https://bugzilla.novell.com/show_bug.cgi?id=282997 Summary: Kernel bug+oops partly disables touchpad Product: openSUSE 10.2 Version: Final Platform: i586 OS/Version: openSUSE 10.2 Status: NEW Severity: Normal Priority: P5 - None Component: Kernel AssignedTo: kernel-maintainers@forge.provo.novell.com ReportedBy: ruedas@dtm.ciw.edu QAContact: qa@suse.de Hi, my laptop (Amilo Pi 1536 w/ Centrino Duo) has a touchpad which has two areas, the large main one for "tapping" input and a narrow strip on one side for scrolling. Sometimes the touchpad would not respond to any but the most basic, single-finger "tapping" input, i.e. scrolling, two- and three-finger actions etc are suddenly disabled, which severely reduces the usefulness of the touchpad. The only way to reactivate this seems to be to log out so that X is restarted. The relevant output from /var/log/messages is given below; possibly the graphics card module (fglrx, for an ATI Radeon Mobility X1400) is involved, but I don't know if it's crucial for the bug to occur. I seem to recall that I experienced this problem with SUSE 10.1 as well on one occasion. The first two lines of this messages output occur quite frequently, but don't seem to affect performance and are apparently unrelated or only loose connected to this problem.
