Thanks Christopher. It looks like only 3.18-rc2 is available for utopic at this stage: http://kernel.ubuntu.com/~kernel-ppa/mainline/ Is that worth trying, or should I wait for a newer one to become available?
With respect to regression, this is definitely worse on utopic than it was on trusty: Symptoms are that all X applications become unresponsive to mouse, keyboard becomes unresponsive. Mouse pointer still works, but is confined to screen 0 (it won't move onto the external monitor). On trusty, if I just let it sit there, it would come good after about 30-120 seconds. On utopic, if I don't manually intervene and switch to a text console and back, it never comes back (at least not in the 12 minutes that I waited last time). Switching to a text console and back works extremely slowly, but eventually does the right thing, and everything continues on. Other symptoms are out of order messages in /var/log/syslog (like, 5 minutes out of order), and no kernel oops until I switch VCs. Here's the oops that does occur eventually: https://pastebin.canonical.com/121261/ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1384342 Title: kernel messages intel_crtc_wait_for_pending_flips correlate to compiz hang To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1384342/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
