I've joined the world of Trusty Tahr -- there were a couple bumps

[Tom_ZeCat]

I finally upgraded. As far as I can see, Trusty Tahr appears to be running fine. There were a couple bumps.

1. It uninstalled LibreOffice. (solved)
WTF? I thought that was its default Office suite. No biggie. I reinstalled it.
2. It uninstalled the dependency files needed to run Le Conjugueur, a French verb conjugation application that I use. Fortunately, I've been through wrestling with getting LC to run before. It's an older program last tested with Ubuntu 8.04. You have to install a 32-bit dependency file that Ubuntu has abandoned. If you need to run Le Conjugueur, you can find my explanation how at the following link. Skip to the end where you can find my letter to the developer in French and in English:

3. I plug a mouse in and use it, but I'm back to having problems with accidentally hitting the laptop's touchpad and messing up my cursor position. This is the one I still need to figure out. (still not solved)

Most laptops have a Function key combo to turn off the touchpad.

If not, try mapping keycode 201 to some key you don't use

You can turn off Touchpad in,
System Settings > Input Devices > Touchpad, ( and if I remember correctly you can set it up to disable touchpad when a mouse is pluged in)

In the touchpad setup there's an option called 'Palm Detection', it makes the thing less sensitive to.... your palm.
I hate using a touchpad, one reason I only buy laptops with a track point like the Thinkpads en Toshiba Tecra's so I typically disable the thing.
But since I found this palm option it doesn't bother me very much any more.
.

It's way better now.

Install kde-touchpad. It allows for setting the touchpad so that when a mouse is plugged in, the touchpad is disabled.
