Description Ahmed Shams 2011-09-28 17:01:11 UTC
On behalf of Glen Ditchfield(Bug Reporter):

Installing on a Dell Latitude D600, with a trackpad. The installer sometimes does not detect button1-up events on GUI buttons right away. When I press and release button1, the GUI button stays in its depressed visual state until I touch the trackpad again. If keep a finger on the trackpad and press and release button1, the GUI stay depressed until I move the cursor. (I do not have to move the cursor off the GUI button -- a tiny movement within the borders of the button is enough.)

This happened frequently on the first few installer screens, but buttons behaved normally on later screens.

In retrospect, this happened on earlier ISO releases as well. I thought I was imagining things...

On behalf of Glen Ditchfield(Original Bug Reporter).
Comment 1 Peter Hutterer 2012-03-25 19:22:38 UTC
is this still an issue and if so, can you reproduce it after the install? can you check with evtest if the button event is actually sent by the device or if this is buggy hardware?

The original Launchpad bug report is at https://bugs.launchpad.net/xserver-xorg-input-synaptics/+bug/463067. It contains an evtest run in comment 37, and also xev output in comment showing a long interval between ButtonPress and ButtonRelease events. 

The bug was present in installed Lucid and Maverick releases, but went away in Oneiric.
Comment 3 Peter Hutterer 2012-04-16 18:48:31 UTC
Thanks. Closing as WORKSFORME given that it works now in Oneiric.
