[Bug 1632197] Re: display freezes after recent apt update/upgrade
An update on the symptoms... Two new manifestations of note: 1) After trying briefly to get the display to freeze by dragging windows on the desktop, and believing that I had failed, I tried switching to a virtual terminal, only to find them all dead (blank screen and unresponsive). When I tried to return to the desktop display, I found that it was frozen except for mouse pointer movement. 2) After working on the desktop for several hours with just one incidence of freezing/reboot, I again attempted to switch to a virtual terminal, to find the screen as I had left it earlier (logged in and grepping a log file), but unresponsive to the keyboard. I tried a number of obvious keyboard sequences and random pecking to no avail, then switched back to the desktop display to find that much of that keyboard input somehow made it to an xterm on the desktop. In other words, on switching to the vt, the keyboard input remained with the desktop. This is all looking very much like a problem with the xserver, but then... Thinking that I would try dragging some windows between workspaces, I hit +s to bring up the workspace switcher, only to find to my amazement that the workspace grid had undergone a vertical rotation. Is this a bug or a feature? With all the random keyboard pecking that had been erroneously fed to the desktop, had I stumbled upon an undocumented "feature" which we shall call workspace grid rotation? If the answer is "no", then unity has a serious problem. If the answer is "yes", then I think there is probably enough evidence to blame the xserver for the other reported problems. This is reaching the point that I am needing to back out of the xserver/compiz/unity upgrade to get back to a stable system. I'll back out one package (or meta-package) at a time, test for stability, and keep going until stability is achieved, and will let you know how it goes. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1632197 Title: display freezes after recent apt update/upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/1632197/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Just a quick correction... With regard to the workspace switcher, +s should read +s... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1632197 Title: display freezes after recent apt update/upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/1632197/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1632197] [NEW] display freezes after recent apt update/upgrade
Public bug reported: After a recent upgrade (which includes linux,xorg-server,compiz,unity...see below), the display periodically freezes and is completely unresponsive to keyboard and mouse (other than pointer movement), after attempting to drag a window across the workspace. This is a problem for both of two modes of window dragging: ++drag and +s then drag. Other than when dragging windows, no other activity on the desktop/display appears to be a problem. The system is otherwise quite stable. But... In addition (and this is also new since the upgrade and probably related), the display and input goes dead after closing the lid on the laptop. This happens whether displaying the desktop, or in a virtual terminal, or when logged out with the login screen displayed. The display goes blank (per the usual), but does not go active again when the lid is raised (bad). The system is configured to "never suspend" and to "do nothing" when the lid is closed and to "never" turn the screen off due to inactivity. The noted behavior is now on exhibit with both the upgraded kernel and the "old" kernel (4.4.0-38-generic and 4.4.0-36-generic, respectively). Prior to the upgrade, this laptop was perfectly stable (booting 4.4.0-36), and (for what it's worth) windows10 (ughhh) is still quite stable, suggesting that this is not a case of hardware gone flaky. I strongly suspect an interaction between the upgraded compiz package and the upgraded xorg-server as the source of the problem, since the underlying system continues to operate even though the display and input are dead (deduced by the fact that scheduled cron jobs run to completion well after the display has gone dead), and because the first problem only occurs when dragging a window. (It would help if I were able to switch into a virtual terminal, but the keyboard is totally deceased.) There is no indication of a problem in the log files that I have been able to discern. However, there is at least one instance of dumped core (so to speak) by upstart in /var/crash since the upgrade. I realize that this is not enough detail to be of much help, and not much of the bug reporting docs seem to apply to this case, so please do let me know what more I can do to assist in tracking down the problem.
