Never had jumping mouse that I recall. My (new) PC using a little KingWin mouse (no longer available); "old" PC using old Logitek; have used other Logitech including one that's now connected to the laptop (the one I could not post /var/log/messages for). Daughter PC using Logitech mouse since her light-up one died. These Logitech mouse are low-end, 3 buttons. Two are identical, that can work I believe a 5-button. Can get mfr part numbers if needed. Keyboards are miscellaneous, mainly slim-type, inexpensive Rosewill (Newegg's own brand) which these seem to be mfr by "Chesen." Can get mfr part numbers if needed. Will try the newer kernel per J. R. Mauro suggestion & check back in. Liz J 2009/4/25 Jason Couture <plaguethenet@gmail.com>:
Ive noticed that logitech mice seem to have strange issues with linux, Example i have a wireless logitech USB Mouse and keyboard, And every so often the mouse freaks out and jumps all over the screen clicks on things while it does and then returns to normal. Next time it happens ill post a copy of /var/log/messages pertaining to the issue, Perhaps your issue is related?
