Hi,
When system comes back from suspend to ram, I get a black screen with a mouse. Does not respond. I have to ctrl-alt-f1 to get a terminal, and back to F7. Once it worked, another time it did not. I had to kill xscreensaver to get a display. But touchpad mouse had disappeared from sight. Again to console and back, mouse was restored.
On hibernate to disk there are no issues.
Machine is Intel cpu and graphics, not recent make.
"Pentium(R) Dual-Core CPU T4300 @ 2.10GHz"
Model: "Intel Mobile 4 Series Chipset Integrated Graphics Controller" Device: pci 0x2a43 "Mobile 4 Series Chipset Integrated Graphics Controller" SubVendor: pci 0x103c "Hewlett-Packard Company"
Driver: "i915" Driver Modules: "drm"
I've had some suspend to RAM and other instability problems with i915 as well. Adding |i915.semaphores|to the kernel's boot parameters solved a lot:
My problem seems to be related solely to xscreensaver not responding to keyboard or mouse. But I can try your suggestions.
/i915.semaphores=1/
Also (for screen tearing issues):
|/etc/X11/xorg.conf.d/20-intel.conf|:
/Section "Device"// // Identifier "Intel Graphics"// // Driver "intel"// // Option "TearFree" "true"// // Option "AccelMethod" "uxa"// //EndSection/
If your system has two graphics chips (nVidia Optimus hardware) then also blacklist nouveau, in file /etc/modprobe.d/50-blacklist.conf add:
No, only intel graphics. Intentionally so. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)
