Slashdot Mirror

Marius Nestor, reporting for Softpedia (condensed): Linux kernel 4.6.1 is already here, only two weeks after the official launch of the Linux 4.6 kernel series. For those not in the loop, Linux 4.6 branch is the latest and most advanced kernel branch available right now for GNU/Linux operating systems, but it looks like its adoption is a little slow at the moment. "I'm announcing the release of the 4.6.1 kernel. All users of the 4.6 kernel series must upgrade," says Greg Kroah-Hartman. "The updated 4.6.y git tree can be browsed at the normal kernel.org git web browser."
Some users are apparently facing boot failure issue on the latest version. An anonymous tipster tells Slashdot: Several folks on the web have reported a regression in the latest Linux kernels, starting with 4.6.1 and including the 4.7 beta that prevents booting and drops to busybox, at least the one supplied by the Ubuntu PPA. The boot sequence ends with "address family not supported by protocol: error getting socket" and then, "error initializing udev control socket" (screenshot here).

Matthew Helmke (personal blog) is the author of the newly published 11th edition of Ubuntu Unleashed (published by Pearson); this updated edition of the book will cover the OS through Ubuntu's 15.10 and (forthcoming) 16.04 releases. Helmke is also a former Ubuntu Forum administrator, a musician, an entrepreneur, and a long-time Slashdot reader who now leads a "nice quiet life in Iowa." Ask Matthew about what it's like to be a Linux book author and community leader, and his thoughts on Canonical, the goods and bads of modern Linux distributions, and the future of Ubuntu -- especially relevant with the upcoming release of the first Ubuntu-based tablet. (Remember, Matthew isn't responsible for gripes you may have with either Ubuntu or Canonical, but he might have some good solutions to particular problems.) Ask as many questions as you'd like; we just ask that you keep them on-topic, and please stick to one question per post.

First time accepted submitter TWX writes I've been out of computers as a serious home-hobby for many years and in returning I'm aghast at the state of documentation for Open Source projects. The software itself has changed significantly in the last decade, but the documentation has failed to keep pace; most of what I'm finding applies to versions long since passed or were the exact same documents from when I dropped-out of hobbyist computing years ago. Take Lightdm on Ubuntu 14.04 for example- its entire configuration file structure has been revamped, but none of the documentation for more specialized or advanced uses of Lightdm in previous versions of Ubuntu has been updated for this latest release. It's actually harder now to configure some features than it was a decade ago. TLDP is close to a decade out-of-date, fragmentation between distributions has grown to the point that answers from one distro won't readily apply to another, and web forums for even specific projects are full of questions without answers, or those that head off into completely unrelated discussion, or with snarky, "it's in the documentation, stupid!" responses. Where do you go for your FOSS documentation and self-help?

itwbennett writes "Software development isn't a cakewalk of a job, but to hear programmers tell it (or at least those willing to grouse about their jobs on Quora and Ubuntu Forums), what makes programming hard has little to do with writing code. In fact, if the list compiled by ITworld's Phil Johnson has it right, the single hardest thing developers do is name things. Are you a software developer? What's the hardest part of your job?"

An anonymous reader writes "Scheduled to be released next month, Ubuntu 12.10 now includes both Amazon ads in the user's dash and by default an Amazon store in the user's launcher. The reason for these 'features'? Affiliate revenue. Despite previous controversies with Banshee and Yahoo, Canonical is 'confident it will be an interesting and useful feature for our 12.10 users.' But are the 'users' becoming products?" Update: 09/22 19:35 GMT by T : Reader bkerensa scoffs, calling the Amazon integration unobtrusive, and says objections to its inclusion in the OS should be ignored, "because in reality ads will not be found in 12.10 unless you are seeing them on a third party website you go to in a web browser." He's got screenshots.

First time accepted submitter Rzarector writes "Good News Everyone! Thanks to the Ubuntu Gnome Community and Jeremy Bicha, it seems that the popular distribution will ship a flavor with a relatively pure GNOME experience in the next release cycle, on October 18. At this point the effort is community based, but hopefully GNOMEbuntu will make it as an official Canonical spin, similar to Kubuntu, Xubuntu, et cetera, in the 13.04 release. This is the story: At the Ubuntu Developer Summit in May, some discussions took place on the need for a Gnome spin. On August 13, Jeremy Bicha posted on Gnome mailing lists about looking a name for the new Ubuntu derivative. After that, I had no news till Stinger gave us a thread in Ubuntu Forums. On there, Jeremy talks about working on an Alpha version! So I contacted him and he verified that GNOMEbuntu will be released together with Ubuntu 12.10."

An anonymous reader writes "Ylmf, famous for pirating Windows XP, have just released a version of Ubuntu that looks just like Windows XP. Really, really similar. Apparently because Microsoft were cracking down on the actual Windows XP pirating — though I think they will still suffer for ripping off the GUI exactly." Of course, if that's the sort of look you like for your desktop, you need not risk any download cooties or language barriers; a reader in the Ubuntu Forums suggests this instructional video for giving Gnome the XP treatment.

DesiVideoGamer writes "John Carmack, the lead developer for id's Tech 5 graphics engine, does not plan on making a Linux port for the new engine. From his e-mail: 'It isn't out of the question, but I don't think we will be able to justify the work. If there are hundreds of thousands of Linux users playing Quake Live when we are done with Rage, that would certainly influence our decision.' One of the reasons for not making a Linux port was due to the fact that the new engine 'pushes a lot of paths that are not usually optimized' and that the Linux port would have to use the binary blob graphics driver in order to work."

sukotto writes "Ubuntu recently released an unannounced and experimental 'multisearch' extension to Firefox alpha 3, apparently in an effort to improve the default behavior of new tabs and of search. In a response to one of the initial bug reports the maintainers mentioned that the extension's other purposes were 'collecting the usage data' and 'generating revenue.' Since this extension installs by itself and offers no warning about potential privacy violations, quite a few people (myself included) feel pretty unhappy. The only way to opt out is to disable the extension manually via Tools > Add-ons." Most posters to this Ubuntu forum thread are not happy about multisearch.

Ryan1984 writes "Only a week after the bad press coverage regarding the Linux-related bugs in a number of motherboards released by Foxconn (which turned out to be the AMI BIOS that several board makers use), Foxconn is the first vendor out with a publicly released test patch that fixes the bulk of the problems, allowing kernel 2.6.26 to run well on the afflicted boards. The remaining issues appear to either be kernel bugs in builds earlier than 2.6.26, issues with the Intel chipset itself, or minor annoyances that Foxconn is still working to resolve. Foxconn representative Heart Zhang has posted on the Ubuntu forums (where the situation began), apologizing for the issues, thanking Foxconn customers and the community at-large for their feedback, and promising that Foxconn will take Linux support and testing seriously, going forward."

Noodlenose notes a thread up on the Ubuntu forums, where a user is questioning the practices of hardware manufacturer Foxconn. The user describes how his new Foxconn motherboard caused his Linux install to freeze and fire off weird kernel errors. He disassembles the BIOS and concludes that a faulty DSDT table is responsible for the errors. Even though the user makes Foxconn aware of the problem, they refuse to correct it, as 'it doesn't support Linux' and is only 'Microsoft certified.' The user speculates darkly on Foxconn's motives. Read the forum, read the code, and come to your own conclusions. "I disassembled my BIOS to have a look around, and while I won't post the results here, I'll tell you what I did find. They have several different tables, a group for Windows XP and Vista, a group for 2000, a group for NT, Me, 95, 98, etc. that just errors out, and one for LINUX. The one for Linux points to a badly written table that does not correspond to the board's ACPI implementation.' The worst part is Foxconn's insistence that the product is ACPI compliant because their tables passed to Windows work, and that Microsoft gave the the magic WHQL certification."

Theovon writes "I just built a high-end quad-core Linux PC dedicated to number-crunching. Its job is to sit in the corner with no keyboard, mouse, or monitor and do nothing but compute (genetic algorithms, neural nets, and other research). My issue is that I would like to have something like persistent terminal sessions. I've considered using Xvnc in a completely headless configuration (some useful documentation here, here, here, and here). However, for most of my uses, this is overkill. Total waste of memory and compute time. However, if I decided to run FPGA synthesis software under WINE, this will become necessary. Unfortunately, I can't quite figure out how to get persistent X11 session where I'm automatically logged in (or can stay logged in), while maintaining enough security that I don't mind opening the VNC port on my firewall (with a changed port number, of course). I'm also going to check out Xpra, but I've only just heard about it and have no idea how to use it. For the short term, the main need is just terminals. I'd like to be able to connect and see how something is going. One option is to just run things with nohup and then login and 'tail -f' to watch the log file. I've also heard of screen, but I'm unfamiliar with it. Have other Slashdot users encountered this situation? What did you use? What's hard, what's easy, and what works well?"

GerbilSoft writes with news of a major security hole in Samsung's proprietary Linux printer drivers. From the Ubuntu Forums: "Just to inform you about a recent post on the French Ubuntu forum about Samsung drivers (sorry, in French). [Google translation here.] It appears that Samsung unified drivers change rights on some parts of the system: After installing the drivers, applications may launch using root rights, without asking any password. What is more, you may be able to kill your system, by deleting system components, generally modifiable only by using sudo." GerbilSoft adds: "Among the programs that it sets as setuid-root are OpenOffice, xsane, and xscanimage."

An anonymous reader writes "I had a surreal experience with Dell today. My boss asked me to order a new computer for our small, non-profit business. Wanting to support Dell in their decision to sell computers with Ubuntu installed, I decided to order one. First, I talked to a small business representative, who informed me that I could not order one of the Ubuntu-based computers through the small business department. I had to go through the "home and home office" department. I called the Home office department. I asked the representative if I could buy one of the ubuntu computers for my company. She said (and I quote), "these Dell computers are designed for personal use only, as long as you use it for personal use, you can purchase one." So I lied and said I would.... Next, I tried to buy it on our business credit card. They would have none of that. She told me that I had to buy it through a personal card. Now, as a non-profit, our business does not pay sales tax (10% in Tennessee). Had I bought it with my own card, I would have had to pay tax (~$90), which my company would not have reimbursed me for. So.....no Dell today."

bobbocanfly writes "Another crack in the Windows Genuine Advantage wall. A user at UbuntuForums.org managed to validate an Ubuntu installation as a genuine copy of Microsoft Windows and get to the download page of Windows Defender, using IE4Linux and Wine. (Here is an OGG video of the process.) Along with the advancement of LiveCD technology, this could spell the end of Microsoft's control over who gets their updates."

Theovon writes, "It's only been two days since the announcement of the official release of Ubuntu 6.10 (Edgy Eft), and the fallout has been very interesting to watch. By and large, fresh installs of Edgy tend to go well. Many people report improved performance over Dapper, improved stability, better device support, etc. A good showing. But what I find really interesting is the debacle that it has been for people who wanted to do an 'upgrade' from Dapper (6.06). Installing OS upgrades has historically been fraught with problems, but previous Ubuntu releases, many other Linux distros, and MacOS X have done surprisingly well in the recent past. But not Edgy." Read on for the rest of Theovon's detailed report.

Reports are flooding in to Ubuntu's Installation & Upgrades forum from people having myriad problems with their upgrades. One user described it as a 'nightmare.' Users are producing detailed descriptions of problems but getting little help. This thread has mixed reports and is possibly the most interesting read. Many people report that straightforward upgrades of relatively mundane systems go well, but anything the least bit interesting seems not to have been accounted for, like software RAID, custom kernels, and Opera. Even the official upgrade method doesn't work for everyone, including crashes of the upgrade tool in the middle of installing, leaving systems unbootable, no longer recognizing devices (like the console keyboard!), reduced performance, X server crashes, wireless networking problems, the user password no longer working, numerous broken applications, and many even stranger things. Some of this is fairly subjective, with Kubuntu being a bit more problematic than Ubuntu, with reports that Xubuntu seems to have the worst problems, and remote upgrades are something you don't even want to try. Failed upgrades invariably require a complete reinstall. The conclusion from the street, about upgrading to Edgy, is a warning: If you're going to try to take the plunge, be sure to make a backup image of your boot partition before starting the upgrade. Your chances of having the upgrade be a total failure are high. If you're really dead-set on upgrading, you'll save yourself a lot of time and headache by backing up all of your personal files manually and doing a fresh install (don't forget to save your bookmarks!).

Viraptor writes, "Debian is ready to change the name of Firefox in its distributions, beginning with Etch. They say it can be done within a week. The reasons stem from Mozilla's recent insistence on trademark fidelity and its preferences regarding Firefox patches. Debian doesn't want to accept the original trademarked fox & globe logo; they don't see it as really 'free' to use. On the other hand, Mozilla doesn't want Firefox distributed under that name if it lacks the logo. Mozilla also wants Debian patches to be submitted to them before distribution, and claims that's what others (Red Hat and Novell) are already doing. But some believe development and releases will slow down if distribution-specific patches have to be checked and accepted first. We will surely see more clashes between copyright claims and 'really free' distros such as Debian. Ubuntu is also asking similar questions." No word yet what the new name will be or what the logo will look like.

BBitmaster writes "An extremely critical bug and security threat was discovered in Ubuntu Breezy Badger 5.10 earlier today by a visitor on the Ubuntu Forums that allows anyone to read the root password simply by opening an installer log file. Apparently the installer fails to clean its log files and leaves them readable to all users. The bug has been fixed, and only affects The 5.10 Breezy Badger release. Ubuntu users, be sure to get the patch right away."

bored2k writes "Kevin Carmony, President and CEO of Linspire, Inc., is using the Ubuntu Forums to ask for input and explain why he thinks a popular and heavily focused on usability distribution like Ubuntu needs Linspire's $20 per-year CNR service. From what he says, both him and Mark Shuttleworth (Canonical/Ubuntu's founder) like the idea. Would CNR honestly help Ubuntu grow, or is it just a scheme to cash in on it's success?"

Flashless Dancer asks: "Despite numerous online campaigns, blogs and forum postings, Macromedia has failed to release a 64 bit version of it's popular Flash Player for 64 bit architectures. Growing outcry in the Linux community recently spawned the online petition at PetitionOnline, but this seems to have fallen on deaf ears. A recent posting to Macromedia's technotes, back in September, offers this explanation and advice to users and developers who are growing increasingly concerned that users with 64 bit architectures are unable to view online content created with Flash. It explains that users must downgrade to 32 bit browsers and use the 32 bit plugin. This simply isn't a good option for most users, in fact many Linux distributions, including FC2/3/4 install 64-bit browsers with their 64-bit distributions. This seems to breathe new life into the old GplFlash Project which is now back, after some time on the back burner. Future development of GplFlash2 promises support for Flash 6/7 but remains in development for now. Open speculation in chatrooms and web forums alleges all sorts of conspiracy theories but, what I'd like to know is: What's the real difficulty here for Macromedia?"
