[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

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

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

[arch-general] nvidia causing audio glitches
by Paul Dann 18 Mar '21

18 Mar '21

I've had this problem ever since I got this laptop[1]: I get audio glitches with both pulseaudio and pipewire, through *all* audio sinks (built-in, USB soundcard, bluetooth). It seems to become more severe after a suspend/resume cycle. I've discovered that the symptoms go away completely if I set the discrete NVIDIA graphics card PowerMizer setting to "Preferred Mode: Prefer Maximum Performance". So it seems there's something about the hardware's low-power behaviour that causes this. Has anyone else experienced this? Does anyone have a clearer understanding of the cause? Is this something we can take to NVIDIA with any realistic hope of a fix? Paul [1] Dell Inspiron 7590, Intel Core i5-9300H, GTX 1650

[arch-general] Arch intallation using usb-modem
by Morten Bo Johansen 17 Mar '21

17 Mar '21

Hi I would like to install Arch Linux, but I only have a mobile broadband connection with a usb-modem. Arch installation does not set up that connection automatically, but rather it has to be configured manually from the command prompt. I tried with wvdial but had no luck. What other alternatives do I have? Thanks, Morten

[arch-general] definition of "orphan"
by Matthias Bodenbinder 16 Mar '21

16 Mar '21

Hi, in the arch world I see two different definition of an "orphan". The pacman manpage says: orphans - packages that were installed as dependencies but are no longer required by any installed package. For the AUR the definition of an "orphan" is If all maintainers of an AUR package disown it, it will become an "orphaned" package. (https://wiki.archlinux.org/index.php/AUR_submission_guidelines#Maintaining_… ) This is confusing. Would it make sense to change the wording so that it is not ambiguous anymore. Matthias
