[SOLVED] Why do closed nvidia graphic drivers consume so much RAM?

I'm using nvidia Geforce 7600GT graphic card, and I tried to install nvidia-304xx graphic drivers. Everything went smoothly, but after my system started I saw that there is 4x times more RAM consumption when compared it to nouveau driver. See the following pics:

I've been trying to solve this issue for 2 weeks, but I have no idea why my system consumes almost 400 MiB of RAM when only openbox is started. Compared to debian + full gnome -- 280MiB. Both systems are using the same nvidia driver. I tried even to borrow the kernel from debian and then install the drivers, but this doesn't help. Still apps in the graphic environment consume several times more RAM.

As you can see, having only 1GiB of RAM I can't afford to have 400MiB openbox. Try to think about opening web browser or other apps. xD

Does anyone know why this is happening and how to fix it? I saw similar thread on this forum, but I can't find it anymore, and there was exactly the same situation, or more or less.

  1. According to your data openbox uses about 3.3 MiB independent of the graphics driver.

  2. There's a lot more running than just openbox (conky, terminator, some applet things).

Compared to debian + full gnome -- 280MiB.

Debian is old, and debian's gnome is old, too, so you propably won't gain much from comparing debian and arch (debian+nouveau vs. debian+closed drivers might be interesting though).

For better insight -- data from http://www.pixelbeat.org/scripts/ps_mem.py

Examine your data, find out who's eating away your RAM and try to fix/replace/drop the bad guys.

Re: [SOLVED] Why do closed nvidia graphic drivers consume so much RAM?

I'd say the nvidia kernel module is just bigger and it is loaded. If you do "lsmod" it has the biggest "Size" by far compared to other kernel modules.

Re: [SOLVED] Why do closed nvidia graphic drivers consume so much RAM?

cookies, look at the ps_mem.py log:
7.4 MiB    conky (3)   -- nouveau
vs
70.8 MiB    conky (3)  -- nvidia

Compared it to debian:

morfik:~$ lsmod | grep nvidia
nvidia              10224976  40
morfik:~$ nvidia-settings --version

nvidia-settings:  version 304.88  (buildd@murphy)  Wed Apr  3 09:32:37 UTC 2013
  The NVIDIA X Server Settings tool.

  This program is used to configure the NVIDIA Linux graphics driver.
  For more detail, please see the nvidia-settings(1) man page.
morfik:~$ uname -a
Linux morfikownia 3.8-10.slh.2-aptosid-686 #1 SMP PREEMPT Sat Apr 27 16:10:35 UTC 2013 i686 GNU/Linux
morfik:~$ ps -eo "%mem user args" | grep conky
 0.5 morfik   conky -c /home/morfik/.conky/.conkyrc
 0.5 morfik   conky -c /home/morfik/.conky/.conkyrc_fs
 0.5 morfik   conky -c /home/morfik/.conky/1b1/.conkyrc_1b1_int
 0.5 morfik   conky -p 5 -c /home/morfik/.conky/1c/.conkyrc_1c

I couldn't start the ps_mem.py script on debian, so that's why I used ps.

I have 1 GiB of RAM, so 0.5 means 5MiB, so even here, 4x 5MiB = 20MiB, not 70.8 MiB

I changed only the graphic driver and the consumption of RAM of my openbox (+apps)  went from 107.2 MiB to 359.9 MiB. So, how can I replace anything? Nvidia drivers consume 250MiB. big_smile

Compile cairo without gl support should fix this.

Re: [SOLVED] Why do closed nvidia graphic drivers consume so much RAM?

Vorbis, you're my savior! It works.
I changed some stuff since then, but I had 90 MiB graphic environment (nouveau). Now I have 129.0 MiB (nvidia) -- it's 40 MiB more, but I can live with that. smile And of course, it is not 300+ MiB.

I commented out the following lines:

I couldn't compile cairo with --enable-egl , so that's why I removed it too.
