Failed to create /root/.cache Are you running makepkg as root? Not advisable.

Neither the PKGBUILD nor the 'displaylink-driver-$pkgver.run` install script tinker with LD_PRELOAD or fakeroot. Have you set that manually?

Latest version fails to build for me... had to revert the last commit.

 # Update with > updpkgsums

DisplayLink 5.3 is now out. There is a little patch to use it. I used evdi-git instead of evdi because it is the only one who work with 5.6 kernel.

# Update with > updpkgsums

-- 2.26.2

Hmm, I have seen a lot of issues here, but mine is not listed, so here is my experience with DisplayLink. After a system update in September 2019, it stopped refreshing the screen unless I move the mouse or have a video playing somewhere in the secondary screen. I spent many hours looking for a similar problem, and digging into system system logs. No success.

I tried various older versions of the kernel and of graphic drivers. None of them worked - I think that several outdated libraries are required. I tried to isolate them by making partial down/upgrades, but only managed to make my system unstable/unbootable.

I reverted all packages to 2019/08/20 (see "Arch Linux Archive") and could continue to use my docking station for a while. Reverting to mid-September, which is slightly less obsolete, was not working. If you are happy with an extremely outdated system, you could try this solution.

I also tried to upgrade only some packages, such as Firefox, but after a while I could not continue updating them and keep DisplayLink to work. My Thinkpad USB 3.0 Dock is now next to a dry pen - in the trash bin :-(

If you have the same issue as me, just give up.

In any case, I would like to thank all the maintainers who managed to make it work for so long :-)

Hi even with xf86-video-intel 1:2.99.917+895+gcb6bff95-1 I was still getting garbled screen under mouse. I found though in the Arch forum a fix that worked for me. https://bbs.archlinux.org/viewtopic.php?id=250258

Working fine as of intel gcb6bff95, at least while laptop monitor is on. As soon as i close/disable it I drop down to 1ms on connected screens.

• xf86-video-intel-1_2.99.917+863+g6afed33b-1-x86_64.pkg.tar.xz - blank or garbled
• xf86-video-intel-1_2.99.917+892+gc6cb1b19-1-x86_64.pkg.tar.xz - blank or garbled
• xf86-video-intel-1:2.99.917+893+gbff5eca4-1-x86_64.pkg.tar.xz - blank or garbled
• xf86-video-intel-1:2.99.917+895+gcb6bff95-1-x86_64.pkg.tar.xz - Working fine while laptop monitor enabled, 1 ms on connected screens if disabled..

Current setup:

• Kernel 5.3.12
• evdi 1.6.4-1
• X.Org X Server 1.20.6
• xf86-video-intel-1:2.99.917+895+gcb6bff95-1

Unfortunately I can't confirm pogojotz comment. After a full system upgrade, I had to downgrade the xf86-video-intel driver or the system would freeze when trying to start the x-server.

Good news for xf86-video-intel users: I have no issues with blank or garbled screens anymore with the recent update (2019-11-16) to 1:2.99.917+895+gcb6bff95-1
