Description doug 2000-07-19 17:50:35 UTC
I'm running an upgraded RedHat 6.2 system to get the
XFree86-4.0.1-30.i386.rpm to run.  I don't remember how many packages I had
to upgrade to get it working.  I have two graphics cards (matrox g400 sh,
guillemont riva tnt2 m64).  I am not using the nvidia custom drivers, just
the nvidia drivers in the rpm.  I am running in xinerama mode.  My kernel
is 2.2.16-3 from rpm.  I am also running enlightenment 16.4 from cvs.  What
happens is that after my X session has been running a while, X will start
churning.  It doesn't go into a "tight loop", but it does eat the cpu.  It
typically stays around 50% cpu usage according to 'top'.  The only solution
is to restart the X session.  Of course, everything else seems to run slow
when X gets into this state.

Does this persist with the latest X packages?

Comment 2 doug 2000-08-15 01:29:11 UTC
I will check and post results.  However, I upgraded my enlightenment to latest
cvs.  I still have problem, but it doesn't occur as frequently.  Please note
that 'top' reports that 'X' is eating up cpu.  Of course, enlightenment works
closely with X.

Comment 3 doug 2000-08-16 15:51:14 UTC
I am unable to upgrade to XFree86-4.0.1-0.43.i386.rpm because I only have
rpm-3.0.5-0.5 installed on my system.  I can't figure out how to upgrade to
rpm-4x without installing the beta RH7.0.

Comment 4 Bill Nottingham 2000-08-16 21:59:30 UTC
The -30 package was compiled by a compiler with
a bug that could cause strange X server behavior, that's
why I'm mentioning this.

You should be able to use the latest 3.0.5 RPM at
to install later X packages.

Comment 5 doug 2000-08-17 15:31:33 UTC
OK, I'm running XFree86-4.0.1-0.43 now.  I'll post in another day to report if I
see the same behaviour or not.

Comment 6 doug 2000-08-19 16:09:40 UTC
I cam in this morning and found X running at 47% CPU.  I leave X running for
several days.  This particular session has been up since Aug 17 (when I
installed the -0.43 packages).

I just glanced over at top and found that X was only at 15%.  I had an Eterm
running top covering an XEmacs window.  I thought, "maybe XEmacs is what is
causing the problem."  So, I exposed XEmacs and moved the window around with the
titlebar.  Of course, X cpu usage went up while I was dragging the window
around.  I actually got it as high as 80%.  Now I've been waiting for about five
minutes and X has been steady around 50%.

I'm not sure what this points to; maybe the window manager (Enlightenment cvs)? 
I will post to the enlightenment-devel mailing list and see what they think.

Comment 7 Bill Nottingham 2000-08-19 22:16:46 UTC
It does sound like an enlightenment problem; I haven't
heard any reports of this here with our enlightenment
packages, or with other window managers.
