Open the package manager GUI (I forget what it's called), and search for libdvdcss2 and install that. That will allow you to play DVDs.

Could be; if you want to check you RAM for errors, run memtest86 off the Ubuntu install CD. I don't think it's because you have 256MB - all that means is that Ubuntu will use swap space as RAM instead, which is slower.

Also check your /var/log/Xorg.?.log files for errors as it's likely to be an X related problem. Each error line starts with EE, so you can easily grep for these:
Code:
sudo grep EE /var/log/xorg.?.log | less
If you get lots of lines with error messages, those will give you an indication as to why Ubuntu's freezing all the time.

When you say freezing, what do you mean? Does the screen go blank? Does the mouse cursor move? Does the hard disk activity light flicker? Can you hear the hard disk going? Does the machine "unfreeze", or do you have to power it off? Do the keyboard lock indicator lights change when you press caps lock and so on (if you have such lights on your keyboard)?

Thanks for your reply Guys,
When it freezes everything stops and I have to hit Reset to get it going again. ???.
This is the third install I've tried, thinking it was the install but it still happens from time to time, no apparent relevance to any program, it even did it on desktop ???.

PWC 10 I tried to install Open the package manager GUI (I forget what it's called), and search for libdvdcss2 and install that. That will allow you to play DVDs.I couldn't find it in synaptic manager so I googled it and found a site with all the instructions ie. line commands, to install it but at the end of everything I got the message " no installation candidate",
what does that mean ?? and how do I get around it.

I'd look at the /var/log/messages log file. Go to the bottom of the file, then search upwards for "restart". You should be able to locate the time of the last reboot of the system. (you can also use the uptime command in a terminal window to work out when the last boot was and just find that time in the /var/log/messages file). From the last reboot time, look up and see if there are any error messages in the file just before the last boot. Maybe there will be some error messages there.

Of course, there are some problems which happen so quickly that no error messages can be saved to the log. These problems are often quite difficult to diagnose. Two common causes are heat build up (the BIOS may freeze the machine if the CPU gets too hot), or a memory fault.

In the case of a memory fault, you can boot into a memory checking system. Ubuntu installs one of these be default - at the grub boot prompt, you can boot into a memory checking system. Note that memory faults might only happen after the machine has gotten quite hot, so it's a good idea to leave the checker running for half an hour or so.

In the case of heat problems, you can install thermal monitoring software which will plot the temperature of your CPU. Check out this article for how to do it in Ubuntu.

It depends on which version of Ubuntu you're running, I think. I've just installed Ubuntu 8.04 in VirtualBox, and to get the libdvdcss2 package installed, I followed the steps here: http://ubuntuforums.org/showpost.php...66&postcount=6

Searching the ubuntu forums should give you an answer for whichever version of Ubuntu you have installed.

Any help would be appreciated

Sorry, that's my fault, xorg.?.log should have a capital X:
Code:
sudo grep EE /var/log/Xorg.?.log | less
That should work.

As for your other error message, I really have no idea what that's about. It looks to me as if your computer can't resolve a web address - perhaps a problem with your ISPs DNS server?...

It might be useful if you copy and pasted the commands which you have put into your terminal before you received that error message. Please post the commands surrounded by code tags:

[code]When posting, replace this text with your pasted code[/code]

It makes it much more readable.

PWC 101 entered the new code and recieved :

[ (WW) warning, (EE) error, (NI) not implemented, (??) unknown.
(II) Loading extension MIT-SCREEN-SAVER
(EE) AIGLX: Screen 0 is not DRI capable
(END) ]

Clear as mud to me, can you help ?
p.s. I just copied and pasted the code into the terminal is that ok? or should I type it ??

The other drama seems to be with the site, I tried to Google the address and nothing, no answer, no notice just a blank screen ????

Copy and pasting is better, but you still need to surround the pasted text with [code] at the start of it, and then [/code] at the end.

I don't see anything out of the ordinary there. The first line tells you what the codes WW, EE NI and ?? mean. Then the next line has been displayed because there's a EE in SCREENSAVER, and finally the last line means you won't get any nice 3D capabilities on your display. I also have this line in my Xorg logs, and I don't get intermittent crashes.

It seems likely your problem is not related to X. Did you run memtest86 to check your memory?

G'Day Thanks for your patience I appreciate it;

Do you mean to put [] at the beginning and end of the code or do you mean to place the word code and /code in bracket at the beginning and end of the copy/paste.
The other thing is , the problem with freezing could very well be my ram or cpu, both are old and well worn,hence why I want to get another PC, but I still want to sort out this command line stuff whill I'm using this one,if I blow it, it doesn't matter so much.

In that case, to check your RAM, use the Ubuntu install CD or, if I remember correctly, Ubuntu installs it to your machine and you can boot to it from the GRUB menu. GRUB should list a number of options, one of which should be memtest86. It might take a while, but it'll tell you if it is your RAM that's bad.

Other things to consider are it might be you power supply, which without swapping in another known good power supply, is pretty hard to diagnose. Or it could be a buggy graphics card. If this is an old computer, you might have a build up of dust in some of the cooling vents, the headsink, or the fans. Invest in a can of compressed air and blast all those dust bunnies out of your computer (you'll need to open the case for this bit). There are loads of guides on the internet to show you how best to do this (http://lifehacker.com/software/geek-...ies-153409.php for example).
