Public bug reported: Following a clean installation of XUbuntu 24-04 (updated) and then "apt update" and "apt upgrade"
I did "apt install cryptsetup" and hand editted /etc/crypttab and /etc/fstab to point to a pre-existing encrypted partition that had been created using the same methods. Then I re-booted. During boot, there is a brown text box, but it seems the keyboard is not recognised. So instead I use the recovery mode on both screens ("advanced options" and "recovery mode") and type the password amongst the boot log text. Then login proceeds correctly, with the encrypted partition mounted and readable. But in addition to this, the Fn-F8/F9 keys, which without cryptsetup controlled the screen brightness, no longer do that. Moreover, in Settings/Display, the laptop screen, which had been called "laptop" without cryptsetup, is now called "None". Also, an external LCD monitor connected by an HDMI cable, which had been recognised without cryptsetup, is no longer recognised. ** Affects: cryptsetup (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2114156 Title: crypttab breaks display controls To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cryptsetup/+bug/2114156/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
