<div dir="ltr"><div><div>Hi, </div> 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 <a href="https://cgit.freedesktop.org/~airlied/linux/log/?h=drm-next" target="_blank">https://cgit.freedesktop.org/~airlied/linux/log/?h=drm-next</a> 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... </div><div>Regards, </div><div>Vincent Vanackère </div><div><div> [ 1.199135] nouveau 0000:01:00.0: NVIDIA GK208B (b06070b1) [ 1.319930] nouveau 0000:01:00.0: bios: version 80.28.92.00.10 [ 1.322095] nouveau 0000:01:00.0: fb: 2048 MiB DDR3 [ 2.620362] nouveau 0000:01:00.0: DRM: VRAM: 2048 MiB [ 2.620362] nouveau 0000:01:00.0: DRM: GART: 1048576 MiB [ 2.620364] nouveau 0000:01:00.0: DRM: TMDS table version 2.0 [ 2.620378] nouveau 0000:01:00.0: DRM: DCB version 4.0 [ 2.620379] nouveau 0000:01:00.0: DRM: DCB outp 00: 01000f02 00020030 [ 2.620380] nouveau 0000:01:00.0: DRM: DCB outp 01: 02011f62 00020010 [ 2.620380] nouveau 0000:01:00.0: DRM: DCB outp 02: 02022f10 00000000 [ 2.620381] nouveau 0000:01:00.0: DRM: DCB conn 00: 00001031 [ 2.620381] nouveau 0000:01:00.0: DRM: DCB conn 01: 00002161 [ 2.620382] nouveau 0000:01:00.0: DRM: DCB conn 02: 00000200 [ 2.666199] nouveau 0000:01:00.0: hwmon_device_register() is deprecated.
