Justin Indeed, my bad on that one ! Thank you.
So, apparently there's an issue with lvmetad?
root@solus / # sudo clr-boot-manager update
Generating grub configuration file ...
WARNING: Failed to connect to lvmetad. Falling back to device scanning.
I checked the packages, nothing is broken. Nothing is out of date, and I event tied reinstalling the Linux - current package, to no avail. It still won't boot unless I pick the 4.2 kernel.

      Also having similar issue with solus not booting after update. I can press spacebar and select the older kernal and it boots fine. I also have a nvme drive.

      Girtablulu Yes, same problem here - NVMe and Nvidia hardware, Solus totally went blank recently.

        Not sure if NVMe matters, but I did have problems booting with the open driver. (I have the latest Solus 4.0 on an NVidia laptop which I believe has an NVMe drive.)

        Are these blank screen systems using the "nouveau" default driver? I guess that's built into kernel. If not and you can boot into the older kernel, I've had luck switching drivers via Doflicky.

          Louhy hmm my laptop doesn't have an Nvidia card, and nothing shows in Doflicky. I do remember, however, seeing Nvidia somewhere when I checked for package integrity. I don't know if that's relevant though.

          If other people with Nvme drives have the same problem however, it might be a good clue I guess.

            Ah. Also turns out this laptop has an M.2 drive, but it's SATA. So maybe nvme related...

            Syn lvmetad is a red-herring, you can ignore that warning. Edit: I need to know the exact version of the 4.20 and 5.0 kernels in order to help.

                DataDrake the computer cannot boot with the 5.0.12-115.current.
                The kernel that works is 4.20.16-112.current.
                Thanks a lot !

                    Syn Nothing is popping out at me kernel side, so I'm pretty sure you must have a broken package or something.

                    • Syn replied to this.

                        DataDrake How can I check that? The check broken package command shows everything as "OK". And everything works before update, even on a clean install. The update is causing this. I tried reinstalling the whole system, I can reboot and use it. But as soon as I update, nothing works anymore.

                            Syn No. They already patched that in the kernel. We have a new enough version to not need it.

                                DataDrake I just tried adding nomodeset to the kernel boot parameters. The system then boots, even though its much slower. It also doesn't detect its speakers at first ("dummy output" is shown on the sound menu) and I can't use my fn keys to change volume or brightness or anything.
                                But it does indeed boot with nomodeset, so might it be a problem with the graphic card?
