Following BobRoss suggestion I tried another live CD. Because I saw less reports of this problem on the Arch distro, I went ahead and tried Chakra Linux alpha2 live CD, a distro derived from Arch. I was able to reproduce the bug right from start, but I only noticed it when looking at the kernel log (dmesg). That's because in spite of all the usb resets, the keyboard remained steady and I could type without difficulty. The mouse pointer was at times unsteady but still usable and much less jerky than on Kubuntu. So I could imagine this bug being less noticeable on arch.
Running the chakra alpha2 live CD and playing around, I have seen some instances of the keyboard alone being reset after the mouse was disconnected, but mostly it's the mouse that triggers the problem and gets reset. Doing a tail-f on /var/log/kernel.log, I could notice there was no reset when not using the computer. As soon as I move the mouse (doesn't matter if it's with the touchpad or the external mouse), I see resets returning. Keyboard activity also triggers resets but it's a lot less obvious. I tried several mice from several brands, but they're all the same. I'm not sure which piece of hardware is involved in creating this bug, definitely a combination of various factors. If as Sardar suggests it's possible to systematically reproduce the bug on one piece of hardware, then tracking this bug down may get easier. Included in a tgz file are output from uname -a, dmesg, lspci -vv and lsusb -vv. ** Attachment added: "output from uname -a, dmesg, lspci -vv and lsusb -vv." http://launchpadlibrarian.net/27315380/output-arch.tgz -- Keyboard keys get stuck and repeat (Feisty, Gutsy) https://bugs.launchpad.net/bugs/124406 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
