sudo service lightdm restartpak pust x11vnc znovu, tentokrat/prozatim bez parametru
x11vncmelo by to skoncit timto (a zustat bezet):
One can also add -ncache_cr for smooth 'copyrect' window motion. More info: http://www.karlrunge.com/x11vnc/faq.html#faq-client-cachingpak se zkus pripojit VNC klientem a podivej se co/jestli x11vnc vypsalo(a postni to sem), pokud to prijimalo spojeni z tveho vnc klienta a neco by se podelalo tak x11vnc by se ukoncilo (bez parametru je pousteno "na jedno pouziti"), a pred dalsim pokusem o VNC spojeni musis x11vnc zase pusitt, pripadne ho pust aspon s parametrem "bez naporad"
x11vnc -foreverjinak zamek si zrus v "Nastaveni/Jas a zamykani" (snad staci tam)...
