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.
