When the boot stops (probably at not being able to start X), login to tty2 and get some logs. Pacman log to see if the nvidia driver gets installed, /var/log/Xorg logs to see why X fails and full dmesg would be useful.

    Yeah, it stops just before showing any graphic interface.
    Here are two logs, journalctl and dmesg ones:

    It was easier right now to throw them at my Google Drive. Full read privileges.
    About pacman log, I couldn't find any on /var/log. Anywhere else to look for it?

    PS: I just realized I didn't get the Xorg one, brb

    [EDIT] Just uploaded Xorg log on that folder.

      Are these logs when selecting non-free? If not selected, then there will be no pacman.log. Tests are mostly needed for non-free, see if it supports the latest nvidia.
      Nouveau fails, not ready for this hardware:
      Dec 31 14:35:13 localhost kernel: nouveau 0000:07:00.0: unknown chipset (b74000a1)
      Linux 5.10.4 is now in the build repo, next ISO will move to that version, then nouveau should have support for this chipset.

      Second minimal test ISO is up. Much closer to what will be used for the final ISO now.
      Tests did show, non-free Nvidia could work with the latest RTX 30* cards, but the included (stable) 455 driver lacked the database for these cards, thus this ISO ships with the 460 (beta) driver.
      The kernel has moved to the latest, longterm release version 5.10, ISO includes 5.10.4.
      Hardware-detection has been updated to accommodate the new Nvidia version, filesystem, kinfocenter and Calamares were updated to reflect the New Year.
      No new QML modules this time for Calamares, usersq is still stuck with not connecting to the needed config files, so the old users module will stay in use.

      Expect kernel 5.10.7 or 8 to be on the final ISO. For the KDE packages, expect Frameworks 5.78, Plasma 5.20.5 and KDE Apps 20.12.1, so that means another week at least for ISO testing.

      On this ISO you will find:
      Linux 5.10.4
      systemd 246
      gcc 10.2.0
      Qt 5.15.2
      Frameworks 5.77.0
      Plasma 5.20.4
      KDE Applications 20.12.0
      Calamares 3.2.36
      Octopi 0.9.0 with sysinfo & cachecleaner tool

        @demm

        How about wpa_supplicant -> iwd switch, for new iso?

        Not stable enough yet, about 25% percent of boot-ups, iwd starts too early and needs to be restarted to have it working.

        Pity, thank you for the clarification.

        Switch from pulseaudio, jack -> pipewire, it will probably be even more difficult.

        demm
        Good news.
        I've tried the new test ISO on both free and non-free.
        On free, it keeps getting stuck.
        On non-free, it just boots up like always and lets install the system. It keeps giving the "unknown chipset" error, but plasma is loaded and kicking.
        inxi -G says it has 460.27.04 drivers loaded.

        If you need any log, tell me and I'll give it tomorrow.

        Cheers!

          First full ISO is up. Lots of updates since the previous, minimal test ISO. Kernel moved to 5.10.5, Plasma is at 5.20.5, KDE Apps 20.12.1. LLVM did the major 11 update (11.0.1), meaning quite a few rebuilds for it.
          This ISO has Stacer instead of systemd-kcm, should be a nice improvement.
          None of my hardware has kernel 5.10.4/monitor resume from suspend issues, so I can't test if 5.10.5 has fixes for this. Neither can I test if the free option supports the very latest Nvidia cards with the new kernel.

          I can confirm here that kernel 5.10.5 still fails to wake the monitor and resume. Will try other PC later.
          Note: 5.10.5-arch1-1 on same machine (arch OS) resumes OK.

          • demm replied to this.

            nezzie 5.10.5-arch1-1 on same machine (arch OS) resumes OK

            Did that one fail on 5.10.4-1?

              Both intel PC's are fine using Arch 5.10.4.arch2-1. They both failed on straight 5.10.4.1.

              OK, what I expected.
              5.10.6 will get the fix they used in arch-2 (I prefer not to patch kernels in the build repo/linux-next):
              https://www.spinics.net/lists/kernel/msg3788886.html

              This also means the first full ISO will definitely not be a final, linux 5.10.6 will be needed, also the needed Nvidia 460 has now a stable release (current ISO has 460 beta).

              Great stuff Demm 5.10.6-1 working OK now. So far!

              Second full ISO is up, this should be the final ISO for a January release, given off course that no new issues are found.
              The move to linux 5.10.6 and Nvidia 460.32 fixed the known issues.
              Some of the updates since the first full ISO also include new Vulkan packages, Smplayer, NSS, GPSD (which required a few rebuilds) and new Inxi.
