The primary reason for this of course is, that without having set the "SHMConfig" Option to "on" in the touchpad section in xorg.conf, it is impossible to dynamically change any touchpad settings. The "SHMConfig" by default is not set in Ubuntu nor in any other distro AFAIK.
I believe it was a comment from Xorg that stated, that this is due to security reasons. However, I do not fully understand, why it is no security threat to dynamically change mouse settings but it is a threat to change touchpad settings. It is indispensable to allow users to change their touchpad settings dynamically. It is also indispensable to include functionality in Ubuntu to temporarily disable touchpad tapping when typing on the keyboard. As non of this can be accomplished without the SHMConfig option, I suggest to get upstream involved to discuss the quoted security issues. -- Adjusting mouse speed has no effect on Touchpad https://bugs.launchpad.net/bugs/75819 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
