What kind of alchemy do you use to find these hits? I've been searching for support on Ubuntu with the XPS-13 9350 since April and never found that page. Even when I typed 'Ubuntu on Dell XPS 13 9350' into Google just now, it never came up (in the first page of hits anyway). I had to add 'certification' to the search string to find it and even then it was over half-way down the page. Of course I would have had to know so much about that page to invent that search string that I might as well have gone straight there ;-( > Perhaps others have clicked that link and put up questions in the past > with interesting answers. No such luck I'm afraid. Very few hits on 9350 and only about a dozen on XPS-13. Nothing that was useful. -- Terry Coles -- Next meeting: Bournemouth, Tuesday, 2016-11-01 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ New thread: mailto:dorset@mailman.lug.org.uk / CHECK IF YOU'RE REPLYING Reporting bugs well: http://goo.gl/4Xue / TO THE LIST OR THE AUTHOR

It was always this way, especially before PC vendors started supporting Linux Back in 2008 (AFAIR), Dell were only just starting to support Linux, so were probably at the other end of the process that they appear to be ending this year. My main gripe with Dell in this instance is that they actually charged more for this machine than its Windows counterpart, but provided less support. Windows customers get access to downloads of the driver, utilities and an image of the factory installation for recovery purposes. If you drill down into the Support pages for recent versions of the XPS-13 Developer Edition and other Linux laptops, they *used to* provide support. I don't recall the specific product numbers, but several have support for not one, but several versions of Ubuntu, eg 10.04, 12.04, 14.04 and you can download Factory images from their website. This one (designated 9350) has none of that and the Restore to Factory Defaults hot-key is not active, even though the recovery image occupies a partition on the machine. When I naively upgraded my machine to 15.10 and thereby lost all the Dell Drivers, they were unable to tell me how to get at that recovery image or provide me with a copy of the image, even though the factory must have one. Initially, I was told that they couldn't help me because this Operating System was unsupported. In the end I took legal advice and they gave me a new machine, but they still don't support it. How not to keep your customers happy. -- Terry Coles -- Next meeting: Bournemouth, Tuesday, 2016-11-01 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ New thread: mailto:dorset@mailman.lug.org.uk / CHECK IF YOU'RE REPLYING Reporting bugs well: http://goo.gl/4Xue / TO THE LIST OR THE AUTHOR

Re: [Dorset] Problem with security certificate
Many thanks to Keith, Terry and PeterM for taking part - I can feed useful information back to the manufacturer. I didn't choose the TG589 - it came from the ISP (Fleur Telecom) when I upgraded to "superfast" broadband. I hadn't heard of Web browsing interception. I found a control "Use Network Intercept" and set it to "Off" and restarted the router. Problem persists, so I'll have to see what the manufacturer says.

Re: [Dorset] Meeting 4.10.16
Hi again,

I'll try and give a very brief overview of the questions' subject.
A high-level programming language lets one write code that looks like
this.
lives = lives - 1
if lives == 0 {
print("Game Over!")
}
Even if you don't program, it's fairly understandly given the meaningful
variable name, "lives", and the clue from the text string that's being
printed.
A compiler is a program that understands a particular high-level
programming language and produces an equivalent program in assembly
language. This is low-level. The above becomes
LDA lives // Load the accumulator with the contents of address live.
DEC A // Decrement accumulator.
STA lives // Store the accumulator back to address live.
BNZ endif // If the accumulator is non-zero, branch to endif.
ADR str0 // Place the address str0 into the accumulator.
PSH A // Push the accumulator onto the stack.
JSR print // Jump to the subroutine, it will return here.
.endif
// ...Further on.
.lives
.EQUB 3// Initial number of lives. (POKE this for more!)
.str0
.EQUS "Game Over!"
.EQUB 0// ASCII NUL terminator.
An assembly language is specific to a processor's instruction set, e.g.
x86, amd64, ARM, 6502, Z80, Sparc, POWER, PIC, ... This means writing
in assembly isn't portable between processors. In comparison, that
high-level program above can be, and the high-level language needs
learning once to program on many processors whereas assembly language
needs learning afresh each time.
A symbolic assembler is another program that takes the text file
containing that assembly language and assembles it into a file of bytes
containing the bit patterns that the processor needs. It's a one-to-one
translation, for example a DEC instruction might be a byte where the top
seven bits are ten, 0001010, and the bottom bit is 0 for the accumulator
and 1 for the X register. `DEC A' is then `00010101' in binary, or 21
in decimal. Because binary numbers get long quickly, they're often
written in base 16, hexadecimal. 00010101 is 15 in hex.
The above assembly code becomes
1100 // LDA lives
00010101 // DEC A
10100100 // STA lives
11101000 // BNZ endif
01000101 // ADR str0
00010001 // PSH A
00111001 // JSR print
// ...Further on.
0011 // .EQUB 3
01000111 // 'G'.
0111 // 'a'.
01101101 // 'm'.
01100101 // 'e'.
0010 // Space.
0100 // 'O'.
01110110 // 'v'.
01100101 // 'e'.
01110010 // 'r'.
0011 // '!'.
// .EQUB 0
Or as hex,
84 15 a4 e8 45 11 39 ... 03 47 61 6d 65 20 4f 76 65 72 21 00
Life without an assembler got boring quickly, forging life-long
synapses, as those of us that have done it by hand can attest.
(10 REM 0123456789012... RET is c9.)
The output from the assembler is the "executable" that later ends up
somewhere where the processor starts to execute it, one instruction at a
time on each signal from the CPU's clock. The CPU's logic circuits made
from transistors, the embodiment of the instruction set, are fed the
bits making the instruction, with 1 bits being a voltage, and 0 being
ground. They have the side effect the instruction represents, e.g. `DEC
A', and the CPU starts on the next instruction on the next clock pulse.
There's a bunch of videos working through from the electronics side from
the guy that built the Megaprocessor.
http://www.megaprocessor.com/stepping-stones.html
Unlike the book, they're free. :-)
Cheers, Ralph.

Kernel version 4.8 (released at the weekend )and notwithstanding the bug that was only noticed by Linus afterwards)), together with versions 4.4, 4.5 etc bring more support for the Touchscreen and the Skylake processor. Out of the box the XPS-13 Developer Edition gave appalling benchmark results compared to an ancient laptop that Paul brought to a Meeting a few months ago. The kernel version in Ubuntu 14.04 is 3.19, which has zero Skylake support. When I installed Kubuntu 16.04, the benchmark results shot up (that has kernel Version 4.4). When I booted into the latest version of Parted Magic the benchmark results were even better (kernel Version 4.5). In addition, Dell include about half a dozen proprietary drivers that provide Touchscreen support (you can use it as a graphics tablet of a sort). With the standard Ubuntu 14.04 (from the Ubuntu website), the Touchscreen hardly worked at all. In Kubuntu 16.04, the Touchscreen works pretty well but the graphics tablet functionality is still missing. I'm hoping that the kernel will eventually support all of the Touchscreen functionality and that the graphics subsystem (whatever it ends up being) will support automatic display scaling, (like Win 10 does) because text is unreadable on a 13" screen at 3200x1800 resolution unless the fonts are all scaled up (which only works for some things). In the end I have to run the screen at 1920x1400 to make it usable, which kind of defeats the object of having a high-res display. So. As I said in my earlier post, the XPS-13 is a really nice machine, but it is let down by the total lack of support from Dell. -- Terry Coles -- Next meeting: Bournemouth, Tuesday, 2016-11-01 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ New thread: mailto:dorset@mailman.lug.org.uk / CHECK IF YOU'RE REPLYING Reporting bugs well: http://goo.gl/4Xue / TO THE LIST OR THE AUTHOR
Re: [Dorset] Restoring Grub on an EFI Machine
This thread is a little depressing because at work I was given a brand new 15" MacBook Pro on arrival which is very lovely I suppose, but I hate it. It seems that installing Linux on it (other than in a VM) is not allowed, and besides I get the impression it won't work very well. It seems that many people have Dell's with Linux, usually self installed over Windows. I was thinking of asking if I could swap for a Dell, and the developer edition ones are the obvious choices. However, the more you look at them the more you see the potential problems. I hate the idea of buying a Windows one and taking pot luck on Linux to run well on it but that may be no worse.

I don't actually *know *that Dell put it there, but it isn't in the stock distros, so I'm assuming that they caused it to be put there.

Last evening and this morning, I've been pondering why Dell set that flag at all. I'm assuming that this was to protect their support staff from people ringing them up and trying to get problems solved when the default shipped version had been upgraded or superseded with a dual-boot, as I had done. However, there are two arguments against that. First, anyone who installs an extra distro will find it working perfectly at first because update-grub will have been run by the new distro's installer not by the shipped distro. That all works fine until the shipped distro has another kernel update, as happened a week or so ago. Now grub-update ignores the new distro's partition and the user is left wondering why it has broken. As with myself, this might only be discovered weeks after the kernel update that triggered the problem. The second argument against that is that Dell are not supporting Ubuntu on this machine anyway; only W10, so they created a problem for their users for absolutely no purpose whatsoever. So the message here is, no matter how good the reviews are (and they are good), don't be tempted into buying a Linux Laptop from Dell. They are not providing anything like the same level of support that a Windows user gets, but they charge a premium price. It is a nice laptop, but I'd have been better off by the Windows one and dual-booting that.

Don't know if it will work for your or not terry. Thanks for the link Tim, I had actually tried that (it is included on the Parted Magic live disc). It allowed me to boot into the lost partition, but didn't seem to offer a repair tool. Maybe that wasn't included in the Parted Magic version of the tool, because the full PM toolset includes a boot repair tool (which didn't work for me).
