sorry, i tried with your instructions and it works fine for me. if you could give me a exactly instructions how to reproduce this problem, please reopen it again. Thanks
Please retry and move your mouse around simultaneously. It is easily reproduced on this brand FC3 system.
it's strange, i have tried on many machines here again. it works for me! Does this problem appear under GNOME or XFCE instead KDE ?
Actually, I hadn't tried before you asked... It happens: In GDM, In Gnome, In XFCE, In KDE, At the mingetty console (tty1)... This is clearly more deeply rooted than just the KDE window manager. But given that this happens with gpm as well as under X, I can't blame the NVidia driver. Seems to be more related to the hardware. Thanks for looking into it. I will keep digging and see what I can find. -Rob
ok, it's definitive not a bug in KDE. it seems a bug in kernel (USB driver).
if you're using the nvidia binary driver, there's nothing we can do. complain to them. *** This bug has been marked as a duplicate of 73733 ***
On my Dell Precision 360 with USB mouse this phenomena also happens if pressing the CTRL key and moving the mouse around. Additionally it also happens if pressing the SHIFT key and moving the mouse around. This is really annoying because I have to work with CAE programs where on has to press one of the mentioned keys in order to move the model. Has anybody tried a BIOS update from Dell to cure this bug?
*** JUST FYI *** For anyone who encounters this issue... I just observed the fact that running xorg X as a non-root user I do not experience the above behaviour. The issue appears to only apply to sessions where X is running as root. (Why are you running X as root? Are you NUTS? Wise up! ... like i eventually did ... though I did it so my screen saver /BSOD/ would run, which it doesn't and I have to fight yet another issue argh... Still, it's better without MS! ;) Good Luck.
