I’ve been banging my head against this for the last couple of months on and off (various versions of 304, X and kernel)
hardware: Generic desktop PC (Intel DQ35JO board/Q6600/8Gb) Qudaro NVS 440 card.
Even though the system has the latest version of Xrandr, “xrandr --listproviders” only shows one GPU.
X logs make it clear that both GPUs on the card are being picked up.
The only way to get 4-headed X working is to enable Xinerama, which comes with significant performance penalties and disables Xrandr - which in turn means quite a few programs refuse to start.
I’ve been assuming that I’ve been missing something in the configuration, however there have been hints of a Xrandr bug in latest versions of X or the nvidia driver. Can anyone help out either way with confirmation?
Bug reports with and without Xinerama attached.
Thanks in advance.
