With all the noise about google switching away from XMPP, I was pretty concerned when Pidgin stopped connecting to Google Hangouts (aka gtalk or xmpp) with the following error:

"Server does not use any supported authentication method"

I wasted some time updating things hoping that would solve it before I finally figured out my problem: It wsn't google changing things at all; it was me. I'd changed the hostname of my (relatively new) laptop. But what I hadn't done was put the new hostname into /etc/hosts under 127.0.0.1. A quick edit later, and the newly christened laptop is back on the air.

I found the solution here, but I had to dig for it a bit so I'm puting up this post that shortcuts to the answer without the debugging, just in case anyone else runs into this one and needs help.

This is more a note to self than anything else, but who knows, maybe someone reading is having exactly the same problem as me?

The "new" laptop has an overly sensitive touchpad, in that it seemed to be clicking at times when I didn't want it to click. While quite a few people handle this by disabling the touchpad or disabling tap-to-click, I knew from experience with my last linux laptop that this is a solvable problem under linux at least.

There's a *lot* of ways to control mouse settings, but here's the one that worked for me. In short:


xinput list
to find my touchpad device, which turned out to be id=12

xinput list-props 12 |grep -i finger
to give me a list of relevant entries

xinput set-prop 12 "Synaptics Finger" 25, 32, 256

to set it to something that seems better behaved.
According to the link above: "By increasing the second parameter, you require more finger pressure for the trackpad to respond. The first parameter controls release pressure, the third is to detect a button press (I think)."

and that seemed to match up. In my case, I needed to up the second number. While I was in there, I tweaked the two-finger settings so it'd be easier to "right click" with two fingers.

Lest it's useful to me later, here's my current settings:
terri@djpwn3:~$ xinput list-props 12 |grep -i finger
Synaptics Finger (261): 25, 32, 256
Synaptics Two-Finger Pressure (268): 256
Synaptics Two-Finger Width (269): 1
Synaptics Two-Finger Scrolling (272): 1, 1
