Keyboard Cursor Jumps While Typing
I thought I was imagining things for the last few days but last night I was working on a python script and now I'm absolutely sure the issue is real.
I'm using KDE 4.6.5 from KTown on slackware 13.37 on a new Dell Inspiron 15R Laptop. Any time I am typing in a textbox control, the cursor will jump up and or back at random (seemingly) to a new position and this garbles up my text real bad. I am having to type, really, really slowly to prevent the cursor from jumping to a new position and screwing up my work.
I think I resolved the issue by disabling the keystroke repeat option in KDE but then I can't hold up to go up more than one line, hold enter to go down more than one line, etc, etc. Disabling the keystroke repeat basically makes the computer useless for anything other than web surfing.
Does anyone have any idea how to resolve this or am I just crazy?

Could you be catching the touchpad whilst typing? I know a combination of that and catching the menu key causes me to select and delete text when I first move to some latptops.

That's what I originally thought, I must be hitting the touchpad but no it's been going on all week. If I type like a leper with my hands arched upwards to I'm nowhere near the touchpad it still jumps like that. I don't know, maybe there's some kind of hotkey shortcut or something that I'm hitting when I type that jumps me around.
I need to boot into Windows 7, load Visual Studio and try working on some code and see if it happens there too. If not then I can be 100% sure it's a slackware/kde thing.
Don't know if this will help but I have much the same problem and have solved it using syndaemon. I put a script in ~/.kde/Autostart that reads:
#!/bin/bash
/usr/bin/syndaemon -d -i20
The '-d' is to run as a daemon process and the '-i20' tells syndaemon to turn off the touchpad for 20 seconds after a key has been typed. 20 seconds is probably overkill and could be reduced to something more reasonable.

Brilliant! I'll give that a try after work tonight!
experiencing this exact same issue on a gateway nv-54 like you I thought I was loosing my mind finally my wife was like whats wrong and then I told her she was like sure sure with a wifely smile then she used it this morning to do some stuff. and told me when i walked out 'you know your not crazy there is something wrong. mine jumps randomly drives me nuts. tempted to wipe and reinstall but did some searching and saw this exact same thread so thought I'd ask what your results where. if your still checking.

I wrote a script that unloads/loads the psmouse kernel module. Basically you install xbindkeys (or any key-press hooking program) and configure it to run the script anytime your sequence of keys are pressed. In my case I setup xbindkeys to listen for CTRL+ALT+D and it runs the script anytime those keys are pressed.
It has been a life-saver for me and I think it went somewhat viral because I get emails fairly frequently from people thanking me for writing it
Hope it helps you out!

Reason: xbindkeys
Thanks for that little script. It solved my laptops problem also. On mine, the touchpad worked okay until the machine went to sleep. If I forgot to cycle the touchpads on/off switch after it awoke, I would get the same unwanted movement. And of course, it seems almost impossible to remember to cycle the switch.
As an aside, using the stock 14.0 'huge' kernel, I was surprised that the psmouse wasn't just compiled in. Evidently it isn't as rmmod 'psmouse' does remove the module. Live and learn.
Hi all, I'm new.
I installed Linux as it was what I thought, would be the only option to try to keep-out a persistent, destructive, hacker. I do a lot of writing, mainly on the Internet and the jumping cursor is causing problems even as I type this short post.
I tried downloading the code and running it, but it made not a scrap of difference. For example the cursor would not even stand still for me to enter a password to get into this site.
I'm not a developer, I just need a secure operating system.
Please help!
its not emi have a degree in electronics this is a bug related to specific makers of laptops
I had the gateway nv-54 listed in the thread above and now an acer aspire 4739 and honestly was trying to do an email and almost whipped the laptop across the room and i've never damaged any hardware in anyway in 32 years of computer use.
Can anyone verify this is a bug in a kernel module. the above script works great and is a god send but having to toggle the mousepad off and on in 2015 seems we should have a more built in fix for our mobile pc market.
I love slackware absolutely love it. but its not slackware based have the same thing on kali which is debian to.
I really HATE to put windows back on this laptop slackware is so elegant but this is one of the most frustrating bugs ever. your cursor basically jumps around the field your typing in, randomly copy and pasting or inserting. my wife laughed at me about the gateway nv-54 till I had her try to send an email she handed that laptop back to me her eyes smoldering and me laughing myself to tears
btw so far doing this small post my cursor has jumped 19 times so far. makes it so much FUN.
Robert chuckle now 20.

Reason: typo's
I run 'fix-mouse' each time I start KDE ... it does save me from maddening text pastes and mouse jumping.
You could just put this in your ~/.kde/Autostarts folder and have it executable and then KDE will run it for you automatically every time you log in. I have this done for my mouse to remap my back button (Microsoft apparently reversed the buttons and clicking back on the mouse takes you forward).
