Hmm, it's not:
The last modeset does: [ 18.523525] [drm:ironlake_update_plane], Writing base 02AC7000 FFFFFFFFFFFF7400 0 0 12800 but later we do a quick fbset: [ 28.810380] [drm:ironlake_update_plane], Writing base 00072000 00000000 0 0 7680 i.e. the framebuffer is now too small for the mode. Do you mind attaching the Xorg.0.log so that I can confirm versions? And perhaps quickly trying -intel-2.21.7 to be sure... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1161112 Title: Raring regression: SNA fails completely; UXA causes random hangs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1161112/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
