Keyboard and mouse delay while using Linux Mint 18.3 64 bit with the Xfce user interface.

I apologize if this issue has been addressed or a very similar issue has been addressed, a search did not turn anything up, but that may be because I didn’t use a good search term.

This in a new machine that I assembled from parts, I installed Windows 10 and then Linux Mint 18.3 as a dual boot.

The Windows 10 partition does not have a discernible amount of mouse and keyboard lag.

In Linux Mint 18.3, the mouse and keyboard have an unacceptable amount of lag. It doesn’t make any difference if I use wired or wireless keyboards and mice. I have installed Solaar and it’s information window shows that Solaar recognizes both of the Logitech receivers I’m using.

It’s also note worthy that the wireless mouse and keyboard work without noticeable lag on my older HP small form factor 32 bit machine, running Linux Mint 18.1 with the MATE user interface.

I have adjusted the mouse acceleration to zero and the sensitivity to 1Px, the result is a somewhat slowed down pointer / cursor, but still difficult to use. The key repeat delay and, repeat speed are very close to the values recommended by Xfce, blinking is off. There is still a very noticeable delay between pressing a key and the character appearing on the screen / desktop.

From the Linux Mint forums at Linux Mint’s official site:

Try the latest kernel of the 4.13 series*. After installing it, reboot. Update Manager - panel: View - Linux kernels.

My reply after updating the kernel:

...updating the kernel helped and now the system is more nearly useful, that's right, still some response delay. The keyboard still has a considerable delay. The mouse has less delay then previously, still over shoots and is hard to center over smaller action buttons. Again, overall an improvement in responsiveness, regrettably, not yet at the point where the response time is equal to other machines I have.

A good place to start would be to figure out why the machine running Linux Mint 18.3 is using software rendering. Your inxi output for the machine with the performance issues says GLX Renderer: Gallium 0.4 on llvmpipe as opposed to GLX Renderer: Mesa DRI Intel Q45/Q43 x86/MMX/SSE2 for the computer that works fine.

    dsstorefile, What, discouraged from thanking people, how strange. So, although I have been running a Linux rig for a long time, I'm not that proficient with terminal commands. I will need to look up GLX renderer and find out what that means. FWIW; I learned about the inxi -Fxz command over at Linux Mint's site, it's suggested there that including the output from that command is very helpful. I only included the inxi -Fxz output from my other machine on a whim, that may have proved more helpful than I thought. tks Nilo – Nilo Feb 26 '18 at 1:35

Linux Mint 19 supports my processor, so upgrading solved the issue.
