I wanted to know what i did wrong with my picom configuration file. I'm currently using Arch Linux - 5.6.10 with i3-gaps as WM and Picom as a compositor.

Error message:

[ 08/05/20 13:43:36.014 init_render WARN ] Old backends only support blur method "kernel". Your blur setting will not be applied

Can someone please tell me what does that mean?

The reason for this error is probably because you have used gaussian blur or box blur in your picom config file. These are only supported by experimental backends as of now.

Use picom --experimental-backends to run picom and you should be able to get the blur effect. It is recommended you use picom --experimental-backends --backend glx as performance is better with glx.

Alternatively, you could use kernel blur. In that case, you should specify which kernel to use. Refer to the BLUR section of the man page of picom for more information.

  • what a brilliant solution my man! Thanks, `picom -b --experimental-backends --backend glx` works like a charm. – hp77 Jun 11 '22 at 08:57
