|
|
|
|
|
Automatically assign a dedicated systemd scope to the GUI applications
|
|
|
|
|
launched in the same cgroup as the compositor. This could be helpful for
|
|
|
|
|
implementing cgroup-based resource management and would be necessary when
|
|
|
|
|
`systemd-oomd` is in use.
|
|
|
|
|
|
|
|
|
|
Limitations: The script is using i3ipc window:new event to detect application
|
|
|
|
|
launches and would fail to detect background apps or special surfaces.
|
|
|
|
|
Therefore it's recommended to supplement the script with use of systemd user
|
|
|
|
|
services for such background apps.
