> But after I install some drivers (NVidia you appear to have 2 separate graphics cards: [ 4.893710] nvidia 0000:30:00.0: enabling device (0006 -> 0007) [ 6.034799] i915 0000:00:02.0: [drm] fb0: i915drmfb frame buffer device
my guess would be you're having problems with the kernel choosing the correct graphics device to use, and/or some problem with the driver not correctly updating the screen. I also noticed this: [ 5.535665] Lockdown: Xorg: raw io port access is restricted; see man kernel_lockdown.7 however you said disabling secure boot doesn't help, so that's probably not related. Have you tried uninstalling the nvidia driver package to see if that is what's causing the problem? > Return to the original console by Alt+Fn+F1 Just a note, since you're booting with vt.handoff=7 the active VT should be 7, i.e. Ctrl+Alt+F7 You might also want to try booting with all the possibly relevant params removed, i.e. remove 'quiet splash vt.handoff=7' You could also try adding 'nomodeset' to the kernel boot params to see if that helps. In any case, this certainly looks like a kernel issue, not systemd. ** Also affects: linux (Ubuntu) Importance: Undecided Status: New ** Changed in: systemd (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1925055 Title: Boot stuck in UEFI after enrolling keys for drivers Status in linux package in Ubuntu: Incomplete Status in systemd package in Ubuntu: Invalid Bug description: Hello, I faced the following problem. After the fresh installation of Ubuntu, everything works well. But after I install some drivers (NVidia or VirtualBox) that require key enrolling I stuck on boot. See below detailed description. Normal behavior: 1. Press the power button on Laptop. 2. Enter to Grub menu, select Ubuntu and continue. 3. See boot logo. 4. Successfully boot in Ubuntu. Bad behavior: 1. Install drivers (for example VirtualBox via $ sudo apt-get install virtualbox). 2. Enter a password for Secure boot during installation. 3. Shut down the system. 4. Press the power button on Laptop. 5. Enter to Grub menu, select Ubuntu and continue. 6. See boot logo. 7. System stuck, only black screen and blinking white underscore cursor. After some time I realized that to continue boot after step 7 I need the following. 8. Change console by Alt+Fn+F2. 9. Return to the original console by Alt+Fn+F1 (after that booting continues immediately). 10. Successfully boot in Ubuntu. Issue occurrence: 100%. Removing drivers (apt-get purge virtualbox) doesn't help. Disabling of secure boot in BIOS doesn't help. Expected behavior: To be able to boot successfully. Actual result: Stuck on boot.
