6.1 | 1 | = Fix Touchpad Not Responding After Resume = |
| |
1.1 | 2 | |
| |
6.1 | 3 | On some laptops equipped with a Synaptics RMI4 SMBus touchpad, the touchpad fails to respond after resuming from suspend. The kernel log displays the following messages: |
| |
1.1 | 4 | |
| 5 | {{code language="text"}} | ||
| 6 | rmi4_smbus: failed to get SMBus version number! | ||
| 7 | rmi4_smbus: Failed to resume device: -6 | ||
| 8 | {{/code}} | ||
| 9 | |||
| |
6.1 | 10 | == Identify the Affected Module == |
| |
1.1 | 11 | |
| |
6.1 | 12 | To verify that your hardware is affected, run the following in administrator mode: |
| |
1.1 | 13 | |
| 14 | {{code language="bash"}} | ||
| 15 | dmesg | grep -i touchpad | ||
| 16 | dmesg | grep -i rmi | ||
| 17 | {{/code}} | ||
| 18 | |||
| |
6.1 | 19 | If the second command outputs errors such as the following after resume: |
| |
1.1 | 20 | |
| 21 | {{code language="text"}} | ||
| 22 | rmi4_smbus 0-002c: failed to get SMBus version number! | ||
| 23 | rmi4_smbus 0-002c: Failed to resume device: -6 | ||
| 24 | {{/code}} | ||
| 25 | |||
| |
6.1 | 26 | the solution described here applies to your situation. |
| |
1.1 | 27 | |
| 28 | == Solution == | ||
| 29 | |||
| |
6.1 | 30 | Two files are provided here: a bash script that creates a SystemD service, and a desktop file to run it from the menus. You can install them in two ways: |
| |
1.1 | 31 | |
| |
6.1 | 32 | * System-wide for all users |
| 33 | * Locally for your user only | ||
| |
1.1 | 34 | |
| |
6.1 | 35 | Here is the content of the two files to create and install: |
| |

| 43 | # Fix touchpad not responding after resume from suspend, | ||
| 44 | # for devices using the Synaptics RMI4 SMBus driver (rmi_smbus). | ||
| 45 | # Tested on HP EliteBook 840 G1 running AnduinOS. | ||
| 46 | # | ||
| 47 | # This script creates and enables a systemd service that reloads | ||
| 48 | # the rmi_smbus kernel module after each resume from suspend. | ||
