2.4 ghz Rii Mini keyboard trackpad issues

Sat Aug 18, 2012 4:49 am

I am having difficulties with my keyboard trackpad combo trackpad. Most of the times I try to use the trackpad, the cursor will jump down to the bottom of the screen and become stuck. I can still move it left to right, just not up. Please advise

You didn't say what Distro you're using but try this. The next time you open the desktop with STARTX be prepared for when it opens. Move the cursor to the top of the screen and hold it there while the desktop GUI continues loading. It should then stop getting stuck at the bottom, by the taskbar. I read this somewhere else and tried it then put my Rii mini keyboard/trackpad back into use. It's worked perfectly ever since.

Are you running a wired keyboard with trackpad directly on the PI?
I hope the current use of the device doesn't exceed 100mA, (because it needs to also have a full hub inside for the trackpad) or you might have problems due to the polyfuses in the PI's USB port, which may lower the working voltage for the peripheral to unacceptable low values.
If however you are using a wireless device then its fine, as the bluetooth adapter itself probably uses far less than 100mA.

In general peripherals using more than 100mA must be powered by an externally powered hub.

I'm using The Debian image, and your fix didn't work, it just got stuck again once I tried moving it.
@other poster, I say 2.4 ghz keyboard in my title, means wireless, so the wired things don't apply to me

Surprising it didn't work, it's worked in all Distros I tried so far. Although theirs more than one type of Rii keyboard/trackpad.

I've tried several more times and when it does allow me to move to the top, the moment I touch it again it jumps to the bottom

Hi fellows, I have a Rii touch N7 and tested it with both raspian and Fedora 17 remix. The solution is still far to come in my case. Yes, it is true that pointing the cursor on the top of the screen gives control on it through the trackpad, but it doesn't last for more than 2 minutes or so.
This was tested on raspian, since here we are given a text login and we write startx on the shell; the Fedora 17 has an automatic X start. I am prompted with a graphical login and, by the time I type user and password, the cursor is suddenly stuck at the bottom of the screen.
It is really sad I had been waiting this keboard to come from China, and when it has arrived to my home I trusted that it would have worked, since in every Web page about this product, it's told that it's fully compatible with Linux systems. I have Ubuntu on my pc and I haven't tested the Rii there still. I will do this and post here the result, in the coming days.

Hi everybody, after a long test on Ubuntu with this model of mini keyboard I found out that it works very well. Touchpad and keys. Thus I thought that the problem might be on RPi's poor default system tools in order to recognize and set the monitor resolution and the refresh rate. The very same pc monitor to which both ubuntu and RPi are connected is set by Ubuntu at 1280x1024, and by Raspian at 1154x898 of resolution. I am going to chase data about it. Feel free to post me any link available to improve the monitor resolution on RPi

I just received my RP and RII 2.4 GHz keyboard. The keyboard works just fine on Ubuntu 11.10 and Mac Mountain Lion but not on Wheezy where the cursor is stuck at the bottom of the display. I did notice that the RP was unable to figure out the display dimensions and wonder if this is part of the problem. I'm kind of a beginner in LINUX. I don't own a USB keyboard or mouse and don't really want to make the purchase. Any ideas?

I just bought this and the mouse cursor gets stuck at the bottom also

i noticed in xorg.conf.d there are 2 "touchpad" configs getting loaded

in /usr/share/X11/xorg.conf.d I have

10-evdev.conf that comments say is a "catch-all" for trackpads/touchpads

and

50-synaptics.conf

which has references to evdev and some numbers

I havent tried adjusting any of them as both of the comment sections say to not touch anything and that these 2 files are auto loaded and installed when touchpads/etc are detected

anyhow i can get it to work after unplugging the wifi dongle, plugging it back in, rebooting, then sometimes it works perfectly, when it works it works forever until rebooted.

then mouse cursor get stuck at bottom again, I wish there was a mouse driver like gdm I could just restart like killall -HUP to force a reset of the mouse driver.

But I don't see anything like that for rasbian.

Anyhow running latest rasbian, on a revision 2 raspi board, on a fully upgraded distro, with a brand new RII mini wireless 2.4ghz combat keyboard/trackpad.

the Rii works on my laptop (windows 7) / my 3 desktops (slackware linux / windows xp / windows 7) and works on my android tablet.

so i know it's not a defective item. And I am using the same powered usb hub advertised on the main site and linked to hundreds of times here: http://www.youtube.com/watch?v=pDA7MxFtoS0

So I know the power is fine, unless it's defective board or OS problem.

Hi, I bought an iPazzPort RF 2.4Ghz and I'm experimenting the same problem as the rest, the cursor stays in the bottom of the screen. The only diffenrence is that I'm not using a usb powered hub.
That could solve my problem?
Thanks.

Hi

I bought an Anker Wireless Handheld keyboard (model KP-810-10A). It uses 2.4Ghz wireless and I've had the same issue with the cursor being stuck the the bottom of the screen. Seems to work fine on my win7 machine.

I tried removing the usb dongle and and put it back in as @cito suggested. Putting it back caused the Pi to reset itself (not sure if this is normal behaviour) but when it re-started the trackpad was working fine. I'm using wheezy, an HTC phone charger as power source and have an Edimax wifi dongle in the other USB port.

I think that this should be brought to a bit more attention, as no suggested fix works all the time (apparently).
I'm experiencing exactly the same thing- cursor gets stuck at bottom of screen, tried different fixes, didn't work.
Possibly try something with raspi-config changing keyboard settings- mine was not on there so I'm not sure what to do.
Can someone with a bit more knowledge give us help?

I'm has having exactly the same problem: cursor gets stuck at bottom of screen.

When unplugging the wifi dongle and plugging it back the touchpad works perfectly.

Then I make a new sd from the last raspberry image and run it for the firts time using the Wiffi keyboard/touchpad and surprisely it begins working fine everytime.

i solved it by removing the dongle from the USB port, than I restarted the raspberry-pi and during the start-up I put the dongle in the USB port.
After starting startx, I was able to move the pointer with the though pad.

I would edit my previous post but its lost in some sort of moderation limbo, who knows how long for.

I am pretty sure this problem can be solved by tweaking the xorg config. I don't have the knowledge to do this but am posting information that may be useful to someone who does:

I have this keyboard, the non bluetooth one. It works fine for me on latest Raspbian. I have framebuffer size set it /boot/config.txt, if that helps. I also use it via a powered hub. It is not interference from WiFi or bluetooth, as I also have both these types of dongle installed.
