I hope to chenge colour or the theme but can not get it done ...

[fossiili]

I usually let the Linux-distribution to keep the look it has after the installation. But now I hope to have LinuxLite to look differently.  I have tryed to change the theme but nothing happens.

Should I edit X-configuration files or what? Any terminal command?

What information is needed. I now have the problem to remember the  command to get informatin of the computer.

I appreciate any help you will be giving
