Re: [i3] window assigned workspace and high cpu usage
Hi all again,
In order to add some more information about what happens when I start
emacs and I don't change to its assigned workspace, an 'strace -p `pidof
emacs`' repeats and repeats this kind of output:
---

And the output of 'ls -l /proc/`pidof emacs`/fd/8' is:
/proc/`pidof emacs`/fd/8 -> socket:[119884]
For fd=5,11 it also says socket:[something] and fd=7 says
anon_inode:[eventfd]

OK, tried this and it doesn't work neither. In my custom .xsession, at the end I call i3 like this: dbus-launch --exit-with-session i3 I will continue trying to discover what is happening here. Thanks for your comments and help and also thanks to Michael for this marvelous window manager. Antonio.
Re: [i3] window assigned workspace and high cpu usage
As soon as I arrive home I'll try Michael's suggestion and see what happens. I start i3 from my custom .xsession. I'll post it later as now I'm not on the computer.

Re: [i3] window assigned workspace and high cpu usage
I cannot reproduce this as well. # i3 version 4.10.2 (2015-04-16, branch "4.10.2") ... # Chromium 42.0.2311.90 # xorg-server 1.17.1-5 I used the config Antonio Corbi posted: bindsym $mod+Shift+m exec "chromium" assign [class="Chromium"] 2 Chromium opens with normal CPU usage and the workspace changes to the right color. After finished starting up CPU usage of chromium is as low as starting it "normal". Do you use i3 inside of a desktop enviroment? Maby that could help to repoduce it and locate the error?

Re: [i3] window assigned workspace and high cpu usage
It could be that the application in question is busylooping until it receives the MapNotify event. Perhaps for_window [class="Emacs"] move to workspace 2, workspace 2, workspace back_and_forth works? (but it will flicker) If so, file a bug upstream with the application(s) in question. On Mon, Apr 27, 2015 at 7:48 PM, Antonio-M.

Re: [i3] window assigned workspace and high cpu usage
I can't reproduce the CPU load with Google Chrome. However, it seems that if I wait a little before switching to the workspace, AdBlock dies. Makes me wonder if this is at all related. Do you have a log file? Ingo On 04/27/2015 07:48 PM, Antonio-M.
