Question

linux

I ran into a problem that after installing Linux (I tried kubuntu 16.04 lts, ​​17.04, ubuntu 16.04 lts), the mouse, the Internet (by cable through the router, I also inserted the cable directly, the effect is the same!) And non-native resolution on the screen is. Although during the installation everything works and the mouse does not, and the resolution of the norms is worth it. Installed through unetbutin. I tried to install Windows 7, got up normally and everything worked.
