1Gbps Ethernet drops to 100Mbps
Hi all, I have a 1Gbps network port that correctly connects as 1Gbps full duplex on boot, then drops to 100Mbps 4 seconds later. Forcing 1Gbps full duplex with ethtool works fine. Tested to make sure the actual speed is over 100Mbps. I am trying to determine what causes the drop to 100Mbps and how to avoid it. The network port is on a Thunderbolt 3 hub in case this matters. Though it appears that it looks just like a regular 1Gbps card to igb driver. Tried two different Cat6 cables at 5 ft distance to the switch. There is nothing aside from loopback in /etc/network/interfaces and /etc/network/interfaces.d. Relevant log entries: # dmesg | grep -E '(igb|eth|enp9s0)' [1.707669] wmi_bus wmi_bus-PNP0C14:01: WQBC data block query control method not found [5.578360] igb: Intel(R) Gigabit Ethernet Network Driver - version 5.4.0-k [5.578360] igb: Copyright (c) 2007-2014 Intel Corporation.

When trying to share the screen a message comes up saying that screen sharing is only available in Gnome on Wayland on Debian 9+,, and screen sharing does not start. I am baffled by this. Did you install this from the flatpak?? Yes, flatpak from flathub.org. I don't think any kind of screen sharing works in Wayland. I am using X11. (KDE Plasma, but that's irrelevant.) There should be an option to switch to Gnome X11 when logging in. -- Nazar

If the choice is not yours though, there is a flatpak for it: https://flathub.org/apps/details/us.zoom.Zoom. It's kept isolated from your system and it works.

Perhaps with the help from the change proponents. I don't think it's an issue that'll be resolved in the direction you intend. It's the enforcement of a security model that has guided most of us for years: not running GUI applications as root. In all of history of UNIX and Linux, root means root. You know what you are doing and accept the risks. rm -rf /, vim or wget under root are dangerous too. And Wayland doesn't actually change that, since nothing can, root is still root. You can do: xhost +SI:localuser:root and run whatever you want as root. This is exactly what the latest gparted does [1]. So this "security model" boils down to an annoyance. [1] https://gitlab.gnome.org/GNOME/gparted/blob/master/gparted.in#L70 The normal way of circumventing this is to have a non-GUI program that performs all the work running as root, with a connection to a GUI client program that runs as the user/administrator. Yes, that is the Wayland way. And it's now Wayland way or no way for all, not just Wayland users. ... for synaptic, it might be written in such a way that you can get the resolver to run with your friendly interface as an ordinary user, and then use apt-get, say, to install the list of packages that synaptic has come up with. ... Or just wrap it with a shell script that adds/removes root with xhost like gparted does, unless somebody has a compelling desire to *implement* (as opposed to force someone else to implement) "Wayland way". I tested this and it works like a charm. These are the things that should be considered and resolved when making a breaking change (Wayland default). -- Nazar

How are you connecting to VPN? If it's with network-manager-openvpn it should automatically restore your DNS to a configuration prior to connecting VPN. Look in /etc/resolv.conf before, during and after VPN connection. After should be restored to the state before. If you are using something other then network-manager-openvpn, it should restore resolv.conf for you or you may need to manually script that. > I use network manager 1.12.2. -- Nazar
