Ubuntu 7.04 Alpha 5 - More Problems, Solutions with Compiz

After getting Compiz to finally work on this modest system, I started to use applications on Ubuntu. The first application I opened was NetBeans 6 Milestone 7. NetBeans presented the first post-success problem I ran into. There is a problem with Java rendering Swing under Xgl/Compiz (bug 6429775). I had already installed Java 6 build 105 via Add/Remove, and was happily using it. However, when Compiz is active, Swing-based Java applications have the same problem with rendering window contents as I noted in my earlier post about Compiz problems in general. The solution is to download and install Java 6 Update 1.

I downloaded the pre-release version of 6U1 from the Java 6 Developer site and installed it in a different location from the stock Java 6 RPM location. On my machine 6U1 is installed under /opt2/java. I then set up JAVA_HOME and modified PATH to point to 6U1 first instead of the stock Java installation. Finally, I modified etc/netbeans.conf (under the NetBeans installation root) and changed netbeans_jdkhome to point to /opt2/java, and restarted NetBeans. The results are as shown below.

And here's the biggest surprise (to me). It not only rendered, but this version of Java and Swing render Gnome theme controls by default. All I had to do was install this version of Java, and that capability was enabled automatically. Right now, Java and Java-based applications are behaving like first-class Gnome citizens. The only other OS where this works as well for me is Java 6 b105 and Windows XP.

Other Issues

I complained about the wobble, and wished I could turn it off. Well, if I'd just looked at the Desktop Effects applet for more than a second I'd have seen the "Windows Wobble when Moved" check box. I unchecked it, and the windows don't wobble. Doh!

Resizing windows is very bad. Grabbing any side or corner and dragging results in slow, choppy, window resizing.

Work spaces on a cube doesn't work. It works fine with Compiz on SLED 10 (and openSuse 10.1 and 10.2). Instead of flipping, the contents of one screen fade out, then the next screen selected fades in. It wouldn't be so bad if it weren't so slow.

Good Things to Consider

This is, after all (repeat after me) an Alpha release. It works very well overall for an alpha release. What is more telling is that it's working on a system that Vista would only sneer at if it had lips to sneer with. Making user's existing systems instantly second class with an OS upgrade is Not Cool. Especially when small- and medium-sized fortunes were already spent on major processors and video cards.

This system was purchased five years ago, and upgraded two years ago with trailing edge motherboard, processor, and video card. Using this hardware I've been able to enjoy the benefits of video acceleration (such as it may be) with out-of-the-box video drivers and software provided by Ubuntu.
Based on my personal experiences both Ubuntu 7.04 and openSuse 10.X represent two excellent alternatives, especially for existing pre-Vista systems.

You should never say never, but I will not purchase Vista for my own use. I will use it only because it was pre-installed on a job-related system. For what I need for the foreseeable future, it will be Linux or Mac OS X.
I'm curious to see if many will react to Microsoft's deep reach into your wallet and freedoms the way I have by moving with all due haste to test alternatives such as Linux.

A Decade Long Religious Con Job

I rarely write inflammatory (what some might call trolling) titles to a post, but this building you see before you deserves it. I've been seeing this building next to I-4 just east of Altamonte/436 and Crane's Roost for nearly 12 years, and never knew who owned it. Today on a trip up to Lake Mary with my wife I saw it yet again. That's when I told her I wanted to stop by on the way back and poke around the property, and photograph any parts of it if I could.

What I discovered was this still unfinished eighteen story (I counted) white elephant, overgrown with weeds and yet still under slow-motion construction. It looks impressive with its exterior glass curtain walls, but that impression is quickly lost when you see the unfinished lower stories and look inside to the unfinished interior spaces.

A quick check via Google leads to an article written in 2010 by the Orlando Sentinel about the Majesty Tower. Based on what I read in the article it's owned by SuperChannel 55 WA…

first night for the gingersnaps

The first night has passed and the two have managed to survive, in spite of what their tiny hearts might have thought when first arriving. Greebo, the larger of the two, has been in hiding the entire time so far. Ponder has spent the time zipping in and out of hiding spots, checking things out, and learning just how comfortable pillows are for resting your head.

During the night I felt the tiny body of Ponder hitting the bed as he leaped up on the side, and then climbed to the top to run around on top of me. At least once he play-attacked my fingers. He might be small but his claws are still quite sharp.

When I got up in the morning the bowl of cat kitten food was fairly well depleted. It's been refilled and fresh water put in the big dish on the floor. I'm assuming that both Greebo and Ponder are feeding and drinking. I have seen Greebo under the furniture peeking out at me when I went looking for him. I'm leaving him alone while he continues to adjust.

So far the guys h…

cat-in-a-box channels greta garbo

So I'm sitting at my computer, when I start to notice a racket in back. I ignore it for a while until I hear a load "thump!", as if something had been dropped on the floor, followed by a lot of loud rattling. I turn around and see Lucy in the box just having a grand old time, rolling around and rattling that box a good one. I grab the GX1 and snap a few shots before she notices me and the camera, then leaps out and back into her chair (which used to be my chair before she decided it was her chair).

Just like caring for Katie my black Lab taught me about dogs, caring for Lucy is teaching me about cats. She finds me fascinating, as I do her. And she expresses great affection and love toward me without coaxing. I try to return the affection and love, but she is a cat, and she takes a bat at me on occasion, although I think that's just her being playful. She always has her claws in when she does that.

She sits next to me during the evening in her chair while I sit in mi…
