possible solution



  1. boot into earlier kernel (4.13 in my case). couldnt login due to unknown issues.

  2. reboot into the latest kernel (4.15, installed by 18.04). hdmi detected :)

background:
I migrated from 17.10->18.04 (kubuntu). on installation completion restart, booting to kernel (4.15), hdmi is not detected (xrandr shows hdmi-1-1 disconnected) .
searched around, didnt find any solution (laptop is dell 3450 latitude, nvidia geforce 830M graphics card, intel onboard graphics card)

Try:



xrandr --addmode HDMI-1 1366x768
xrandr --output HDMI-1 --mode 1366x768 --right-of eDP-1


I have the same issue and in my research I've found this potential temporary solution (the above commands need to be re-run after reboot), but in my case it fails with:



xrandr: Configure crtc 1 failed


But it might work for you.

    Try:

    I have the same issue and in my research I've found this potential temporary solution (the above commands need to be re-run after reboot), but in my case it fails with:

            How to enroll fingerprints to Ubuntu 17.10 with VFS491

            Image
            Clash Royale CLAN TAG #URR8PPP up vote 1 down vote favorite I decided to switch from Windows to Ubuntu 17.10, I meet it like 8 years ago and I didn't decided to switch until now (haha). Well, my actual device is an HP Probook 4540s with a Validity fingerprint sensor (VFS491). The fingerprint sensor worked fine on Windows but I can't get it to work in Ubuntu. The device is recognized as 138a:003d but is not detected as a fingerprint scanner by some apps like Fingerprint GUI. I want to use the fingerprint scanner to log in into my user account in Ubuntu but it doesn't supports fingerprints without special software and the drivers of the fingerprint scanner are available for Windows but not for any Linux distribution. I found something on GitHub (https://github.com/eekpie/libfprint) about the integration of the VFS491 in libfprint and I think it can help but I don't know what to do with it, so that's why I need the help of the community to do it since I am...
