Switching back and forth between chamfer and my current wm (which I need to do to properly configure it from a familiar environment) seems to crash chamfer.

To reproduce:

1. Start chamfer in tty2
2. chvt 1
3. chvt 2, then chamfer crashes with:

focus a000e AIGLX: Suspending AIGLX clients for VT switch 
[chamfer]: Error: failed to acquire a swap chain image

The plan is probably to make the window look, feel and behavior configurable from the python config. For this purpose, it would probably be a good idea to create a shader look that is in between the current frame shader and the shader called default (the frame shader is pretty opinionated for a default look imo). A window border is pretty much a necessity, but shadows, rounderd corners, and dashed border lines aren't. The ability to set the frame border color is pretty much standard for a wm, however, especially for differentiating between focused and unfocused windows (this is something e.g. i3 and bspwm allow/do by default). It would also be nice to disable some animations by default. In other words, a more basic shader, that people can build upon to their liking, is probably a good idea.

I tried to combine the default and frame shader into one myself, but this proved a little too difficult for someone unfamiliar with shaders and vulkan. I haven't tried super hard, but currently it's difficult to see where the code for a basic window border starts, and what is relevant to eyecandy as rounded corners and dashed lines.

I tried launching chamferwm from exec chamfer --config=/usr/share/chamfer/config/config.py --shader-path=/usr/share/chamfer/shaders/, but it just disconnects me from tty. I tried redirecting stdout to a file to see what happens, but there is only [chamferwm 2020-01-15 19:34:43] Loading config /usr/share/chamfer/config/config.py... No pulsectl module.
Also there is nothing in /var/log/Xorg.0.log
Launching without the compositor does the same.
Launching without exec gives Error: failed to connect to X server (I don't know if this is expected).
I installed on arch with the AUR package, I'm using prime offloading with nvidia and intel proprietary drivers.

If you need any more info just ask.

When I try to launch Steam, keyboard input works, but it won't recognize mouse clicks.

Does chamferWM support multi monitor? And if so, what variable would I use for my monitor config?

Thank you.

At some point after starting chamferwm, the character echoed in the terminal starts to lag one character behind what has been entered.

For example, if I enter "ab", only "a" is echoed until I enter "c" at which point I can see "ab". I then have to enter "space" before I can see "abc".

I require assistance :P

Hello, I'm trying to install chamfer from aur, but the installation fails on shaderc-git which throws error without message, just a failure occured in prepare(), nothing more.
Can you help me with installation? I can try to compile from meson, but how about deps for running after that?
Thanks for help.

If I launch chamferwm (with instructions from the README), for a few seconds I see a black screen and a mouse pointer that I can move around, and then it crashes me back to the tty. It doesn't seem like it will let me start any programs.
I can't see any errors in ~/.local/share/xorg/Xorg.0.log. Is there another place where errors are logged?

I installed chamerfwm from the AUR. Other specifics are that I'm running xf86-intel-video-git, xorg-server-git, and a vanilla, fully updated Arch.

It's probably a misconfiguration on my side, so my main question is where to look for errors.

Assuming the window border is controlled by:

self.borderWidth = (0.005,0.005);

..changing the number does not change the width of the border, which obscures the window controls (maximise, minimise, exit).

Hello,

Do you have any information on implementation of VK_EXT_image_drm_format_modifier
we use nvidia on linux width proprietary drivers.

thanks

I've just built chamferfm and have it working - couple of questions:

config.py mentions "Panels, docks etc. should be rendered with no decorations.", but a wbar dock I'm using has a 5mm thick black/yellow border all the way around it - should this happen? Is there a way to stop it?

I see that config.py look for psutil and pulsectl and that there is some code about battery percentage, etc, but nothing is displayed?

Is there a man page/wiki somewhere that explains the keybindings (how to launch apps, quit chamferfm, etc)?

I have managed to launch chamferWM with light DM, rather inconsistently, is there an available script to write to make the launch successful every time that you may know of?

It would be great to use just the vulkan compositor with other WMs, like people use compton in plasma or xfce. Compton itself was considering a vulkan backend but it still didnt fly. What you think, @jaelpark ?

Assuming the keystroke combo to start a browser is "alt 1", it does not work for me.

The other keystroke combo's I've tried do work - allowing for "alt shift e" not making it to the tty.

Hi
I try to compile the project on debian 10 and i have lot of error. do you have any idea ?

As titled. I got the exception thrown at line 492 in compositor.cpp while trying to start it up. It looks like it detected all the extensions except for VK_KHR_incremental_present.

(Also, as a suggestion, it is possible to also list which extensions chamfer is looking for before the listing of detected ones? Just so I don't need to go back to the code to figure out what was missing)

By "detected all the extensions" I mean, everything here except VK_KHR_incremental_present from line 467.

		VK_KHR_SWAPCHAIN_EXTENSION_NAME,
		VK_KHR_INCREMENTAL_PRESENT_EXTENSION_NAME,
		VK_KHR_EXTERNAL_MEMORY_EXTENSION_NAME,
		VK_EXT_EXTERNAL_MEMORY_HOST_EXTENSION_NAME,
		VK_KHR_EXTERNAL_MEMORY_FD_EXTENSION_NAME,
		VK_EXT_EXTERNAL_MEMORY_DMA_BUF_EXTENSION_NAME

I installed chamferWM via AUR.
When using the following command in xinit.rc:

exec chamfer --config=/usr/share/chamfer/config/config.py --shader-path=/usr/share/chamfer/shaders/

I only get a blank white screen.

I also tried:
exec stdbuf -oL chamfer --shader-path=/usr/share/chamfer/shaders/ > /tmp/log
but the log does not contain any errors

libxcb is installed of course... :(

Do we have to create these entities?

There are several such situations in your code.

I'm asking because I'm considering using chamferwm and I use sxhkd as a hotkey daemon and wmctrl to change workspaces and window focus, position and size.

When chamferwm is first started the cursor does not show.

I am obliged to move the mouse blind until it rolls over the wbar dock and the cursor appears, so I can launch an app.

If the app launches full screen, then the cursor remains for the rest of the session. If the app launches part screen, then the cursor is not visible over the background.

as title.
