Hi, I own an Asus GT730-SL-2GD3-BRK, trying to drive two monitors at 2560x1440 resolution. Using gnome-shell with either Xorg or wayland I get screen freezes very frequently. Those freezes usually require a reboot to get working graphics (below a sample trace that I got yesterday). I am running Ubuntu 17.04 with the latest kernels avalable, I also tested various more recent kernels including the latest drm tree at https://cgit.freedesktop.org/~airlied/linux/log/?h=drm-next but the problem always occurs. When a freeze occurs, the computer is still reachable through ssh but the only action I found so far to get graphics back is to restart the computer. I am willing to run diagnostics programs or test any patch if it would help. I'm also not excluding the possibility that I may have some faulty hardware so any hardwae-health-test advice would be welcome...
