[Bug 1327659] Re: Compiz freezes when screen is disconnected
reproduced the bug on intel i3-330M HD Graphics, with both default and proprietary drivers, solved by disabling openGL texture compression via compizconfig -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1327659 Title: Compiz freezes when screen is disconnected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/1327659/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1327659] Re: Compiz freezes when screen is disconnected
I did some 'gdbing' and located cause of the issue. The problem (only?) happens when texture compression is enabled. So, if texture compression is enabled GLFramebufferObject::allocate allocates texture that is compressed and apparently mesa doesn't like compressed textures for frame buffer. Oddly enough enabled compression doesn't cause the problem when texture is allocated first time at startup, but only causes problem when it is reallocated when resolution changes. Probably because custom config is loaded at a later stage somehow - but this is not exactly apparent why config is loaded at a later stage. Judging by the log output config should be loaded by the time opengl plugin is loaded. I guess ideally enabling texture compression should not cause such issues. Please let me know if I can provide any other information.
