I ported my free Windows app to Linux, looking for feedback

I have a little GUI tool that adjusts pixel brightness based on screen contents. I made it to reduce eye strain when tabbing back and forth between dark IDEs and Firefox at night. (It also has basic temperature control, which I had to do because unfortunately it conflicts with Redshift).

It was originally for Windows, but I've gotten fed up with that, so here we are.

I'm fairly new to Linux in general, so I'm looking for feedback on whether there's any major issues. (Actually, it'd be great to know if you can get it to work at all). Source code and instructions are here: [https://github.com/Fushko/gammy](https://github.com/Fushko/gammy). Thanks in advance!

P.S. Apologize if this isn't the right place to post this. No idea where else to put it.

What has been your biggest screwup and what have you done to prevent it in the future?

I am sure we all have had a bad day at least once when using Linux. I use Linux for around 20 years now. My biggest screwup was that I was installing a new machine and at the same time I placed the backup hardware in the old machine. I mixed up the machines and deleted not only the data on the main machine, but also on the backup machine.

I needed to reburn 200+CDs and 250+ DVDs. I lost also all of my other data, like emails going back for 15 or so years.

I did learn that having lost the emails is not an issue. The data you absolutely need can be gotten from elsewhere. I now just keep an absolute minumum in data.

For the backups, I now have not only backups but also backups of the backups. For the movies, and music, those are copies. The "real" data is incremntal copies. Only done by pull. The backup of the backup is turned off most of the time. Only comes onine when it does the backup. That is for around 5 minures per day.

I have also learned to work on only one machine at a time. Only when that one works for a week will I go to the next machine. But at that day I felt like a complete idiot. Most likely because I was a complete idiot.

So how did you break things and what did you to solve and/or prevent it?
This might show new users that making mistakes is ok.

PSA: There is no official Pinephone subreddit presence at this time

PinePhone, an open source phone project which can be read about here: https://www.pine64.org/pinephone/, does not currently have a verified subreddit presence. PinePhone is a great and exciting project, however, a subreddit has appeared that is not following reddit guidelines and may try to scam users by appearing to be official. On r/linux, some members of the PINE64 team have project flair and they are the only official reddit presence at this time.

r/linux encourages **everyone** to unsubscribe from all subreddits that appear to be presenting as an official PinePhone presence until further notice. A specific subreddit was linked on r/linux a few days ago and that helped the subreddit grow by over 400 people. That subreddit is ran by someone that has refused to hand over the subreddit to the PinePhone team as well as engages in spam and vote manipulation here on r/linux and has been reported to the admins. Automod rules are in place and the subreddit will not be allowed to be mentioned on r/linux.

**Do not** harass/brigade PinePhone related subreddit users or mods - please just unsubscribe. If you stay subscribed, be aware of scams and unofficial links to buy the PinePhone and report suspicious activity to https://reddit.com/report

To be clear, PinePhone is a legitimate project and this is just about subreddits related to it. You're welcome and encouraged to post directly to official PinePhone resources on r/linux, but no subreddit related to PinePhone is should be followed or linked to on r/linux. We will edit this post if an official subreddit appears on reddit.

While it's ok to have unofficial subreddits (as most are, including r/linux) but per reddit [guidelines](https://www.redditinc.com/policies/moderator-guidelines) it must be clear they're unofficial - and when the mods are engaging in suspicious behavior it became clear that this PSA was needed.

NVIDIA graphics cards on a linux system

Hey everyone first time post here.

I've been using a windows - ubuntu dual boot for about a year since I needed a linux system for a course at university and I have really started to like everything about it (and even started hating windows for it). I've also started playing around with blender which is the main reason that I'm looking into building a new computer since my 3 year+ old laptop is having a rough time. I will be using a Linux distro as the only OS on this machine.

I've just watched the most recent video from Chris Titus Tech ( [https://www.youtube.com/watch?v=QJrh2XqpieE](https://www.youtube.com/watch?v=QJrh2XqpieE) ) where he states that, if you're planning on using Linux full time, you're better of using an AMD Graphics card because driver issues with NVIDIA. I really don't know a lot about this so that's why I'm asking you guys.

What are the main problems with NVIDIA graphics cards on Linux systems? Are most problems a one time occurence with an easy fix, or should I be worried? I planned on buying a 1660ti but, if AMD is the better way to go, I could stretch my budget for the 5700.

Thanks for reading and helping me out!

Can software under GPLv3 be sold?

I've been discusing this for an hour with an IT friend, he says it's not allowed to sell software under GPLv3 without any modification. I said him many times it's allowed and showed him what gnu says about.
What can you say about this guys. Many thanks :)

Hardcore Windows user here, Installed Debian 10 on my actual computer for the first time and currently trying it out.

Going to keep this short

I have messed around with Linux distros on VM, but let's forget about that. Using Linux via Virtual Machine sucks if you don't have a fast computer that handles Virtualization. Personally I recommend Dual-booting instead.

I went with Debian 10 simply because it was the only one that can fit on a 1GB Flash drive while most distros are bigger than 2GB.

So far, my experience has been quite good (despite been using it for 2 days) I have encountered some bugs (which are easily forgiven) and some problems (in which i'm still in progress of fixing at the moment, quite educational).

I'm not going to state these problems or bugs (as I don't want to ruin the surprise) I'll be doing a detailed post regarding my experience with Desktop Linux as a Hardcore Windows user on somewhere between December or January. stay tuned for that.
