Ubuntu 12.04 Too many processes ?

[easysid]

Hi,
I installed Precise on my laptop a few days ago. A thing that caught my attentions was the number of processes and the amount of ram being used when the desktop first appears.

$ ps -e | grep -c '^'
170

$ free -m

     total       used       free     shared    buffers     cached
Mem:  2929      1316        1612          0      119        635

-/+ buffers/cache:562       2367

Swap:  1997          0       1997

Is this normal? 170 processes and 1.3 G Ram . I am not new to Linux, but I have been out of touch for past year or so. I noticed this only because I am new to Unity.

Thanx.

I haven't checked 12.04 since installing , but I have 157 on Unity 2D with opera running . If you want to see resource use for top processes use the following.

I am wondering what compiz is.

That sounds about right if you include the cache. Ubuntu 12.04 LTS is pretty heavy, as are many other modern interfaces like KDE and GNOME. If you want something lighter try Xubuntu or Lubuntu.

Compiz is a windowing manager that Unity uses. It's supposed to be there

Regarding processes, there's isn't any difference in Unity/Unity 2d. Its same ~170.

Ok. That settles it then. I just needed to clear it. If its normal than its alright.
AFAIK xfce isn't light anymore. I used to run it over my LFS install and it was fine then. But I am not so sure about recent developments ( whatever one learns from blogs etc. )

Thanx for the responses. I'll mark this as solved.

Xfce isn't as light as it used to be but still light compared to Unity (default in Ubuntu now).

From your 'free -m' output you are only using 562MB not 1316MB.
