Description of problem: I'm using an IBM A20p laptop with a Logitech 3-button PS2 mouse. I upgraded from RH 7.2 to 9.0 and added the mouse (couldn't stand the laptop's built-in pointing stick any more) at about the same time. Now occasionally the mouse cursor freezes, the buttons don't do anything, the mouse just stops working. I have to kill the window system with ctrl-shift-backspace and restart it to get the mouse to work again. Of course this trashes all my processes connected to open windows etc., a big nuisance. By "occasionally" I mean sometimes after several days of having the window system running (I generally leave the laptop online all the time). Version-Release number of selected component (if applicable): How reproducible: Unfortunately I don't know a way to reproduce. I thought it might be caused by the ps/2 mouse getting unplugged from the computer, but that doesn't seem to always be the case. It just happens once in a while without warning. Steps to Reproduce: 1. start X 2. use for a long time, like hours or days 3. Actual results: Mouse stops working Expected results: Mouse should keep working Additional info:
Unfortunately, without having more to go on, we're likely not going to be able to reproduce this type of problem. The transient nature of requiring days to reproduce, and only then randomly, makes it even more difficult. If there is something that you can determine however that is a pattern of some kind, or which could possibly provide additional clues, or if you can narrow it down better to some kind of a test case, it might be possible to investigate it in some way however. Alternatively, it could turn out to be the mouse getting unplugged as you suggested, or a bad cable, bad power fluctuation, APM event weirdness, some kernel conflict issue. It's hard to make an adequate assessment of what such a problem could be caused by though without more info. Feel free to attach your X server log and config file, and /var/log/messages from during one of these problem lockups, and I'll look at them and see if anything jumps out at me. Thanks.
Yes, I understand that not much can be done about this without more data. I entered it anyway to have a way to track it if other people see the same thing. I've had a couple more lockups and still am not absolutely certain that it's not caused by the mouse connector, cable, etc. I've found a way to unfreeze it though: hit Ctl-Alt-F1 to switch the screen away from the window system, then Ctl-Alt-F7 to switch back to the window system. That allows getting control of the cursor back without having to kill the window system and all the processes running from it, which makes this problem less severe. I think that unplugging the mouse and plugging it back in can freeze the cursor, so it needs to be unfrozen as described above. If the software can be made to somehow recover automatically instead, that would be great. Thanks
Since this bugzilla report was filed, there have been several major updates to the X Window System, which may resolve this issue. Users who have experienced this problem are encouraged to upgrade to the latest version of Fedora Core, which can be obtained from: http://fedora.redhat.com If this issue turns out to still be reproduceable in the latest version of Fedora Core, please file a bug report in the X.Org bugzilla located at http://bugs.freedesktop.org in the "xorg" component. Once you've filed your bug report to X.Org, if you paste the new bug URL here, Red Hat will continue to track the issue in the centralized X.Org bug tracker, and will review any bug fixes that become available for consideration in future updates.
