Webkamera
Mam zaujem si kupit nejaku webkameru. Avsak neviem aku, pretoze neviem ktore su funkcne pod linuxom a maju funkcny ovladac. Viete mi niekto poradit dobru funkcnu webkameru, ktora sa da jednoducho rozbehat? Mam jedine tu T-com... ktora je absolutne dodavana k internetu zadarmo a pod linuxom nefunguje, z funkcnosti je iba v svietivost v noci (co je absolutna katastrofa), tak uz odcestovala na windowsovy pocitac.

viacej vid. man :D
ja tiez dufam ze vydanie visty a uvedenie asus eee znamenali zaciatok konca dominancie windows
Aj ja dúfam, že dominancia blbosti sa aspoň trochu zníži (windowsi, hlúpe patenty napríklad dvojklik)
Dvojklik vo Windowse sa dá nadstaviť aby si klikal iba 1x a iste sa bude dlho držať Windows na trhu ako dominant lebo zmagorili ľudí. Veľké masy ľudí si žiaľ myslia, že na svete niet iný operačný systém.
Kupil som si web kameru Trust WB-3250, no a problem je v tom, ze nefunguje ;) Aj ked to vyzera tak ze system vie o co sa jedna:
vypis dmesg | tail po pripojeni :
