Intermittent Disaster
 

My Fedora 7 and 8 are working fine. Typically I bring up my Firefox
web browser and try to read what is on the Google page. It is from a
newspaper and it has a lot of advertising and pop-ups. While all this is
coming up, sometimes it keys a sudden loss of the screen due to a full
screen cross-hatch, and neither keyboard or Mouse work. The only thing
to do is turn off power to the computer.


This is an unacceptable event. It makes me MAD and since using ext3
I can turn off the computer and not loose anything but sometimes I
reboot and the problem will appear again in just a few minutes.


This problem started right after I changed to this computer. And so
did the need to get a Nvidia driver for Linux. So I think it must be the
Nvidia software generating this. But I do not know this for a fact
because the problem is very intermittent.


I hate this problem so much I plan to load another F8 and see if one
without Nvidia has the problem. The screen is just 800x600 but I can get
Firefox working and see what happens.

You don't say what extensions you have installed in Firefox, nor
whether you even have it behind a proxy. Before doing a lot of work, I'd
try (if you haven't) putting firefox behind privoxy, and getting the
NoScript and Adblock extensions.

If you already have those defenses, I'm no judge what to try next.

I do not know about your video driver problem.

But to help your Firefox experience I have four suggestions.

- ---------------------------------------------
1) Install the Adblock Plus extension

This stops all, or most, of those adds and speeds up the pages loading.
- ---------------------------------------------

2) Install the Flashblock extension.

This blocks flash from all sites and you can, as you wish, allow flash
from certain sites as you choose.
- ---------------------------------------------

3) Remove all of the languages that you do not need from the extensions.
English is 'built-in' and these are checked for updates each time you
load Firefox. Slows down the loading. This has to be done as 'root' and
they will be replaced with each Firefox upgrade from Fedora.
- ---------------------------------------------

4) use the squid proxy

Yum install squid

service squid start

goto the services menu and set squid to start on boot in levels 3 and 5.

save and close the window

start Firefox > Edit > Preferences > Connections 'settings...' button

select manual proxy configuration

in the box HTTP Proxy type 127.0.0.1

in the box Port type 3128

check the box Use this proxy for all protocols

click ok

set Cache to 0 (that is the number zero)

click clean now

click close
- ---------------------------------------------

Enjoy the speed up

You could also be having an overheating problem.* You might check to
make sure your fans (case, chip, power supply) are working correctly

and the intakes are not full of lint.

I have turned on the two filters and they do work well! The interent
goes through localhost and it works fine. I have all the languages
turned off.


I like the way your web page is laid out and the step-by-step
instructions. I can't get the likes of rday and others to even talk
about that kind of writing. A real shame.


The web page is saved here and the other changes will be added after I
figure out where they go :-)

Perfect! I had no clue! Squid does a helluva job, I just didn't know
about it. Thanks! Ric

There is no single government agency that views sustainability through a broad

decisions. Any model of sustainability that is driven solely by an economic
engine is deficient if it is incapable of taking into account social values.

I seem to recall that if you had your networking set up properly in the
first place, Squid could work out what your hostname is for itself.
Though you could specifically set it in the Squid configuration file
(necessary for machine with several hostnames, and you didn't want to
use the default).

Brute force approach: Open the squid configuration file in an editor,
and search through it for "name", read the comments nearby. You'll find
the place where you can set it soon enough.

But is your hosts file set up correctly? You should have something
like:

127.0.0.1 localhost.localdomain localhost
192.168.1.2 mymachine.example.com mymachine

Where the second line is written to be applicable to your machine,
rather than my example (using your IP, your fully-qualified domain, and
your hostname). The first line should, generally, be left as I've shown
it, and not adorned with local machine names, as well.

Though, if like me, you use a DNS server, you don't have to do anything
with your hosts file, just ensure your DNS server is configured
correctly.

Go back and read David Boles step-by-stepper. I only did as he wrote,
and localhost was only set in Firefox in his example.

By default you should already have "localhost" set to 127.0.0.1
in /etc/hosts, here's mine with my local junkyard network:

[root@iam maps]# more /etc/hosts
127.0.0.1 localhost.localdomain localhost
192.168.1.104 ru.wayward4now.net ru
192.168.1.103 ima.wayward4now.net ima
192.168.1.102 ur.wayward4now.net ur
192.168.1.101 iam.wayward4now.net iam


So just doing those edits to firefox should make it run just dandy if
your /etc/hosts file has localhost set.

Fire up Firefox

click on edit > preferences > advanced > network > settings
and you'll see the page he references. click on the button = 'manual',
then add the following values:

HTTP proxy [127.0.0.1] Port [ 3128]

That should fire up when you restart Firefox. Did I leave anything out
David? Thank you for your instructions. It was nifty. Ric
