I forgot to mention, it's a Samsung Series 7 Ultra laptop, NP730U3E.

Comment 2 Edouard Bourguignon 2013-07-05 19:24:52 UTC
Same problem on Fedora 19 and Samsung NP740.

The patch is here https://launchpadlibrarian.net/142425881/0001-elantech-fix-for-newer-hardware-versions-v7.patch

Works fine.

BTW, why psmouse support is not build as a kernel module? I have no choice to rebuild complete kernel to add this patch, it works but a simple dkms should be more efficient. Other distros psmouse is a kernel module.

Comment 3 Edouard Bourguignon 2013-07-27 15:27:09 UTC
Any news? Ubuntu has just released the fixed on their kernels. Patch will be upstream for 3.11 I think:

Comment 4 Edouard Bourguignon 2013-07-27 15:28:00 UTC
This bug affects at least laptops from Acer, Gigabyte and Samsung.

Comment 5 Josh Boyer 2013-07-29 12:30:57 UTC
Thanks again for the pointer.  I had emailed Matteo about sending the patch upstream earlier in the month.  I'm glad to see that happened.

I've applied the patch to F18 and F19.  Rawhide should already have it.
