Whenever i am typing something, with the exception of the arrow keys and a few other keys, the mouse freezes up. This makes playing games very difficult. Can i get some help fixing this?
Im using a Dell inspiron.
Desktop? Hardware? ie laptop? How are mouse and keyboard connected to machine?? Any hubs involved?
Laptop, touchpad, built in keyboard, no hubs.
And what desktop software KDE/Gnome/something else??
Never heard of this problem before??
If you plug a real mouse do you still see the problem?
Maybe need driver for your trackpad??
Any xorg configs set up??
Try a different user could possible be some weird configuration problem.
Remember we can not look over your shoulder.
You have not said which desktop environment.
If by “mouse” you mean “touchpad”, then:
There is a KDE setting, to disable touchpad while typing. And it is the default. Maybe you can experiment with that.
System Settings –> Input devices
I tried that. the only settings i see are these Imgur: The magic of the Internet
also De is Plasma, but i have other De’s installed as well.
Check the “Touchpad” settings.
thanks. do i need to restart to fix the problem?
disabled, logged out, restarted, nothing.
Btw, the keys that freeze the mouse are only the character keys, space, enter, and escape
Can someone please help?
No, you should not need restart for that.
Sorry that it isn’t working out. I’m not sure what else could be the problem.
Not sure why you can’t enable touchpad while typing via the DE utitlity. In any case, libinput disables the touchpads while typing by default.
Check your touchpad proprieties with
libinput-list-devices|
You’ll find that this is enabled…
Disable-w-typing: enabled
Also via xinput…
xinput
My touchpad is device 11
xinput list-props 11
For reference I get
libinput Disable While Typing Enabled (286): 1
libinput Disable While Typing Enabled Default (287): 1
I can disable that with
xinput set-prop 11 "libinput Disable While Typing Enabled" 0
See if this helps. You can make it persistent by adding to an ‘autostart’ script if needed.
all i get is a rightward pointing arrow like this >
Hi
The first command has a erroneous | press ctrl+c and remove that from the command;
libinput-list-devices
Yes, sorry that should have been ‘libinput-list-devices’ as Malcolm has posted already
If ‘libinput-list-devices’ is not a typo you can use command-not-found to lookup the package that contains it, like this:
cnf libinput-list-devices
someone gave me an external mouse, and the problem does not occur with it.
It’s provided by the ‘libinput-tools’ package, and is a ‘compatibility wrapper which will be removed in the future’.
Anyway, just use the xinput command instead. Then use the appropriate device ID to get the device settings as explained already.
That is as expected. Only the touchpad device can be configured to be disabled while typing. 
x input gives the same cnf dialouge.
