Created attachment 103913 [details] dmesg About every 3 suspend/resume cycles, my screen remains blank; I can still SSH into the machine. This is with an HP dv6 with an Intel Ironlake GPU (8086:0046) on Fedora 20. When this bug does not happen on resume, the desktop works fine except that the mouse cursor is not visible and that gnome-shell crashes (before restarting fine). Everything used to work fine when only using the VESA driver. Installing the Intel driver made the problem appear. This is a dual-GPU machine, the other card being an ATI Radeon, which is apparently turned off according to vgaswitcheroo: 0:IGD:+:Pwr:0000:00:02.0 1:DIS: :DynOff:0000:01:00.0 2:DIS-Audio: :Off:0000:01:00.1 A weird thing that I noticed is that the GNOME Screens panel shows two integrated displays, the second one of which is not visible. Please ask if you need any additional information. xorg-x11-server-Xorg-1.14.4-11 xorg-x11-drv-intel-2.21.15-7

Oh, and when I call poweroff, the Plymouth boot screen appears just fine.
Bump!
The actual crash may have been more informative - all that is shown here is some benign oddity in the dual-gpu config.
What do you mean by "the actual crash"? I took all the information I could after the screen turned black. But maybe there's no crash at all, just a bug with backlight?
"When this bug does not happen on resume, the desktop works fine except that the mouse cursor is not visible and that gnome-shell crashes" If that is a driver related crash, it may be more meaningful than that the kernel or UXA loses a vblank across resume.
OK, I'll try to debug the gnome-shell crash, but for now I don't have access to that machine anymore.
Any chance you can continue investigating with this machine?
Not at the moment. I'll reopen when/if I can get more information about the crash.
Thanks for the bug report. I am sorry we never made any progress on resolving the issue, so please do reopen if you ever get the chance!
