[arch-general] Unstable/Unusably slow Wi-Fi connection with systemd-networkd/wpa_supplicant
by riveravaldez 02 Nov '21

02 Nov '21

Hi, I was using Wicd until a couple of weeks without problems, but because it's been out of repos for a while and generally not maintained/developed anymore I decided to make the switch and start using systemd-networkd. The machine is a laptop Dell XPS 15 L502X (Sandy Bridge) with: 03:00.0 Network controller: Intel Corporation Centrino Wireless-N 1030 [Rainbow Peak] (rev 34) I followed the Arch Wiki without problems and wired connection seems to be working flawlessly. But Wi-Fi is unstable and slow at the point of unusability. I posted on the forums[0] for help but didn't get any until now, so I'm letting the link here just in case someone can give me any hint. In the forum's post I informed the output of terminal, networkctl and wpa_cli status, dmesg, journalctl, etc. Please let me know if I should put the details here (didn't did it just to not make mail extremely long, hope I'm not doing wrong) or add anything else. Thanks a lot in advance. Best regards. [0] https://bbs.archlinux.org/viewtopic.php?id=264608

[arch-general] drill -S . : is core dumping arch specific?
by u34＠net9.ga 18 Apr '21

18 Apr '21

$ drill -S . ;; Number of trusted keys: 2 ;; Chasing: . A drill: ./rdata.c:33: ldns_rdf_get_type: Assertion `rd != NULL' failed. zsh: abort (core dumped) drill -S . Is core dumping arch specific? The above is with ldns 1.7.1-2. To the best of my knowledge, the same command just aborts, without a core dump, with the old Debian ldnsutils 1.7.0-4. -- u34

[arch-general] Heads-Up: gtk3-1:3.24.27-3 breaks signal-desktop
by LuKaRo 02 Apr '21

02 Apr '21

Hi everyone, just a quick heads-up to anyone who is using signal-desktop: Apparently upgrading to gtk3-1:3.24.27-3 breaks its dependency on sqlcipher, causing signal-desktop to read its database unencrypted instead of through sqlcipher. This will fail, causing a "NOTADB" error message in a popup, asking the user to quit or overwrite the database. However, in some cases, the database seemingly still gets overwritten even if the user chooses not to. Therefore, be aware of this bug the next time you start signal-desktop after upgrading gtk3 if you do not want to loose your message history or store messages in plain text. Refer to the corresponding GitHub issues #4513 <https://github.com/signalapp/Signal-Desktop/issues/4513> and #5097 <https://github.com/signalapp/Signal-Desktop/issues/5097> as well as FS#69980 <https://bugs.archlinux.org/index.php?do=details&task_id=69980> in the Arch Linux bug tracker. In hope no one else looses their message history, LuKaRo

[arch-general] MAKEFLAGS and dragon.archlinux.org
by u34＠net9.ga 31 Mar '21

31 Mar '21

I think there are no real machines with 5 cores, or 5 cpus. If dragon.archlinux.org actually has 5 cpus then do skip this message. Refering to https://wiki.archlinux.org/index.php/DeveloperWiki:PKGBUILD.com : It states it describes the build server at dragon.archlinux.org. At https://wiki.archlinux.org/index.php/DeveloperWiki:PKGBUILD.com#Packager_&&… it suggests to use MAKEFLAGS=-j5 https://wiki.archlinux.org/index.php/Makepkg#Parallel_compilation suggets to use the number of cores here. I don't know what the implications of using a wrong number in MAKEFLAGS. Or even if there are any implications at all. Still, why not state the correct number, or use $(nproc)? -- u34

[arch-general] KDE - QjackCtl crashes after latest updates
by Susanne Schneider 23 Mar '21

23 Mar '21

yesterday I ran into some trouble after updating my Archlinux (doing this at least 2 times a week): I startet the jackserver via QjackCtl, changed to the neighbour-workspace to start Ardour, and when I went back to QjackCtl it had crashed, I needed to kill both processes jack and qjackctl from commandline. Hours of investigation later (lol) I noticed, that with fresh installation of Qjackctl the package "qt6-wayland" is pointed out as "optional dependency" in installation log. On my system this package turned out to be mandatory, because after having installed this package my QjackCtl went back to regular behaviour. Now I ask myself: am I the only one running into this trap and wouldn't it be a good idea to make qt6-wayland mandatory for QjackCtl? best suse

[arch-general] Laptop's webcam gets blocked randomly
by riveravaldez 22 Mar '21

22 Mar '21

Hi, I'm having kind of a random webcam unavailability on a Dell XPS L502X (Sandy Bridge) with webcam: ``` $ lsusb Bus 001 Device 003: ID 0408:2fb1 Quanta Computer, Inc. Laptop_Integrated_Webcam_2HDM ``` I already checked [1] but couldn't find no hint in how to diagnose this. Sometimes webcam works fine. There's sort of a permanent static-noise with MJPG format in qv4l2 no matter which frame size I use (sometimes it even crash), and with guvcview using MJPG makes the image unstable if I activate the 'mirror' filter; rest of the time I get a lot of: ``` V4L2_CORE: Error - Couldn't decode frame V4L2_CORE: (jpeg decoder) error while decoding frame V4L2_CORE: (jpeg decoder) error while decoding frame V4L2_CORE: (jpeg decoder) Ignoring empty buffer ``` But using YUYV in guvcview, thou slower, the video seems OK (in qv4l2 it starts with a green screen and then the proper image appears). In the other hand, when the webcam doesn't responds, YUYV in qv4l2 only shows the green screen. The hardware lights indicate that webcam is being activated, but I have no image. When not working, qv4l2 only says: `Hue error: connection time expired`, I don't see any other console output. With xawtv I get: ``` $ xawtv This is xawtv-3.107, running on Linux/x86_64 (5.11.2-arch1-1) xinerama 0: 1366x768+0+0 vid-open-auto: using grabber/webcam device /dev/video0 v4l2: oops: select timeout ``` And with guvcview (YUYV) I have: ``` $ guvcview GUVCVIEW: version 2.0.6 V4L2_CORE: (UVCIOC_CTRL_MAP) Error: The file or directory does not exist ... ALSA lib pcm.c:2660:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.rear ALSA lib pcm.c:2660:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.center_lfe ALSA lib pcm.c:2660:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.side ALSA lib pcm_route.c:877:(find_matching_chmap) Found no matching channel map ... connect(2) call to /dev/shm/jack-1000/default/jack_0 failed (err=The file or directory does not exist) attempt to connect to server failed ...

V4L2_CORE: Could not grab image (select timeout): Resource temporarily unavailable ... ``` The only related message I found on `sudo dmesg` says: ``` [33511.458233] uvcvideo: Failed to query (GET_CUR) UVC control 6 on unit 2: -110 (exp. 2). ``` `sudo journalctl -ex` doesn't seems to show nothing about. System is updated. Any idea on how to pinpoint/diagnose the source of this issue? Thanks a lot in advance! [1] https://wiki.archlinux.org/index.php/Webcam_setup

[arch-general] snapcraft
by Zero 19 Mar '21

Hello All, Has anybody here experience with snapcraft (https://snapcraft.io). It seems to be an alternative installing packages on a (Arch) Linux system. That is an alternative, addition to pacman. Of course I don't want to compromise my Arch Linux system and therefore I am curious if anybody has experience with it ? ~Z

[arch-general] cgroups_v2 and rootless podman
by samirnassar＠posteo.de 19 Mar '21

19 Mar '21

Hello, I am trying to make rootless podman work based off of: https://wiki.archlinux.org/index.php/Podman#Rootless_Podman and I am wondering if I am missing something or if there might be old information in the wiki pages: https://wiki.archlinux.org/index.php/Podman and https://wiki.archlinux.org/index.php/Cgroups https://wiki.archlinux.org/index.php/Podman#Rootless_Podman says: Rootless Podman requires using cgroups v2. See cgroups on how to check whether v1 (default) or v2 is used and how to switch to cgroups v2. So I use the instructions at: https://wiki.archlinux.org/index.php/Cgroups#Switching_to_cgroups_v2 So here is what I did: from /etc/default/grub: GRUB_CMDLINE_LINUX_DEFAULT="consoleblank=0 nomodeseti systemd.unified_cgroup_hierarchy=1" $ ls -al /sys/fs/cgroup total 0 dr-xr-xr-x 11 root root 0 Mar 19 10:56 . drwxr-xr-x 7 root root 0 Mar 19 10:56 .. -r--r--r-- 1 root root 0 Mar 19 10:56 cgroup.controllers -rw-r--r-- 1 root root 0 Mar 19 10:57 cgroup.max.depth -rw-r--r-- 1 root root 0 Mar 19 10:57 cgroup.max.descendants -rw-r--r-- 1 root root 0 Mar 19 10:56 cgroup.procs -r--r--r-- 1 root root 0 Mar 19 10:57 cgroup.stat -rw-r--r-- 1 root root 0 Mar 19 10:56 cgroup.subtree_control -rw-r--r-- 1 root root 0 Mar 19 10:57 cgroup.threads -rw-r--r-- 1 root root 0 Mar 19 10:57 cpu.pressure -r--r--r-- 1 root root 0 Mar 19 10:57 cpuset.cpus.effective -r--r--r-- 1 root root 0 Mar 19 10:57 cpuset.mems.effective ... I also set up /etc/subuid and /etc/subgid : $ cat /etc/subuid administrator:100000:65536 $ cat /etc/subgid administrator:100000:65536 Trying to get podman to work : $ podman info Error: cannot setup namespace using newuidmap: exit status 1 $ podman system migrate Error: cannot setup namespace using newuidmap: exit status 1 When I remove /etc/subuid and /etc/subgid , I get: $ podman info --debug ERRO[0000] cannot find UID/GID for user administrator: open /etc/subuid: no such file or directory - check rootless mode in man pages.

[arch-general] vmware-view config help
by Rasmus Liland 18 Mar '21

18 Mar '21

Dear arch-general list subscribers, would someone here please be willing to help me a bit on configuring vmware-view (vmware-horizon-client in AUR)? In Windows I have a prefs.txt config like this: <?xml version="1.0"?> <Root> <RecentServer serverName="vmware.example.com" mruRSAUsername="rasmus" hasValidCert="true" lastLogInAsCurrentUser="false" localIMEEnable="false" serverGuid="12345678-1234-1234-1234-123456789012" serverCacheDir="C:\Users\rasmus\AppData\Local\VMware\VMware Horizon View Client\App Cache\12345678-1234-1234-1234-123456789012\"> <RecentDesktop desktopID="cn=theofficeoverthere-01,ou=applications,dc=vmware,dc=vmware,dc=int" connectUSBOnStartup="false" connectUSBOnInsert="false" resolutionWidth="0" resolutionHeight="0" remoteSystemDPI="0"> <LastMonitor monitorIndex="0"/> </RecentDesktop> <FileRedirection/> <ShortCuts/> <ShadowSettings FitToViewer="true"/> </RecentServer> <SecurityMode/> <LastLoginAsCurrentUser/> <BrokerJumpList> <BrokerJump BrokerName="vmware.example.com" BrokerArguments="vmware-view://vmware.example.com/?"/> </BrokerJumpList> <DesktopJumpList> <DesktopJump DesktopName="RemoteDesktop" DesktopArguments="vmware-view://@vmware.example.com/cn=theofficeoverthere-01,ou=applications,dc=vmware,dc=vmware,dc=int?&domainName=&desktopProtocol=BLAST&desktopLayout=multimonitor"/> </DesktopJumpList> <sharingList showPromptDlg="true" shareHomeDirectory="false" allowAccessRemovable="false"/> <GeolocationSharingSettings/> <BlastSettings/> </Root> When I try to connect like this vmware-view \ -q \ -s wmware.example.com \ -u rasmus \ -t rasmus \ -n "12345678-1234-1234-1234-123456789012" I get the SMS and almost connect, but fail. I'm so close, yet so far away :-\ The same happens if I change -n "12345678-1234-1234-1234-123456789012" to -n "cn=theofficeoverthere-01,ou=applications,dc=vmware,dc=vmware,dc=int" I have looked at the logs, and have a hunch I might also need to grab a certificate pair also from somewhere to somewhere, or perhaps this hunch is unfounded as I get to step to with the SMS there ... Perhaps someone here is familiar with this ... Rasmus
