multiple Xorg processes after launching emacs

Hi,
I have a problem that recently appeared and which involves Xorg and emacs. When emacs starts, it creates extra Xorg processes which are consuming a lot of cpu (see
htop ouput)

This is not systematic : some emacs instances do not create any such problem. I see no reason for this. Does someone do ?
Just in case that would matter, emacs is launched as a systemd unit (see https://wiki.archlinux.org/index.php/Em … stemd_unit and the unit file is

~/.config/systemd/user/emacs.service
[Unit]
Description=Emacs: the extensible, self-documenting text editor

[Service]
Type=forking
ExecStart=/usr/bin/emacs --daemon
ExecStop=/usr/bin/emacsclient --eval "(kill-emacs)"
Restart=always

[Install]

Re: multiple Xorg processes after launching emacs

Those aren't processes, those are seperate threads (X itself would prevent X from accessing the same display anyway)

https://unix.stackexchange.com/question … ss-than-ps

As for why Xorg uses so much CPU, what are you doing in your emacs instances, if those are what cause the load? Do you have hardware acceleration enabled?

Re: multiple Xorg processes after launching emacs

Emacs is my default editor

$ echo $EDITOR
emacs --daemon

It is also configured as the editor in many application config files (mutt, yaourt, ...). I also launch emacs manually. I know it can do so many things, but my exclusive use of emacs is for text typing (mail, latex, coding)

The Xorg issue is undoubtedly triggered by emacs launches. It looks like a random event: it will eventually appear at some time during my working session, but I can't relate it to some specific uses of emacs.

Do you have hardware acceleration enabled?

I'm not sure to understand what this actually means. I have libva-intel-driver installed and vainfo returns

Re: multiple Xorg processes after launching emacs

There's a bumblebee config, vainfo says "Intel i965 driver for Intel(R) Sandybridge Mobile" and yet the server loads the nvidia blob exclusively.
Is this a wayland session with an attempt to use the other chip on xwayland?

Re: multiple Xorg processes after launching emacs

My apologies! I picked the most recent xorg log file in my last post, which is Xorg.8.log, created and owned by bumblebee. So I guess it is quite normal that it shows no intel driver. The Xorg.0.log is

Re: multiple Xorg processes after launching emacs

Ok thanks, however the cause is more likely a race between emacs and your WM on the size of the emacs window.
(Hey, I didn't ask for HW acceleration ;-)

Thus
a) which WM
b) can you make emacs spike Xorg w/o any WM?
c) try xev -id <wid of emacs window> and see whether there's some event flood

Re: multiple Xorg processes after launching emacs

Well i was going more along the lines of mesa and  OpenGL and friends when I mentioned hardware acceleration.  Also something to try, is simply using the modesetting driver, I wouldn't put it past xf86-video-intel to mess something up here.

a) openbox 3.6.1-3
b) I dont know if this is correct: I have X running on display :0. I change to tty2 and login (no X) and then run 

sudo xinit emacs $* -- :3

and right after, I have the 4 Xorg threads appearing in the table of processes, but without such high CPU values. Starting xterm in the same way (instead of emacs) does not show the extra Xorg threads.
c)

That's no very good information, but I get ColormapNotify and ConfigureNotify events on focus change *only* - emacs should not create any events if you leave it alone (focused or not) and PropertyNotify events when typing.
If emacs is in a race about its size, you'll get tons of ConfigureNotify events. Tons of ColormapNotify events seem like a bug in emacs that is maybe triggered by some specific feature (I don't use emacs, I chose Linux as my OS ;-P )

Yes that's what I mean, remove xf86-video-intel it really likes to break in all sorts of interesting ways. Xorg has a built in modesetting DDX and xf86-video-intel has been pretty much ditched in favor for it, there haven't been any real changes in 3 years. And the few changes that make it in seem prone to breakage

Apologies once again. The xev output comes from moving the mouse and clicking around. Inactive emacs window does not output anything

I have nvidia and nvidia-utils uninstalled, blumbebeed stoped and disabled, just relying on xf86-video-intel+mesa. I'm still having the emacs-xorg problem

Yes that's what I mean, remove xf86-video-intel it really likes to break in all sorts of interesting ways. Xorg has a built in modesetting DDX and xf86-video-intel has been pretty much ditched in favor for it, there haven't been any real changes in 3 years. And the few changes that make it in seem prone to breakage

That must be something else. I also removed (uninstalled) the xf86-video-intel driver. That way I think I only use the Xorg built in driver. Now with no active window, Xorg uses more than 50-60% of the CPU

Re: multiple Xorg processes after launching emacs

Now with no active window, Xorg uses more than 50-60% of the CPU

"No active" means "no visible" or just "no focused"?
Are you absolutely sure this is related to emacs?
Do you always get several X11 threads when running emacs?
Did you try a non-rootless X server?
