Touchpad issues under Arch

Posted 09-25-2016 at 09:47 PM by drask

Here's an issue that I keep having ever since I switched to Arch. Most of my computers are Dell Latitude laptops, which use an AlpsPS/2 ALPS DualPoint TouchPad. After installing Arch Linux on them, I always end up with a strange situation where any time I put my finger on the pad, the mouse cursor jumps to that location within a small square about half the size of my screen, making it impossible to move the mouse out of that square.

So, to move the mouse to the upper left part of...

wireless lan on raspberry pi

Posted 12-29-2013 at 10:47 PM by drask

I just had to rebuild my raspberry pi again. It seems to keep eating its sd card for some reason. I decided to forgo the gui this time since it's a headless server. I just access it via ssh and vnc and I think I'm ready to drop vnc. Generally all I use X for is editing files in leafpad, and I can just as easily run pluma locally and connect over sshfs.

I have a pretty simple wireless setup - an open wireless network with no keys or certificates (I live on a farm, I'm not concerned...

Displaylink display

When I first bought my current workstation (currently running Wheezy) several years ago, I got a base station that featured two DVI ports and a VGA port. "Hot Dog" I thought, "I can plug three monitors into the back of this thing, one into the side, and with the laptop screen I can have up to 5 monitors on my workstation!" Imagine my disappointment when as soon as I plugged in the second DVI monitor, the display on the laptop screen disappeared. I was really looking forward to...

Gnome 2/MATE leave message

Posted 09-04-2013 at 10:18 AM by drask

I've been using the MATE screensaver instead of xscreensaver just because when you lock your screen someone can leave you a message. However, I was having a problem where if I actually try leaving myself a message, it never showed up. I got the answer for this from the following wiki page: https://wiki.archlinux.org/index.php...me-screensaver

Basically, you must install the "notification-daemon" package. Then if someone leaves you a...

WiringPi-Perl example

Posted 08-12-2013 at 09:11 PM by drask
Updated 08-16-2013 at 01:11 PM by drask

This is a Raspberry Pi project I did a few months ago and meant to post somewhere. There is a Perl interface to the WiringPi module. It's available from https://github.com/WiringPi/WiringPi-Perl. Unfortunately it doesn't come with any examples, but the WiringPi module comes with some nice examples. Unfortunately they are all written in C and it can take some trial and error to translate and I never found any translations of the examples online, or any WiringPi-Perl specific examples.
