From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; pl-PL; rv:1.8.0.8) Gecko/20061107 Fedora/1.5.0.8-1.fc6 Firefox/1.5.0.8 Description of problem: After my laptop hp nx6310 is woken up from suspend to ram the touchpad won't work. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. put laptop to sleep (echo mem >/sys/power/state or by menu in gnome-power-properites applet) 2. wake it up Actual Results: touchpad does not work. can't move cursor nor click. keyboard works. after reboot everything is ok. Expected Results: touchpad should work. Additional info: i though it may be relevant to so called "bad state" in hp notebooks so i recompiled standard i686 kernel (2.6.18-1.2849, from src.rpm) with psmouse switched to build as module (that was the only change). then, after laptop was woken up, i tried to reload psmouse (modprobe -r psmouse; modprobe psmouse) and touchpad started to work but all special features such as tap for click, double tap for drag, vertical scroll, etc, were gone. so i was only able to move cursor with touchpad and use buttons, but it's not so comfortable as using taps, scrolls, etc.
Could you please try adding i8042.reset=1 to the kernel command line? Reassigning to me as it looks more like a kernel driver issue.
*** Bug 187098 has been marked as a duplicate of this bug. ***
Somebody suggested in bug 187098 that this might have upstream in http://bugzilla.kernel.org/show_bug.cgi?id=7977. I am not that much involved in kernel stuff, but he is IMHO right.
I'm suffering with almost this same issue in the F9 Beta/Rawhide on my Asus F3SR with Synaptics touchpad. Though I didn't notice it until I changed some synaptics driver options away from the defaults. What happens for me is that when I resume from S3 suspend, all the synaptics options I've changed in xorg.conf seem to be ignored. Output from "synclient -l" indicates that my settings were read correctly from xorg.conf, but behaviour has reverted back to the default. Setting options with synclient no longer works after resuming. Restarting X with a Ctrl-Alt-Bkspc fixes the problem. My xorg.conf contains: Section "ServerLayout" ... etc ... InputDevice "TouchPad" "CorePointer" EndSection Section "InputDevice" Driver "synaptics" Identifier "TouchPad" Option "Protocol" "auto-dev" Option "TapButton1" "1" Option "RTCornerButton" "2" Option "RBCornerButton" "3" Option "SHMConfig" "on" EndSection See attached Xorg.log I tried adding "i8042.reset=1" to the kernel command line as suggested in comment 1. The problem still persists, only now I get a "An internal system error has occurred" popup when I resume from the suspended state. :-)
