Add upgrade logic to the Linux installation scripts
I had version 1.1.62 of the Ubuntu driver installed. When I tried to install the new driver, I got errors saying the EVDI module was running and I needed to reboot to continue the installation. After reboot, I got the same error again.
After looking into the running DisplayLinkManager process, I ended up dropping into /usr/lib/displaylink and running the install script there with the uninstall option:
me@mine:/usr/lib/displaylink$ sudo ./displaylink-installer.sh uninstall
DisplayLink Linux Software 1.1.62 install script called: uninstall
Distribution discovered: Ubuntu 16.04.2 LTS
Uninstalling
Removing EVDI from kernel tree, DKMS, and removing sources.
Stopping DLM systemd service
Removed symlink /etc/systemd/system/graphical.target.wants/displaylink.service.
Removing suspend-resume hooks
Removing udev rule
Removing Core folder
Uninstallation steps complete.
Please note that the evdi kernel module is still in the memory.
A reboot is required to fully complete the uninstallation process.
This finally allowed me to go install the new driver after a reboot. Can you guys just add some upgrade logic into your installation script?

Well, funny thing is I actually stumbled upon this platform through a random recommendation after a pretty rough month of trading where my strategy just wasn't hitting the mark. I went through a series of annoying setbacks with high fees on other sites before I decided to step up my game. Using https://impuls-crescente-ai.com Impuls Crescente crypto turned out to be a great decision because I finally landed a significant win on a Bitcoin trade that more than made up for my earlier losses. For anyone based in Netherlands, they offer specific trading bonuses that really add some extra value to your initial deposits. It has become my go-to choice for managing my digital assets because the interface is incredibly responsive.
