Package: xserver-xorg-core

Running up-to-date Etch.

Over time, xorg takes up more and more memory.

I have two computers:
	rocky: PII-233 with 64 MB ram running i386
	titan: Athlon64 with 1 GB ram running amd64

On my i386, I only have 64 MB of ram so I can only run X for about 45
minutes before the system thrashes.  Eventually, Xorg dies but doesn't
release the screen.  If I let the system sit for about 60 minutes, the
thrashing subsides and I can ssh in and reboot to get my screen back.
Hard on the disk, but the i386 is only a client box.

On my amd64 Athlon64, I have 1 GB of ram so can run xorg; I haven't left
this computer run long enough to run out of memory and thrash since its
my main box; it gets turned off at night and through the day acts as a
server.  In the evening if I want to access the big screen, I'll run X
for a couple of hours.

This happens irrespective of window manager or DTE; on the i386 icewm
takes up less memory so Xorg will run longer before thrashing than if
I'm running xfce.  It also happens if I don't use a wm at all and just
run rxvt.

Tried the vesa xorg driver instead of the trident with no change.

Here's a concrete example of the problem.  This is run on my i386
(rocky) and titan is my main Athlon64 amd64 box.

rxvt and run nice top.  shrink so just watch the header info e.g. swap
ssh titan -f /usr/bin/kpdf
open a long file
view each page in turn

As each new page is viewed, xorg uses more memory, and swap goes up.

Its as if xorg is using memory to hold the image for the new page and
isn't releasing the memory used to hold the old page.  I conjuecture
that its holding all viewed pages in memory.

On the amd64, I have the xorg metapackage installed.  However, on the
i386 I am very tight on disk space so only have what's needed:


with everything on which they depend.  

xorg.conf is generated by debconf.  I added a virtual line but removing
that makes no difference.



here's my xorg.conf

Closing as earlier mentioned.

I cannot insert in a editor from Excel 4.7.6, how does it work?

You must disable a printer for booting the display.
