Description of problem: Elantech synaptics touchpad works but is not recognized as such, so synclient isn't able to change options.

This is a kernel issue. The newer elantech touchpads don't seem to work correctly with the current driver and stay in the mouse emulation mode. We don't have a fix for this yet, afaik.
It looks like some patches are available: https://bugzilla.novell.com/show_bug.cgi?id=558225#c4 http://www.spinics.net/lists/linux-input/msg08277.html
This looks like a duplicate of #549065
The fixes from comment #3 are in kernel-2.6.34, which will be available for F-13 soon.
I'm running F13 with 2.6.34.3-37.fc13.x86_64 from updates-testing. The Elantech trackpad is still recognized as a Logitech ps/2 mouse.

Same here on 2.6.34.1-29.fc13.x86_64: synclient -l Couldn't find synaptics properties. No synaptics driver loaded? Is there some additional things to do other than upgrading the kernel? Are only some models supported?
Not sure. I think the synaptics driver never loads as it thinks there is no touchpad present, but it would load if the touchpad was detected correctly. I also tried this that I found on some forums, connected to kernel 2.6.34: echo "options psmouse force_elantech=1" | sudo tee -a /etc/modprobe.d/psmouse.conf which to my limited understanding should tell psmouse module to assume that what it found is an "Elantech" no matter what the detection comes up with but that didn't change a thing for me. There was also mentioned to "rmmod psmouse && modprobe psmouse" but this was refused by my system as: rmmod psmouse ERROR: Module psmouse does not exist in /proc/modules or "modprobe -r psmouse && modprobe -v psmouse" refused as: modprobe -r psmouse FATAL: Module psmouse is builtin As my knowledge is limited, I hope someone that really knows stuff chimes in. Not sure if kernel options or blacklist would help. I am considering blacklisting something at boot, the way they load proprietary graphics drivers.

And there came the knowledge I was short of :-) Adding "psmouse.force_elantech=1" to the kernel command line did identify the touchpad as a touchpad and the proper drivers are loaded. I guess this is still a bug as the detection is not working correctly but this is a usable workaround. F13 with kernel 2.6.34.1-29.fc13.x86_64 from repo updates-testing on an Asus UL50VT with Elantech touchpad.

Yes, as Chuck Ebbert wrote(In reply to comment #11) > (In reply to comment #9) > > Since psmouse is built in, you would need to add "psmouse.force_elantech=1" to > > the kernel command line instead. > > I created a file: > /etc/modprobe.d/psmouse.conf > with this contents: > options psmouse force_elantech=1 > > But it doesn't work... anything else I can try? Yes, as stated in comment #9, you would need to add "psmouse.force_elantech=1" to the kernel command line. That means editing /boot/grub/grub.conf OR editing the corresponding line in the menu before boot if you just do this once to test it. The grub menu entries look like this: title Fedora (2.6.34.3-37.fc13.x86_64) root (hd0,0) kernel /vmlinuz-2.6.34.3-37.fc13.x86_64 psmouse.force_elantech=1 initrd /initramfs-2.6.34.3-37.fc13.x86_64.img Where I've inserted "psmouse.force_elantech=1". However, you probably need to run a kernel 2.6.34 or above for this option to work. I would suggest that you wait a few days for kernel 2.6.34 to mature. I tried 2.6.34.3-37.fc13.x86_64 yesterday from repo updates-testing and it crashed to often to be useful.
(In reply to comment #12) > Yes, as stated in comment #9, you would need to add "psmouse.force_elantech=1" > to the kernel command line. You're right. I thought that the options in modprode.d conf files where valid also for components compiled in the kernel. On the contrary they work only for modules. So this is fixed in kernel 2.6.34 if using "psmouse.force_elantech=1".
Ok, tried Fedora 14 alpha (kernel 2.6.35-rc6) and it worked without using the force_elantech=1 parameter. So the complete fix is in 2.6.35 and the partial (requires additional manual kernel parameter) is in 2.6.34.
