intel4000 + nvidia760 multiseat acceleration troubles: indirect intel rendering
after some days of hard work, my multiseat actually partially works! kinda.
some basic info
nvidia 760 and intel 4000 (motherboard+cpu) graphics
>i forget its exact name (crossfire?) but all my components support this intel+nvidia interaction.
some things i tried beforehand:
reinstalled drivers in general
swap "intel" with "i965"
almost every google-able guide to fixing intels direct rendering. im led to believe this specific form is caused nvidia-intel interactions.
the trouble now is that graphics are only running on the left side, the right side is using indirect rendering.
i cant find a suspect in my log or .conf's.
it gets stranger. KInfocenter reports that the left side is being accelerated with the intel card but is being run by the nvidia driver. in any case that side HAS opengl support and can run high-fps games as the nvidia card should do.
i jotted down what Kinfocenter is reporting, (the tool has no copy-paste functionality nor can i copy from the other side):
(the left nvidia 760 side)
nvidia 760's xorg.log.1
from the visual side, the intel side displays first, it shows the kde loading splash for a split second before the nvidia side starts up and the intel side goes blank, switching to tty7 (ctrl-alt-f7) will bring the intel side back up.
> to me this feels like the second the nvidia side starts up, and strips away intel's rendering. hence the reason to tty7 back to it
things im going to test after this post:
-if disabling the nvidia side will give the intel side direct rendering
-changes in what Kinfocenter is reporting when i start up the nvidia side only. intel side only.
-delete xorg.log.2 and make sure thats not recurring, or else i secretly have 3 desktops.
KDE is indeed acting up a bit, i am using 2 different accounts but nevertheless there are all sorts of tiny quirks. im not going to post about this until my graphics troubles go away first though.
Steam also denys to start on the nvidia side unless you copy-in the nvidia 32 bit libraries...
i could not get a fix so far
here's some extra info:
-the accelerator is "unknown" from the nivida side when i disable the intel side, but besides that there is no change and the nvidia side is still running fine.
