# Compton

__Compton__ is a compositor for X, and a fork of __xcompmgr-dana__.
|
|
|
|
I was frustrated by the low amount of standalone lightweight compositors.
|
|
Compton was forked from Dana Jansens' fork of xcompmgr and refactored. I fixed
|
|
whatever bug I found, and added features I wanted. Things seem stable, but don't
|
|
quote me on it. I will most likely be actively working on this until I get the
|
|
features I want. This is also a learning experience for me. That is, I'm
|
|
partially doing this out of a desire to learn Xlib.
|
|
|
|
## Changes from xcompmgr:
|
|
|
|
* OpenGL backend (`--backend glx`), in addition to the old X Render backend.
|
|
* Inactive window transparency (`-i`) / dimming (`--inactive-dim`).
|
|
* Titlebar/frame transparency (`-e`).
|
|
* Menu transparency (`-m`, thanks to Dana).
|
|
* shadows are now enabled for argb windows, e.g. terminals with transparency
|
|
* removed serverside shadows (and simple compositing) to clean the code,
|
|
the only option that remains is clientside shadows
|
|
* configuration files (see the man page for more details)
|
|
* colored shadows (`--shadow-[red/green/blue]`)
|
|
* a new fade system
|
|
* VSync support (not always working)
|
|
* Blur of background of transparent windows, window color inversion (bad in performance)
|
|
* Some more options...
|
|
|
|
## Fixes from the original xcompmgr:
|
|
|
|
* fixed a segfault when opening certain window types
|
|
* fixed a memory leak caused by not freeing up shadows (from the freedesktop
|
|
repo)
|
|
* fixed the conflict with chromium and similar windows
|
|
* [many more](https://github.com/chjj/compton/issues)

### How to build
|
|
|
|
To build, make sure you have the dependencies above:
|
|
|
|
```bash
|
|
# Make the main program
|
|
$ make
|
|
# Make the man pages
|
|
$ make docs
|
|
# Install
|
|
$ make install
|
|
```
|
|
|
|
(Compton does include a `_CMakeLists.txt` in the tree, but we haven't decided whether we should switch to CMake yet. The `Makefile` is fully usable right now.)
|
|
|
|
## Known issues
|
|
|
|
* Our [FAQ](https://github.com/chjj/compton/wiki/faq) covers some known issues.
|
|
|
|
* VSync does not work too well. You may check the [VSync Guide](https://github.com/chjj/compton/wiki/vsync-guide) for how to get (possibly) better effects.
|
|
|
|
* If `--unredir-if-possible` is enabled, when compton redirects/unredirects windows, the screen may flicker. Using `--paint-on-overlay` minimizes the problem from my observation, yet I do not know if there's a cure.
|
|
|
|
* compton may not track focus correctly in all situations. The focus tracking code is experimental. `--use-ewmh-active-win` might be helpful.
|
|
|
|
* The performance of blur under X Render backend might be pretty bad. OpenGL backend could be faster.
|
|
|
|
* With `--blur-background` you may sometimes see weird lines around damaged area. `--resize-damage YOUR_BLUR_RADIUS` might be helpful in the case.
|
|
|
|
## Usage
|
|
|
|
Please refer to the Asciidoc man pages (`man/compton.1.asciidoc` & `man/compton-trans.1.asciidoc`) for more details and examples.
|
|
|
|
Note a sample configuration file `compton.sample.conf` is included in the repository.
|
|
|
|
## Support

|
|
* Bug reports and feature requests should go to the "Issues" section above.
|
|
|
|
* Our (semi?) official IRC channel is #compton on FreeNode.
|
|
|
|
* Some information is available on the wiki, including [FAQ](https://github.com/chjj/compton/wiki/faq), [VSync Guide](https://github.com/chjj/compton/wiki/vsync-guide), and [Performance Guide](https://github.com/chjj/compton/wiki/perf-guide).

## License
|
|
|
|
Although compton has kind of taken on a life of its own, it was originally
|
|
an xcompmgr fork. xcompmgr has gotten around. As far as I can tell, the lineage
|
|
for this particular tree is something like:
|
|
|
|
* Keith Packard (original author)
|
|
* Matthew Hawn
|
|
* ...
|
|
* Dana Jansens
|
|
* chjj and richardgv
|
|
|
|
Not counting the tens of people who forked it in between.
|
|
|
|
Compton is distributed under MIT license, as far as I (richardgv) know. See LICENSE for more info.
