Beryl/AIGLX white cube issue

Filed under: Blog — krkhan @ 8:41 pm

Anyone who has ever tried to run Beryl using AIGLX must’ve heard about the infamous white cube issue. While facing this problem, the screen goes totally white and while you can rotate the cube, you can’t do pretty much anything else. As I had also spent about a week trying various methods to solve the problem, I thought to publish on my blog the combination that did work on my Intel G965 motherboard.

Apparently, the whole thing is messed up because of the opcode changes in glproto-1.4.8 and although I don’t have any idea why, downgrading glproto and recompiling Mesa and X.Org did not solve the problem for me. Nevertheless, the following setup worked like a charm:

Compiling these components might require you to install other ones (such as inputproto, damageproto etc.), but this page is not meant to be a HOWTO. I’m just confirming that the above mentioned things work for me on my Intel graphics card. There is even a new patch created for xorg-server but I haven’t tried it out myself yet (I’m away form my PC for at least another week). If anyone else can confirm some other combination to be working, I’ll be glad to list it here. Just leave a comment using the form below.

Comparison: Windows Vista vs. Linux

Filed under: Blog — krkhan @ 9:02 pm

It’s finally here, and everyone is talking about it. Microsoft’s new operating system promises a revolution in computing, and a safer experience for its users. But, anyone who keeps himself in touch with Linux news knows that our beloved operating system kicks Vista in the pants in every technical aspect worth considering. Honestly speaking, that won’t change much as the fan-boys will blatantly remain fan-boys, no matter what you throw at them and how rational your reasoning is. Still, I thought of comparing the the current states of Linux and Vista desktops so that I’d link any future Vista fan that I encounter directly to this post.

Let’s start …

Security

In October 2001, Microsoft launched the latest version, dubbed as XP, of their flagship product Windows. The company claimed that the new version was its “most secure operating system ever made”. While installing the OS, the screens constantly kept reiterating words such as “security, usability and dependability”. Given that most of the Microsoft’s users are people who know as much about security as I do about Organic Chemistry, the marketing tactic indeed proved quite successful. However, it wasn’t long before crackers, virus writers and trojan makers started targeting XP, and the most secure OS of Microsoft was collectively devastated. To remedy the situation, Microsoft came up with Service Pack 2. This time using taglines such as “latest security updates and innovations from Microsoft”. These “new proactive protection features” were nothing more than a collection of fixed bugs, default firewall and a “Security Center” that constantly bugged you about installing an Anti-Virus on your PC. The Anti-Viruses had to run in background to perform their routine tasks, and as a consequence, you were left with lesser resources to do your work. It was almost impossible to edit multiple spreadsheets efficiently in Office while having Norton’s AV “shield” your PC from known threats.

The common misconception about Windows’ inherent security troubles was that Windows is less secure only because it’s more targeted by malicious crackers. It was useless telling people who believed it that Windows only dominates the desktop side of computing; and that more damage could’ve been achieved by crackers if they targeted *nix operating systems (which dominated and still dominate the server side of computing) and they had been flawed in security like Windows. The actual reasons for Windows being horse crap in terms of security were quite different. The initial versions of Windows were never created as a network operating system, and the situation became ugly only when the later versions were used as one. There was no proper privilege system in Windows, and even XP’s firewall filtered only inbound traffic. Ironically, with Vista, Microsoft is implementing long time security practices that *nix operating systems have always had, and flagging their operating system (once again) as “more secure operating system than any other”. Things like file system encryption, firewall and a user privilege system were present in real networking operating systems like FreeBSD and Linux for a long time before Microsoft even considered adding them to Windows. In fact, it still astonishes many seasoned *nix users that millions of Windows PCs used to connect to the internet without a proper firewall and a user privilege system. The funniest thing about the whole phenomenon is that Microsoft is tagging the whole thing is “innovation”. Leaving that aside, even if we consider the current states of security features for Vista and a Linux operating system, Vista still lags behind due to technologies like SELinux, iptables and the platform portable nature of Linux itself.

Look and feel

Another feature of Vista which admirers love to brag about is the Aero interface, while the misconception (which wasn’t a misconception really, quite a few years back) about Linux is that the GUIs of its desktop environments aren’t as user friendly and aesthetically pleasing as Macintosh or Windows. Recent developments such as Xgl, AIGLX, Beryl and Cairo have provided Linux the most impressive GUIs of any operating system, and I’m not just issuing hollow statements like Microsoft here either. Consider having multiple “virtual” desktops on a cube which you can rotate and view in real-time. Right now, it’s only possible with a hardware accelerated X server like Xgl or AIGLX.

And let’s not forget that you have something in Linux which Windows will never be able to offer: the choice of desktop environments. So if you don’t want to have all those effects, or even if you have a computer with only 64 MB of RAM, you can always run a minimalist window manager e.g. Fluxbox.

Conclusion

There are also other “innovations” of Vista such as desktop widgets and search tools which have been present in Linux for years in form of SuperKaramba and Beagle. Nevertheless, as I’ve said before, the “ignorant fan-boy syndrome” has no cure, and there will still be people who’ll find it very satisfying to pay money for things like operating system, office software and email management software. Even when a Linux distribution offers gigabytes of those utilities for free (in terms of both beer and speech).
