Mouse pointer stuck at bottom - only moves left and right

[JerryRice]

Hello,

I am using a combo usb wirless mini keyboads and touchpad all in one.
When I start X, The keyboard works great but the mouse pointer is stuck on the bottom of the screen and only moves left to right. I can try to go up, it does about one ince before returning down at the bottom.

Is there a setting to correct this?

Thanks,
Jerry

Seems to point to a defective mouse.

I had an issue some years ago under MS Windows where the operating system defaulted to the wrong mouse driver - Microsoft instead of Logitech - or vice versa, cant remember - and I loaded the correct driver and all was peachy. Not sure how to tell Pi to use a different mouse driver than what it this is the correct one / default one yet though - maybe a Linux guru can post this?

But worth a shot from majongg's comments - to prove mouse is good - does it work OK in a different computer?

[JerryRice]

This keyboard and mouse works great with other computers (windows) and also works great with BeageBoard using Ubuntu.

I also agree and think I have to somehow tell the Raspberry PI which driver.. but I dont know how. Although it does show the correct name of the device at startup.

I am using: iPazzPort model: KP-810-10A

If anyone knows what to do, please help.

I'm getting exactly the same issue. sometimes the mouse will behave normally, and other times it gets stuck on the bottom of the task bar.

I'm also using a combined wireless keyboard/trackpad. Mine is a "Rii" RT-MWK01. which is likely exactly the same as yours! works great in windows, but this debian doesnt seem to like it so much!

I have this problem with the same wireless mini keyboard / trackpad combo. The mouse acts as if it's constantly receiving a down input. Only moving up fast gets it off of the bottom of the screen, as soon as you stop it goes back to the bottom.

[JerryRice]

Its great to know that we are not alone
This is a great keyboard for this device and good for Carputer.


Any ideas on what to do?

[JerryRice]

Hello Guys, I am so new at this type of computing and sorry to say that I have not yet found a way to get this working. Has anyone else get any closer?

[JerryRice]

Just a quick update that seems to work for me so far. Try this:

Plug in all peripherals into a external powered hub. Shut the keyboard power switch.
Power on your RPi

When the log in prompt appears, turn on the keyboard. Log in. Then I always log in as root but I dont know if you need to.

Then command: startx

as it loads and you see the mouse pointer on screen- keep the mouse up high using the touchpad.
That's it, then use as normal.

Seems to work. Please try and post back.

Thank you thank you thank you, may all your childrens children have plenty children! Was just talking about my Rii in an IRC forum. came here to get the link as several folk were interested in it, knowing it didn`t work so well with the RasPi but OK with everything else. Just tested in Wheezy and I know it was problematic before because I tried it. Had the same problem with the sticking cursor in Debian Squeeze too. Did it your way but no admin log in, just normal and it works so perfectly!

I was still well happy with this small keyboard/trackpad but this just puts the icing on the cake. Thankfully I had a full size Keyboard/mouse but I`m tempted to put that away again now. Thanks again,

Steve

Hello,
still have this problem with the new Raspbian Image.
My iPazzPort KP-810-10A works fine with the Debian build from 19 04 2012
any ideas?
regards
Christian

I also have this problem, with the same keyboard. Works fine in windows.... It's intermittent, too. Sometimes it's fine.

I'll run dmesg tonight and see if there's any info... Also, I might run a different flavour of Linux (using Raspbian) and see if that helps.

[JRT]

Ok, for anyone that's interested, here's my findings.

Different power supply, no hub - same problem. HOWEVER - if I disconnect the ethernet, the problem pretty much disappears. I don't think it's a power problem, I think it's a usb/lan conflict of some kind, which would make sense given what I've read about the usb on the pi.

My other keyboards (wireless) all work. Maybe because this is a slightly cheaper chinese knock-off, it has weird driver issues....

[IamTheFij]

So my device is not defective. Thanks for the information. This seems like a pretty strange issue. I got mixed results with and without the ethernet plugged in, so I'm not totally certain that the PI is the issue entirely.

I'm trying to download the RPi VirtualBox image to see if it really is onboard interference or if it's a driver issue. If it's a driver issue, I imagine it can be fixed. Another possibility is that one of the maintainers of Raspbian might be interested in helping debug the issue if we send them a remote given they are so cheap.

[dlesage]

I've actually got the same issue with an offbrand wireless keyboard and mouse.
The keyboard works great, but the mouse will get stuck at the bottom and disappear randomly. If I let the RPI sit long enough, the mouse will begin to function again eventually.

The keyboard and the mouse both work perfectly in another machine.
The mouse has issues whether or not the ethernet is plugged in.

Just another instance of the same (or at least similar) issue. Wireless keyboard with mini trackball. Works fine in Windows but on the RasPi the trackball keeps getting the mouse pointer stuck in the taskbar.
NOTE: It's not just as if there are constant down commands being received. It looks more like the mouse has been 'captured' by the taskbar. Once it happens I can move the pointer anywhere within the bottom few pixels of the screen, but no longer above the taskbar. Could it be an issue with X (focus being kept by the taskbar)?
I usually end up using the keyboard to access the menu. Occasionally the mouse pointer frees itself, but I've not yet fathomed a pattern to this behavior.

Had the same problem with a bunch of mice until I switched to a known good powered USB hub.
In fact, most of my Pi problems disappeared when I switched to powering the Pi through the GPIO
header with decent power supplies which also feed the hubs. One supply is 5V/2A feeding a Pi
and a single hub. Other is 5V/6A feeding a different Pi and 2 hubs. But, make sure you have the
latest kernel and firmware as there are some settings that have been added which may help.

Same problem usin iPazzPort keyboard & mouse.

Solved powering keyboard after RPi (linux full charged)

Maybe the key point should be usb loading

[theoB610]

Had similar problems as all
Two different things worked on different occasions:
1. Unplug ethernet and any other things, turn off boot straight to desktop
2. Plug in keyboard after boot
Both are quite clunky, but they've worked.
What I did was literally try any and every fix I could find.
I hope everyone else gets theirs sorted!

I have been having this problem and might have a solution. I wiggle my finger around the touch pad while startx is coming up. The theory is that the driver needs to see some action to make the correct configuration decisions.

On the other hand, I have now also done an update and an upgrade which brought in newer X software among about 150 other packages.

I won't know for sure if the problem is reliably cured until I have another week or so of experience with using the Rii Mini and RasPi.

[mayaco]

don't know if this will make a difference, but when i had this issue, i simply made sure that the usb dongle for the mouse/keyboard combo was on the top port, and the wireless on the bottom

[JohnWulff]

I'm getting exactly the same issue. sometimes the mouse will behave normally, and other times it gets stuck on the bottom of the task bar.

I'm using a combined wireless keyboard/trackpad. Mine is a DGTEC DG-WKB3001 sold to me by the Australian RPI distributor with an RPI B. I have just put the keyboard USB stick in the top port and the AusPi WiFi dongle in the bottom port as suggested. I also twirled my finger on the trackpad during booting of X. The mouse is now behaving normally for the first time today.

[Dripfree]

Thought id give this thread a little bump and see if anyone has found a solution for this one. I wish I would have read this thread a week ago cuz I just bought the ipazzport KP-810-10A. I've only tried raspbmc so far and it doesn't even boot with the dongle plugged in. I'm going to play around with it some more tomorrow, but I'd thought I'd see if someone could save me some time with a verified solution.

I just ran into this on a particular TV. Setting up the pi, I used a small TV close to the wired network. Once setup, I switched to our main TV. Now the cursor is stuck at the bottom. Same hardware: powered USB wireless scratchpad keyboard mouse.
