So what status of issues you submitted in current driver? I mean does it still reproducible in Catalyst 12.10-12.11?
This bug was submitted to nVidia tech. support in August, but in 313 driver release still doesn't fixed.
Thanks for the writeup Datenwolf, appreciate it a lot.
So do you think I would have more success with a multi gpu setup of the same family? I've also been reading into using the Eyefinity display ports on my 7850. I was looking at trying to use the 7850 for everything. HDMI for the TV, 2x mini display port to DVI adapters and the last DVI port.
The only way to use multi-GPU multi-display is with zaphod mode and optionally xinerama if you want all the displays to act as one big desktop. The xserver still supports zaphod mode and xinerama. Basically no one has written to the code yet to support this in X like it is in windows. The prime/hotplug stuff Dave recently landed in the latest xserver lays the groundwork, but it has not yet been extended to support multi-GPU multi-display. Finishing that would be a good project for someone looking to get a deep understanding of xserver internals.
I finally documented and submitted my crash to AMD. See here:
I got the open source driver to work somewhat with radeonsi and glamor, but it still crashes when I try to use xrandr to rotate a monitor into portrait orientation.
Ah, the downsides of the GPL license...As it turns out, today's hardware is perfectly capable of doing this. It's just that the current Linux graphics driver model doesn't support it. And unfortunately those functions required to support it (DMA-BUF) have been locked down to GPL only, which means NVidia will probably never support it.
