Actually, neither starting syndaemon via rc.local nor enabling SHMconfig in xorg.conf helped. The only way to disable touchpad while typing was to start syndaemon from a graphic session as a user. The button to disable touchpad does not work and the "disable touchpad while typing" checkbox in system control panel has no effect as per my original report.

The button to disable touchpad does not work as well. As a workaround I use "syndaemon -i 1 -K -d" command as per Ubuntu help page https://help.ubuntu.com/community/SynapticsTouchpad/ but it does not fix the issue with the said chechbox and hardware button. I guess it still needs to access shared memory using SHMconfig option in xorg.conf in which case it is the same bug that has been around for 3 years starting from Ubuntu 11.10 ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: xserver-xorg-input-synaptics 1.7.3-1ubuntu1 ProcVersionSignature: Ubuntu 3.13.0-6.23-generic 3.13.0 Uname: Linux 3.13.0-6-generic x86_64 NonfreeKernelModules: nvidia ApportVersion: 2.13.3-0ubuntu1 Architecture: amd64 CurrentDesktop: Unity Date: Fri Mar 21 10:10:18 2014 DistUpgraded: Fresh install DistroCodename: trusty DistroVariant: ubuntu EcryptfsInUse: Yes MachineType: ASUSTeK Computer Inc.
