There was a public holiday here in Bavaria / Germany, so sorry for the delay… Yup. On Ubuntu / Debian plymouthd is started via an initramfs-tools script (/usr/share/initramfs-tools/scripts/init-premount/plymouth), so you get a nice splash screen for cryptsetup. AFAIK that splash doesn't work without a DRM device, so if I kick the i915.ko module from the initramfs, I get no splash but still plymouthd is started (hook script goes to /etc/initramfs-tools/hooks/) I updated my system, and now I always end up with black screen (still Ubuntu 16.04 with a kernel 4.18). In the "early case" I get the splash until some point. Then I can manually change the VT from 1 => 2 => 1 and it re-appears. In the late case, now all VTs are black. I both cases 'plymouth --quit' quits plymouthd and restores the VTs, which would normally happen anyway, as I disabled that services to see the splash after boot. All this might be a user space problem. Probably some timing changed due to the new packages. Normally a systemd service would stop plymouth, which I changed to /bin/true for the testing. If you have any other idea for me to test, feel free to ask me.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
