From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040312 Description of problem: Hello, I reported this issue on X, but I'm not sure what's guilty for this. When I use the touchpad of my laptop as a mouse, the mouse often displays an erratic behaviour: - The mouse jumps to a completely different position on the screen - Some windows are brought to the front, and some applications (like a web browser) behave as if one of their action buttons had been clicked. This is a pain as the applications don't do want you're trying to do with them, in particular before you're done entering input data! This can happen up to several times per minute. This can also stay several minutes without happening. A work-around that works in 100% of the time for me in to plug-in my USB weel mouse and stop using the touch pad. Then, there is no longer any issue with the mouse cursor and behaviour. Note that this didn't happen in FC1. However, this happens since FC1 T1 (was also there in FC2 T2), but I didn't take time to report it. I consider this as a severe issue as it makes it very uncomfortable to use my laptop without an external mouse, which typically is not convenient at all when travelling. If some of you are facing this too, please share your experience too on this bugzilla ticket! Cheers, Michael. Version-Release number of selected component (if applicable): xorg-x11-6.7.0-0.5 How reproducible: Sometimes Steps to Reproduce: 1. Take a laptop 2. Unplug external mice 3. Use the touchpad instead of the mouse Additional info: Here's how my mouse is declared in /etc/X11/XF86Config: Section "InputDevice" Identifier "Mouse0" Driver "mouse" Option "Protocol" "IMPS/2" Option "Device" "/dev/input/mice" Option "ZAxisMapping" "4 5" Option "Emulate3Buttons" "yes" EndSection My touchpad is reported as a "SynPS/2 Synaptics Touchpad" by the hardware browser.
I also have this problem. Another issue that I noticed that may be related to this is the inability to click-drag/tap-click by tapping your finger on the touchpad itself. I find having to click and hold the mouse button down to drag windows around/select text, etc (making it a 2 handed job) very uncomfortable. My hardware is the same. XF86Config, the same. I'm using Test 3 updated to the most recent packages as of 2:30AM MST
Same problem, reporting to get on the CC list. Erratic mouse movement, the mouse wheel section of the pad doesn't function, and tapping the pad does not produce a mouse click. It looks like the symantic mouse pad isn't being recognized correctly. It worked nicely in FC1. This is an HP Pavilion ze5300 laptop. I did an upgrade from FC1 to FC2 test 3.
Same erratic motion, and same inability to tap-click. Hardware: Advent 7011 Laptop. I did experience the erratic motion in FC1, and am currently experiencing something similar in FC2 test3 although I cannot be certain that it is the same problem. Mouse appeared to erratically jump to the left top and bottom of the screen. I to had "IMPS/2" in XF86Config, and xorg.conf. After changing to "PS/2" it seems ok, but for how long?
This still happens in FC2 final. Hope a fix can be found soon... Cheers, Michael.
