  1. Linux software to control my Logitech web cam?

    I switched over to Windows today for a Zoom call. Before I did so, I installed the utility application from Logitech to control my camera (a C900, I believe). That allows me to pan the camera and...

    Are you hosting these sessions? How many participants? In our experience the host's bandwidth and computing power can matter quite a bit.

    [ubuntu] Re: i do not have cd rom anymore

    Remove, or comment out with a leading hash mark ("#"), the CD-ROM entries in /etc/apt/sources.list.

    Most of these problems come from the fact that 19.04 ("Disco Dingo") reached end of life in...

    You can daisy-chain the routers by connecting the WAN port of the second router to one of the LAN ports on the first router, then giving it an address in the first router's network, 192.168.1.0/24 in...

    I don't know if cloning will work; never tried it myself. But you could download a brand-new ISO image of Windows 10 and install it on the SSD if you still know what your Product Key is. (Most...

    Re: Transmission permission denied

    You might want to check the integrity of the btrfs filesystem. If a filesystem has errors, Linux will mark it read-only. Can you write other files to that filesystem using the same username as...
  10. Re: Nextcloud, Apache & Letsencrypt in Ubuntu 18.04 server

    NIce. My servers run CentOS 6 so they're not using systemd. At the time I created them at Linode I didn't want to deal with that, so I stayed on an earlier release.

    What about GIMP? It will import PDFs.

    As for the background, I wonder if it might be a mismatch between the RGB and CMYK color models. I bet Avery uses the latter. If this is the issue, you...

  14. [server] Re: Ubuntu Server 19.10: WOL not working

    Are you building a server with WOL? My servers are always available 24/7. To my mind, that's part of the definition of a "server." Usually WOL is a client-side technology.

    We need more details. How is this PPTP connection set up?

  17. Re: Nextcloud, Apache & Letsencrypt in Ubuntu 18.04 server

    I would dump the snaps and use the regular version of Apache, then install certbot from https://certbot.eff.org/.

    [ubuntu] Re: VLC doesn't play V_AV1 codec video

    To pass parameters like "-vd codec" to mpv in SMPlayer I believe you need to add them via Options > Advanced > Mplayer/mpv. I've never tried using them on the command line.

    [ubuntu] Re: VLC doesn't play V_AV1 codec video

    See if it works by forcing mpv to use its av1 codec. It could be a problem arising from the naming scheme used by the video:

    To see all the codecs...

    No one should be using PPTP these days. It has well-known security issues.
