Mouse Interrupt

[Yippee38]

I just figured out that my MS Intellimouse Explorer is conflicting with my GeForce2. So how the hell do I change it. I looked in modules.conf, but I couldn't find the entry.

BTW, I'm using SuSE 7.2.

How are they conflicting with each other?

Do you have agp and ps/2 setup to use their own irq in the bios?

[Yippee38]

They are conflicting by both being set to the same Interrupt. I have not set them in the BIOS. Windows is working ok right now, so I don't want to risk messing it up if I don't have to. I was under the impression that I could send parameters to the module that would specify the IRQ. I've checked the How-To's, but I don't see anything regarding mice (especially USB). It does have some ideas about where to find the docs on devices and I guess I will have to try that.

YOu can set the irq as you load the module, however the BIOS, which assigns the IRQ's during start up must have put the device on the correct IRQ.

If the Video and mouse are coming up on the same IRQ, The bios is putting them there.

Most motherboards have the option to turn off assigning an IRQ for video. This option would be your best bet as the video is on the AGP bus most often, and does not require an interrupt.

What is the symptom that leads you to believe that this is a problem? ... interrupt sharing is NOT impossible in linux...and actually is less likely to lead to problems .. (save of course with isa pnp stuff... but thats a different story)

The symptom is X locks hard. It does not happen in text mode. Sometimes it locks while loading KDE or Gnome, other times it will work fine for a while, then lock. If it locks during loading, it just stops responding. If it locks later, the screen changes to black and dark green and red bands across the screen horizontally. Any apps that were visible before change the color of the band. In other words if there is a dark red band going across the middle of the screen and I had xterm open, when the band gets to the xterm window, it becomes a green band and maybe goes back to red when it reaches the other side of the window.

This lock does not respond to Ctrl-C, Ctrl+Alt+Bkspc, Ctrl+Alt+Del (which is set to reset the system), Ctrl+Alt+Fx, Alt+Fx or any other keystroke. The only thing I can do is hit the reset switch. (Thank God for journaling FS!)

First try disabling PnP OS in the bios and see if that helps. Worth a shot.
