Ubuntu Touchpad toggle tweak

by

I've been getting irritated with the touchpad on this new Dell Vostro 1400. I type for a while, and then my palm touches the touchpad, sending the pointer skimming into the line above, or clicking on buttons I don't want to click on. So, I looked around and figured out a solution. Over the past two years, I've had to update this post for every single new version of Ubuntu, which has been a pain, so look for the heading below which corresponds to your version of Ubuntu.

Ubuntu Hardy 8.04

First of all, you need to edit your /etc/xorg.conf file, for which you'll need root privileges – use sudo.You just need to add one line in the input device section, which is the one in bold below. (Intrepid 8.10, see below)

Section "InputDevice"
        Identifier      "Synaptics Touchpad"
        Driver          "synaptics"
        Option          "SendCoreEvents"        "true"
        Option          "Device"                "/dev/psaux"
        Option          "Protocol"              "auto-dev"
        Option          "HorizEdgeScroll"       "0"
        Option          "SHMConfig"
EndSection

Physician Heal Thyself: When WordPress Themes go Bad

by

Just had an irritating couple of hours when I discovered that my WordPress Theme was broken. The sidebar had slipped to underneath the main column, and the background of the main posting area had disappeared. I tried clearing my cache first of all. Then I tried looking at the site in different browsers. It was still broken in IE: although the symptoms were slightly different the sidebar was still misplaced.

OK, time to roll my sleeves up …

Getting Wireless to work on a Dell Vostro 1400

by

Having spent hours tinkering with getting Ubuntu's wireless to work on at least three previous Thinkpads, before I bought this Vostro I did some research around the internet. I found a bunch of happy Vostro 1400 Ubuntu 8.04 users, and the fact that Dell was releasing Ubuntu on some of its other machines. Good signs. However it seems that the hardware specs between Vostro 1400s vary depending on where and when they're manufactured, so I think that research might have been misleading.

Anyway, I've been trying to get wireless working on and off for the last 3 or 4 weeks, and I'm almost there, so I thought I'd share my experiences.

Audio Ping Feedback.

by

Step back a few years … I've often thought when I'm under a desk somewhere jiggling wires, is that some kind of audio feedback on ping would be useful: your server isn't responding, but when you re-seat the ethernet connector it comes back online; you have a messy, unlabeled switch to work through, so you unplug wires until the audio feedback stops, and you've located your machine. That kind of thing.

I've occasionally looked around the internet for such a tool and uncovered a couple of scripts and tools which don't quite work. I've even thought of writing my own script, but never quite got around to it.

Strange SmartBro URL hijacking

by

I'm at a loss to explain this unless SmartBro's DNS or proxy servers have been taken over. Here's the deal. I'm surfing normally, and then suddenly I try to go to a normal site (economist.com, yahoo.com, facebook.com, google. com, iptools.com etc) and instead of getting the correct page, I get a weird spammy advertising page, even though the URL in the Address bar looks correct.

The image to the right is an example. Click on the image to get a full sized view. I have more examples saved if anyone is interested.
