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material out there seems to differ based on distro, DE, and also time, so posts from even a year or two ago can be outdated or inapplicable.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.

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 :

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!

This post is related and in some part a repetition of my other topic on how to buy a laptop for Linux.

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:

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

Edit: Not related to tildes.net

I've been running Linux for a little over a year now and, after a recent conversation on Tildes, I decided that I need to wipe and re-install so that I can enable full-disk encryption.

Thus, right now I'm shopping around for a distro and trying out different live environments to find something that works for me. My question isn't necessarily for right now though (my hardware is old enough that I'm definitely going to need to use a lightweight distro, which severely limits my options). It's more for the future, in that I plan to replace this computer in a year or two with something up-to-date, which means I'll be able to run any distro under the sun! Any!

So, I'm curious to hear from people who have found their "forever distro." What do you run for your everyday use, and why? Also, what's your level of technical expertise? I am very far from a power-user at present, but I'd like to be somewhere closer to that when I replace my computer.

Over the past year I have done a lot to shore up my digital privacy and security. One of the last tasks I have to tackle is locking down the many personal files I have on my computer that have potentially compromising information in them (e.g. bank statements). Right now they are simply sitting on my hard drive, unencrypted. Theft of my device or a breach in access through the network would allow a frightening level of access to many of my records.

As such, what are my options for keeping certain files behind an encryption "shield"? Also, what are the potential tradeoffs for doing so? In researching the topic online I've read plenty of horror stories about people losing archives or whole drives due to encryption-related errors/mistakes. How can I protect against this scenario? Losing the files would be almost as bad as having them compromised!

I'm running Linux, but I'm far from tech-savvy, so I would either need a solution to be straightforward or I'd have to learn a lot to make sense of a more complicated solution. I'm willing to learn mainly because it's not an option for me to continue with my current, insecure setup. I do use a cloud-based password manager that allows for uploading of files, and I trust it enough with my passwords that I would trust it with my files, though I would like to avoid that situation if possible.

With all this in mind, what's a good solution for me to protect my personal files?
