LMDE 6: Touchpad Scroll Too Fast/Sensitive

[TJ_Fitz]

Hi all, just installed LMDE 6 on my Lenovo T450s, and my touchpad two-finger scrolling is also too fast . But this is what I got when following the advised steps:

Code: Select all

root@LMDE-TJ-Lenovo:~# xinput
Unable to connect to X server

What now?

You don't have root account enabled by default on LMDE.

I have a Lenovo E530 (2012) and found the only sane way to get the trackpad to behave was to make sure I had the xserver-xorg-input-libinput driver installed and then delete the xserver-xorg-input-synaptics package.

Still have sudo su.

The former was already installed, and the latter was not. :-/

For starters, what I'd like to know is why I can't connect to the x server on root!

Still have sudo su.

You have enabled root account --- you did not run any sudo su, TJ_Fitz
Command prompt would have been root@hostname:/home/<username>

You have to log in to your root account in X to run an X server on it...
Terminal is just stating the facts: you didn't run an X server on your root account at the time you typed this command.

If you had executed sudo su and then xinput, you should have been able to see the output of xinput because sudo su would have allowed your current user to run commands with elevated privileges and you could have been able to see events registered for this user as a consequence which is totally useless of course because you don't need any special privileges to run xinput

I've never needed root privilege to view or modify xinput parameters, but these
get reset at boot. Even for sudo -su xinput

Hi,
Maybe I didn't understand what you're looking for, but did you try to move the speed cursor reachable through LM Menu / Mouse and Touchpad / Touchpad tab last line. There's also a scrollbar just above to choose what kind of scrolling you want to set.

Sorry for the delayed reply. I haven't forgotten!

Thanks, I've done that. That bottom bar controls how fast the pointer moves when using the touch pad. I doesn't appear to have any effect on two-finger scroll speed.

You have enabled root account. sudo -su is switching you to root in this case.

This is from a vanilla Debian Bookworm system I'm sitting in front of right now where root account is not enabled

Alright, I see where I went wrong. I should have entered

Code: Select all

$ sudo su

instead of

Code: Select all

$ sudo su -

Running xinput without sudo gave this:

Code: Select all

My apologies for being thick

Anyway, what do I do with this info now?
Ps: What does the dash do anyway? I saw "sudo su -" elsewhere as a way to get admin access on the live usb.
