debian-5.0.3 on ThinkPad A21e : dude, where's my RAM ?
Hi all,
I've just installed a fresh debian on an old IBM ThinkPad A21e (see cpuz info in attachement) and I'm kinda bedazzled - in the wrong sense! - at how much an idle system seems to hog RAM : out of 256, half of it is always used... I've tried a default Ubuntu and Xubuntu install, but browsing the Internet was a sluggish nightmare, that is why I've decided to give it a go with debian, installing the base system and laptop pack only (added openssh-server after reboot). I'll attach a stripped log about memory info, if anybody as any ideas or hints about what's going on it would be really appreciated!

If the system is idle than you don't really need the RAM, don't you? Watch the swap usage, because it's a better indicator.

It is used as a cache for files from the hard disk. The services running on the system take only 17 Megabyte, as can be seen in the third line of the "free" output: > frosties:~# free > total used free shared buffers cached > Mem: 256396 125280 131116 0 7908 99752 > -/+ buffers/cache: 17620 238776 > Swap: 369452 0 369452 This is absolutely fine.

Thanks for your inputs, I'll proceed with Xfce installation for now... if I end up with another choking slug, I'll come back to haunt you! :o)

Xfce - or any other light wm (windowmaker, lxde, enlightenment) - is better for such a laptop than gnome (good luck uninstalling it). >From my free -m i get this: total used free shared buffers cached Mem: 3934 3755 179 0 191 1703 -/+ buffers/cache: 1859 2074 Swap: 1906 50 1855 I doubt my computer's actually using almost 2GB (those 1859), and this number is high because i have a whole bunch of stuff open[1] plus services and daemons[2].

You can see memory usage in `top`; press "<" 3 times to sort on "RES" (RESident memory). -- __________________________________________________ __________________ TonyN.:' <mailto:tonynelson@georgeanelson.com> ' <http://www.georgeanelson.com/> -- To UNSUBSCRIBE, email to debian-user-REQUEST@lists.debian.org with a subject of "unsubscribe".
