Compiz Gets Thumbs-Up for Gutsy Gibbon 303

Posted by Zonk
from the cheeky-monkey dept.
Da Chronic writes "After a vigorous debate at the last Ubuntu Technical Board meeting, the board decided to ship Ubuntu 7.10 with Compiz enabled by default. The decision was made despite the fact that Compiz still has some significant issues relating to drivers and Xorg. 'For instance, there are some problems — like accelerated video playback issues with Intel drivers — that can only be resolved by using the EXA accelerated rendering framework which is still not ready yet. When asked why Intel isn't addressing the driver issue, technical board member Mathew Garrett explained that "Intel are working on the basis that composited desktops won't be ready for rolling out until EXA is stable enough anyway, so it's not a concern [for them].' In the end, all but one member voted to include Compiz in Gutsy."

    Here's your wikipedia. Thanks, submitter.

    Compiz is one of the first compositing window managers for the X Window System that uses 3D graphics hardware to create fast compositing desktop effects for window management.

      Look at how long the submission is. Why would you make it even longer by including a definition of what a relatively popular software component is? You might as well include definition for Ubuntu, Gutsy, and Xorg while you're at it.

      Keep up with the times or use Google/Wikipedia when you don't know what something is (like you just did).

      Why would you want to compost your desktop? Ohhhh, composite! My mistake. Looks interesting, but there have been many interesting technologies for X that have died. You seen many window managers lately that let you link and scroll between virtual windows as a single gigantic desktop? Desktops-in-desktops also seem to be curiously absent these days. Not sure I've seen many recent 3D projects using PHIGS, either. OpenGL is great, but nothing is great for everything, and PHIGS was a standard extension for X11.

      I've been running Compiz in its various forms (compiz-quinnstorm, beryl, now compiz-fusion) on Gentoo since around March of 2006, and while I can see where you're coming from I have found some of its features actually useful. The ones I particularly like are: the expose clone (google 'expose mac to see what I'm referring to), the live alt-tabs (you see what's running in the alt-tab windows), it allows for extensive key bindings (I know you can use other programs like xbindkeys, but it at least beats Metacity's binding capability), and transparency (compiz isn't required to do this, but it makes it a lot easier than other WM's -- basically it's designed with that in mind).

      I originally thought the same thing with Beryl (the breakoff from Compiz, which is now remerging into compiz-fusion), and thought, "hey it looks nice, but that's about it". I left it installed on my machine as it was pretty stable and didn't see a need to remove it. After a while I started rearranging and managing my desktop-- all development work in one window, terminal windows in another, email/web browser in another, and the last for visualization apps (imageJ, matlab, etc.). It wasn't until I had all four desktops being active used that I realized how much easier it was to multitask with a more sophisticated windows manager. I could actively switch between desktops fast, drag and drop items from one desktop to the other, separate global and local task switchers-- all much faster and with less downtime than before. Now I find it rather limiting to use a linux box that doesn't have it installed.

      The only thing really holding it back is the stability issues (my desktop has no problems, but my laptop crashes at least once a day with it enabled). It doesn't hurt to install it and give it a try-- if you don't find it useful at first but it runs stable, then leave it installed-- you might come back and find it useful someday.

Then I hope it is also easy to enable/disable simple features that suits my liking, with and option to save and switch between different profiles.

    But I still wonder if what I dream of is simply a fairytale, or whether this can be expected?

    If there has to be "vigorous debate" about something like this, then it is not ready to be turned on by default, plain and simple. The article says the developers don't know how stable Compiz-Fusion is, because they don't have data, etc. But they have doubts, which is all that matters. It would be fine to go forward with turning it on by default if all the devs ran it and none experienced any problems. Instead, there are known problems (such as this Intel problem) and some of the devs acknowledge that the thing can crash once a DAY, which is consistent with other experiences I have read as well.

    New users (Ubuntu's target, I believe) will try Ubuntu, see this thing crashing all the time, and think "why did my geek friend tell me this Linux is more stable than Windows? My XP doesn't crash once a day."

    One dev said "if we don't get it out there at some point it'll never get good enough." I don't see how foisting it on new users will help get it into shape. Are the Compiz-Fusion devs not busy enough already? There are apparently already KNOWN ISSUES that aren't being fixed, so how is turning it on by default going to improve anything? It surely will not generate better bug reports--new users will not know Compiz-Fusion is the problem; how are they going to bugreport it?

    I hope Compiz-Fusion shapes up soon or that Ubuntu reverses itself; if not, this release will be a slide backward for many users--it will resemble Vista: a release with lots of paint, but with no improvements under the surface.

      If we don't get it out it'll never be good enough
      The basic idea here is that by shipping it with bugs, you'll motivate a few people who wouldn't have otherwise used it to investigate. In some cases, this is true. But realistically, we're not sitting on a pile of unused openGL / video driver development talent. Any such slack was picked up by Intel and put to work on what they felt pressing, and as such is not available to meet Canonical's unpaid requests.

      We don't even know how bad it is
      There are 150 open bugs against compiz, and only 3 labelled critical. But we really don't know how perception of compiz affects bug reporting. We know not all bugs found are reported by it's finder. It's possible that compiz is known to be unstable and rather than report, people just disable and get on with life, assuming compiz stability will continue to be a back burner issue. Dropping compiz into gutsy by default would likely expose more users to bugs.
      This exposure is theoretically what testing is for, but for various reasons, hasn't come to fruition. One is that upgrades don't enable compiz. Another is that people come to testing not for Ubuntu's sake but for theirs. They're interested in significant new software, or preserving some hardware compatibility.

      Or it's simply possible that that's all the bugs there are. But I doubt that.

      However
      Ubuntu does have a significant support structure in place capable of dealing with all but the most egreious failures (think broken X server pushed out). Launchpad does a good job of searching for duplicate bug reports to bring people together, and test workarounds / patches. It's also got a way to attach to upstream bugs to follow on with. This is good because compiz's bugzilla is a nightmare.
  • Is it fair to assume it will be turned of by default on Xubuntu? Doesn't make much sense to enable shiny desktop effects on a distro designed to be compatible with older hardware...

    Also, while many people seem sceptical about stability I guess we will just have to wait and see how well they handle the cases where 3D acceleration is a problem. I.e, will it be careful about enabling it if a proprietary driver is needed? How well will the crash handler manage to respond if it doesn't work etc... Under the assu
  • While people complain about needless flashy graphics what this is really intended for is a framework for putting the GPU to work on tasked like image processing. See how Apple's "Core Image" works.
