No refresh rates were reported by your X Display Server. If you are running a nested X Display Server, then this is to be expected. However, if you are not, then the current refresh rate will be used when setting the resolution, which may cause damage to your screen.V Xorg.log je záznam, který vypadá že by mohl souviset:

Původně monitor fungoval tak, jak měl, nicméně šéfovi se podařilo odpálit desku, a když si pak objednal nový kus, fungovat to přestalo (s tím samým systémem).

Kde dělám chybu? Tu detekci bych oželel, stačilo by mi moct si při startu zařízení nastavit rozlišení právě třeba v xorg.conf
