I'd like to unmod myself from !geometrydash@lemmy.world, but I don't see any button to do it, and by quick research the actions suggested do not appear for me.

I don't see an option via a comment of mine:

And neither over the sidebar:

Update 02/2024

The Problem has been solved by disabling TPM in UEFI Setup. TPM seems to be bugged with some CPUs. Before updating the BIOS, TPM was probably disabled by vendor, hence it didn't appear initially.

If you experience freezes right before poweroff, try disabling TPM in UEFI/BIOS settings if it isn't in use.

Symptoms

• Complete Freeze after:

preparing to enter ACPI S5 state
Reboot: Power Down

• seemlingly random (can successfully shutdown maybe 10 times in a row, then suddenly freezes again)
• seems to happen more often as uptime grows
• Case Fans still spin, LEDs and Lights stay on
• Monitors stay on, still react to HDMI/DP Hotplugging (unplug/plug)
• REISUB/REISUO doesn't work
• Disks are already powered off and disconnected
• USB devices (eg. keyboard unresponsive)

Since When

• After switching to Arch and flashing BIOS Firmware 7C88v18 to MSI B460M-A Pro Board
• Arch Linux is ruled out by me since it's very unlikely Userland plays a role, and already used Linux before without the problem
• Gone from linux ~6.2.10 to 6.4.8, Kernel bug unlikely

Attempted:

• Reflash 7C88v18 from a FAT32 formatted partition (USB)
• Add reboot=pci or reboot=acpi acpi=force to kernel cmdline
• run fwupd
• Stop X and wait a bit for processes to clear up (???)
• intel-ucode is installed:

~> pacman -Qi intel-ucode | head -2
Name                     : intel-ucode
Version                  : 20230613-1

• Other threads on the Internet seem to have easier reproducibility (always happening), solutions were about either kernel cmdline or outdated kernel (If I didn't see a thread with my exact problem, apologies)

Hardware Info

~> pacman -Qi nvidia | head -2

Misc

• Did I just miss something obvious?
• I don't want to go back to an outdated BIOS firmware
• lscpu, nvidia-smi and other info added if needed
• I have another device (ASUS Board, similar CPU) with similar arch linux setup (nouveau instead of propietary nvidia there), no problems on that device

This concerns a multi monitor setup with different refresh rates (e. g. 1 with 60hz and 1 with 144hz).

The text below is part of the linked article. If you have both nvidia and picom installed, check both sections.

NVIDIA (propietary)

• Open nvidia-settings
• Go to 'X Server Display Configuration'
• In the bottom right, Click on 'Advanced...' if it says 'Advanced...'
• Make sure anything regarding 'force composition pipeline' is checked off
• Make sure you selected the highest refresh rates possible. You can either select it through the settings, configure it with xrandr or with your DEs Display Settings, is applicable

picom

• Make sure to start picom with --no-vsync

Misc

If it still doesn't work, try settings these environment variables:

CLUTTER_DEFAULT_FPS=<your highest refresh rate>
__GL_SYNC_DISPLAY_DEVICE=<your highest refresh rate display>
__GL_SYNC_TO_VBLANK=0

Find the DISPLAY_DEVICE name with xrandr | grep connected

Add the text block above to /etc/environment (Tip: Use EDITOR=<your editor, if EDITOR is not set anywhere else> sudoedit instead of sudo nano or sudo vim)

-> sudoedit /etc/environment

This covers obtaining the ISO, connecting to Wi-Fi, partitioning, formatting, mounting, installing, setting up encryption and installing GRUB, in one article. Also includes some tips, like quickly mounting from install medium. Maybe this helps someone.

When installing the GRUB version above, I got symbol grub_is_shim_lock_enabled not found and can't boot, so I downgraded back to grub-2:2.06.r566.g857af0e17-1-x86_64. I tried --disable-shim-lock but it didn't help. I don't secure boot and don't use TPM.

Package was pushed just 5 hours ago, anyone by chance ran into the same problem?

EDIT: Tried again today, worked. Problem was likely caused because I installed GRUB into the "arch" NVRAM entry (esp/EFI/arch) instead of the Fallback which my board only supports (esp/EFI/BOOT). To do this add --removable to grub-install. The full procedure is:

# grub-install --removable /dev/sdX ## or /dev/nvme0nX
# grub-mkconfig -o /boot/grub/grub.cfg

To support decentralization and spread, should lemmy.world close registration at some point to prevent a performance overload due to too many users? Of course, if registration is disabled, there could be a hint placed somewhere near that from other instances you can interact with content on lemmy.world just like you had registered on it. There could be a link to join-lemmys instance overview.

I stumbled upon this, but I don't know how it would affect the fediverse. The integrated account migration / moving sounds interesting, but on the other hand, it seems to belong to a company rather than a standardization comitee (W3C ActivityPub). I think it should be prevented that there will be a ActivityPub and AT fediverse that are completely isolated from each other (fragmentation)
