[SOLVED] Upgrade to 14.2 Keyboard and X Issues

LinuxQuestions.org latest posts - Sat, 01/06/2018 - 21:39
Greetings and thank you for seeking info or to help. I'm still working on this but as some behavior is quite odd to me I will be checking this thread and any assistance is greatly appreciated.

OK - Setting - I run two versions of Slackware, one main that is Multilib 14.2 with a custom 4.14.12 kernel and another for DAW work that was 32bit 14.0 with a custom 3.12.0 kernel. They have run fine for a very long time. However I decided to upgrade 14.0 32 bit to 14.2 32 bit for several reasons once I discovered I could successfully run it alsa-only. This thread is about that process.

I did the upgrades incrementally, first to 14.1 32 bit which ran fine but I still needed a newer glibc so, after insuring everything worked normally as 14.1 I used the same recommended process as per slackdocs to upgrade to 14.2 32 bit.

Everything seemed to progress nicely and I was careful to keep both the hugesmp kernel from 14.1 as well as the original (to me) custom kernel from 14.0, both of which were successful. I also used the custom kernels config to build a new 4.14.12 kernel using make oldconfig, checked it with make menuconfig, and built and installed it as an option hopefully to become the next Main. I've had problems with each of these so I subsequently also enabled the newer default hugesmp kernel from the 14.2 32bit install disk.

I can boot to runlevel 3 with all of those kernels but suffer 2 or 3 problems.

1) with my custom 4.14.12 kernel, I installed the latest nvidia proprietary driver that had worked both as 14.0 and 14.1. However with the 14.2 install X fails to start whether I try my usual "kdm" (it just sits there) or "startkde" or "startx" whether as root or user. I get an error saying $DISPLAY is not set but I'm using the exact same "/etc/X111/xorg.conf" that worked fine on both 14.0 and 14.1. I also get a message that libxshmfence does not exist which is particularly odd since it does but seems to be the 1.0.0 version from 14.1 not 1.2.0 (iirc) from 14.2. Unless I made a typo that had extremely few consequences, at least in error messages during the upgrade to 14.2, I did type
Code: upgradepkg --install-new /root/slackware/*/*.t?z This not starting X or finding $DISPLAY with which to start it is the ultimate issue.

2) A somewhat lesser, but way more troublesome problem rather boggles my mind. Whether I use the included 14.2 huge-smp kernel or even the install disk's hugesmp.s, I get to a CLI login but my wireless keyboard, which works fine during other installs and all previous slackware versions and kernels but is inoperable with the included huge-smp kernel(s). FWIW the original 14.0 custom kernel v3.12.0 and the new custom 4.14.12 both have keyboard working normally.

I realize this may seem daunting with so many variables but I would appreciate any kind soul's input on either or both issues. FWIW After a long night of troubleshooting I can't ATM recall if I ever tried to reach X from the custom 3.12.0 kernel from 14.0 out of desperation but I do recall considering that to be possibly risky given the considerable difference in glibc that compiled it, but if that isn't as risky as I imagine, I'd even try that.

I generally don't like to ask for help on such deep level issues since troubleshooting such is like a great crash course where I always learn a lot, but I just woke up and feel a bit perplexed, especially over the damned keyboard issue even though that's only an interim step. I mean, how is that even possible?

Sorry if this is a rambling mess but I will get back and clear it up soon. Thanks again.

it works great im really happy as the end users need to download the papercut client via the smb share (\\CUPS\client), once they download that they then add the printer via -


but then it asks the end user for the driver to install, is there a way to automatically dish it out so the end user does nothing as they arnt tech savy shall we say

Synaptic And Other Things Not Working in a fresh install of Debian 9

LinuxQuestions.org latest posts - Sat, 01/06/2018 - 19:04
After a fresh installation of Debian 9 things stopped working properly and I think that libraries are missing. Notice I said 'think'

At one point Synaptic launched w/o root privileges.
Now, when booted into the XFCE DE Synaptic will only launch by executing 'synaptic' as root in the konsole.

Synaptic launches w/o any problems while booted into the Mate DE.

LightDM launches in the Mate DE but not in the KDE DE. Also I don't have lightDM-KDE-greeter in the KDE DE.

I looked in Synaptic to see what is installed. Here's the list:

Code: lightdm
liblightdm-gobject-1-0 It looks like the API's are missing libraries and this is why Synaptic and other things are either crashing or not launching at all.

How can I find out what libraries are missing and what libraries to install?

OR is this a front end issue? How do I fix this?

Here's the other thread where things aren't going well with this install.


BTW the SHA for the Debian 9 .iso checked out fine.

GPG key trouble LM18.3

LinuxQuestions.org latest posts - Sat, 01/06/2018 - 18:33
Recently installed LM18.3 and I have one pub key and one secret key for my keyring.

I opened nemo-seahorse and imported the 2 keys, they were accepted. I have one gpg file that I need to decrypt easily IE: not using the terminal... but when I click or right click on that file I get a list of things to use to open it,none of which are applicable... notmally I'd get a window to type in a passphrase as before in Mint 17.3.

Is there an addon program that I need to make this work in 18.3? I don't recall doing anything special in 17.3 so this puzzles me,

The keys are not on a keyserver they are just for my own use.

Thanks a lot.


chromium browser on mint18.2

LinuxQuestions.org latest posts - Sat, 01/06/2018 - 18:18
Having a few issues with chromium (I think) which seem to build up over time
but to cut a long story short (and for different reasons) I noticed - in Code: ps -auxwww - the cmdline for chromium. I've added it at the end because it's 1903 bytes long.

Basically there's a param switch which seems odd to me :

Code: --content-image-texture-target It basically seems to define 7 x 18 instances of a code - 3553. What is this and why is such a structure being passed on the cmd? Seems a bit inelegant at best and makes me wonder if I have a problem with my installation. I've been trying to work out what might require something of dimensions 7x18 all with the same code in the first place(??).

Watch movie and now display was stretched

LinuxQuestions.org latest posts - Sat, 01/06/2018 - 17:58
We used my Laptop to watch a movie the other night. A vga cable connects it to the tv. Afterwards the display on my monitor was stretched too wide. I tried messing with fonts, icon size, conky settings, cairo-dock settings, chromium settings all in an effort to return my display to normal

Was chatting with my son about it and he asked if the cable was still attached. It was.
Disconnect cable, logout, restart x and now is OK.

Is there some other way to gain control?

Can see my NFS share but not the files/folders inside it

LinuxQuestions.org latest posts - Sat, 01/06/2018 - 17:30
On Linux Mint 18.3, I have a folder shared out via NFS with lots of files/folders in it. The share appears to be setup correctly and I can mount it from my Antergos box but when I go into it from Antergos, it's empty.

I'm sure it's a permission issue of some kind or how I'm sharing it out. Any tips?

In my /etc/exports file on Mint, I have tried the following:

/mnt/md0/data *(ro,all_squash,insecure)

That last one.... I'm sure the anonuid and anongid is wrong for me..... somebody posted it in a forum and since this was my 3rd attempt at trying to make this work, I just left all the default stuff in. Everything in that folder is drwxrwxrwx and when I type showmount -e, I get:

Export list for server-pc:

Side question. A few weeks back, I was experimenting with a Synology box and mapped an NFS share on it from my Mint box and when I type showmount (no switches) I get:

Hosts on server-pc:

I have no idea where to go to nuke that old entry. (I'm almost positive that was the IP address of my Synology box that is no longer in my house.)

  • AMD Did NOT Disable Branch Prediction With A Zen Microcode Update

    With the plethora of software security updates coming out over the past few days in the wake of the Meltdown and Spectre disclosure, released by SUSE was a Family 17h "Zen" CPU microcode update that we have yet to see elsewhere... It claims to disables branch prediction, but I've confirmed with AMD that is not actually the case.

    AMD did post a processor security notice where they noted their hardware was not vulnerable to variant threee / rogue data cache load, for the "branch target injection" variant that there was "near zero risk" for exploiting, and with the bounds check bypass it would be resolved by software/OS updates.

  • Spectre and Meltdown Attacks Against Microprocessors

    "Throw it away and buy a new one" is ridiculous security advice, but it's what US-CERT recommends. It is also unworkable. The problem is that there isn't anything to buy that isn't vulnerable. Pretty much every major processor made in the past 20 years is vulnerable to some flavor of these vulnerabilities. Patching against Meltdown can degrade performance by almost a third. And there's no patch for Spectre; the microprocessors have to be redesigned to prevent the attack, and that will take years. (Here's a running list of who's patched what.)

  • OpenBSD & FreeBSD Are Still Formulating Kernel Plans To Address Meltdown+Spectre

    On Friday DragonFlyBSD's Matthew Dillon already landed his DragonFly kernel fixes for the Meltdown vulnerability affecting Intel CPUs. But what about the other BSDs?

    As outlined in that article yesterday, DragonFlyBSD founder Matthew Dillon quickly worked through better kernel/user separation with their code to address the Intel CPU bug. Similar to Linux, the DragonFlyBSD fix should cause minimal to small CPU performance impact for most workloads while system call heavy / interrupt-heavy workloads (like I/O and databases) could see more significant drops.

  • Retpoline v5 Published For Fending Off Spectre Branch Target Injection

    David Woodhouse of Amazon has sent out the latest quickly-revising patches for introducing the "Retpoline" functionality to the Linux kernel for mitigating the Spectre "variant 2" attack.

    Retpoline v5 is the latest as of Saturday morning as the ongoing effort for avoiding speculative indirect calls within the Linux kernel for preventing a branch target injection style attack. These 200+ lines of kernel code paired with the GCC Retpoline patches are able to address vulnerable indirect branches in the Linux kernel.

    The Retpoline approach is said to only have up to a ~1.5% performance hit when patched... I hope this weekend to get around to trying these kernel and GCC patches on some of my systems for looking at the performance impact in our commonly benchmarked workloads. The Retpoline work is separate from the KPTI page table isolation work for addressing the Intel CPU Meltdown issue.

    We have received *no* non-public information. I've seen posts elsewhere by other *BSD people implying that they receive little or no prior warning, so I have no reason to believe this was specific to OpenBSD and/or our philosophy. Personally, I do find it....amusing? that public announcements were moved up after the issue was deduced from development discussions and commits to a different open source OS project. Aren't we all glad that this was under embargo and strongly believe in the future value of embargoes?

Latest of LWN (Paywall Expired)

  • Python 3, ASCII, and UTF-8

    The dreaded UnicodeDecodeError exception is one of the signature "features" of Python 3. It is raised when the language encounters a byte sequence that it cannot decode into a string; strictly treating strings differently from arrays of byte values was something that came with Python 3. Two Python Enhancement Proposals (PEPs) bound for Python 3.7 look toward reducing those errors (and the related UnicodeEncodeError) for environments where they are prevalent—and often unexpected.

    Two related problems are being addressed by PEP 538 ("Coercing the legacy C locale to a UTF-8 based locale") and PEP 540 ("Add a new UTF-8 Mode"). The problems stem from the fact that locales are often incorrectly specified and that the default locale (the "POSIX" or "C" locale) specifies an ASCII encoding, which is often not what users actually want. Over time, more and more programs and developers are using UTF-8 and are expecting things to "just work".

  • Shrinking the kernel with link-time garbage collection

    One of the keys to fitting the Linux kernel into a small system is to remove any code that is not needed. The kernel's configuration system allows that to be done on a large scale, but it still results in the building of a kernel containing many smaller chunks of unused code and data. With a bit of work, though, the compiler and linker can be made to work together to garbage-collect much of that unused code and recover the wasted space for more important uses.
    This is the first article of a series discussing various methods of reducing the si

  • The current state of kernel page-table isolation

    At the end of October, the KAISER patch set was unveiled; this work separates the page tables used by the kernel from those belonging to user space in an attempt to address x86 processor bugs that can disclose the layout of the kernel to an attacker. Those patches have seen significant work in the weeks since their debut, but they appear to be approaching a final state. It seems like an appropriate time for another look.
    This work has since been renamed to "kernel page-table isolation" or KPTI, but the objective remains the same: split the page tables, which are currently shared between user and kernel space, into two sets of tables, one for each side. This is a fundamental change to how the kernel's memory management works and is the sort of thing that one would ordinarily expect to see debated for years, especially given its associated performance impact. KPTI remains on the fast track, though. A set of preparatory patches was merged into the mainline after the 4.15-rc4 release — when only important fixes would ordinarily be allowed — and the rest seems destined for the 4.16 merge window. Many of the core kernel developers have clearly put a lot of time into this work, and Linus Torvalds is expecting it to be backported to the long-term stable kernels.

    KPTI, in other words, has all the markings of a security patch being readied under pressure from a deadline. Just in case there are any smug ARM-based readers out there, it's worth noting that there is an equivalent patch set for arm64 in the works.

  • Containers without Docker at Red Hat

    The Docker (now Moby) project has done a lot to popularize containers in recent years. Along the way, though, it has generated concerns about its concentration of functionality into a single, monolithic system under the control of a single daemon running with root privileges: dockerd. Those concerns were reflected in a talk by Dan Walsh, head of the container team at Red Hat, at KubeCon + CloudNativeCon. Walsh spoke about the work the container team is doing to replace Docker with a set of smaller, interoperable components. His rallying cry is "no big fat daemons" as he finds them to be contrary to the venerated Unix philosophy.

  • Demystifying container runtimes

    As we briefly mentioned in our overview article about KubeCon + CloudNativeCon, there are multiple container "runtimes", which are programs that can create and execute containers that are typically fetched from online images. That space is slowly reaching maturity both in terms of standards and implementation: Docker's containerd 1.0 was released during KubeCon, CRI-O 1.0 was released a few months ago, and rkt is also still in the game. With all of those runtimes, it may be a confusing time for those looking at deploying their own container-based system or Kubernetes cluster from scratch. This article will try to explain what container runtimes are, what they do, how they compare with each other, and how to choose the right one. It also provides a primer on container specifications and standards.

  • HarfBuzz brings professional typography to the desktop

    By their nature, low-level libraries go mostly unnoticed by users and even some programmers. Usually, they are only noticed when something goes wrong. However, HarfBuzz deserves to be an exception. Not only does the adoption of HarfBuzz mean that free software's ability to convert Unicode characters to a font's specific glyphs is as advanced as any proprietary equivalent, but its increasing use means that professional typography can now be done from the Linux desktop as easily as at a print shop.

    "HarfBuzz" is a transliteration of the Persian for "open type." Partly, the name reflects that it is designed for use with OpenType, the dominant format for font files. Equally, though, it reflects the fact that the library's beginnings lie in the wish of Behdad Esfahbod, HarfBuzz's lead developer, to render Persian texts correctly on a computer.

    "I grew up in a print shop," Esfahbod explained during a telephone interview. "My father was a printer, and his father was a printer. When I was nine, they got a PC, so my brother and I started learning programming on it." In university, Esfahbod tried to add support for Unicode, the industry standard for encoding text, to Microsoft Explorer 5. "We wanted to support Persian on the web," he said. "But the rendering was so bad, and we couldn't fix that, so we started hacking on Mozilla, which back then was Netscape."

    Esfahbod's early interest in rendering Persian was the start of a fifteen-year effort to bring professional typography to every Unicode-supported script (writing system). It was an effort that led through working on the GNOME desktop for Red Hat to working on Firefox development at Mozilla and Chrome development at Google, with Esfahbod always moving on amiably to wherever he could devote the most time to perfecting HarfBuzz. The first general release was reached in 2015, and Esfahbod continues to work on related font technologies to this day.
