I solved the problem. Package libclutter-eglx-es20-1.0-0 was installed. I replaced that package with package libclutter-1.0-0 and now quadrapassel works.
I installed Ubuntu Netbook Edition from daily image shortly after beta 2. I guess that libclutter-eglx-es20-1.0-0 was default package, but I checked now Ubuntu RC image and libclutter-1.0-0 will be installed default, so everything should be okay. @Linus, could you confirm that installing package libclutter-1.0-0 fixes this bug? -- quadrapassel doesn't start: Failed to initialise clutter: Unable to select the newly created GLX context https://bugs.launchpad.net/bugs/561734 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
