Ubuntu 7.04 Alpha 5 - Problems with Compiz Fixed

Wouldn't you know it. Less than 24 hours after complaining about Compiz problems, I get a very nice comment giving me a very simple solution.

iGama said:
just add this 2 lines in xorg.conf , section Device :

Option "XAANoOffscreenPixmaps"
Option "AddARGBGLXVisuals" "true"

Restart your X , and problem with Compiz/Beryl fixed :)
I did, and he's right, as you'll see below. Not to bite the hand that feeds me, but I hope this fix is the 'correct' fix, and that it's included in any future releases. It's so simple (at least for ATI cards like mine, a 9600).

Thanks, iGama!

The first screen capture shows three gterms and the system monitor. What's really nice is that the gterms have true transparency. If you enable gterm transparency without Compiz, the gterm simply maps the desktop image into its background. But now I can see everything under the gterm. More than just pretty eye candy, I can keep track of other dynamically updating applications (such as top, or something like Gmail in Firefox). Another nice feature is the three dimensional shadowing that also helps to distinguish windows on the desktop. It really adds a level of polish to the whole affair.

This is an example of Expose-like behavior, which I definitely like. Move the mouse to the upper right corner, and the overlapping windows resize and reorganize into smaller versions of themselves, making for easier selection. Again, very nicely done.


  1. Just happy I could help, i have a ATI 9200, so also add that problem in the beggining.

    I've made a post on my blog about Feisty also, some time ago, maybe you would like to read :

    I'm starting to work on an article for a online portuguese magazine presenting the new Ubuntu 7.04. When its ready, it will be in english available for all also.

    Also, another sugestion, I've noticed you have some articles about Ubuntu, why not join the Ubuntu User Planet?

    See ya ;)

  2. PS, just noticed another post of yours talking about the control panel.

    To activate the control panel again, open a Terminal, write :

    $ alacarte

    Go to System and activate it :D

    You always have the choice in Ubuntu.

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…

Be Careful of Capital One Mailings

Capitol One ("What's in your wallet?") sent me a bit of deceptive snail mail today. I felt sure it was a credit card offer, and sure enough, it was. I open all credit card offers and shred them before putting them in the trash. Normally I just scan the front to make sure I don't miss anything; the Capital One offer made me stop for a moment and strike a bit of fear into my heart.

The letter's opening sentence read:
Our records as of December 30, 2009 indicate your Capital One Platinum MasterCard offer is currently valid and active.Not paying close attention during the first reading, I quickly developed this irrational worry that I was actually on the hook for something important, but I wasn't quite sure what. The letter listed "three ways to reply" at the bottom; via phone, the internet, and regular snail mail. I elected to call.

Once I reached the automated phone response system, the first entry offered was '1', to "activate my Capital …

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…
