recommendations for touchpad on F34/gnome 40??

Serial, USB, or PS2 port?  I assume you have a desktop.  I'm retired, but used to

work with oceanographers.  Computer mice are non-starters for a research vessel,

so we tried a wide range of options -- touchpads, trackballs, keyboards with touchpad,

and Wacom tablets.  The Wacom Bamboo tablets where popular and seemed to

work with everything, but had more features with Windows drivers.   Now everyone

who doesn't need expansion cards for some instrument uses a laptop.

My old desktop has PS2 and serial ports. I have a Cirque GlidePoint Trackpad Desktop Model GDB220

(4 buttons, serial cable with a PS2 adapter).  I use it with the PS2 adapter so the serial port is available

for other devices.   On a newer desktop a USB<-->serial adapter did not work.  What does work for me

is serial<-->PS2<-->USB (2 adapters!).

I don't have scrolling or gestures, just basic move pointer and click functionality.  Since I

spend most of time in emacs, I don't miss the newfangled features.

The Adesso Smart Cat, 4 Button Glidepoint USB Touchpad (GP-410UB) is similar

and one reviewer said it works with linux, but reviews have many complaints of poor build

quality so I'm looking for another option.  ALPs also sells "GlidePoint" devices, including

modules used in laptops.  Google finds lots of issues for linux users: controlling pointer

sensitivity, missing newfangled features.  If you have access to a computer flea market

or local user group you could ask to try whatever people have in their junk boxes.

At my work I had a Alps keyboard with PS2 and USB connectors and a built-in touchpad.

I liked having the touchpad in a fixed location relative to the keyboard, but would have

preferred the touchpad on the left as I often use my right hand to jot down notes or turn

pages in a reference manual. 

<https://www.adesso.com/product-category/keyboards/touchpad/> has a variety of

keyboards with integral touchpads.
