Linux Support / No sound output from Ubuntu desktop - Solved!
« on: January 29, 2012, 06:31:21 pm »
My own PC with V11.10 works very well and I offered to upgrade a free desktop that came my way for a friend.  Ubuntu V11.10 loaded without problems and I even managed (with some help from this Forum) to get the wireless network going.  And the HP printer works as well! 

Sadly, though, there is no sound output.  I have searched several forums and other sites for advice, but most of it is for rather old Linux distros. 

I have used all the system checks that I can find, and used several terminal commands found on the web to examine audio drivers and hardware, but it's beginning to look as though the amplifier is not working.  I attach a file of my efforts and the results and would be glad if someone would advise me.

..... and you can use a "fallback" to Classic View without effects and get a wonderful, intuitive appearance.
Mark suggested I use the command:  "sudo apt-get install gnome-session-fallback" to get it.
It adds another option to the available appearances that can be chosen at login.

Problems all solved

TP-Link  TD-W8960N  Wireless n ADSL2+ Modem Router
The initial problem was due to me using (from previous experience) as a user-name that part of my email address before the “@”.  It appears that “user-name” now means the complete email address, and is needed when setting up the router.  It then worked flawlessly. 
But then I crashed it by me meddling with the set-up whilst trying to get the TP-Link Wireless Adapter to work.  The Device MAC Address and Cloned MAC Address had become swapped – reversing them got me back on line on a wired connection. 

TP-Link  TL-WN822N Wireless Adapter
This device worked for a few minutes then stopped. Testing it next day on an XP and two Windows 7 machines showed no response, so I have returned it to Amazon. 

EDUP  EP-N8508 Micro Wireless Adapter (802.11n)
I happened to have one lying around.  It's about the size of a USB plug. Plugging it in had no response, but trying another USB port was successful.  My Linux PC found it and connected in seconds and I now have a wireless connection. 

Laptop   Dell Latitude D505 (wireless)
It has Ubuntu 10.4 loaded, connected immediately to the network and works at considerable distances. 

The TP-Link router is very good, though I hope it lasts longer than the TP-Link adapter. 
The EDUP micro wireless adapter cost £10, works very well and does not take up any real estate. 
If one USB port doesn't work: try another!
Overall: had it not been for the faulty TP-Link adapter, the creation of a network in Ubuntu 11.10 would have been a breeze. 
My thanks to all contributors.

I found the problem.
The router setup asks for my user-name (as specified by my ISP).  Normally this is the bit before the "".  But what the new router needed was the complete address, including the "".  I now have internet access with a wired connection between the router and the PC. 
I shall persevere with the wireless connection and report back.
My thanks for your advice so far.

It would have been helpful if I had summarised the situation in my previous post so that contributors wouldn't have to trawl the whole conversation.  But first to answer your questions:
1. The old modem contained useful data such as the Virtual Path and Virtual Channel Identifiers that are standard for the UK, and other data, so it seemed a good idea to use those.
2. BT is indeed my ISP, but I discarded their home hub eight years ago as it was a pain to use and my computer was filled with useless Yahoo software.  Their Help Centre is in India and although they try hard, communication is difficult.  We don't have cable or fibre here; just very slow and unreliable telephone lines for broadband. 
3. How did I post this?  By using the old modem of course!  It's a Thomson SpeedTouch 510 V6 and it worked just by plugging it in! 
4. Let's forget the laptop and wireless connectivity for now and address one problem at a time by getting the router/modem speaking to my ISP.

My new router is a TP-Link TD-W8960N Wireless ADSL2 Modem Router.
It is connected by wire (when trying to fix it) and I have reported all the data and test results in the link two posts ago -;topic=9845.0;attach=1848. 
Thank you for taking an interest – I would be grateful for any advice.

The kit arrived.
Although I don't need a wireless connection between router and PC (only router to laptop and printer) I bought one anyway just to try it.
I followed the instructions and used data from the old modem but nothing is working after meddling for most of the day. 

It does seem to connect to a BT server, but the server objects in an unusual way, as shown in the notes.

I would be really grateful if someone with experience of setting up a wireless system with Ubuntu would help me out, and I attach a 3-page file of the set-up data I've used, and the results of the final test.

Many thanks in anticipation.

Thanks, Mark.
The TP-Link units look good, and though I'm not in desperate need of a wireless adapter, I think I'll have a go anyway.  The "works out of the box with V11.10" recommendation for the adapter is encouraging, and I am hoping this will be true for the router as well. 
I shall order them and report back - then I may need advice getting peripherals such as a printer to work wirelessly.  But one thing at a time!

One other thing: the router is described as "for BT connections".  What might that mean?  Does it refer to the plug type (I thought they were all the same) or to some characteristic of BT lines?

It depends what you want from your network.

Wireless adapter .. do you need Wireless "N" speeds, or will Wireless "G" do ? .. ie. are you likely to need to tranfer large files between PC's on the network ?
    G will be fine.  When I give the system away, the two computers will be used independently to access the internet
Router .. do you need any extra functionality over and above a "standard" router .. ie. gigabit ethernet ports, or the ability to add a USB hard drive and share it as a NAS drive, etc.
    For this application, a standard router will be fine
I take it this is for an ADSL line and not a Virgin cable connection ?
    Yes - standard ADSL.  We dream of fibre here!
then there's how pretty do you want the router to be .. purely functional, or pretty too ;)
   Pretty?!  Function before form for me!

According to this:
The Dell D505 has wireless built in .. so what is the wireless adapter you want for ?
      Oh that's good.  I didn't realise it was wireless!   For now, I don't need the desktop to be wireless, which probably simplifies everything.

Linux Support / Creating a wireless network in Ubuntu V11.10 - Solved
« on: January 04, 2012, 07:02:09 pm »
I am running Ubuntu V11.10 and, after a few glitches sorted out with help from this forum, I am very happy with it since discovering that I can run it in Classic View. 
My next task is to set up a wireless network.  My only experience of trying this in XP was disastrous so I am starting by asking for advice, having searched the Forum on the subject.   
My goal is to have my desktop wired to a router/modem (one device or a pair) and have a laptop (also Ubuntu) and printer connected wirelessly. 
Whilst Ubuntu is great at interacting with whatever device I plug into it, I want to be sure that I buy the “best” wireless adapter and router/modem combination for my purpose without getting out of my depth.  I found a web-page somewhere that recommended the  Thomson SpeedTouch 546 or Belkin N1 for Linux. 
So:  which device(s) would Forum users recommend (and why) and what advice would they offer a wireless novice in setting up such a system?
My PC is ?? without a wireless adapter. The laptop is a Dell Latitude D505 and the printer is an HP 7200 series, to be replaced with an Epson PX720WD when I give the system away to a friend.  I note Topic post 9844.0 on the subject of wireless printers. 
Oh, and a Happy New Year to all my readers.

Yes, it does make sense.  I can see that I ought to be careful in installing applications as some might be written for the Qt framework and might show some undesirable effects on Ubuntu. 
Browsing the Software Centre I note that some application names beginning with"k" are optimised for KDE (eg K3b disk-writing s/w) and some prefixed "g" (e.g. Gparted partition manager) may be based on Gnome.   But most aren't prefixed usefully and it's  not obvious which they are aimed at.  I guess I can simply un-install any that don't work as expected, and I take your point that differences are likely to be small. 

"Historically Ubuntu came with the Gnome framework (GTK) but from what I gather, since 11.04 it comes with BOTH pre-installed." - i.e. Qt as well? 

(My grateful thanks, as usual, but don't you ever get time off?)

It sort of makes sense.  I recognise the names and it's very helpful to have them put into a context. 
If I understand it:  an Application Framework is an intermediate code that allows the user to invoke applications (and simultaneously). 
Presumably application-writers must write for a particular Framework. 
Does Ubuntu come with a framework built-in or does it use GTK? 

I think I get your meaning: the desktop is a just a visual interface that interprets simple icon clicks as complicated command strings that actually invoke actions.
Such as  clicking the Update button instead of typing "sudo apt-get update".

Am I getting there?

The history of its development is rather interesting and seems to involve much "politics" as everywhere else in life.  I am reminded of the OpenOffice/LibreOffice spat.  Are Unity and Gnome just the "appearance" bits of the operating system, like Nautilus is the file manager? 

Ubuntu seems like the one to stick with, for now at least, although I am probably pushing my luck expecting to be able to use Classic View all the time. 

Thanks for the invitation - I shall make a note of any problems.

As I say - problems are disappearing as the updates flood in. 
One was when clicking on "Places/Home Folder" (Classic view, remember) It tried to open it as if it were an image folder. Not a problem as I could get there by another route.  But that's been fixed after an update.  I think it does still do that elsewhere, but I can't remember where - I'll get back to you when I encounter it again. 
This reminds me to post an item on the Pinta Image Editor.

I bought a few V11.10 discs to spread the word about Linux, but I do begin to despair that the originators of Ubuntu are inadvertently developing a Microsoft mind-set.  Making changes and adding visual tricks just because they can.  I feel this is not in the spirit of Linux.  Having said that, if I am to use a "low level" flavour of Linux, I shall have to make an effort to learn more about the workings and get to grips with terminal commands (I nearly wrote DOS commands!).   Apparently there is a Haines Manual on Linux - I shall report when purchased.

Most of your conversation is above me, but I have found System Monitor in "System Settings" - at least it is in Classic View that Mark helped me install. 
I don't like icons in general and feel more at home with words and menu lists.  That might change if eyesight fails! 
Some initial problems after installing 11.10 have gone as updates have flooded in - just a few left with individual applications.

Thanks, Mark.     I have indeed performed the update and am running V8
I am a bit concerned by Kulikov's other comment:
"ATTENTION: Due to an unavoidable ABI change, the kernel packages have a new version number, which will force you to reinstall and recompile all third-party kernel modules you might have installed. Moreover, if you use the linux-restricted-modules package, you have to update it as well to get modules which work with the new Linux kernel version."
... as I am clueless about these issues.  Will they go way if I close my eyes?
