  • Thanks for the links! I updated my config from z3fold to zsmalloc and adjusted the vm.page-cluster to test these out.

    Reading a bit more, I think when using large max_pool_percent (>30) with Zswap the two solutions are more similar than not. A crucial difference is what use-case is more acceptable since Zswap can cause unresponsiveness (and potential lockup) under high memory pressure. While Zram could result in an OOM crash in a similar worst-case scenario.

    Most distros use systemd and its logging solution: journald. You can use journalctl to read the logs around the time of the crash for e.g.:

    • journalctl -S -5m this shows the last 5 minutes. Use this when a game crashes but the system continues working and did not reboot.
    • journalctl -b -1 -S -10m this shows the last 10 minutes from the previous boot. Use this if the crash froze the whole system and rebooted.

    Look for red lines (errors) and what wrote them. AMD GPU faults usually have the ‘amdgpu’ mentioned, memory errors could appear as ‘protection fault’.




  • Filesystem permissions

    For many apps it is not an issue and provides additional security but in other cases it’s very annoying and not trivial to fix.

    Example1: opening a .docx from Thunderbird flatpak with OnlyOffice flatpak does not work out of the box.

    Example2: mpv and VLC flatpaks work well for local files, but fail to open network shares from Dolphin.

    I think a possible solution would be runtime permission dialogs when denied access.


  • I understand the need for better balancing the power generation and usage and it will be even worse as the unpredictable renewable sources keep increasing.

    Dynamic pricing is just one solution and I would support it when home batteries become more affordable and sustainable. Grid scale energy storage has more benefits than each home having individual batteries while the production scales up.

    Another approach would be dynamic load adjustments. The concept of “packetized” energy in general is very appealing but it would need standardization and utility support.
