Question About Mouse Configuration

archetypal · 05-19-2011, 10:55 AM

I'm using an ASUS K42F series laptop with Slackware 13.37 w/ XFCE X-window on it. For the trackpad, it works whenever I have an internet connection at startup, but if I do not, it does not work. I'm assuming this means that it needs the internet connection to get the appropriate drivers at startup.

Is there files that I can copy or have stored so that the internet connection isn't required? Please & thank you for any information!

Nevermind, it does not seem to be completely dependent on the internet connection. The mouse wasn't working for the longest time as soon as I was not booting with an internet connection. Once I got an internet connection at boot, it started working, for a while. I left the computer on and sitting for a bit, and when I came back to it, the mouse was no longer working. I restarted the computer (with an internet connection) and it's still not working. I was having this same difficulty with KDE previously.

I had a similar problem with a different machine. If internet traffic was going on my usb memory stick worked at full speed. No internet traffic, very intermittent and slow usb access.

The problem was that the BIOS ACPI tables were mis-configured _and_ that usb port and the network port were sharing an interrupt.

Try checking the output of 'cat /proc/interrupts' to see if the port the mouse is on and the internet port are sharing an interrupt. If they are, then you'll probably want to look into how to split them up.

Good luck!

Although I don't really know what I'm looking at in the 'cat /proc/interrupts' I don't show anything that appears to be overlapping...

I read somewhere about this, and tried this:

Code:

If you are running 2.6.34-rc7 or later, create /etc/modprobe.d/psmouse.conf and add the line: options psmouse force_elantech=1

But when I did this, the mouse was completely unresponsive.

Here is the output for cat /proc/interrupts. I don't see anything about a mouse though, or the network

When I got back home, it started working immediately. The only change I made was configuring the wireless internet to connect to my home network. For a test, I commented out the ESSID of my home network, so it wouldn't be able to connect to the internet, and it still worked.

At work which is only about 10 minutes away, I can't get it to work, at home I can't get it to not work

Google got a couple of hits (maybe older ones) that talk about having to mess with xorg.conf to get the mouse to work:

A mini-review of how well it works in linux

I mis-read your original post (sorry). The output of 'lspci -v | more' will probably let you find your mouse and see if and what interrupt it is using. Coupled with 'cat /proc/interrupts' you might find out something, but maybe nothing useful.

Thanks for the information. I tried an experiment this morning, and I think it just complicated things more... Before leaving my house, I put my laptop to sleep, came to work, and then woke up my laptop, and the mouse if working fine now. This morning I tried to boot my laptop with the router turned off (no internet connection) and the mouse still worked fine, at home. From what I can gather, it seems like something at my workplace is causing the mouse not to work, but only if I boot it while at work. This doesn't make any sense to me unfortunately.....

OMG!!!! I think I've found out what the problem was! It has to do with the power!!! If I'm running on battery mode the mouse works fine (I tried rebooting as well). As soon as I plug my laptop in, the mouse stops working fully. If I go to a different outlet, it works somewhat, but not as well as in battery mode.

I'm guessing it has something to do with the grounding??? Does anybody have any idea on this?
