Not sure if using correct mouse module

English Hardware
1

Hi i recently bought a new cheap mouse because my first mouse wasn’t working right it would click twice sometimes when i clicked. So now i have this new mouse and it almost works right but sometimes when moving the mouse it glitches and skips a few pixels while moving. I think it’s because of the mouse module but I am not sure. How do I fix this?

I’m using a perixx optical mouse m-868. and I’m running kde plasma desktop. Also this mouse is not a usb mouse it is I think whats called a ps/2 mouse it is a small round metal connector instead of usb.

here is the output of lsmod:

@errigour:

Yes, a PS/2 Mouse has a round connector and –

  • It’s designed for a PS/2 connector on your Mainboard.
    And, that connector may or, may not, support either a PS/2 Keyboard or, a PS/2 Mouse.
    More gory details here: <https://en.wikipedia.org/wiki/PS/2_port>

Please be aware that, the PS/2 port doesn’t support hot-plugging –

  • The PS/2 device – either a keyboard or, a mouse – MUST be plugged in when you power the machine on.

If you attempt to plug the device into the PS/2 connector after you’ve powered your machine on, the device will not be recognised – first, the Mainboard has to recognise the PS/2 device and then, the Linux Kernel has a chance to recognise the PS/2 device …

Here on Leap 15.5 with the Kernel version 5.14.21-150500.55.7 –

  • In the Kernel source code:
/usr/src/linux-5.14.21-150500.55.7/drivers/input/mouse/psmouse-base.c
/usr/src/linux-5.14.21-150500.55.7/drivers/input/mouse/psmouse-smbus.c
/usr/src/linux-5.14.21-150500.55.7/drivers/input/mouse/psmouse.h

Please be aware that, the PS/2 mouse support in the Kernel is mostly directed at supporting Touchpad hardware which connects to the Laptop’s Mainboard by means of a PS/2 interface.

  • Here is the list of PS/2 Touchpad (mouse) devices which are definitely supported by the Linux Kernel:
#include "synaptics.h"
#include "logips2pp.h"
#include "alps.h"
#include "hgpk.h"
#include "lifebook.h"
#include "trackpoint.h"
#include "touchkit_ps2.h"
#include "elantech.h"
#include "sentelic.h"
#include "cypress_ps2.h"
#include "focaltech.h"
#include "vmmouse.h"
#include "byd.h"

Where can i buy a mouse that works well with leap 15.4? It can be usb or ps/2 idc just want it to work.

Have had good luck with Logitec wireless. Note these connect via USB

Build date around about 2012.

  • Provided that, you plugged the mouse into the green PS/2 port (possibly with a mouse symbol) before you powered the box on, the PS/2 mouse should function as expected.

It may well be that, you’ll also need a PS/2 keyboard plugged into the purple PS/2 port for everything to function as expected.

On the other hand, there are USB ports on the box and, provided that, both the keyboard and the mouse are USB devices, that could be the better solution for modern keyboard and mouse hardware.

Where to buy keyboard and mouse devices?

  • Not knowing where you’re located on this planet, it’s difficult to make any suggestions.

I bought several Logitec M185 with the following features:

  1. Wireless Plug & Play Connection: The freedom of movement of a wireless connection with the reliability of a mouse with cable - in the office, gaming, with and without mouse pad, on Windows like Mac computers

  2. One year of battery life: the on / off switch and an intelligent sleep mode also help with energy saving

  3. Logitec’s proven reliability: The M185 PC mouse is characterized by high quality and reliability

  4. Tiny USB nano receiver: can remain inserted in the notebook.

  5. The receiver can constantly be plugged in: If you need to remove it, he finds space in the cordless mouse and is not lost

  6. Universal compatibility: This Logitech Mouse is compatible with Windows PCs as well as Macs and Linux.

  7. The nano receiver is located in the battery compartment of the mouse and can be stored there if necessary.

8

Only thing is i don’t like using wireless mice. But I wonder if corded Logitec mice would work.

9

sure
Things that cause problems are mice with special gaming features

10

Wireless is great since battery life has been extended to one year or more. Wireless just works.

Never plug a PS/2 keyboard or mouse into an x86 compatible PC’s PS/2 port when the PC is powered on. Not only will it likely not be recognized, you may destroy the PS/2 port electrically, making it forever useless.

I have Optiplex 110, 200, 260(x2), 270(x4), 280(x3), 320, 620(x3), 745, 760 & 780(x2). Starting with 280, they shipped with no PS/2 port on the backpane. However, there’s an accessory card available for them (most of the time available on eBay) that provides both PS/2 port and serial port for SFF models, and 2 PS/2 ports plus serial port for towers. Starting with the 790 models, PS/2 ports were returned to the backpane.

On none of mine, or any 790s I’ve worked on, have I noticed any mouse type or brand sensitivity in openSUSE or Plasma. They’ve always been reliable with any mouse or trackball that works right anywhere else. Most of the time in mine I’ve been using either a Logitech Trackman Wheel, a Logitech Trackman Marble USB, or a Kensington Orbit - all USB.

Maybe that’s what happened somehow cause i did plug it in while it was on BUT it worked fine for a while and then it just got buggy like it’s hard to detect you would have to use the mouse for a while and then finally notice once in a while it skips while moving the mouse pointer.
