Increase PS/2 touchpad polling rate

br flag

Running Xubuntu 20.04 on a Dell Latitude E6400. The touchpad, listed as "AlpsPS/2 DualPoint TouchPad", feels very janky. evhz says it is polling at 40 Hz. Looking for a way to increase the polling rate. The touchpad feels smoother in the BIOS, so support for at least 60 Hz seems likely.

So far I have tried the following:

  1. Disabled the integrated pointing stick through Settings ("AlpsPS/2 DualPoint Stick"). No change.
  2. Booted with the psmouse.rate=100 option (found here). No change.
  3. Booted with the psmouse.proto=imps option (same link). This increased the polling rate but caused the touchpad to register as a generic PS/2 mouse. Lost touch options and slowed the cursor to a crawl. Not a good fix.

I like to use PS/2 mice on older systems, and they often default to 40 Hz, so I'm used to installing PS2Rate Plus on Windows 98 or digging into Control Panel on Windows XP to increase the polling rate. Looking for something similar that will work for this device on Linux.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
