Ubuntu 12.04 applications launching problem
This fault occurred a few days ago out-of the-blue, that is, seemingly unprovoked. It has prevented launching any applications other than those (with one exception as described below) that happen to be among the launching icons on the LHS of screen. The two abnormalities are: 1. Dash Home will not list any applications nor find any. 2. Ubuntu Software Centre will not launch from the side icon providing only a blank screen and then, upon closing the window, leaving a message saying that it is not responding. Notes: Dash Home searches for and finds Files and Folders, Music and DVDs (but not applications). I have the home directory saved on an external hard drive (I use Grsync). By chance I have Byobu Terminal in the launching panel (and it launches). My question is: What is the best way of restoring proper operation. For example, if it is best to upgrade, should I go straight to 14.04 from a disk or upgrade sequentially to 14.04 as I did to get 12.04 (or doesn't it matter which way)? Or, can I do something from Byobu Terminal. Thanks, Geoffrey Combes -- ubuntu-au mailing list ubuntu-au@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-au
Re: PDF printing problem
In a previous posting I mentioned my problem with printing PDFs and some other documents where some of the page is cut off. I came up with a complicated answer but the best answer is much simpler: For example if the page size is A4 select paper 'A4 borderless 297x 210' rather than 'A4'. Problem solved. In hindsight it's obvious isn't it? Geoffrey -- ubuntu-au mailing list ubuntu-au@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-au
Arduino loading problem
I am trying to load a program into an Arduino UNO microprocessor. The program is a AZ-EL rotator controller. It has been successfully uploaded by others using the Ardunio IDE for Windows. I am using the IDE downloaded (from the Ubuntu software centre) to Ubuntu 12.10LTS, my current system. I began using the port USBo which I think is the correct one for serial transfer. The IDE window is now listing USB1. After compiling this message is received: "avrdude: stk500-recv(): programmer is not responding" Could someone tell what initial part of this message might mean. By the way I can say that the program has not uploaded because the new Arduino UNO came with a LED blinking program on it and this continues to run.

Linux Tablet
Is it true that an operating system by Canonical or another is available for someone to produce a tablet comparable with others on the market? If so how soon should be reasonably expect one to appear? Presently I own neither a tablet nor a mobile phone. I'm not in a hurry to buy such time-wasting toys but I guess I must soon. Should I buy a tablet (say, rather than a notebook) for portable use I would prefer that it has a Linux operating system. By the way I am an engineer and a licensed radio amateur (time-wasting, yes, but also a thinking hobby) so I am not averse to wireless communication. Your views would be of interest to me.

Re: PDF printing problem
Thanks Jarrod for the advice. I tried another viewing program but the result was precisely the same as I have described. However there is a simple way around the problem which I have used before but which I had forgotten about. It is: Open GIMP and import. >From 'Print Image Settings' open the print dimensions fully. Tick the box 'Ignore Page Margins' (just to be sure) The print is on a full page and perfect as one would expect from GIMP. This takes a bit longer of course but is sure-fire. Also it allows one to adjust the image. For example I recently printed a PDF of text that was barely readable because it was in pale grey. I used the 'Threshold' colour tool in GIMP to get a dark black text print. Geoffrey -- ubuntu-au mailing list ubuntu-au@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-au
PDF printing problem
I am running 12.10LTS with an HP Photosmart 5520 printer. When I print from a PDF file, irrespective of its source, the print area is displaced upwards on the paper. As a result printing at the top of the printed area is partly or wholly missed. To print PDFs successfully I must do so with MS XP on another machine and a Canon printer. The HP prints LibreOffice files correctly. I do quite a bit of desktop publishing from PDF files which I produce in 12.10LTS but then I must move the files across to XP to print them. This is annoying. Printing previews are OK, but the printing is not and I can't find any way of adjusting for the error. Your help would be appreciated.

12.04 LTS and Telstra 4G moble wireless modem - Resolution
As of today I am connecting successfully to 12.04 LTS via the new Telstra modem a Sierra AirCard 320U. The key to getting there was Jared Noriss's advice to obtain and install the latest Sierra driver for Ubuntu. He provided the website. The procedure I used to install the driver was given in my mailing dated 4 September. Hopefully this driver will be valid for future Ubuntu versions at least for some time. I had further problems (preventing connection) related to registering the modem. These were: 1. To register one must install the software provided on the modem in a Windows OS. Installation my old XP crashed halfway through the process preventing me from using the Windows connection manager. 2. The software was successfully installed on a Windows 7 laptop but registration could not be completed because the modem oscillated between search and ready to connect. This is not uncommon and it is thought that the modem is trying more than one band (it has three). 3. It is not possible to register using the previous user name (as I was doing). All of these problems were resolved by the Telstra (technical) consultant in the local Telstra shop. He carried out the registration on his laptop and, importantly at my request, kept my previous user name and so preserved my email address. The upside is that the new modem and its link to Telstra is much faster than my old modem.
