    Game in Linux CLI

    Posted: 28 Feb 2020 11:25 AM PST

    I'm trying to remember the name of a game I played years ago so that I can revisit it. It was game where you had to find the password and then use that password to get to the next level. Finding the password required using increasingly complex Linux commands to find where the password was hidden.

    I remember you would start by connecting to the IP in your shell and you would be in a directory having and just had to start looking. Any ideas what this was called?

    Deal boot MX Linux and Lakka, can /home be accessed with Lakka?

    Posted: 28 Feb 2020 02:36 AM PST

    I have MX Linux and I am having issues with gamepads and setting them up with RetroArch, so I'm giving up and going to partition my ssd (20gb or so) for Lakka. My question is; can I access the /home directory that's set up with MX Linux (on a separate 1tb drive formetted to ext4) to access my roms?

    Compatibility with a Windows monitoring app?

    Posted: 28 Feb 2020 09:07 AM PST

    I'm looking to make the switch to Linux (probably Manjaro specifically), but there's one thing holding me back.

    I use this monitoring app, and it doesn't support Linux. I really like the way this app works, other apps of the same type have all had their issues, and this one just does what it's supposed to, so I'm hesitant to switch to another app after finally finding the one that works best for me.

    I know there are things you can do to run a windows app in Linux (wine, etc) but I wouldn't know how to go about it. I would also need it to run at startup in the background, and be running whenever the rest of the system is, hopefully without too much of a performance hit.

    Cron does not work

    Posted: 28 Feb 2020 10:07 AM PST

    I want to execute a script that automatically starts up google chrome. It is called "test.sh" and it is located in /home/andrias/test.sh. This is the script:

    #!/bin/bash google-chrome 

    I've run "chmod +x /home/andrias/test.sh" and have executed it successfully. I've added this to my crontab file:

    * * * * * /home/andrias/test.sh 

    Supposedly it should run every minute, but absolutely nothing happens. Any ideas why this does not work, or another option for doing the same? Thanks

    Desktop freezes when playing Steam game

    Posted: 28 Feb 2020 05:09 AM PST

    As the title says, whenever I'm playing a steam game, the desktop freezes. The clock in my "taskbar" doesnt update, I cant switch to another virtual desktop or even select Items on the desktop. However, when I'm playing a game via Lutris, the desktop is working as expected and I can even switch between desktops without a problem.

    I'm using POP OS with the Kubuntu / KDE desktop enviorment. Is there a workaround for this little problem?

    Thanks in advance.

    Wifi module failed to initialize

    Posted: 28 Feb 2020 10:55 AM PST

    Well here's the problem, I'm running a librebooted Thinkpad T400 with Parabola GNU/Linux-libre on it and wifi is refusing to work. I installed it just now making sure it is compatible with the deblobbed kernel, I was told it was AR5B97, but really it is RTL8723ae which happily is still supported. Network manager says "device not ready", i tried to use other networking utilities and they said "wlp2s0 initialisation failed" (netctl to be precise). Then I just checked the kernel ring buffer and this is the result:

    [~] > dmesg -w | grep rtl

    [ 12.956525] rtl8723ae: Using firmware /(DEBLOBBED)/

    [ 12.956584] rtl8723ae 0000:02:00.0: Direct firmware load for /(DEBLOBBED)/ failed with error -2

    [ 12.956586] rtlwifi: Selected firmware is not available

    [ 12.967112] ieee80211 phy0: Selected rate control algorithm 'rtl_rc'

    [ 12.967522] rtlwifi: rtlwifi: wireless switch is on

    [ 13.452639] rtl8723ae 0000:02:00.0 wlp2s0: renamed from wlan0

    To say the least, I'm stumped. And yes the card is working, tried an arch live iso, just typed wifi-menu and it worked.

    Netdata release v1.20!

    Posted: 28 Feb 2020 10:48 AM PST

    Hey all,

    Our first major release of 2020 comes with an alpha version of our new eBPF collector. eBPF (extended Berkeley Packet Filter) is a virtual bytecode machine, built directly into the Linux kernel, that you can use for advanced monitoring and tracing. Check out the full release notes and our blog post for full details.

    With this release, the eBPF collector monitors system calls inside your kernel to help you understand and visualize the behavior of your file descriptors, virtual file system (VFS) actions, and process/thread interactions. You can already use it for debugging applications and better understanding how the Linux kernel handles I/O and process management.

    The eBPF collector is in a technical preview, and doesn't come enabled out of the box. If you'd like to learn more about_why_ eBPF metrics are such an important addition to Netdata, see our blog post: Linux eBPF monitoring with Netdata. When you're ready to get started, enable the
    eBPF collector by following the steps in our documentation.

    This release also introduces host labels, a powerful new way of organizing your Netdata-monitored systems. Netdata automatically creates a handful of labels for essential information, but you can supplement the defaults by segmenting your systems based on their location, purpose, operating system, or even when they went live.

    You can use host labels to create alarms that apply only to systems with specific labels, or apply labels to metrics you archive to other databases with our exporting engine. Because labels are streamed from slave to master systems, you can now find critical information about your entire infrastructure directly from the master system.

    Our host labels tutorial will walk you through creating your first host labels and putting them to use in Netdata's other features.

    Finally, we introduced a new CockroachDB collector. Because we use CockroachDB internally, we wanted a better way of keeping tabs on the health and performance of our databases. Given how popular CockroachDB is right now, we know we're not alone, and are excited to share this collector with our community. See our tutorial on monitoring CockroachDB metrics for set-up details.

    We also added a new squid access log collector that parses and visualizes requests, bandwidth, responses, and much more. Our apps.plugin collector has new and improved way of processing groups together, and our cgroups collector is better at LXC (Linux
    container) monitoring.

    Speaking of collectors, we revamped our collectors documentation to simplify how users learn about metrics collection. You can now view a collectors quickstart to learn the process of enabling collectors and monitoring more applications and services with Netdata, and see everything Netdata collects in our supported collectors list.

    Breaking Changes

    • Removed deprecated bash
      collectors apache
      , cpu_apps
      , cpufreq
      , exim
      , hddtemp
      , load_average
      , mem_apps
      , mysql
      , nginx
      , phpfpm
      , postfix
      , squid
      , tomcat
      If you were still using one of these collectors with custom configurations, you can find the new collector that replaces it in the supported collectors list.
    • Modified the Netdata updater to prevent unnecessary updates right after installation and to avoid updates via local tarballs #7939. These changes introduced a critical bug to the updater, which was fixed via #8057 #8076 and #8028. See issue 8056 if your Netdata is stuck on v1.19.0-432.

    Improvements

    Host Labels

    • Added support for host labels
    • Improved the monitored system information detection. Added CPU freq & cores, RAM and disk space
    • Started distinguishing the monitored system's (host) OS/Kernel etc. from those of the docker container's

    Issues outputting command output to text file

    Linux Command Help rm -r ~/temp

    Posted: 28 Feb 2020 01:33 PM PST

    What does the command rm -r ~/temp do?

    rm is remove

    -r is recursive delete (meaning it deletes all files)

    ~ is home directory

    /temp is temporary directory

    So all together does this mean delete all files from the temporary directory?

    Is there anywhere I can learn complex linux commands?

    Installing PHP on a shared server

    Posted: 28 Feb 2020 01:01 PM PST

    I'm not really familiar with Ubuntu, I've attempted installing PHP 7.2.5 (or any version above 7.1.3) on a Shared Server and have failed multiple times. The problem I'm having is that I cant use any Sudo commands as its a shared server and accessing root is pretty much a no-go, so I'm having to install it within my home directory which is painstakingly difficult for myself as I'm not Linux-Savvy as of yet. I also need Nginx to talk to it aswell. Can anyone help me out with installing and configuring Nginx and PHP, I would appreciate it massively and i'm sure it will be a doddle for anyone with experience.

    What's the difference between /mnt and /run/media?

    Posted: 28 Feb 2020 12:48 PM PST

    So normally when I've messed around with Linux in the past I've only ever had a root directory because all of my other drives were occupied by NTFS file systems. Since I didn't daily drive Linux I didn't have much of a need for any secondary disks. Now I use Linux a lot more and I decided to dedicate one of my drives for storing games and stuff on Linux. Problem is I'm still kinda noob at Linux and I'm somewhat confused about drive mounting. Anyways when I format a drive in gnome disks as GPT and put an ext4 filesystem on it the default mounting options sometimes place it in /mnt/XXXX or /run/media/XXXX as an example. I kind of want the drive to always be available like how drives are in Windows once you assign a drive letter to them and don't remove them when windows is booted. I had a drive mounted at /mnt/XXXX and somehow Steam lost sight of the path. I'm not sure if Steam loaded up a service or something before the drive was mounted and just assumed it wasn't there anymore or if I mounted it incorrectly. I've also had drives mount under /run/media/XXXX but I'm not entirely sure what the difference is or if it matters. Also I'm a bit confused because it would seem as if /etc/fstab can be bypassed with gnome disks when changing the mounting options. I have a few items under /mnt that shouldn't be there or point to nowhere.

    Anyone wanna leave some advice?

    Migrating to Linux for the first time

    Posted: 28 Feb 2020 12:05 PM PST

    Hello community,

    I've been researching to join the Linux OS community and stumbled upon Manjaro. So far it looks great and I am planning on migrating to Manjaro permanently. I've selected to Gnome for now.

    Before doing so I want to know what I might encounter along the way.Here are some points for which I'd like a bit of assistance.

    • Are there are any hardware limitations which I should take into consideration?
    • I am planning on buying a new sdd for the OS. Which brands/models would fit best the purpose?
    • How do I actually boot/install Gnome Manjaro OS?
    • What software/settings do I need to make with the installation and right after?
    • Do I actually get hardware drivers automatically like in Win10? If not, how do I download/update them?

    A bit of info about me. Currently, I am using my pc for gaming, browsing, movies, email. Any software tips and recommendations are welcome.My specs are i7-6300K, 16GB RAM, GTX970.

    Thank you!

    Need help to figure out the distribution...

    Posted: 28 Feb 2020 11:56 AM PST

    I need help to pick a linux distro....

    My windows 7 is giving up on me and is trying to force an update.... what it has yet to learn is that we will roll Windows 7, but Linux will be rolling in.

    My old laptop has been acting up, so it became a smartbox for the living room TV.

    I need help because my project may evolve and I'd like a direction to avoid dead ends....

    My livinroom TV is the current laptop screen... Windows is too heavy and wants out. Linux is lighter and could improove speed and lifelenght Ubuntu has a neet rocket doc function I'd like for runnin my Tv... I dont need the "Windows like" function, I just want youtube, crave, hulu, cbc..... Worried I cant find the LinuxLight I used in school last century.... ArchLinux looks like i could eventually achieve something someday.... I like the RaspberryPi, and could get one if the need to dump the laptop arise.

    So sorry this is allover the place. I'm willing to spend the weekend on introduction videos and forums, i would like to have a pro's advice on what distro to invest time into...

    Is there a way to require a 'sudo' for use of an alias?

    Posted: 28 Feb 2020 09:45 AM PST

    This is more of a bash question than a Linux one, but I don't know where else to ask and am having trouble Googling for an answer.

    I want to make an alias for opening a folder, but require a 'sudo' to use it. I would guess there might be a way to do this in my .bashrc file, but can't figure out how. Any tips?

    Tried fixing touchpad on Zenbook, now touchpad, bluetooth mouse, and wired mouse no longer work, and cursor is stuck.

    Posted: 28 Feb 2020 05:59 AM PST

    Hi everyone,

     

    I had a quick question that I was hoping someone could answer here.

     

    The touchpad had not been working on my ASUS Zenbook UX431FN-IH74, and I was looking for solutions to fix it. I'm running Ubuntu 18.04 on my computer for reference.

     

    I found this thread:

     

    https://www.reddit.com/r/linux4noobs/comments/9j7zik/ubuntu_1804_god_awful_touchpad_support/

     

    and installed what was suggested in the first comment:

     

    sudo apt install xserver-xorg-input-synaptics

     

    I restarted my system and was able to login, but once I do, the cursor is stuck in the bottom right corner of the screen and neither the touchpad works, my Bluetooth mouse, or the wired mouse I tried plugging in. Pressing ctrl + alt + t does not bring up the terminal either.

     

    I restarted again and accessed the terminal from the login screen and removed the package, but I still have the same issue after restarting.

     

    If anyone has any idea about what the problem could be I would much appreciate the help. I can provide more information if needed as well.

     

    Thank you!
