From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040115 Description of problem: After a clean install of FC2 test 1, tapping on the laptop's touchpad does not register a mouse click. Using the actual mouse buttons works fine for all six buttons; it's just tapping the touchpad that doesn't work. This did work in FC1 release. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Boot into KDE, Gnome, or failsafe 2. Tap mousepad. 3. Click mouse button. Actual Results: No response when tapping touch pad; click registered when using mouse button. Expected Results: click registered using either the touch pad or mouse button. Additional info: The laptop is a VPR Matrix 175B4. The mouse is configured as a generic ps/2 mouse with 3-button emulation (as it was in FC1); I've also tried the Alps and Wheel Mouse configurations. This also occurs whether or not gpm is running.
The mouse driver and other input drivers in XFree86 have not changed between Fedora Core 1 and current. I suspect that any difference in behaviour is caused by kernel changes from 2.4.x to 2.6.x, however I do not have this hardware and can not test or try to reproduce this personally. I'm carbon copying some kernel people who may be able to help determine if this is a kernel problem or XFree86 problem.
I have FC1 with both kernel-2.4.22-1.2149.nptl and kernel-2.6.1-1.65 on a Compaq Presario 2100 laptop. 2.4 kernel handles touchpad with support for tap (acts as click) and scroll section on right side (acts as scroll wheel). The 2.6 kernel handles touchpad for mouse movement, but no response to tap, and scroll area causes mouse vertical movement instead of scrolling. This is definitely a kernel problem. Dmesg excerpt: Synaptics Touchpad, model: 1 Firmware: 5.9 Sensor: 35 new absolute packet format Touchpad has extended capability bits -> multifinger detection -> palm detection input: SynPS/2 Synaptics TouchPad on isa0060/serio1
Disabling synaptics support fixed this for me. http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=112473
