I can use the keys to go to a console session to do a dmesg, whose last lines read: [drm] stuck on render ring [drm] GPU HANG: ecode 0:0x00dff888, in Xorg [751], reason: Ring hung, action: reset [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.

a.m.wink@gmail.com - I'm really sorry about this looong delay until getting back to you. Do still see this problem, preferable on newer kernel (compiled from drm-tip) ?
It did not reload the aliasing-ppgtt after resume.
I still have the result that if the screen goes black, eg. when the battery is about to die, and if I rescue it by plugging it in, mouse and keyboard are unresponsive as before. Have not looked at the error messages but still using kernel 3.16.0-4-amd64 #1 SMP Debian 3.16.39-1+deb8u1 (2017-02-22) Could you please direct me to that update and how to make sure that it's installed? Really happy to help solve this.
You need to jump forward about 3 years of kernel/driver development to v4.9+
Well my post was from last year -- the problem was definitely there then. RE versions, this is what I have server glx version string: 1.4 client glx version string: 1.4 GLX version: 1.4 OpenGL core profile version string: 4.3 (Core Profile) Mesa 12.0.3 OpenGL core profile shading language version string: 4.30 OpenGL version string: 3.0 Mesa 12.0.3 OpenGL shading language version string: 1.30 OpenGL ES profile version string: OpenGL ES 3.1 Mesa 12.0.3 OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.10 and I do a regular apt-get upgrade.
Please look into upgrading to the kernel, and preferrably other graphics stack components, from jessie-backports. The kernel version on jessie-backports is v4.9. Closing the bug. Please reopen if the problem persists on v4.9. Thanks.
