A collection of Linux related stuff I do in situations

Mouse cursor freezes after waking up from being suspended

Create a script in /usr/local/bin/psmouse-fix

#!/bin/bash

/sbin/modprobe -r psmouse
/sbin/modprobe psmouse

Make it executable

Create a systemd service in /etc/systemd/system/psmouse_fix.service

[Unit]
Description=Fix freezing psmouse
After=suspend.target hibernate.target hybrid-sleep.target suspend-then-hibernate.target

[Service]
ExecStart=/usr/local/bin/psmouse-fix

[Install]
WantedBy=suspend.target hibernate.target hybrid-sleep.target suspend-then-hibernate.target

Enable the service

systemctl enable psmouse_fix

Installing displaylink on Fedora 35

Install dependencies

sudo dnf install make rpm-build gcc-c++ libdrm-devel

Clone displaylink-rpm

git clone https://github.com/displaylink-rpm/displaylink-rpm.git

Install displaylink-rpm

cd displaylink-rpm
make srpm

This creates rpms in i386 and x86_64.

Install the rpm

cd x86_64
sudo dnf install ./displaylink-1.9.1-2.x86_64.rpm

Starting the systemd service fails with:

Dec 22 22:56:52 colors modprobe[57987]: modprobe: FATAL: Module evdi not found in directory /lib/modules/5.15.10-200.fc35>

Install patched evdi driver

git clone https://github.com/nilathedragon/evdi

Copy evdi sources to dkms directory

cd evdi
sudo cp -r module/* /var/lib/dkms/evdi/1.9.1/source/

Install evdi

sudo dkms autoinstall
