           Summary: synaptiks-0.7 crashed after suspend with ALPS touchpad
           Product: kde
           Version: unspecified
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: sven.eden at gmx.de


Application: python2 (0.7.0)
KDE Platform Version: 4.7.1 (4.7.1) (Compiled from sources)
Qt Version: 4.7.4
Operating System: Linux 3.0.4-gentoo x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:
This crash happens every first time the system wakes up from suspend. If
synaptiks is then restarted, I can suspend the laptop and wake it up without a
problem. It only happens after the first suspend after a reboot of the machine

- Custom settings of the application:
I am using a 3.0.4 kernel with gentoo patches and the ALPS-enabling patch from
here: http://people.canonical.com/~sforshee/alps-touchpad/ (version 0.7)
discussed here: https://bugs.gentoo.org/show_bug.cgi?id=318567 making the
system to accept the ALPS touchpad as if it were a synaptics tp.

Although this is a custom patch not accepted upstream (yet), it might be a
chance for the synaptiks author to share their experience with the patch author
to eventually make ALPS touchpads, which gain on relevance these days, work as
well on linux as synaptics touchpads do. Therefore I decided to file this
report.

The crash can be reproduced every time.
