Support Ubuntu 20.04 LTS (Focal Fossa)

[willianmacedo]

works on 19.10 when you upgrade to 20.04lts to stop working.

[willianmacedo]

in version 19.10 we already had the problem of disconnecting the displays eventually.

now in version 20.04 LTS general error in the driver.
Failed to build evdi / 5.2.14. Consult /var/lib/dkms/evdi/5.2.14/build/make.log for details ..

[bbrout]

Am attempting to get Displaylink USB/VGA adapter to work on Ubuntu 20.04 with NVIDIA Card. I have filled my video ports with three monitors and need to add a fourth. I have installed Ubuntu driver from Displaylink site and upgraded with xserver patch for 20.04. Still no joy. lsusb "sees" the Displaylink as:

Bus 001 Device 004: ID 17e9:4300 DisplayLink Displaylink USB3.0 Display

but no action on the attached monitor. Am using CableCreation Adaptor.

Attached is the Linux Support tool zip file.

Any help would be appreciated.

Thank you.

After latest Ubuntu updates it seems the problem is back, lagging when laptop lid closed.

[nvergontbij]

Most compatibility issues between displaylink, evdi and kernel vers. > 5.8 have been solved by the evdi branch 1.7.x
Instructions for its installation are reported here:

https://displaylink.org/forum/showth...1259#post91259

Perhaps this might work for you as well.
If not, feel free to report back.

Problem described here (for those who might come to this thread due to same issue):

https://www.displaylink.org/forum/sh...ad.php?t=67537

Tried the fix explained here: https://displaylink.org/forum/showpo...9&postcount=19

Tried the fix with both 5.4 kernel (default in Mint 20.1) and a 5.8.x kernel (via Update Manager). Neither made a difference. Still just blurry lines in correct resolution.

Today I tried to close my laptop lid. Guess what, no lag today. Wonder how long that will hold!
