I have been a (reasonably) happy gentoo user for a little over a year now, but decided to give Fedora a try. So I installed Fedora Core 3 a few days ago, and overall am impressed with how well it works. Except for one really annoying issue: Every 3 or 4 seconds, the mouse cursor pauses for a fraction of a second. If that pause happens to fall on a mouse click, it doesn't register. If I'm just moving the mouse, the cursors stops briefly before moving on. It happens EVERY 3-4 seconds. I suspect it may be more than just the mouse, but at least the keyboard doesn't seem to suffer.

I'm running on an HP Pavillion P4 3GHz, 1GB RAM with an nVidiea GE Force (or something like that) video card. It doesn't have the problem on the login screen, only after all the Gnome session finishes loading. I've even removed all the applets from the pannels (except for the default ones) to see if it was one of those. The mouse and keyboard are both USB.

I've done some googling around and haven't found a solution. I upgraded to nVidia's drivers, and that doesn't seem to have helped. Any help would be greatly appreciated. I haven't had this problem on this machine with Gentoo, or SUSE.

Any help would be greatly appreciated.

Just curious mikvo, does this happen when using any of the other WM's like KDE, ice,,,

I have only tried with KDE, but it doesn't exhibit the problem. In fact, if I log out, then log in using KDE (which doesn't have the problem), then log out and log into Gnome, the problem goes away... Until I reboot and log in only to Gnome.

Only a thought, but have you tried running top or ntop, in a console, since I found that a device search service was cutting in and affecting my mouse/cursor.

Yes, I tried that. There was nothing over 1-2% of my CPU, and no specific process that seemed to jump to the top when it paused. Since I don't often turn my computer off, I'll just leave it as is for now, and use the KDE log-in, log-out trick if it happens again. Hopefully. I'd like to know why it was doing it, but I've shut down almost every service and application I could find to shut down and it didn't seem to matter until I had switch to KDE and back. Oh well...

Have you checked the system log (/var/log/messages) and "dmesg" yet?

Mikvo, I have the EXACT same problem...

I'm very new to to Linux, not to mention Fedora. I'll try to find another driver for my mouse. (Linux doe use drivers right...?)

Do you have the same type of mouse by any chance? A Logitech iFeel mouse, optical, usb, corded?

I have the exact same problem - I've had it with SuSE, Mandrake and every other distro I've tried

I think it may be connected to the CD-ROM or the IDE system in general because in the past it doesn't happen until I put a CD in the drive... Its happening all the time now though

I'm using Gnome in Fedora at the moment and it happening here too.

Its not just the mouse though, the entire system freezes - even the red ! next to the clock stops animating for a second. Also experienced it in a text-mode console (no GUI). Its system wide

I found out it's purely a mouse problem on my system.

For some odd reason whenever I push both the left and right mouse button at them same time, the problem is completely gone. So these days I'm pusing buttons whenever I boot Linux and then everything is fine.

Strange but true.............

Bizzare...I shall have to try that

No effect sadly - still impossible to do anything really

I really wanted to use some video tools to record from a TV card etc but thats impossible if the whole thing pauses all the time - you can't use it then

I shall keep looking for a solution but disc space is at a premium and at the moment this installation is useless so I shall remove it in a few days and redistribute the disc space
