We've been trying to keep desktop on life support while it uses out-of-process content, omtc, and GPU compositing on some platforms where that's not officially supported. Time to pull the plug.

Additional notes - platform folks doing work that depends on nice things should know how to turn these things back on as needed - I ran into the "Mozilla black screen of death" when testing this patch with bug 819716. Probably an existing race condition that we happen to hit.

I applied to the patch, works great for me, first time I've seen anything but a white screen in over a month.

This now blocks a blocker.

Chris, late last night I did a mozilla-beta build (rev 3fcae8234ba9 + this patch) and b2g-desktop still launches into "mozilla" and then a blank screen, on Ubuntu-12.04 in VMWare 9.

That was with gaia revision c2c9bc9875e3a85b860219f752df8894277fc938.

Suspicious-looking things here JavaScript error: app://system.gaiamobile.org/js/bluetooth.js, line 36: bluetooth is undefined JavaScript error: app://system.gaiamobile.org/js/wifi.js, line 52: wifiManager is undefined This might be a recent regression that's breaking the system app on startup. XXX FIXME : Got a mozContentEvent: system-message-listener-ready ************************************************************ * Call to xpconnect wrapped JSObject produced this error: * [Exception...

I have a working local build. In it, I see the first set of errors but not the second. So that seems likely to be the problem.

bluetooth might be undefined if you're not building with --enable-b2g-bt.

(In reply to Kyle Machulis [:kmachulis] [:qdot] from comment #12) > bluetooth might be undefined if you're not building with --enable-b2g-bt. I think one cannot build b2g-desktop with --enable-b2g-bt: /home/hacker/b2g-desktop/src/dom/bluetooth/BluetoothUnixSocketConnector.cpp:30:33: fatal error: bluetooth/bluetooth.h: No such file or directory

You just need the libbluetooth-dev package. I'll try to get that added to the wiki.

Comment on attachment 690139 [details] [diff] [review] Take away the nice things from desktop b2g builds [Approval Request Comment] Bug caused by (feature/regressing bug #): multiple bugs User impact if declined: Many users won't be able to run the B2G desktop builds that most closely resemble the first Firefox OS release, including localizers localizing B2G and app developers developing apps for it. Testing completed: Various folks have tested this patch (and similar ones) and reported success running B2G Desktop with it. Risk to taking this patch (and alternatives if risky): This only affects desktop builds, which are already pretty broken (hence the patch), so it isn't very risky. String or UUID changes made by this patch: None.
