Plasma5 + Kernel 4.14 + mtp

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

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

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.

Sun, 01/07/2018 - 19:12

I get this for all my snaps.


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?

Linux and Assembly

Sun, 01/07/2018 - 19:10
I am a retired COBOL programmer, stuck in the Windows World. I recently decided to learn Assembly language, and I want to bypass the memory model issues by going to a 64 bit assembler. I don't yet have Linux on my computer, so I am interested in recommendations for distribution type, hopefully one with YASM included.

howto build latest kernel? been dragging my feet on this

Sun, 01/07/2018 - 18:15

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

Next get the sources, which will take some time:
Code: cd linux
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

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 :)

LXer: A school in India defies the traditional education model

Located in a sleepy village just two hours away from the bustling metropolis of Mumbai is a school that defies traditional educational models by collaboratively owning, building, and sharing knowledge and technology. The school uses only open source software and hardware in its approach to learning, and takes pride in the fact that none of its students have used or even seen proprietary software, including the ubiquitous Windows operating system.


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

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.

Newly Installed Linux Mint 18.3 Sylvia Cinnamon Edition Won't Boot

Sun, 01/07/2018 - 15:23
Hi all, first time poster here.

I just installed Linux on my laptop as a replacement to Windows 8.1, which was running slowly. The steps I used to install it were fully formatting and wiping my hard drive using Parted Magic and then installing Linux Mint 18.3 via a bootable USB. As far as I can tell, the install was successful, but when I try to boot from the hard drive I get a message "checking media presence, no media present."

I would really appreciate any help anyone could give me to get this working. I'm sure there's a lot more info I could provide that would be helpful, but I'm a true newbie, so could really use some guidance. Thanks in advance!

LXer: Pros and cons of Linux

Published at LXer:

Windows today beats almost all the markets thanks to its simplicity and large number of programs and games in a free access. We are used to Windows since there are no compatible systems like Windows. However, it is not true. Unfortunately, most people are creatures of habit that's why it will take years for the Linux to take its place among the users.


dont want to see volumes in file manager

Sun, 01/07/2018 - 14:52

do either of you know a way to hide the volumes in the file manager?
The Deepin file manager shows all the volumes I CAN connect to, I do this via fstab and don't need the view, and it's only confusing.
Nautilus File Manager also displays the folders in which I have included the partitions twice, i. e. normally in the overview at the top left and then again at the bottom, as mounted.
I mount like this..
: > //ip/share/documents /home/tom/documents cifs.....


hmm...cannot add pictures from pasteboard?

I think my best piece is Subtle Erotica which is in the album Artistic Cause.

Critics are welcome. Just don't be so hard. :D

I am not finding anything useful or helpful anymore at Linux Questions. So I think I am done. I am signed up for too many different forums as it is. So I am out of here. Good luck all and remember to have fun.
