Tän blogin tarkoitus oli alkujaan että julkaisen vain Linux aiheita, mutta tuule tuulevat ja maailma muuttuu. Tällä hetkelläkin käännän lähdekoodista Raspberry Pi:lle ohjelmaa, eli siis Linuxille. No tämä oli tällainen aasinsilta :D. Eli Mun työ piste koostuu 4:stä näytöstä Facebookissa osa on jo nähneetkin viritelmän. Mutta siis 24" näyttö oli tarkoitus valjastaa myös Raspberry Pi:lle HDMI kaapelia pitkin, sillä HDMI+VGA ei toiminut ja näytössäni on HDMI portti myös.
Tämä tarkoitti käytönnössä sitä että ensin kokeilemalla kokeilin miten toimii, no se toimi mutta resoluutio väärä eli ei 1920x1200. SD-kortilla on boot osio jossa on tiedosto nimeltään:
.
Ja ota # merkit pois edestä.
Omalla kohdallani hdmi_group=2 ja hdmi_mode=68.
Omalla näytöllä Benq 24" G2400W.
Siis näyttää tältä: (oleellisin lopussa lihavoituna).
