No easy way to switch from two-finger scrolling to edge scrolling for an unsupportive touchpad
Last modified: 2013-09-05 10:50:29 EDT
Description of problem:
On a ThinkPad T500, the touchpad supports edge scrolling, but apparently not two-finger scrolling. After upgrading to Fedora 19, the default dconf setting in /org/gnome/settings-daemon/peripherals/touchpad/scroll-method disables edge scrolling that used to work, but does not make two-finger scrolling work. Switching the value to edge scrolling makes edge scrolling work as expected. In GNOME settings for the touchpad, the "two-finger scrolling" checkbox reflects the dconf setting, but is disabled for input, and there is no way to enable edge scrolling.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Upgraded Fedora 18 -> 19 on a Lenovo Thinkpad T500.
2. In a GTK+ application that features a scroll bar, try edge scrolling or two-finger scrolling.
3. In GNOME settings for mouse and touchpad, check the setting for two-finger scrolling.
Neither scrolling gesture works. The control panel setting is enabled, but grayed.
Either two-finger scrolling should work, or it should be disabled by default (as a result of input device autodetection?). Edge scrolling should be available as an option, or work out of the box.
The unsolicited configuration change from edge scrolling to two-finger scrolling during upgrade is a bug per se.
Setting can be changed manually from terminal:
gsettings set org.gnome.settings-daemon.peripherals.touchpad scroll-method 'edge-scrolling'
After this, scroll setting is changed, and setting is changed in settings panel, but checkbox is still disabled for input.
