I am experiencing something similar in Intrepid with kernel 2.6.27-4-generic, on a Macbook Air 1,1.
The problem seems to only occur after resume from suspend to ram. The key strokes are never lost, only strangely delayed into X, or out to the screen. Typing in an xterm for intance, it happens every now and then that nothing is seen, until either return or backspace is pressed (works 50%), or a change to and back from another window is made with Alt-Tab (works 100%). I have not been able to distinguish yet whether the events enter X but are not displayed, or if they get stuck on the way to X. Maybe one hint is that moving over to a text console, some parts of the present page takes a while to update; thus it might be a graphics problem, but I could not tell for sure. I am attaching the output of dmesg and Xorg after resume. (the stack trace is due to the new wl driver, I doubt that is the problem here) ** Attachment added: "dmesg-and-xorg-after-resume.dat" http://launchpadlibrarian.net/17932358/dmesg-and-xorg-after-resume.dat -- suddenly keyboard event recognition gets really slow https://bugs.launchpad.net/bugs/227359 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
