Backtrack 4 Installation StartX Error: AddScreen/ScreenInit Failed For Driver 0

Errors36 Comments

When installing Backtrack 4 on a Windows Virtual PC VM this afternoon I got an error when attempting to start the X server. After initially booting the DVD inside the virtual machine I set up for the Backtrack 4 installation I got the error starting X with the startx command. Resolving it was easy for me though I don’t know that it would always be as easy for others. Below I describe the error received when starting X and what I did to resolve the problem.

Canfield Imaging Systems Mirror Software: License Server Error – err: 81F4000F

ErrorsLeave a comment

A medical research company that is a client of mine asked if I would come by to install some software for them the other day. The software was supposed to be an addition to Canfield Imaging Systems VISIA software package called Mirror. The Mirror software was going to provide my client a way to manage the images created from within VISIA in a much more efficient and standard way. Currently they are able to export images either one at a time or as a bundle in a non standard file format which makes them fairly useless unless you are importing into another VISIA system. Anyhow during the software install I was unable to launch Mirror after the initial install because of a licensing server issue which I describe below along with how I was able to resolve the problem short term and what needs to happen long term to make the two software packages interact together.

I recently reinstalled CentOS on a server for a client and then proceeded to install their WordPress web site on the fresh install of CentOS Linux. After working through various minor issues the WP site was up and functioning without issue but after a week or so they contacted me to let me know that they could no longer view items in their FAQ system via the WordPress administration site. The FAQ system is a WordPress plugin called FAQ Builder and is a great little system for frequently asked questions. Below I describe the error received when attempting to access the FAQ Builder admin and what I did to resolve the issue.

Upgrade Redmine Rake Migrate Error: uninitialized constant ActionController::AbstractRequest

Errors2 Comments

I ran into an issue earlier where adding a sub project to an already existing Redmine project produced an error and after a little bit of troubleshooting determined that upgrading Redmine would resolve the issue. During the upgrade process I ran into some other issues including a specific migration error using rake that is noted below. The upgrade process involved upgrading Redmine 0.8.3 to Redmine 0.9.3.
