 Posted: Mon Jul 22, 2013 2:18 pm Post subject: Processes in X are niced? |
 |
|
Hi,
I just noticed that the processes I see after starting xdm (lightdm), all the processes I start from X are niced. If I open a terminal and type 'nice' it shows me 10, some processes are 5, others are 15.
Why does this happen? Can it be disabled?

Are you looking at the right value. Try this:
| Code: | | ps -eo pid,rtprio,nice,policy,ruser,rgroup,comm,args |
3rd column, named "NI", is the niceness.

Thanks, yeah I am. Niceness of mostly 10 for the X processes, a few at 5.

Actually, no, one at 5 which is the script that launches the window manager. Everything 'under' that seems to be at 10.
I've a feeling it's done by the kernel because I've spent hours looking elsewhere, it became one of those nights where you realise, too late, that you threw most of it away. We all know what that can be like.
But I found nothing. I also tried to turn off 'automatic process scheduling' in the kernel but that didn't seem to make a difference.

Well show the command and its output, otherwise I'll just assume this is a dream  |

I don't see the need to put my entire process tree in here, but here is a snippet:
| Code: | % ps axfo pid,stat,nice,args
5640 SLsl 0 /usr/sbin/lightdm
5665 Ss+ 0 \_ /usr/bin/X :0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch
5673 Sl 0 \_ lightdm --session-child 12 15
5767 Ss 0 \_ zsh - /home/anci/.xinitrc.zsh
5795 SN 5 \_ /bin/zsh /home/anci/.xmonad/bin/autostart.zsh
5835 SN 10 \_ /bin/zsh /home/anci/.xmonad/bin/autostart.zsh
5836 SNl 10 | \_ gnome-panel
5911 SN 10 \_ /home/anci/.xmonad/xmonad-x86_64-linux
6606 SNs 10 \_ /usr/bin/firefox
|
Neither /home/anci/.xinitrc.zsh and /home/anci/.xmonad/bin/autostart.zsh contain any nice command.

| Maybe xmonad does it. E17 does a similar thing by default. |
