[arch-general] System terribly slow
by riveravaldez 27 Oct '25

27 Oct '25

Hi, I'm looking for some advice trying to pinpoint why or where my system has becoming almost unusable slow. Searching the web I've found some hints but nothing precise enough. Maybe it's a failing HDD, but I'm first posting what I have until now in the hope someone can give some advice. Superficial symptoms are a general slowness. I'm using just IceWM and `startx` to initialize the GUI, and even logging into my account previous to that takes almost a minute to get done. Then any application I launch takes minutes to just start (from IceWM to firefox, from qtox to pcmanfm or geany, etc.). Even navigate the folders tree with pcmanfm takes 10 or more seconds just to show any folder content... Hope some of this helps: $ sudo journalctl -b -exp3 -- Journal begins at Thu 2021-12-02 23:59:31 -03, ends at Fri 2021-12-03 19:50:29 -03. -- dic 03 00:48:43 arch kernel: sd 0:0:0:0: [sda] Asking for cache data failed dic 03 00:48:43 arch kernel: sd 0:0:0:0: [sda] Assuming drive cache: write through dic 03 00:50:39 arch libvirtd[592]: cannot open directory '/home/dell/Software/VMs/TrisquelMini8': No existe el fichero o el directorio dic 03 00:50:39 arch libvirtd[592]: error interno: Falló al iniciar automáticamente el grupo de almacenamiento 'TrisquelMini8': cannot open directory '/home/dell/Softwar> dic 03 00:50:41 arch libvirtd[592]: No se encontró 'dmidecode' en ruta: No existe el fichero o el directorio dic 03 00:50:57 arch libvirtd[592]: No se encontró 'dmidecode' en ruta: No existe el fichero o el directorio dic 03 00:56:40 arch systemd[1]: Failed to start Disk Manager.

[arch-general] Linux server crash causing router switch to stop working
by David Rosenstrauch 16 Feb '22

16 Feb '22

Been experiencing a weird issue several times recently that's got me stumped. A couple of weeks ago, my entire home network went dead right in the middle of a zoom call. Same problem happened again late last night. The problem is intermittent/occasional: everything runs without issue for several days, then suddenly crashes. I figured the issue was a problem with my wifi router, but after much debugging I don't think that's the case. I have a new (Arch) linux server I built a few weeks ago. What seems to be happening is that my server crashes for some reason - and then looks like it's causing the ethernet LAN switch inside my router to stop working. (I verified that when I unplug the server's network cable the router starts working again, and when I plug it back in the router stops.) My best guess as to what's happening is that when the server crashes it's somehow either flooding the network, or sending out invalid network packets, and so making the router inoperable. I have no idea what could cause this, though, or how to fix it. (Or even if this is definitely the issue.) I also have no way to know if this is an issue with my server hardware vs. say an issue in a recent kernel upgrade, since the server is so new. Server is running Arch, and is kept very up to date. It's using the on-board LAN chip on the mobo - Realtek RTL8125 2.5GbE (network module r8169, RTL8125B chip/firmware). Router is a Netgear R8000, running dd-wrt (r47097). Any suggestions welcome! Thanks, DR

[arch-general] Bazel, reproducible builds and the out-of-date packages fcitx5-mozc & fcitx-mozc
by Alexander Michalopoulos 31 Jan '22

31 Jan '22

Hello, This is a request concerning two out-of-date packages in [community] called fcitx5-mozc and fcitx-mozc. I’m not sure if this is the proper channel to address such things, if it isn’t then I apologize. Fcitx/Fcitx5 is an input engine like IBus, and Mozc is a Japanese IME. There used to be more Mozc packages in [community] (e.g. ibus-mozc) but they were demoted to the AUR since a good while back, the reason being that upstream Mozc has opted to adopt Bazel as its build system, which among other things is a pain to make compatible with Arch’s reproducibility goals. It’s the same thing that has also happened with other packages like e.g. the one for Anki, which was also recently demoted to the AUR for the exact same reason. The result of all this though is that, while these other Mozc packages have in the meantime been adopted and kept up-to-date in the AUR by several people, the fcitx5-mozc and fcitx-mozc packages have been kept outdated in [community] since May 2021, in their last known working GYP version (GYP was the build system used before Bazel but was deprecated in favor of the latter). I understand that Bazel is… not a great piece of software, to put it mildly, and that upstream’s choice to use it is less than optimal; but keeping a package in an almost year-old outdated version is even less optimal in my opinion. Not to mention that even though for most people this kind of package (an input engine add-on for a non-Latin writing system) is obscure at best, for some of us it’s part of our everyday life and may even be crucial (for work or education purposes, etc) and thus keeping it up-to-date with upstream is a very desired goal. My request is, since the maintainer of fcitx5-mozc and fcitx-mozc is probably not interested in updating these two packages to their current upstream versions, that they be demoted to AUR packages so they can be adopted and updated by other interested parties (that would be me). Or, if for whatever reason this isn’t an option, that either an effort is made to update them in situ to their current upstream versions (if such an effort is not already underway) or at least that they are renamed to something different (e.g. fcitx5-mozc-legacy and fcitx-mozc-legacy) so their current names can be adopted and used by new and up-to-date packages in the AUR. Thanks for reading.

[arch-general] headless box audio with pipewire
by Javier 31 Jan '22

31 Jan '22

Hello ! I have a box, where I can login through SSH, start ncmpcpp to play something with mpd, and then logout, leaving the box playing music, but with no user logged in. At times, I also want to start Xorg (eventually Wayland), and use pipewire for sound and even using bluetooth audio devices (easy with pipewire/pulse). While logged in, I can use pipewire even in console. But once logged out, sound is gone. So pipewire doesn't really work headless by default, is there a way to make it work headless (no one logged in, and still having audio enabled and playing music for example), how so? With alsa, no pipewire, no pulse, all this is pretty simple, since it executes as root, headless audio (no one logged in), audio on console (no Xorg, no Wayland), audio on graphical environmet (Xorg or Wayland). Complex thing with alsa, like using bluetooth devices, or selecting devices is complex. An alternative would be having an easy way to use bluetooth devices with plain alsa (no need for command line for example, since not all users will be able to do that). I think bluez-alsa-git on AUR can help using bluetooth audio devices with plain alsa, but it's somehow complex for non CLI users. Perhaps it's easier to get a box, which when headless, somehow allows alsa to work, and when logged in, pipewire/pulse takes over. But things don't work that way when pipewire/pulse is present, audio is gone when not logged in. Thanks ! -- Javier

[arch-general] Can't mount vfat filesystem
by Jeanette C. 22 Jan '22

22 Jan '22

Hey hey, I just updated my system yesterday and now I can't mount a VFAT filesystem. Installed packages: linux 5.16.2.arch1-1 util-linux 2.37.2-5 There is no mount.vfat or mount.fat program/script and apparently no kernel module installed that contains "fat" in its name. Is there a change in the way to mount such filesystems? Best wishes and thanks for any hints, Jeanette -- * Website: http://juliencoder.de - for summer is a state of sound * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * Audiobombs: https://www.audiobombs.com/users/jeanette_c * GitHub: https://github.com/jeanette-c Baby, there's something about you Show me, that nothing can hold you down <3 (Britney Spears)

[arch-general] Grub installiert issue
by Frank Zimmermann 19 Jan '22

19 Jan '22

I'm doing my first Arch install on an UEFI system and have troubles with GRUB. Following the instruction on the Wiki grub-mkconfig complained about a missing /boot/grub/grub.cfg.new. So I manually created a grub.cfg file but when rebooting Grub says error: unknown file system. In rescue mode I type set root=(hd0,gpt1) set prefix=(0,1)/boot/grub insmod normal error: disk '0,1' not found set prefix=(hd0,gpt1)/boot/grub insmod normal error: unknown filesystem set prefix=(0,gpt1)/boot/grub insmod normal error: disk 0,gpt1 not found My efi partition is the first partition on the first ssd. I think I did all I found on the Wiki and search on the web but am lost now with generating the grub.cfg Any hints please? Frank
