[PlanetCCRMA] System slowing down with Ardour FC4/edge-kernel (softirq-tasklet)

[chromdildo]

Hello again,

Did some trial'n error and figured out, that all my problems surrounding
"xinerama"...
Turning Xinerama "off" solves the hight cpu-load of  "softirq-tasklet".
But with Xinerama "off" I get 2 independent X-Screens instead of one.

=> using latest binary nvidia drivers (1.0-7667) (tried olders with same
effect)
(I don't know how to set up a dualhead with fedora stock-driver "nv")

Anyone using dualhead with nvidia, too?


Thank you for pointing me the right direction Fernando...

best regards
./chrom
