Window Manager missing after Upgrading Ubuntu

When I upgraded Ubuntu from 14.04 (Trusty Tahr) to 14.10 (Utopic Unicorn), the computer booted up fine after the restart. But after logging in, the Window Manager didn’t start up!

TL;DR … To fix this, delete the ~/.config/dconf/user file (or rename it), and then restart the computer.

When I logged in, the desktop was there with all the icons on it, but the top menu bar, and the side-bar were missing. When I opened up a window by clicking on a folder icon in the desktop, it would open, but it would be missing the title bar. So, basically seemed like the Window Manager was missing. After deleting the above mentioned file and restarting, it was all good again!

Apache Web Server – Require all granted

Just upgraded my web server to the current version of ubuntu and got caught out by a change in apache httpd. (Note to self: RTF-release-notes next time.)

It resulted with a 403 / Forbidden error, with the browser showing You don’t have permission to access / on this server, and a client denied by server configuration entry in the log.

The issue was the addition of mod_authz. It needs a new entry in the Directory section of your web site config:

Require all granted

It is equivalent to the old allow from all. Check the Apache mod_authz_core page for more details.

Luckyily this time it was a fairly easy fix, and mod_authz seems to have some fairly interesting features to explore. In any case, if your web sites stop working after an upgrade in your ubuntu server, this is probably the issue.

Setting up a subversion server

This article shows how to set up a subversion server that will allow local and remote access.

In this article we’ll set up a subversion server that will allow remote access. We will use Ubuntu, but the process isn’t that different if you are using a different distro.

First of all install the subversion package. In ubuntu thats:

sudo apt-get install subversion

Create a directory where you will store the subversion repositories. (we use /var/repos in this example.) Then, add a user for the svn (we’ll use the username svn), and give it ownership of the repos directory.

FIX: Firefox 3.6 not starting in Ubuntu 10.04 Alpha (Lucid Lynx)

I got Firefox 3.6 in a Lucid alpha update on 27 January. The problem is that it wouldn’t start. I tried it with a new profile, which made it work. So I ran firefox with the -safe-mode argument and disabled all add-ons. Then in firefox, I tried each add-on to figure out which one’s weren’t working, and left them disabled.

To do this, open up a console and run the following:

firefox -safe-mode

You’ll see the following dialog box:

Select the first checkbox (Disable all add-ons), and press the Make Changes and Restart button.

When Firefox starts up, go into the Tools->Add-ons menu. And try enabling each add-on and restarting firefox. If it starts, then the add-on is working. If it isn’t, run firefox in safe-mode and disable the last add-on you enabled.

In my case, Adblock Plus, Better Gmail 2, Better GReader, Firebug, FoxyProxy, Ghostery, HttpFox, NoScript, Nuke Anything Enhanced, and User Agent Switcher were working. DownThemAll, Greasemonkey, and Stylish were not.

Installing Ubuntu (Linux) on HP dv2899ea Artist Edition

The installation was simple, very similar to a Windows installation with no questions that should appear difficult to anyone who’s used a computer before. In under 30 minutes I had a workable system running Ubuntu, and that included Open Office and a working network/internet connection including WIFI!

After playing around with Vista for a couple of days on my new HP dv2899ea Artist Edition Notebook, I had decided it had to go. For starters it had a restore partition that had taken up 12GB and for some reason the actual supposedly fresh installation took up at least twice as much. But I made a set of system recovery discs on just in case if for some reason I decide to install it again. That took about a year and a half to create! (OK, may be it was a little closer to a couple of hours.) Continue reading “Installing Ubuntu (Linux) on HP dv2899ea Artist Edition”

Linux with better User Experience than Mac?

Infoworld has coverage of Ubuntu Linux Founder Mark Shuttleworth speaking Open Source Convention (OSCON), asking the audience Can we go right past Apple in the user experience we deliver, adding Certainly on the desktop experience we need to shoot beyond the Mac, but I think it’s equally relevant [in] the mobile space.
