Failing to run on Arch Linux

Tried the nightly release and the stable release, the same problem failing to start. Kernel version 5.7.7-arch1-1

Hi Maybe it's the same problem as the following. https://github.com/akiyosi/goneovim/issues/140#issuecomment-656947741

The solution is like the following

cd /path/to/goneovim && chmod u+x QtWebEngineProcess

[akiyosi]

Thanks for quick reply :) One more thing.

Could this problem be reproduced in /path/to/goneovim -u NONE?

[abdalazizrashid]

Yes, same behaviour. Any idea about the problem?

[abdalazizrashid]

Yeah, sure.

[akiyosi]

Umm, I can't reproduced it in my archlinux (5.3.10-arch-1). Is it because the version of archlinux is old...?

[abdalazizrashid]

Maybe, I'm not really sure. Try to update?

[akiyosi]

I'm going to try to update archlinux. Could you remove the setting.toml file and see if it reproduces?

[abdalazizrashid]

Hm, nothing changed the exact same behaviour!

[abdalazizrashid]

Any news?

[akiyosi]

What is your desktop environment? (KDE, GNOME, MATE, or somthing)

[abdalazizrashid]

I3

[akiyosi]

Hi, sorry for late. I've tried to create an environment close to yours, but I can't reproduce the probrem that causes CPU high load.

Are there any other applications that are specific to your environment?

[abdalazizrashid]

Well, nothing special :confused:

[abdalazizrashid]

What about we schedule an online meeting so I can share my screen and do live debugging?

[akiyosi]

I'm working on this repository in between jobs, so live debugging is difficult.

Is it possible to setup a goneovim development environment in your PC and use a debugger such as delve to pick up any potentially problematic processes?

The following pages describe the basic setup instructions.

https://github.com/akiyosi/goneovim/wiki/Development

If you have any detailed questions, you can ask us in the chat room and we can answer them.

[akiyosi]

Hi I appreciate your research.

I see; Goneovim determines the number of rows and columns based on the size of the minimap widget and the font size, but for some reason the font width and height seem to be zero.

In any case, I'll fix it, as it's not good code that can be divided by zero.

[p00f]

@akiyosi Just jumping in, I can use the GitHub Actions build from the refactor branch right?

[akiyosi]

@p00f Yes, you can use the build

[akiyosi]

BTW, this issue is related to the font issue in arch linux. I wonder if arch linux doesn't have "monospace" font by default. Umm.

[p00f]

I'm not sure what you mean. When you install a DE, you have to compulsorily install one of gnu-free-fonts, ttf-dejavu, or ttf-liberation

All the three have monospace variants included.

As in @abdalazizrashid 's case, I don't know about i3. (sorry for tagging you twice :P)

[p00f]

Actually I have two possible explanations: 1) Atleast in GNOME, Qt apps don't recognise certain fonts as monospace. This happened to me in nvim-qt, Konsole and Qterminal. 2) I remember redditors in r/archlinux posting about missing fonts when they use only WMs (i3 etc) so it is possible that @abdalazizrashid doesn't have monospace fonts at all. (Very unlikely)

[abdalazizrashid]

Thanks for the suggestions. I have many monospace fonts actually... So, I tried the patched version #143 the GUI still take a couple of minutes to load with full CPU load, but this time the GUI loads successfully with a message on the console: nvim:nvim_ui_attach validation: Expected width > 0 and height > 0 and It seems that this is the source of the https://github.com/neovim/neovim/blob/master/src/nvim/api/ui.c#L104. Also, I can't type anything in the editor I also tried it in dwm window manager, with the same behaviour.

[p00f]

okay, just to be sure, can you try it in a DE? like gnome or kde

[p00f]
