i have hanging problem of the viewer not the system i mean if i am playing music i still hear it playing , but the screen is freezed on one scene , many times , when i use
Code:
youtube-dl <link to youtube video>
so i press Ctrl + Alt+F1 then i press Ctrl +Del+Alt to restart normally and start again

is there anyway to use Alt+Ctrl+F1 to restart the viewer and then press Ctrl + Alt+F7 to get it again without restarting from beginning ?

any suggestions
