It looks like v3.8-rc7 may have introduced this bug. Can you test the following two kernels:
v3.8-rc6: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8-rc6-raring/ v3.8-rc7: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.8-rc7-raring/ If rc6 is good and rc7 is bad, I can perform a bisect to identify the commit that introduced this regression. One thing to note, you will need to install both the linux-image and linux-image-extras packages. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1133087 Title: Ubuntu shows grains like screen after the splash from kernel (3.8.0-5) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1133087/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
