How to run Chrome/Firefox on one machine, display on another machine

[kierun (Dr Yann Golanski)]

I have a weird problem…

I have a desktop and a laptop. I need to run Chrome (or Firefox or Chromium, I do not care which) on the laptop but send the display to the desktop. Why? Don’t ask… It’ll take too long to explain.

• I can do that with X11 forwarding with ssh, but the latency is too horrid to be useable.
• I can use w3m via ssh or another console browser. However, this is not really practical for what I need to do.
• Remote desktop, like VNC is overkill. I don’t want a full desktop, just a web browser.

Is there anything like that I can use?

[kierun (Dr Yann Golanski)]

I just tried x2go which gives me this:

Access denied for 'unknown'. Authentication that can continue: publickey,keyboard-interactive
Access denied for 'unknown'. Authentication that can continue: publickey,keyboard-interactive

Whether I use Internet broswer or gnome or anything else, I get this.

I know ssh works fine.

[kierun (Dr Yann Golanski)]

This looks perfect…

Sadly, I am using X11 (due to awesome window manager) on the desktop. Dammit! Maybe a reason to move to i3 or hyprland.

PS: Not sure why my previous post was marked as abuse. ¯\_(ツ)_/¯

@steppybug

Are you able to install waypipe on both machines?

waypipe ssh username@hostname firefox --new-instance

I see someone marked this as solution. Does this mean that waypipe over ssh is more performant than X forwarding over ssh in your case? Do you use that with a wayland session is window mode within X11? The OP said they have to use X11.

@steppybug

How did the reply get marked as a solution?

Probably the OP marked it, which seems reasonable after reading his post following.

[mjg (Michael J Gruber)]

@steppybug

I also do not consider waypipe a solution after the OP response. How did the reply get marked as a solution? Is there a place to go to learn more about fedora help request lifecycle?

The waypipe performance is in question. There are plenty of options to waypipe to try out. I also wonder if fewer pixels and more commands are used compared to X11 forwarding. If VNC is overkill then it is at least a potentially performant enough solution except for the X11 requirement.

I didn’t mean to criticize the marking. I was wondering about different performance of waypipe compared to X forwarding - which is not unlikely due to the different architecture, and how this works between X and Wayland (possibly Xwayland).

[kierun (Dr Yann Golanski)]

Very simple: there are no other answers, and the current one does offer a solution. It’s not ideal, as I would need to change window manager. However, it is better than nothing.

If anyone has a solution with X11, great.

[kierun (Dr Yann Golanski)]

I just tried, and this is what I get:

waypipe ssh yg@berserk xterm

Both machines running Gnome on Wayland (checked via loginctl show-session 2 -p Type) and export XDG_RUNTIME_DIR=~/xdg-wayland set in both ~/.bashrc and ~/.zshrc.

What am I doing wrong?

[gnwiii (George N. White III)]

Both Fedora and Debian have XDG_RUNTIME_DIR =/run/user/NNNN “automagically” configured, with permissions:

% ls -ldZ $XDG_RUNTIME_DIR
drwx------. 4 $USER $USER unconfined_u:object_r:user_tmp_t:s0 120 Oct 10 07:38 /run/user/NNNN/

[kierun (Dr Yann Golanski)]

On the desktop, I am seeing this:

I do get a pop up asking for my SSH passpharse.

[gnwiii (George N. White III)]

If you are still using Xorg, ssh -AY <host> firefox --new-instance “works for me”.

If you switched to a Wayland WM waypipe ssh <host> alacritty “works for me” in a Wayland session using waypipe. For both systems, ls -al $XDG_RUNTIME_DIR/Alacritty* shows entries like:

srwxr-xr-x. 1 <user> <group> 0 Oct 10 15:49 /run/user/1000/Alacritty-wayland-qfxJk2vx-4660.sock=

[glb (Gregory Lee Bartholomew)]

x2go should have worked and it is much more performant than X11 forwarding over SSH. Unless your username is “unknown”, it looks like you just didn’t complete the connection profile correctly.

I had that session configured for normal password authentication. But I know that X2Go does work with 2FA.

Edit: I do note that x2goclient errors out if the environment variable QT_QPA_PLATFORM is not set to xcb (i.e. env QT_QPA_PLATFORM=xcb x2goclient). I don’t know if that is normally required or if it is something peculiar to my configuration. I got that command from inspecting /usr/share/applications/x2goclient.desktop.
