[arch-general] a couple foldingathome problems
by Jude DaShiell 05 Jul '20

05 Jul '20

One of these would be unique, the package is complaining my video drivers aren't up to date. I don't even know what video drivers should be on this machine and haven't got local linux support to clue me in on this one and me being totally blind I don't usually touch or have any interest in video drivers. If the video driver is wrong, will the work done by the computer be rjected by the foldingathome server? The second problem may be effecting all users of the foldingathome package. How good is this package about cleaning up disk space it no longer needs once a completed job gets sent to the server? I have a 120GB drive that's run out of space. This computer runs solid state so the 3tb sata drive wouldn't work in it otherwise this wouldn't be a problem. --

[arch-general] Dual graphics not working in Lenovo P53
by LuKaRo 29 Jun '20

29 Jun '20

Hi all, My new Lenovo P53 has an Intel UHD Graphics 630 and a NVIDIA Quadro T1000 built in. The HDMI port seems to be wired to the NVIDIA graphics. However, dual graphics is not working. When using the nvidia driver and the nvidia-prime package, I can run games on the NVIDIA card using prime-run. But xrandr only shows "eDP1" (internal screen) and "VIRTUAL0", no external ports are recognized. When using xf86-video-nouveau, xrandr shows several DP and eDP-ports and the HDMI port. However, the ports are always shown as "disconnected", even when a HDMI cable is connected (works on another Arch Linux machine). Furthermore, DRI_PRIME=1 glxinfo | grep "OpenGL renderer" always shows the UHD 630. Any ideas how to debug or fix this issue? Thanks a lot, LuKaRo

[arch-general] Access for ordinary users to USB FTDI devices
by Friedrich Romstedt 27 Jun '20

27 Jun '20

Hi, Since end of 2019 I am using the PyFtdi Python package by Emmanuel Blot to talk to an FTDI chip on some controller board. Documentation of PyFtdi is hosted on http://eblot.github.io/pyftdi/. FTDI (Future Technology Devices International) chips (and similar chips by other vendors) implement an Universal Asynchronous Receiver Transmitter (UART) via USB. This can then be used to send messages to the device and receive replies. According to http://eblot.github.io/pyftdi/installation.html, it is at least on Debian and Ubuntu Linux necessary to write an `udev` rules file in order to permit ordinary users access to such an USB device. I attempted to use PyFtdi on my Arch Linux box (patched daily) as an ordinary user, and successfully talked to the device without any additional `udev` rule. We (Emmanual and me) would like to find out why and how Arch is configured to permit this. As I observed this behaviour, I opened Issue #161 on https://github.com/eblot/pyftdi: https://github.com/eblot/pyftdi/issues/161. There were some posts by Emmanuel and by me, but we didn't achieve anything substantial so far. Furthermore, the question arises if there are more places other than PyFtdi where this result might be relevant. Finally it might apply also to other Linux distributions different from Arch Linux aside Debian and Ubuntu; the documentation of pyftdi maybe could be updated to reflect this. Any pointer is welcome. Best wishes, Friedrich

[arch-general] Locale packages
by Daan De Meyer 23 Jun '20

23 Jun '20

Hi, While working on locale-gen support for systemd-firstboot ( https://github.com/systemd/systemd/pull/15994), I started wondering if it wouldn't be simpler to delegate the installation of locales to pacman instead. I haven't been following the mailing lists for very long so I don't know if this has ever been discussed. I'd imagine Arch could provide a package for each locale supported by glibc and users would install the ones they need. The PKGBUILD would use localedef to generate separate folders of compiled locale files for each locale that would be stored in /usr/lib/locale. This approach is already implemented by distros such as Fedora (and co) and Ubuntu. The main advantage of this approach is that there's no need to set up an entire chroot to run locale-gen when pacstrapping a new Arch system image. This might seem easy but becomes trickier when the image uses a different architecture than the host system since emulation of that architecture has to be set up first. Even if locale-gen had a --root option so using the host's locale-gen would be an option, I'm not sure if there's any guarantee that compiled locale definitions generated by the host system's locale-gen would work with the glibc version used by the image (less of a problem with Arch but the glibc on the host could still potentially be out-of-date compared to the one installed in the image). Being able to install locales with pacman would solve all these problems. Any interest in something like this from the Arch developers? I'd be willing to try my hand at a PKGBUILD for this but I'm not a TU so I'd need some support to get this implemented (if there is any interest at all). (This also doesn't imply that locale-gen wouldn't work anymore, locale-gen stores everything in /usr/lib/locale/locale-archive which would be independent from the files installed by the locale packages, so both approaches should work side-by-side) Cheers, Daan De Meyer

[arch-general] What do you do with pacman.log? Periodically archive? Delete?
by David C. Rankin 21 Jun '20

21 Jun '20

This is more of what is the recommended practice ... for handling pacman.log? Strange question, yes, but pacman.log is one of those that never gets rotated, etc.. The information in it isn't useful after a few upgrade cycles. So what is the general practice for dealing with it? o Periodically delete it? o Split it by year with awk and compress it for?? Historical reasons? o Keep the last year? It not one of those things I've ever thought about before, but grepping (after cleaning up the wide-character right-arrow from 2017/18 timeframe), I checked and I have 5M of log dating back to 2013. It's not hurting anything, but that got me thinking? What do others do with it, and is there any recommended manner for dealing with it? I don't see any reason for keeping much of it beyond what you may be asked to post as part of a bug-report, etc.. which usually wouldn't be more than the last couple of months for most packages.. man 8 pacman doesn't provide any options for dealing with how much to keep or to truncate. -- David C.

[arch-general] wierdest kernel crashes when playing movies via plex
by Ricardo Band 20 Jun '20

20 Jun '20

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Ahoi, I have a server that crashes in a few seconds when I start playing movies with plex and transcode them. Kernel, BIOS and Firmware updates and even changes most of the hardware didn't change anything. I thought maybe on this list are a few poeple that still have some ideas. I wrote the whole problem in much more detail down in the bbs: https://bbs.archlinux.org/viewtopic.php?pid=1911198#p1911198 Do you have any ideas? I'm completely out of them.

[arch-general] need to run previous kernel
by Jude DaShiell 19 Jun '20

19 Jun '20

With grub what should be done when grub boots to run the kernel used before the current default kernel? On the older amd machine I have I tried installing linux-amd and the git site timed out on me twice. I think that was during that last ddos attack though. The newer machine has linux-amd installed and running on it. The current kernel on the older machine that got updated yesterday has a serious speech impediment. This speech impediment effects espeakup and if I can I'm going to find out if it also effects fenrir. --

[arch-general] Issue certificate
by Iyán Méndez Veiga 19 Jun '20

19 Jun '20

Hi all, I've been trying to debug an issue with a personal certificate. At first I thought it was a Kmail/Kleopatra bug because after some updates of KDE Applications back in January I stopped being able to sign emails with it. But lately, after trying in KDE Neon and also in a fresh installation of archlinux in a VM, it seems to work there but not in my old installation. I have carefully checked old configurations (I don't have any .pacnew) and still not working. I have already wrote a detailed explanation in the forum so I will not copy paste here. Here is the link: https://bbs.archlinux.org/viewtopic.php?id=256654 Shortly, this is what I can do in both installations and the result is different although both are Archlinux and up-to-date. rm -r .gnupg gpgsm --import my_certificate.p12 * Open Kleopatra -> Asks to trust root certificate -> Say yes and verify fingerprint of Root CA *Trust level in Kleopatra says "full" in VM and "invalid" in my desktop. *Kmail can sign emails in VM and it fails with the following error in my desktop. "Sending message failed. Could not compose message: Address family not supported by protocol." Any ideas what other packages can interfere with my certificate? In the comments it was mentioned gnutl, p11-kit and ca-certificates* but I have same pacakges installed in both systems (except lib32-* packages in the VM). Thanks, Iyán

[arch-general] dash as default shell?
by Piscium 18 Jun '20

18 Jun '20

Today I set dash as my default shell [1] on two PCs. We will see if I get into trouble. This question was asked years ago but maybe good to ask again. Could dash be made the default shell in Arch? I did some simple benchmarks and dash is much faster than bash, moreover being far smaller there is less chance of bugs. A possible issue is bashisms, however Ubuntu has been using dash as default for 14 years and Debian also for several years so hopefully most scripts have had bashisms removed by upstreams. What do you think? [1] https://wiki.archlinux.org/index.php/Dash#Use_DASH_as_/bin/sh
