I'm using MX Linux 23.2, my keyboard is Logitech K120 Spanish, during installation, I chose 104key-pc keyboard, but when trying to configure composite key to create accent char (such as á, à, ã, ç, etc.), it does not work, either the accent does not show up or only showed up after several tries, which keyboard should I choose with my keyboard to enable composite key?

I am on Arch using Xorg, lightdm, and Cinnamon. When I try to run Picom in Cinnamon I get:

~$ picom
[ 11/20/22 23:52:28.630 session_init FATAL ERROR ] Another composite manager is already running

I understand that there is another compositor running apparently, so I installed inxi to check, and when I run ~$ inxi -Gxx | grep compositor it returns nothing. I have used i3 with Picom on this same installation and it works flawlessly. I don't see why it's not working in Cinnamon. My question is, can I change the settings to give Picom override permissions over other compositors? If not, how should I solve this problem?

I am using Arch linux with i3wm and picom as compositor. I would like to be able to use redshift. But when I launch redshift, it turns itself on and off every two seconds, resulting in annoying screen blinking. What can I do to stop this blinking and use redshift in peace?

I've used many variants of Linux(mostly Debian derivatives) for over a decade now. One problem that I haven't seen solved satisfactorily is the issue of horizontal tearing, or Vsync not being properly implemented. I say this because I use used 5 different distros on 4 different computers with various monitors and Nvidia/AMD/ATI/Intel graphics cards; every time, there has been an issue with video tearing with even slight motion. This is a big problem, especially since even Windows XP doesn't have these issues on modern hardware. If anyone is going to use Linux for anything, why would they want constant defects to show up when doing anything non-CLI? I'm guessing that either few developers know about this problem or care enough to fix it. I've tried just about every compositor out there, and usually the best they can do is minimize the issue but not eliminate it. Shouldn't it be as simple as synchronizing with the refresh rate of the monitor? Is there some politics among the OSS community that's preventing anyone from committing code that fixes this? Every time I've asked for help on this issue in the past, it either gets treated as an edge case(which I find difficult to believe it is given the amount of times I've replicated the problem) or I get potential solutions that at most minimize the tearing.

I'm using Arch Linux, and have both Gnome and the i3 window manager installed. When running i3, I'm trying to initiate the composite manager Compton. But trying to do so results in the following error: $ compton [ 04/11/2019 22:32:36.443 register_cm FATAL ERROR ] Another composite manager is already running I think this means that Compton is already running, or Mutter is running, but I'm not sure which. **Is there a command I can use to determine which composite manager is currently running?**

I have a large directory tree with many sub-folders and lots of images within each one. I found a script that applies watermark to all images within a directory, in-place, overwriting the original image. I'm looking for the best way to iterate trough all the folders and subfolders and run the "compose" command for each image on my linux server. Here is the original script I found #!/bin/bash ########################################### # NAME: wn-ow # AUTHOR: Linerd (http://tuxtweaks.com) , Copyright 2009 # LICENSE: Creative Commons Attribution - Share Alike 3.0 http://creativecommons.org/licenses/by-sa/3.0/ # You are free to use and/or modify this script.

Is there anyway to do a composite video setup where the webcam is overlain onto the desktop and output as a video device (simulated webcam)?

I am developing a uC device which enumerates as three virtual COMs (actually it is a composite device). Everything works perfect except one small thing. Those ports belong to the dialout group and can be accesses only if the user has the root privileges or belongs to this group. Is there any way of automatic rights or group change during the enumeration?

Is there any composite manager to use with i3 except Compton. I am having serious tearing and ghosting. I have been using various Compton configuration none of which are working. So if there is a composite manager which I can use with i3wm or if there is a workaround this please let me know.

xcompmgr provides the following option: -s Server-side compositing with hard-edged shadows. From experimentation, I can say that this is much, much faster than the "client side" options. But what exactly is it doing? In Xorg, what is the difference between client- and server-side compositing? And, more to the point: what set of Xorg functions would I have to use, if I wanted to implement server-side compositing in e.g. a window manager?

How can i disable compositing via the command line? I need to disable temporarily for some games, like Nexuiz, for use in a wrapper script to toggle compositing status.

How can I add smooth scrolling between tags in the Awesome WM? I realize I can't run compiz with Awesome. Is there something comparable that I can run? I don't need any other effects, switching between tags quickly is just disoreinting when it jumps as it does. EDIT: While I didn't find an exact answer, cairo-compmgr gives smooth fading between tags and clients. I'm satisfied :)

Will we still be able to use Compiz?

In order for me to watch HD videos without tearing, I need to disable my Composite setting in xorg.conf Section "Extensions" Option "Composite" "Disable" EndSection But I love my transparency, so, how do I enable and disable it without restarting X? (Preferably using command line)
