Thread: 2 gfx cards, 4 monitors fails X fail cycles

i have 2 nvidia gfx cards, if use nvidia settings tool view 2 monitors same gfx card works fine, when use 1 gfx card 1 monitor , other gfx card other monitor x doesnt start , cycles through monitor flashes.

idea problem?

the nvidia proprietary driver provides no mechanism drive more 2 monitors on 1 x-screen

nvidia can address

do, however, have options

1) seperate x-screens

run 2 x-screens
each x-screen uses 2 monitors (with nvidia's twinview)
2 x-screens separate (you cannot drag windows between them)

each x-screen (should) able 3d acceleration


2) xinerama
xinerama created ages ago, , provides way chain arbitrary number of screens together

xinerama long pre-dates 3d graphical acceleration, have no desktop effects

xinerama being phased out, in favour of randr (a more modern equivalent)

nvidia has poor track record randr support, though


3) use nouveau
