I have the same problem with i915. X crashed shortly after initiating suspend which results in gdm/kdm login screen. After that changing to text console isn't possible anymore because of a black screen. Sometimes it seems to happen on dpms activation too.
At least in my case Suspend works fine until XV is used (first XV usage results in a short flicker). I still using Overlay because the tearing problem isn't gone. ** Summary changed: - Xorg crashed with SIGSEGV in drm_intel_bo_unpin() + [i855 i915] Xorg crashed with SIGSEGV in drm_intel_bo_unpin() -- [i855 i915] Xorg crashed with SIGSEGV in drm_intel_bo_unpin() https://bugs.launchpad.net/bugs/345796 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
