Back in December, 2008, I posted Proper way to turn on SHMConfig in X Server 1.5 with input hotplugging, that was when HAL had not been deprecated. I checked my un-merging log, HAL was removed from my system in December, 2010, two years later of the post.
According to
If you don't have the file, then just create one in the same directory or one listed in
According to
man synaptics
, since X server 1.6, you don't need SHMConfig for changing settings on the fly via synclient
. However, the -m
touchpad activity monitoring option still requires SHMConfig, or you will get the same old error message:Can't access shared memory area. SHMConfig disabled?I have a plan for monitoring activity of touchpad, so I tried to turn it on again and the proper way is to edit
/usr/share/X11/xorg.conf.d/50-synaptics.conf
:Section "InputClass"The lines in bold text were what I added to it, the rest were the original content. I found out
Identifier "touchpad catchall"
Driver "synaptics"
MatchDevicePath "/dev/input/event*"
MatchIsTouchpad "on"
Option "SHMConfig" "on"
EndSection
/dev/input/event*
is crucial to get SHMConfig turned on. Without it, I still got the same error message saying SHMConfig disabled. I don't know if it also affects other options, but you don't actually need to put touchpad options here, you can change in your ~/.xinitrc
or write a startup script.If you don't have the file, then just create one in the same directory or one listed in
man xorg.conf
, X server looks into many different directories for configuration files.
