xorg.conf - RAM

[Ant2ne]

what is the line I need to put in my xorg.conf (and exactly where do I add it) to force my graphics card to grab 256 MB of RAM from my System RAM instead of the 128MB it is grabbing now. On my old hard drive I had it set up that way. But since the clumsy wife and the coffee incident I had to reinstall everything.

Sure, blame it on the Missus!



Actually, it depends on your video driver, apparently. If you use the dpkg-reconfigure xserver-xorg script, there's a screen where you enter the video RAM. But I checked my xorg.conf which was generated by the Nvidia driver, and there's nothing in it reflecting the 256M of RAM that it has. So, I guess the answer is "it depends".

I once "sudo kate xorg.conf" and edited this line from 128 to 256. It then used that much ram. I can't remember what I edited though.

Ant2ne do you have an integrated video? So only in bios you could set how many memory your system could to grab for frame buffer.

Grr... I know I've seen that setting before, and modified it in xorg.conf. Perhaps the modification didn't actually do anything other than change the displayed RAM usage.

UPDATE:
I Checked in my bios. There is no location to change my integrated video RAM. It has listed only the 8MB that is on the card.

I replaced my xorg.conf with a back up (from a few weeks ago) and my RAM is back up to 256. [verified by the display in System Settings->Monitor and Display->Hardware->Configure->"Choose Graphics Card WIndow"]

There is no RAM or 256 in my xorg.conf, so I still don't know how I did it before. Oh well at least my graphics is back up. :P

Re: xorg.conf - RAM

If you saved the low memory xorg.conf all you need to do is run the konsole command:

diff /etc/X11/xorg.conf /etc/X11/xorg.conf.lowmem

where you will have to substitute the actual name of the offending file.
