Linux 4.15-rc7

tuxmachines.org - Sun, 01/07/2018 - 23:27

Ok, we had an interesting week, and by now everybody knows why we were
merging all those odd x86 page table isolation patches without
following all of the normal release timing rules.

But rc7 itself is actually pretty calm. Yes, there were a few small
follow-up patches to the PTI code still, and yes, there's been a fair
amount of discussion about the exact details of the Spectre fixes, but
at least in general things have been nice and calm. And we're actually
back to "normal" in that most of the patches are drivers (mainly GPU,
some crypto, some random small things - input layer, platform drivers
etc). There are misc small filesystem and arch updates too.

The appended shortlog is small enough that it's easy to just scroll
down and get a feel for what happened.

Pros and cons of Linux

tuxmachines.org - Sun, 01/07/2018 - 23:23

Obviously, as well as any other software or operating system, Linux has certain benefits and disadvantages. Most of them were already exposed. Linux might be rather disappointing for those who prefer playing games since not all of the are all available for this operating system's users. As well as for gamers, this system will be rather incomprehensible for newcomers due to a console that allows you to perform more complex operations, but demanding much more attention and skills to master it.

However, the major advantage for all the users is the security of this system. You may forget about viruses and antiviruses once and for all. Moreover, Linux is far less overloaded comparing with Windows, so it works much faster.

Plasma5 + Kernel 4.14 + mtp

LinuxQuestions.org latest posts - Sun, 01/07/2018 - 21:34
Is anyone here having the same problems? I just updated my desktop to -current with self-compiled packages of KDE/plasma and i can't mount my mobile phone via mtp anymore.

I have tested latest LTS-4.4.x kernel and everything is fine.

I found a bug report here but the affected kernel versions are different to -current/4.14.11.

4.4 fixed it for me, i'll try some older 4.14 releases soon... just interested if other do have similar issues.

su command on cloned system doesn't work

LinuxQuestions.org latest posts - Sun, 01/07/2018 - 19:50
I had an empty partition at my drive and decided to clone my system to that partition.
Well, I just copied entire the root filesystem (excluding tmp, proc, sys and dev directories content), tweaked grub.cfg, /etc/fstab and rebooted into freshly cloned system.
All seems OK except one thing: I can't run su, kdesu and sudo commands. In fact I can do it, but I getting "Authentication failed" message when I entering root password. It occurs both in GUI and CLI.

However, if I (being switched into CLI with Alt+Ctrl+F1) logging in as root directly (without su) I can log into root account.

Can anyone explaine what's going on?

Updating to Slackware 14.2 now KDE has no internet

LinuxQuestions.org latest posts - Sun, 01/07/2018 - 19:48
I just upgraded to Slackware 14.2 and while I have internet from the login terminal (slackpkg and lynx have internet) and the boot shows both IPv6 and IPv4 addresses, once I go into KDE, there's no internet and apparently no way to activate it. I'm using a wired connection and it really should be possible to connect in KDE since the connection is there both before and after using X windows. I'm flummoxed and totally clueless about where to look.

Cannot launch any of my snaps. 'Permission denied' error.

Hi.

I get this for all my snaps.

Example:

Code: snap run cool-retro-term Code: cannot bind mount namespace group directory over itself: Permission denied I simply installed snapd in Debian 9 Stable. Should I do more?

I previously had snapd and uninstalled a while back it but want to try them again do reinstalled it yesterday - perhaps that's something to do with it?

howto build latest kernel? been dragging my feet on this

LinuxQuestions.org latest posts - Sun, 01/07/2018 - 18:15
Following
https://docs.slackware.com/howtos:ha...m:raspberrypi3

says can use SARPi Project to install 14.2,-current

I did.

Does the following build slackwarearm kernel NOT rpi-update flavored one?

then says:
I recommend to build your own Linux kernel packages because the kernel you are
running does not match with the installed Slackware ARM packages

https://www.raspberrypi.org/document...el/building.md

Next get the sources, which will take some time:
Code: git clone --depth=1 https://github.com/raspberrypi/linux RASPBERRY PI 2, PI 3, AND COMPUTE MODULE 3 DEFAULT BUILD CONFIGURATION
Code: cd linux
KERNEL=kernel7
make bcm2709_defconfig Build and install the kernel, modules, and Device Tree blobs; this step takes a long time:
Code: make -j4 zImage modules dtbs
sudo make modules_install
sudo cp arch/arm/boot/dts/*.dtb /boot/
sudo cp arch/arm/boot/dts/overlays/*.dtb* /boot/overlays/
sudo cp arch/arm/boot/dts/overlays/README /boot/overlays/
sudo cp arch/arm/boot/zImage /boot/$KERNEL.img
Is that all there is to it? THANKS!

RadioShack DualShock PSX to USB adapter 26-304

LinuxQuestions.org latest posts - Sun, 01/07/2018 - 17:24
Hello, I am trying to cobble together some information on this obscure dongle and whether anyone has gotten this to work on a Linux system. I'm running the latest Ubuntu MATE, C2D E7300, 8GB.

It's an adapter for a DualShock controller to USB, originally supported under Win98 and XP, and the model # was 26-304. Currently lsusb does not recognize this adapter under any of the USB ports on my system. Anyone out there gotten this working?

Don't forget to vote :)

Leftovers: Containers in Research, Opera, KDE Software, Thunderbolt 3, Android and Chrome OS

tuxmachines.org - Sun, 01/07/2018 - 17:04
  • Containers in Research

    Last week, I attended the Docker Containers for Reproducible Research Workshop hosted by the Software Sustainability Institute. Many talks were addressing how containers can be used in a high performance computing (HPC) environment. Since running the Docker daemon requires root privileges, most administrators are reluctant to allow users running Docker containers in a HPC environment. This issue as been addressed by Singularity, which is an alternative conterization technology that does not require root privileges. The nice thing is that Singularity allows importing existing Docker images, which allows you creating a Singularity container from anything that is on Docker Hub. Although I only used Docker so far, Singularity sounds like a nice technology I would like to explore in the future.

  • Fedora 28 Aiming For Secure Thunderbolt 3 Support

    If Fedora developers are successful, Fedora 28 will feature secure and properly supported Thunderbolt 3 device handling out-of-the-box.

    Long story short, Fedora 28 will hopefully be featuring Red Hat's Bolt project for dealing with modern Thunderbolt devices. With Thunderbolt allowing for direct access to the PCI Express bus, it opens the system up to DMA attacks and other vulnerabilities. But under Thunderbolt 3 is support for security levels by which devices can be restricted to only DisplayPort acess, user authorization of devices, and secure access. The Linux kernel changes for dealing with Thunderbolt 3 is in place but the user-space portion is not.

  • This is the new Acer Chromebook 11

    Many people diss Chromebooks because they simply don't understand them. No, Chrome OS -- the operating system that powers these laptops -- is not just a glorified web browser. Actually, the OS is a full Linux distribution that is both extremely secure and easy to use. True, they can be deficient for some tasks, such as video editing and hardcore gaming, but let's be honest -- not everyone has those needs. If everything you do is in a browser -- email, web surfing, social media, YouTube, Netflix, etc. -- there is no reason to run Windows and open yourself up to malware and other bad things. Hell, Chromebooks even have Microsoft Office support these days!

[SOLVED] Solution for 12/15 Steam Linux client games not loading

LinuxQuestions.org latest posts - Sun, 01/07/2018 - 17:02
If you're having problems (Slackware 14.2, multilib, haven't tried current) with games not loading after the 12/15 Steam release, in /usr/bin/steam, comment out "export LD_LIBRARY_PATH=/usr/lib/seamonkey," and games should launch again.

If you're getting "data folder not found" on Unity games, that appears to be a different issue. Install the game to someplace not .local/share/Steam, and it should work again. I have no idea if it's related to the 12/15 release or not. With the holidays and a dying video card, I didn't use Steam in December.

  • Germany vs Elsevier: universities win temporary journal access after refusing to pay fees

    The Dutch publishing giant Elsevier has granted uninterrupted access to its paywalled journals for researchers at around 200 German universities and research institutes that had refused to renew their individual subscriptions at the end of 2017.

    The institutions had formed a consortium to negotiate a nationwide licence with the publisher. They sought a collective deal that would give most scientists in Germany full online access to about 2,500 journals at about half the price that individual libraries have paid in the past. But talks broke down and, by the end of 2017, no deal had been agreed. Elsevier now says that it will allow the country’s scientists to access its paywalled journals without a contract until a national agreement is hammered out.
