PLEX MEDIA SERVER is missing… sort of

PLEX MEDIA SERVER is missing… sort of:

Fairly new Ubuntu 18.04 build. Got PLEX installed, migrated from windows 10 box and everything went perfect. The media server is still up and running. I can watch items remotely on client devices. I added files to it and it updated itself. I can even get to it via PLEX.tv but I cannot actually open the application on the host machine. According to Ubuntu Software it is installed, when I click launch nothing happens. When I open applications it is not listed. I still retain a large percentage of it’s functionality but I want access to the app so that I can get to all settings if needed. Anyone seen this before? Thoughts or suggestions?

Switching to a linux laptop for research (Xpost r/linux):

Hello r/linux4noobs!

Originally posted this on r/linux but my post was removed for being offtopic and more appropriate for this sub. Got some great feedback (Thanks if you’ve already seen this!) but can’t get back to people since the thread is locked.

I have just started a PhD in machine learning and the university is kind enough to supply a laptop as my primary workstation. I’ve been a happy mac user for ~5 years but am considering the switch to a linux based OS to get some more mileage out of the budget. And because I want to be able to tinker a bit. However coming from mac the options for machine and OS are a bit bewildering. Can the good people of this subreddit give me some recommendations? And possibly things to watch out for when making the switch. Thanks in advance 🙂

Budget caps at 3000 euro but would prefer to keep it at ~2600

Things to check:

Decent amount of power – A lot of my experiments are going to be run locally so I need a good CPU with at least 16GB of ram. Would like a decent GPU as well but that is not a primary concern as we are not focusing on running deep NN’s

High Res screen – I want to work for a long time without getting a headache. Preferably 15" size

Battery Life and Portability – Usually I’m plugged into a charger but the option of working on the go is necessary. If I’m dead in the water after 3 hours on battery I’ll be an unhappy camper

Storage – 256GB of fast SSD’s at least. Anything else is just gravy

Projectors – I’ll probably use it for conferences, teaching etc as well. Don’t want to wrestle with issues connecting to an external projector and look like a doof in front of my peers.

For OS distributions it’s anything goes, as long as I can get up and running decently quickly. I’ve messed around a bit with Ubuntu on Azure VM’s but that’s as deep as I’ve been so far. Pretty much want to get work done and not have to wrestle the tools (too) much.

Thanks for letting me pick your brains!

TL:DR. Looking for research laptop to transition from mac os. Limited idea of Linux ecosystem. What would you recommend? Budget ~2800euro

Any command to see a human-readable description of a package/program?:

I know about `dpkg -p x` where x is the package name, but that isn’t working for me…(I’m on KDE Neon). I’ve also tried `dpkg -info x` but that didn’t work either.

Any other ways?

Linux Ubuntu OS on Samsung Galaxy TabPro S – Help with Wifi:

I am fairly new to Linux, so I am trying to learn how to do everything. I just did a fresh install of Linux Ubuntu OS and everything works great except for the Wi-Fi and brightness adjust s. I do not have an ethernet adapter, but I do have an additional computer I can use to download the drivers on for the Samsung tablet. I have installed drivers from gethub, and put them in the firmware folder but I am not sure what else to do from here? I tried restarting but no go! Any help would be grateful!

How to get return values (return codes, exit statuses) from a program?:

So, when you create a program in C/C++, main() must return int when the program is finished, and return value of zero means normal exit, and return value of non-zero means error, etc. And I’m using only CLI, no GUI. So, in manual pages of some GNU programs that are default on most distos, there are mentions of different exit/return codes that match different errors. How can I get/pipe those return codes?

Can anyone recommend a USB Wi-Fi adapter that works well with Linux?:

I need a USB Wi-Fi adapter for my Linux box, preferably from a reputable brand, is capable of 802.11ac and is dual band (2.4 GHz and 5 GHz), though I can settle for 802.11n and 2.4 GHz if that is the only option.

I’m using Ubuntu 18.04 but I would prefer something that works with most Linux distros.

Can anyone make a recommendation? Thanks!

Tilling treats dual monitors as a single monitor:

I am having a problem with Cinnamon 18.04 where window tiling is treating my dual monitor setup as a single monitor e.g. when I click super + left or click and drag a window to the left border of my monitor, the selected window takes up the enter left monitor instead of just the left side of the monitor.

In System Settings > Display, it does show that I have two separate monitors. Does anyone know how to correct this?

SSH & SCP (kind of a gripe)

SSH & SCP (kind of a gripe):

Why does SSH use ’-p’ but scp uses ’-P’ to designate a port? Why didn’t SCP stick with ’-p’. This is probably not the right place for this question, but it’s annoying and I can never remember which p to use and always have to reference the man page when designating a port….
