Virtual background for Zoom video
by Paul Smith 14 Feb '21

14 Feb '21

Dear All, I would like to replace the background behind in my webcam video feed with an image. However, that is not possible, as it requires a “green screen”, which I do not have. So, my idea is to use a virtual camera with a background image chosen by me and feed that into Zoom. Is that possible on Fedora? Thanks in advance, Paul

Networking issue in VMs
by Adam Mercer 14 Feb '21

14 Feb '21

Hi I've started having a strange problem the last couple of days with my VMs, I use both VMWare Workstation and VirtualBox on my Fedora 33 system and recently the network connectivity inside my VMs stopped working after some point. I installed an Ubuntu VM, in VMWare. and was using it for several days without issue and then yesterday I booted up the VM and I could not access the outside work from within my VM. As far as the VM was concerned everything seemed fine, it had an IP address in the expected range there was just no connectivity. I needed to do some work in a Debian based machine so just quickly stood up a new VM, this time Debian Buster. As before it worked fine. However this morning I booted up the VM and encountered the same problem. With this VM I had created a snapshot shortly after standing it up when i knew it was working, so I reverted the machine to the snapshot and again I had no connectivity within the VM. I then tried VirtualBox, I stood up a Debian Buster VM and booted into it, it worked fine. At some point later network operations stopped working like with VMWare. Any idea what could cause networking to stop working within my VMs? Cheers Adam

I want to map my Fn key to work on LXDE environment.
by Cătălin George Feștilă 14 Feb '21

14 Feb '21

The Fn key is the wakeup key when the machine is suspended. If anyone wants to map it to other functions, then that's okay. I want to map the Fn key on Fedora 33 LXDE. My keyboard hardware come with an Fn key, see: [img]https://i.imgur.com/HJlpSEt.jpg[/img] These are the infos about my Linux and hardware: $xmodmap -pke | grep "=$" keycode 8 = keycode 93 = keycode 97 = keycode 103 = keycode 120 = keycode 132 = keycode 149 = keycode 154 = keycode 168 = keycode 178 = keycode 183 = keycode 184 = keycode 197 = keycode 202 = keycode 217 = keycode 219 = keycode 222 = keycode 230 = keycode 247 = keycode 248 = keycode 249 = keycode 250 = keycode 252 = keycode 253 = The Fn key is disable because I don't have a response from xev command: $ xev The GRUB starts with: $ cat /etc/default/grub GRUB_TIMEOUT=5 GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)" GRUB_DEFAULT=saved GRUB_DISABLE_SUBMENU=true GRUB_TERMINAL_OUTPUT="console" GRUB_CMDLINE_LINUX="resume=/dev/mapper/fedora-swap rd.lvm.lv=fedora/root rd.lvm.lv=fedora/swap rhgb quiet splash acpi_osi=Linux selinux=1 enforcing=1 GRUB_DISABLE_RECOVERY="true" GRUB_ENABLE_BLSCFG=true

Verifying a Fedora-33 Image
by Jonathan Ryshpan 11 Feb '21

11 Feb '21

I have downloaded the Fedora-33 KDE spin and am attempting to verify it. Following the instructions (appended below for convenience) I have: * Imported the keys using curl (where do they go?) and * Verified the CHECKSUM file using gpg The verification fails with this message: $ gpg --verify-files *-CHECKSUM gpg: Signature made Fri 23 Oct 2020 08:09:07 AM PDT gpg: using RSA key 963A2BEB02009608FE67EA4249FD77499570FF31 gpg: Good signature from "Fedora (33) <fedora-33-primary(a)fedoraproject.org>" [unknown] gpg: WARNING: This key is not certified with a trusted signature! gpg: There is no indication that the signature belongs to the owner. Primary key fingerprint: 963A 2BEB 0200 9608 FE67 EA42 49FD 7749 9570 FF31 This doesn't look good. How can I verify the CHECKSUM file? Verification instructions from https://spins.fedoraproject.org/en/verify follow: Next, import Fedora's GPG key(s): $ curl https://getfedora.org/static/fedora.gpg | gpg --import You can verify the details of the GPG key(s) here. Now, verify that the CHECKSUM file is valid: $ gpg --verify-files *-CHECKSUM The CHECKSUM file should have a good signature from one of the following keys: - 12C944D0 - Fedora 32 - 3C3359C4 - Fedora 31 - CFC659B9 - Fedora 30 - DBBDCF7C - IOT 2019 Finally, now that the CHECKSUM file has been verified, check that the image's checksum matches: $ sha256sum -c *-CHECKSUM If the output states that the file is valid, then it's ready to use!

Fedora 33 and HDMI KVM switch
by Paolo Galtieri 09 Feb '21

09 Feb '21

Folks, I'm having an issue running Fedora 33 and an external monitor connected to an HDMI KVM switch. Here is the way it's connected: Laptop thunderbolt 3 connector -> 4 port USB c to USB 3.0 hub -> USB to HDMI adapter -> HDMI KVM switch. The mouse and keyboard work, however Fedora 33 does not detect the external monitor. Even if I take the KVM switch out of the equation Fedora 33 still does not find the external monitor. This laptop also boots to Windows 10 and everything works fine there. I have an older laptop running Fedora 31 connected as follows: laptop HDMI port -> HDMI KVM switch. This works fine. Any help is appreciated. The KVM switch is a 4 port AV Access HDMI 2.0 KVM Switch Paolo

Can't reliably right click with mouse due to click interval... F33 Workstation, Plasma,
by linux guy 09 Feb '21

09 Feb '21

I recently switched from a wireless USB mouse to a wired USB mouse. I cannot reliably right click links in Firefox because the click interval on the mouse isn't set up right. How does one modify the mouse click parameters in Fedora and/or Plasma ? I've looked in System->Settings but can't find anything for click intervals.

Preventing display manager running on gpgpu
by Neal Becker 09 Feb '21

09 Feb '21

After re-installing f33 following a disk crash, I was having problems that I believe were caused by nouveau trying to run on my gpgpu nvidia 2080 ti. I don't need or want a display manager running on it. How can I tell if wayland and/or X is configured to run on that card, and how can I disable it for that card? I also have a built-in vga that runs a display. Thanks, Neal
