(I’m using what is probably the most recent Haiku driver for this, but on R5)
I’ve got an odd problem, where the Matrox driver is selecting my secondary output on a G550 PCI-E as BeOS’s primary - this means that with a single monitor, I can see either the BIOS and bootman; or see BeOS.
None of the Dualhead Setup options seem to be of complete use - Switch Head does switch heads but leaves me with an extended desktop across a non existent monitor; Clone Head leaves me with the cloned desktop on my primary output - so no cursor due to the driver using a hard cursor on monitor 1.
Can anyone remember if they had this before and if there is a fix? Other than wiring the second output up and switching between them on the monitor, which I could do but is rather faffy!
