touchpad gone screwy since update to 12.2

English Install/Boot/Login
#1

Since the dup to 12.2 my touchpad has gone weird, and I can’t change the settings. It’s a thinkpad t420.
It no longer obeys any settings with regard to scrolling. It always displays the same behaviour no matter what changes I make via the KDE systemsettings module or synclient. It always acts like this: The left edge acts as a single-finger ‘reverse scroll’ (ie drag up with one finger on the left edge and applicattion scrolls down). Right edge does the opposite (ie normal one-finger scroll). Middle of the pad acts as I would like it (double finger scroll).

Any help gratefully accepted.

How is this a Tumbleweed issue?

confused,

Because I’m running tumbleweed. I’m referring to the dup which dumped everything from the tumbleweed repo and replaced it with the 12.2 packages.

At this point in time, no, you aren’t “running” tumbleweed as there are
no packages in the tumbleweed repo.

This is a “stock” 12.2 release at the moment, so I suggest you ask on the
normal forum for that release as to how to get this resolved, or file a
bug at bugzilla.novell.com.

good luck,

OK thanks, I was unaware of the narrow scope of this forum; I will raise it elsewhere. Or I might leave it, as I suspect it’s something that will disappear when the 3.5 kernel is back in TW repo anyway.
Cheers

Just to close this off - it was an option called Circular Scrolling, which despite being turned off in systemsettings was still set to ‘1’ when checked with synclient. Turning it off with ‘synclient CircularScrolling=0’ fixed it.
