Red Hat Bugzilla – Bug 229201
Touchpad does not work after resume from suspend to ram
Last modified: 2008-02-07 23:24:08 EST
Suspend to RAM works, but after resume, the keyboard and touchpad to not work
(i.e., do not respond anymore). I can login via ssh and use an external USB
mouse alright, so the laptop has not crashed. If I execute kbdrate after resume,
the keyboard works again, but not the touchpad. I tried to build the kernel with
i8042 as a module, so that it can be unloaded before suspending, but I did not
succeed (some strange configuration errors).

dmesg output after resume
I think I suffer from the same bug (see below my description).
Note : I do NOT have this problem with kernel-2.6.18-1.2869.fc6.i686
The problem APPEARED with kernel-2.6.19-1.2895.fc6.i686.rpm
and is STILL there in kernel-2.6.19-1.2911.fc6.i686
Description of the bug :
After a resume (from a suspend to ram) :
- I find that the keyboard modifers are set in weird way : for example, Scroll
Lock is ON. If I play with Caps Lock, I manage to get the keyboard working
- the touchpad doesn't work anymore (and I found no way to get it back working)
- my USB mount still works OK (fortunately)
Above is the output of dmesg after resume.
Mistake in the former post :
"my USB mount" -> "my USB mouse"
the situation has gotten worse after an update to kernel-2.6.20-1.2925.fc6
Now the keyboard is totally locked after a resume. I am not able to do
Ctrl-Alt-F1 to get a console. The USB mouse still works and programs react
normally to the USB mouse clicks. However, nothing happens with the keyboard or
On the "resume", I read on the text screen : "i8042 : failed to resume active
multiplexor, mouse won't work" ... in fact, both the touchpad and the keyboard
don't work. USB mouse works.
(and to the same time, the update broke my ndiswrapper... this really sucks...
what's the point of these "yum update" if they brake everything !)
Is there any solution for this problem ?
It's even worse with kernel-2.6.20-1.2933.fc6. Resume is now completely broken,
i.e., no resume at all.
