Created attachment 132831 [details] GPU crash dump Sorry, I'm a normal user, not a dev. I saw the template but I don't know how to look up chipset etc. and I don't have time to research. I'll provide required info if someone tells me exactly how to do it. I'm a reasonably competent user but I am NOT a graphics card expert nor do I have time to become one. syslog: Jul 22 11:59:45 dlm-E431 kernel: [ 93.675817] [drm] GPU HANG: ecode 7:0:0x86ffbff9, in Xorg [1195], reason: Hang on render ring, action: reset Jul 22 11:59:45 dlm-E431 kernel: [ 93.675818] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.

Lost HW context, needs a kernel update to circa 4.9 iirc.
Ah, OK, thanks. It turns out that an update to kernel 4.10.0-27 is available (maybe was available for some time, but the software updater didn't pop up so I didn't know about it). So I've updated and I guess that will take care of it. Thanks for the info -- otherwise I would have assumed I'm up to date. James
