Laundry List of RH 6.0 Problems or Hardware Blues
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

<P><STRONG>
Hi
</STRONG></P>
<P><STRONG>
I am hoping you will be able to help. I have various problems with
Redhat 6.0
</STRONG></P>
<P><STRONG>
A Current problem
</STRONG></P>
<P><STRONG>
1. Whilst running gnome 1.04 I can access no terminal windows except kde
terms.
</STRONG></P>
<P><STRONG>
Xterm window does not appear complaining about no ptys free
</STRONG></P>
<P><STRONG>
rxvt does not appear complaining about colour maps
</STRONG></P>
<P><STRONG>
Gnome-terminal appears but with no promt just a cursor which I cannot
type into.
</STRONG></P>
<BLOCKQUOTE><IMG SRC="../../gx/dennis/bbub.gif" ALT="(!)"
HEIGHT="28" WIDTH="50" BORDER="0"

Wow! That's pretty irritating.
</BLOCKQUOTE>
<BLOCKQUOTE>
The ptys problem suggests that your don't have the new
<TT>/dev/pts</TT> psuedo-filesystem mounted. <TT>/dev/pts</TT> is a virtual
filesystem (similar to <TT>/proc</TT>). It allows those programs
with the appropriate library support to dynamically allocate
ptys (psuedo-ttys, used by each xterm, telnet session,
'screen' window, etc).
</BLOCKQUOTE>
<BLOCKQUOTE>
My guess is that your other terminal emulators aren't
using that method, so they are searching through the list
of traditional ptys (<TT>/dev/ttyp*</TT>). It would be nice if the
programs that try to go through the pts system would fall
back to the old method automatically. (Of course I could be
wrong, perhaps it is the xterm that is using the old method,
and the others are getting they ptys dynamically. Look
under <TT>/dev</TT> for <tt>ttyp</tt>* and look at the mount command for a
<tt>/dev/pts</tt>.
</BLOCKQUOTE>
<BLOCKQUOTE>
The color maps problem suggests that the <A HREF="http://www.gnome.org/">GNOME</A>/Enlightenment
theme that you're using is taking up enough colors that
there aren't any available for your other applications.
If you're running Netscape Navigator/Communicator before you
try these commands, then it is the likely culprit --- it
steals a lot of colors.
</BLOCKQUOTE>
<BLOCKQUOTE>
You could try starting X with --bpp 16:
</BLOCKQUOTE>
<BLOCKQUOTE><BlockQuote><code>
startx -- :1 --bpp 16
</code></BlockQuote></BLOCKQUOTE>
<BLOCKQUOTE>
... (this is to put a 2nd X session on a new virtual
console, on the assumption that you are using a gdm, kdm, or
xdm graphical login on :0).
</BLOCKQUOTE>
<BLOCKQUOTE>
With 16 bits per pixel (if your video card and configuration
supports it) you should have lots more room in the color
map.
</BLOCKQUOTE>
<BLOCKQUOTE>
Another alternative is to change your X configuration and
disable your current list of startup applications (just
start with an xterm as the session manager, no window
managers, no xclocks or other widgets).
</BLOCKQUOTE>
<BLOCKQUOTE>
I have no idea what's wrong with your GNOME-terminal. It
could be suffering from the color map shortage as well.
Possibly it simply isn't communicating the problem as
gracefully as rvxt.

2. While checking rpms gnorpm dies when I try to access System
environment/ base (but only this category)
</STRONG></P>
<P><STRONG>
An xterm window sees to try to appear at this time.
</STRONG></P>
<BLOCKQUOTE><IMG SRC="../../gx/dennis/bbub.gif" ALT="(!)"
HEIGHT="28" WIDTH="50" BORDER="0"

This sounds like its related to the problem above.
</BLOCKQUOTE>
<BLOCKQUOTE>
(Personally I don't use any GnoRPM or Glint type front
ends to RPM. I just use the 'rpm' command).
</BLOCKQUOTE>
<P><STRONG><IMG SRC="../../gx/dennis/qbub.gif" ALT="(?)"
HEIGHT="28" WIDTH="50" BORDER="0"

I can access gnome via gdm most of the time and run all programs except
these I believe.. It could possibly be a problem to do with the gtk
libraries bu I am running out of ideas
</STRONG></P>
<BLOCKQUOTE><IMG SRC="../../gx/dennis/bbub.gif" ALT="(!)"

I don't thinks the libraries are the problem in your case.
Certainly you might want to download many of the 125 upgraded
packages from <A HREF="ftp://updates.redhat.com"
>ftp://updates.redhat.com</A>
</BLOCKQUOTE>
<BLOCKQUOTE>
That site is very busy and often full. So you may want to
go to a mirror site such as:

<BLOCKQUOTE><BlockQuote>

<p><em>[ You'd better stick with
<A href="ftp://ftp.cdrom.com/pub/linux/redhat/"
>ftp://ftp.cdrom.com/pub/linux/redhat/</A> and use
human judgement for the directories beyond that; they
keep changing the directory structure. -- Heather ]</em></p>
<BLOCKQUOTE>
There are at least seven GNOME related update packages
there.

B Recurring problem (which I think has caused the present problem.
</STRONG></P>
<P><STRONG>
regularly when rebooting e2fsck destrotys patrts of my file system. This
has appeared in various ways:
</STRONG></P>
<P><STRONG><BlockQuote>
moving directories into lost+found
deleting entiring directories
deleting/corrupting files (last deleted several files on my root
partition particularly fstab causing current problem)
</BlockQuote></STRONG></P>
<BLOCKQUOTE><IMG SRC="../../gx/dennis/bbub.gif" ALT="(!)"
HEIGHT="28" WIDTH="50" BORDER="0"

Are you sure that e2fsck is doing the "destroying" here?
It seems more likely that e2fsck is attempting to recover
from damage that's being down to your filesystem during the
previous session.
</BLOCKQUOTE>
<P><STRONG><IMG SRC="../../gx/dennis/qbub.gif" ALT="(?)"
HEIGHT="28" WIDTH="50" BORDER="0"

This problem has caused me to re-install several times which timakes a
long time on my system due to repeated Sig 11 faults.
</STRONG></P>
<BLOCKQUOTE><IMG SRC="../../gx/dennis/bbub.gif" ALT="(!)"

Whoa!
</BLOCKQUOTE>
<BLOCKQUOTE>
Have you read the Sig 11 page (<A HREF="http://www.BitWizard.nl/sig11"
>http://www.BitWizard.nl/sig11</A>)?
</BLOCKQUOTE>
<BLOCKQUOTE>
The bad news is that you probably have some bad memory or
some other hardware problem. Did you check the "Scan for
Bad Blocks" option when creating your swap partitions and
filesytem? If not, go back and try that! Then go through
the SIG 11 FAQ in detail.
</BLOCKQUOTE>

Any help would be appreciated

Be sure you are enabling the "Unix98 PTY Support" option
under "Character devices" when compiling these new kernels.

Try taking out first one, then the other of your
memory modules (presuming that you have a couple of
32Mb DIMMs or SIMMs). If not, see about getting another
memory module and trying that in the system. If that
works, or you can't get more memory, then take your existing
RAM in for testing.
</BLOCKQUOTE>
<BLOCKQUOTE>
Most SIG 11s are caused by faulty RAM. Nothing works your
RAM like UNIX and Netware. They are a better burn-in
test then any "memory test" software, or even test bench
equipment. (They <EM>are</EM> the real world, whereas the test
software and hardware are simulating the load that they
create).

Even aside from the likelihood that you're suffering from
hardware problems, I have to say again that I don't like
the state in which GNOME was pushed into RH 6.0. I've seen
its components dropping core files all over the few systems
where I've run RH 6.x, and I've heard that this is the case
for just about everybody. core files are a symptom of bugs.
When almost everyone is getting core files in "normal
operation" then the product/package is not ready for
production use. Let's not adopt the Microsoft attitude
towards "1.0" products.
</BLOCKQUOTE>
<BLOCKQUOTE>
With the upcoming release of RH 6.1 I certainly hope <A HREF="http://www.redhat.com/">Red Hat</A>
has stabilized their flagship GUI.
