The computer is dual boot, and openSUSE 10.2 has been running successfully on it since last December. I have not made any configuration changes, although I do perform updates when they become available. Anyway, starting just this morning the mouse becomes unresponsive when the computer enters graphics mode. It will leave a few "arrows" here and there on the screen, but it is extremely difficult to tell where the mouse is. To be more specific, it is slowed down to about 1/20 of its normal response time and only leaves an occasional image regarding where the mouse is actually "located."

A restart does not help and reinstalling the NVIDIA video driver did not help. When booting into Windows XP Home, it behaves normally, so I believe it is not a hardware problem. As a check, I changed the mouse from a USB mouse to a PS2 mouse and that did not help either. I also ran sax2 to adjust the mouse settings and was not able to discover a solution there.

I would rather not reinstall, since I do not want to do updates for several hours. I suppose I could use this as an opportunity to try out some new distributions, though. Anyway, if someone has an idea regarding what may help solve this problem, I would appreciate it.

that is so wierd my logitech cordless mouse did the same thing in windows today...

i cant get it to work for nothing. but changing to my MS optical mouse (wired usb) works fine.

maybe some logitech sick joke for fathers day ?

The same happened to me too. Yesterday after upgrading SuSE10.2 my mouse is not responding any more. Actually the cursor goes up an down no matter which direction i move the mouse. In Wins it behave normally. Will try PS mouse.

Thanks. I hope someone comes along who knows what we might change to get things working again.

Me too. I reinstalled SuSE and now everything is working again.

Did you try to reinstall the nvidia driver using the shar (.sh) installer from the nvidia site?

Thank you for the reply. If you mean the file you download and run like this:
sh NVIDIA-Linux-x86-1.0-9746-pkg1.run -q
the answer is yes. I did not use an RPM-type package.

Do you have 3D acceleration operating (try google earth or glxinfo | grep vendor; it should be nvidia)? Check whether the kernel module is loaded with lsmod | grep nvidia.

With glxinfo, I get the following:
Error: unable to open display (null)

This one gives me:

Type from a console (konsole or xterm) under X (the graphical interface). Can you post the contents of /var/log/Xorg.0.log?

Thank you for the additional ideas.

export DISPLAY=:0.0
glxinfo | grep vendor

renders the same result (Error: unable to open display (null))

The log file is 2577 lines, and for now, that computer is essentially reduced to command line mode (no terminal window). Just off the top of my head, I cannot think of a convenient way to post it here, as I am not that good using Lynx, although maybe rebooting in Windows and grabbing the file from there may be a possibility. (I will need some time for that.) Is there anything in particular I am looking for?

The commands above should be executed when running under X. In the log you may find out why the acceleration (XAA, DGA) doesn't work in your case.

OK, that explains why my "results" have not been what they should be (slaps forehead). I will see what I can do when I get back to that computer. Thank you for your patience.

OK. I started X and then ran the commands:

export DISPLAY=:0.0
glxinfo | grep vendor

The result was:

Server glx vendor string: NVIDIA corporation
Client glx vendor string: NVIDIA corporation
OpenGL vendor string: NVIDIA corporation

I am still working on a way to post the Xorg.0.log file.
