742717 - [Desktop Build]B2G Desktop graphics problems on Ubuntu

Status: RESOLVED WONTFIX

(Firefox OS Graveyard :: General, defect)

Description

[Ben Francis [:benfrancis]]

Whenever I run a B2G desktop build on Ubuntu I get very choppy graphics, with parts of the UI disappearing (e.g. the homescreen icons disappear and the background shows through) or being replaced by black boxes. If I move the B2G window or move the UI elements on the screen they re-appear, but then disappear again after a second or so.

If I run B2G with the -jsconsole flag, the graphics problems apply to the JSConsole window as well.

This has been a problem for as long as I can remember and occurs for me on a MacBook, a MacBook Pro and an Intel i7 desktop machine running Ubuntu 11.10. Etienne has the same problem on his new Thinkpad running Ubuntu.

I'm not sure if this is a Gecko problem, a graphics library problem or a graphics driver problem on Ubuntu.

Sounds like an OpenGL/driver issue.

The default b2g prefs file forces on GL layers compositing.  When we first wrote the code, GL layers was forceably disabled on mobile, so we had to override that.

You're probably running tests on machines with blacklisted graphics cards.  All GPUs are blacklisted on X11 right now.

We should investigate removing the force-GL pref.

kaze mentioned that as a workaround you can add

user_pref("layers.acceleration.disabled", true);

to prefs.js in your profile.

I add user_pref("layers.acceleration.disabled", true);

to prefs.js in my gaia/profile 
still when you press home key. Icons disappeared.

This doesn't sound like the same bug weijia, what do you mean when you say icons disappear? Is it just app icon on the homescreen pages, or icons in the dock as well? are you able to provide a screenshot?

Yes, it doesn't sound like the same one.
Let me describe it a little bit.(Ubuntu 12.04 64 bits
1. download b2g latest(b2g-19.0a1.en-US.linux-i686.tar.bz2)
2. run b2g -profile $MYPROFILE/profile
  messages are 
/usr/lib/gtk-2.0/2.10.0/menuproxies/libappmenu.so: wrong ELF class: ELFCLASS64
