[Bug 1758009] Re: Unity not starting: compiz-config crashes on login
I think I found the root cause for the compiz-config-profile-setter segfault. The call "ccsFreeContext(context);" in line 218 in compiz_config_profile_setter.c frees the context object while background event processing still uses the object, which then leads to the segfault. It seems the set_compiz_profile() call returns while a value-changed callback gets called in the background, which then calls ccsObjectGetInterface_() on the context object, but by then the context object already got destroyed. I think the best way so solve this, would be to wait for the event processing to finish before freeing the context object, but I don't know how to do that properly. But not freeing the context object in compiz_config_profile_setter.c fixes the problem for me (the cssFreeContext() is called right before the compiz-config-profile-setter exits, so I think it doesn't really matter much). So with this patch the memory gets freed on exiting of the program after the main loop has stopped. ** Patch added: "compiz-config-profile-setter_segfault.patch" https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1758009/+attachment/5212325/+files/compiz-config-profile-setter_segfault.patch ** Tags added: patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1758009 Title: Unity not starting: compiz-config crashes on login To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1758009/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

At first solution 5 did not work for me. A prerequisite I guess is that you have to remove lowgfx.conf file before, not just comment it out.

I resolved the problem for myself.
