean install from the Linux Lite 6.6 installation DVD. I already have a backup copy of the hard drive partition with Linux Lite. When I have everything installed and updated with Linux Lite Update, I will tell you the results using the commands that you have given me, for system information.
Of course, I will not add any repositories, except for the Ubuntu Pro ones that I have activated for my PC.
