raspberry pi openbox screen resolution

Sometimes a monitor won't report it's largest available screen resolution correctly. In such a case, you'll have to set it manually. My first hit on Google suggested some xrandr trickery which didn't work for me. Here's what did.

sudo raspi-config

Go to Advanced Options -> Resolution and choose yours. Both DMT and CEA modes worked on multiple devices, just make sure you got the right screen ratio and refresh rate.

Leafpad: lightweight GUI text editor for rox-filer on Openbox / Raspberry PI

I needed a lightweight file manager for an Openbox machine. rox-filer seemed like a decent option. But in order to look for and manage some config files, I needed the ability to quickly view their contents, so rox-filer alone wasn't enough, I needed a lightweight file editor too. Looking through the officially suggested options, I found leafpad. I ran most of those suggestions against apt-get install --no-install-recommends, and even with the no-recommends flag there were about 50MB of required dependencies. However, leafpad (as well as rox-filer itself) required no additional packages to be installed.

apt-get install --no-install-recommends -y rox-filer leafpad

Then go to $HOME/.config/rox.sourceforge.net/MIME-types/text and put the following inside:

#!/bin/sh
LEAFPAD="$(which leafpad)"
"${LEAFPAD}" "$@"

Then you can right click pretty much any file, then choose "File 'example'" and then "Open As Text".

raspberry raspbian debian dhcp dhcpcd wicd wifi not connected

Pretty much the same issue as desceibed here:

The network shows up in the wicd-client menu, and when I click connect, it gives me the usual messages: Doyle-WiFi: Disconnecting active connections... Doyle-WiFi: Putting interface up... Doyle-WiFi: Validating authentication... Doyle-WiFi: Obtaining IP address... Doyle-WiFi: Done connecting... But it doesn't actually connect to the network, and just goes back to the default "Not connected" message.

Source: Wicd looks like it's connecting just fine, but doesn't I'm using this on a raspbian with WICD GUI installed. What helped me was going to Wicd settings, then external programs and setting the preferred DHCP client to dhclient source
