      Most recent update is here.


      The Tildes community has been amazing and patient with me as a new and uninformed Linux user, and I'm greatly appreciative of that. I return to you today with yet another request.


      Hardware

      System76 Oryx Pro
      Distro: Pop!_OS 19.10


      Issue #1 (mission critical)

      Brother MFC-L2750DW

      I have a Brother printer/scanner for which I have installed the drivers using the .deb file provided on the Brother site. It's connected via USB. Printing works fine; scanning does not. My husband and I both need the ability to scan for our jobs, so this issue is pretty important to us.

      I am using the program Document Scanner (I believe it's one of the GNOME default programs?). When I open the program it says "Searching for Scanners" and then recognizes my scanner, giving the model number and says it's "Ready to Scan". Whenever I attempt to scan, however, whether from the ADF or the flatbed, it says "Unable to connect to scanner". I am not sure how to proceed, and any guidance on this would be greatly appreciated!


      Issue #2 (optional)

      Hyperkin Duke Wired Xbox Controller

      This is an optional issue and not at all one that needs to be solved by any means. A while back my husband got me this because it's my absolute favorite controller of all time (I know, scoff all you want!). It worked fine in Windows, but now that I've shifted over to Linux it has been sitting and gathering dust.

      When I plug it in the controller rumbles briefly (which it also did on Windows), but other than that does nothing. No input is accepted. If it's easy to get this up and running in Linux, I'd love to be able to use it, but if it's not that's totally fine. I have another controller I can use, and again, none of this is essential to my work. I just figured since I was asking for help I'd throw this in here too.


      If you need any additional information or need me to try any specific things, let me know!

    2. [SOLVED] Tech support request: Recovering from hard crashes in Linux

      EDIT: Latest update


      This is something so rudimentary that I'm a little embarrassed to ask, but I've also tried looking around online to no avail. One of the hard parts about being a Linux newbie is that the amount of support material out there seems to differ based on distro, DE, and also time, so posts from even a year or two ago can be outdated or inapplicable.

      Here's my situation: I'm a newbie Linux user running Pop!_OS 19.10 with the GNOME desktop environment. Occasionally, games I'm playing will hard crash and lock up my system completely, leaving a still image of the game frozen on the screen indefinitely. The system stays there, completely unresponsive to seemingly any inputs. It doesn't happen often, but when it does it's almost always when I'm running a Windows game through Steam's Proton layer. I suspect it also might have something to do with graphics drivers, as I'll at times notice an uptick in frequency after certain updates, though that might just be me finding a suspicious pattern where none exists.

      Anyway, what I don't know how to do is gracefully exit or recover from these crashes. No keyboard shortcut seems to work, and I end up having to hold the power button on my computer until it abruptly shuts off. This seems to be the "worse case scenario" for handling it, so if there is a better way I should go about this, I'd love to know about it.


      EDIT: I really want to thank everyone for their help so far. My initial question has been answered, and for posterity's sake I'd like to post the solution here, to anyone who is searching around for this same issue and ends up in this thread:

      • Use CTRL+ALT+F3/F4/F5/F6 keys to access a terminal, where you can try to kill any offending processes and reboot if needed.
      • If that fails, use ALT+SYSRQ+R-E-I-S-U-B.

      With that out of the way, I've added more information about the crashes specifically to the thread, primarily here, and some people are helping me out with diagnosing the issue. This thread is now less about the proper way to deal with the crash than it is about trying to identify the cause of the crash and prevent it in the first place.

      So I bought this laptop mainly for web browsing, document editing, note taking and programming with perhaps light gaming although that's not something I've tried yet. So, really just for school work.

      Specifications

      Laptop Model : Acer Aspire 3 A315-42
      Laptop screen : 1080p IPS (with matte finish?)
      CPU : R5 3500U
      RAM : 8GB DDR4 (6GB available because of iGPU)
      Storage : 256GB SSD NVMe
      Wireless : Qualcomm Atheros QCA9377
      Wired : Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 (According to lspci)
      2x USB 2.0, 1x USB 3.0, 1x HDMI port, Audio jack, 1x RJ45 Ethernet port
      Battery : 36.7Wh

      Linux compatibility

      Everything worked out of the box, gotta modify TLP to not kill the touchpad and webcam. The touchpad seems to have a mind of its own when it comes to being detected, It seems to be a kernel bug, unsure what I'll do about it concretely but rebooting a couple of times makes it work. Nothing to install thanks to AMD's open source mesa drivers. Might need a kernel higher than 5.3 because of general Ryzen 3000 issues but I've not tried, it was already higher than that.

      Operating system tested

      Basically never touched Windows, directly installed Fedora 31 Silverblue.

      My Silverblue configuration is :

      ● ostree://fedora:fedora/31/x86_64/silverblue
                         Version: 31.20191213.0 (2019-12-13T00:42:11Z)

                                  powertop radeontop sysprof systemd-swap tilix tlp
      

      Kernel : 5.3.15
      Gnome : 3.34.1

      Body and Looks

      The screen back has metal, I believe it feels quite sturdy. The rest is reasonable feeling plastic. The material used just loves to imprint grease / fingers which kinda sucks - the keys being the exception thankfully. There was also stickers on the inside which well, are somewhat standard but I thought they were pretty obnoxious so I removed them.

      Typing experience

      It's nothing amazing but it's good enough. I'm not really knowledgeable on keyboards so that's as much as I can say on it, really.

      Performance

      Everything feels quite snappy but I don't game at all on this machine so I'm not pushing it too much other than while I'm compiling or doing other things. The temperature does go up to 75°C and the fans get a little loud but it's not that bad. It's mostly the bottom getting hot so it's not something you notice too much while typing. It also cold boots quite fast, in about 10-20seconds I want to say but I've not benchmarked that. It's my first computer with an SSD so there's that.

      Battery life

      I get about 5hours with tlp installed doing web browsing, some programming occasionally, listening to music on the speakers and chatting. Personally I was kind of expecting more from this considering it's an APU but it seems to be what other people are getting on similar setups so It'll do.

      Conclusion

      Overall, I'm pretty happy with this laptop considering how I bought it for 575$ on sale. I made this review mostly because I wasn't finding much information about this laptop on Linux and well, I don't know, I guess I felt like it. If you have any questions, ask up!

      Some more info about the PinePhone

      Pre-order page on the Pine Store

      The early adopter edition of the PinePhone is now available for pre-order. This batch is 3000 units, from what I know ~1000 are already sold. These units are currently being produced, and are planned to ship in December/January. Mass production of the consumer edition of the phone is planned to begin in March 2020.

      I just pre-ordered mine, is anyone else getting one? Any thoughts on the state of Linux smartphones, whether it's the PinePhone, Librem 5, or something else?

      I'm building my first desktop computer, and Linux is my operating system of choice.

      I know video cards sometimes can be a pain and wish to avoid any issues.

      Dollar-priced items are very expensive down here, and I don't require playing the latest games on the highest configurations. Just something to “put me on the map”, so to speak, so I can have a somewhat current machine that doesn't give me much trouble. Any suggestions?

      Because I'm in Brazil, highly specific brands that do not ship to my country are out of the question, and even the ones that ship usually cost more than I can pay due to currency exchange rate and shipping costs themselves. What are some universal brands and models that I can probably find on my location, that won't give me much trouble running Linux?

      I don't require playing games or top performance (4GB 8GB RAM, a nice/vibrant screeen and an i5 processor would be the minimum requirement. SSD would be nice, but for my budget it's a plus. Just something that is durable (with a good guarantee) and works reliably under Linux, especially when it comes to HDMI output, video graphics adapter support, booting from USB, hibernating, sleeping, power management etc.

      Thanks!

      Screenshot

      I posted a few days ago about a notes app I was working on called Notementum, and I'm happy to show you the first release (0.1.0). Installation instructions are available on the Github repo: https://github.com/IvanFon/notementum

      There's still lots of things I'd like to add, both big and small, and definitely a few bugs here and there, but I've been going for too long without sharing it, and I find it's best to release as early as you can to start getting feedback, and perfect it later.

      One things that's missing is documentation. I'd like to start on this soon, but I'm probably not going to share this anywhere other than Tildes just yet, so this comment will do for now :)

      Right now, the app only runs on Linux. I'd like to add Windows support, and it almost works, the problem is that WebKit2Gtk, the embedded web view I use to show note previews, doesn't support Windows. I'm going to explore some other options in the future, whether that's figuring out how to compile it, or allowing other preview methods (user's web browser, PDF, etc.).

      The app is also very much in alpha, so you shouldn't use this for anything important, there may be bugs that can cause you to lose some of your data. If you do use this for anything, make sure you backup your notes database.

      If you want to use it, here's a wall of text on usage:

      Usage

      The notes database is located at ~/.notes.db. When you launch the app, it'll load it, or automatically create it if it doesn't exist. I'd eventually like to allow choosing different locations, but it's hard coded for now.

      The interface is fairly simple. The leftmost sidebar displays a list of notebooks, and the "middlebar" displays a list of notes. Selecting a notebook will display the notes within it in the notes list. Selecting a note will open it in the editor, which is to the right.

      To create a new note, press Escape to focus on the searchbar above the notes list, and start typing a title. If no existing notes are found, press enter, and a note will be created with the title you entered.

      To rename a note, double-click on it in the notes list.

      The editor has a toolbar with 4 buttons, from left-to-right:

      • Toggle between editor and preview (shortcut: Ctrl+E)
      • Assign the current note's notebook
      • Add an attachment
      • Delete the current note

      The green circle all the way to the right turns into a loading indicator when you have unsaved changes. Once you stop typing for a few seconds, your changes will be saved, and it'll switch back into a green circle.

      Notebooks

      Notebooks aren't created directly, they're based on what notebooks your notes are assigned to. This means that, to create a notebook, assign it to a note. To delete a notebook, just delete all the notes contained within it, or assign them to a different notebook.

      Clicking on the notebook toolbar button brings up this dialog. To create a new notebook, double click on <New notebook> and type in a name.

      Attachments

      The notes database also stores attachments. This means that the entirety your notes can be contained in your database. Clicking on the attachment toolbar button brings up this dialog. The toolbar allows you to upload an attachment or delete it respectively. Pressing Insert Selected will insert the image at your cursor in the editor (![](image.png)).

      Theme

      The screenshots show the app with my desktop Gtk theme, Arc Dark. On your desktop, it'll use whatever your theme is. It should look good with any Gtk theme, but at some point I may bundle Arc Dark with it.

      The note preview currently has it's colours hard coded to look good with Arc Dark, so it may look a bit off on other themes. I'll try to sort that out at some point.

      Planned features
      • load/save database to/from different path
      • Windows support
      • note exports
      • database encryption
      • changing syntax highlighting theme
      • note tags
      • full-text search
      • proper documentation
      • more keyboard shortcuts
      • integrated sync
        • although you should already be able to use Git, Synthing, Dropbox, etc.
      • Vim mode for editor
        • maybe somehow embed a terminal to allow using vim/emacs/whatever
      Boring technical stuff

      The app was made with Python and Gtk+ 3. I've done this before and I really enjoy the development experience, especially with Glade to design the interface. There are still some Gtk features that I should really be using to make things simpler (GtkApplication, actions, and accelerators) that I'll be adding later.

      The database uses sqlite 3. This is convenient, as it allows for storing everything in one file, and will make fast searches easier in the future. Attachments are stored as base64 directly in the database. This makes it easy to have all your notes be contained entirely in the one database, but I may have to think about a more efficient method in the future.

      Markdown rendering is done using mistletoe, which has been great to use. Syntax highlighting and MathJax renderers were already available, so it was just a matter of combining both and adding custom image loading from the database, which was very easy. Mistletoe has a very easy to use API, so this was no problem.

      For LaTeX math rendering, I'm using MathJax. It supports pretty much everything, which is nice, but it can take a while to load. I'm currently loading it from a CDN in a <script> tag, so I'm hoping once I load it from a local file it'll be a bit faster. If not, I may have to find another solution.

      Like I said, the app still has a few bugs that need to be fixed. If you find any problems, it would be great if you could leave a comment here or open a Github issue (or if you have any feature requests).

      I started using wine in about 2013 and I remember back then it was quite patchy and only worked on some programs/games. I used to have a rule that I stuck hard to that I would not buy any games that did not have a linux version. But now in 2019 I have found that everything I have tried to run in wine has been so seamless and close to flawless that I hardly know its running in wine. I semi regularly buy games that only have windows version because I am mostly sure it will work and can get a refund if it doesn't.

      What does everyone else think about this?

      I'm having some problems with a notebook I want to set up for a friend. And its the first time in a long time I'm not able to solve it just by myself. So I tried asking at #manjaro and #archlinux-newbies but I got no answer at all. It just seems that IRC changed a lot in the last 15 years. Or maybe my IRC manners are not up to date?
      Anyway, do you know a place where there is a nice Linux-crowd? What are your favourite Places to get help? (besides the archwiki) ;-) I'm out of the loop for 10-15 years now because most places got pretty toxic.

      So we have many communities and everyone gets free *nix shell access, you can ssh into the remote server (mostly ubuntu) and do whatever you want! I mostly go there to talk with other users.

      It is all old school, we use the command line and there is no gui that you can work with. You have to use the cli for everything you do (easy to learn).

      You can -

      • learn programming
      • make webpages
      • make new friends
      • play games
      • learn more about *nix

      and much more.

      See https://tildeverse.org to get started. (https://tilde.team/wiki/?page=other-tildes for more tilde servers)

      I'll suggest you to join ctrl-c.club or tilde.town and then try other servers. You can make account everywhere ofc. I am ~cyaniventer on tildeverse, see ctrl-c.club/~cyaniventer
