Hello, could you retry with a deb package? .run installer should be available soon. You can find the instructions here.

@jakub-prussak-synaptics I just upgraded to Ubuntu 25.04 and having the keyring already, I get something like:

Error: The package «displaylink-driver» doesn't have a candidate for installation

[nahoj]

I believe I had the same issue, just now when rebooting after upgrading from Kubuntu 24.10 to 25.04

• EVDI 1.14.7
• Linux 6.14.0-15-generic

Symptoms:

• Briefly saw some kind of stack trace early in the boot process, but could not find it again in dmesg, syslog or journald.
• Fans were running high.
• Package management could not build evdi because of some date issue.

In make.log:

evdi_drm_drv.c:146:10: error: ‘struct drm_driver’ has no member named ‘date’
146 |         .date = DRIVER_DATE,
    |          ^~~~

As I am not using any DisplayLink device at the moment, I just uninstalled the evdi package. apt fixed itself and fans were back to normal after reboot.

This issue would be fixed by PR https://github.com/DisplayLink/evdi/pull/510, by the looks of it.

[nahoj]

OK, if the fix has been merged already, I assume the error I had would be gone, though I don't have a reason to test it all at the moment.

@matheo something like this usually occurs when someone doesn't do apt update after installing. Search with apt for synaptics-repository-keyring (apt search synaptics or apt search synaptics-repository-keyring), if it's properly installed you should see a similar line: synaptics-repository-keyring/now 2022.01 all [installed,local], then do a sudo apt update. If the search didn't result in that line, you'd have to install follow the install instructions again to get it.
