    I'm want to start writing device drivers for ubuntu. What should I learn before starting to learn this?

    Posted: 30 Jul 2021 12:55 AM PDT

    My dad asked me to learn how to make device drivers on my ubuntu computer, I have basic knowledge of simple commands, how to use files and directories and I know how to write in c based languages and in c(as a novice). What things should I learn and look into before starting to learn making device drivers?

    Is it normal to have firefox/tor using full GPU power?

    Posted: 30 Jul 2021 10:43 AM PDT

    Compared to chromium, firefox seems to work like a browser would with hardware acceleration turned off. Except it is using the GPU, which hits 80% or more usage when playing a youtube video. Hitting 60ºC just for scrolling through video subreddits

    On windows this doesn't happen, except that it seems that firefox will use more VRAM than Chromium browsers.

    This has happened on any distro I tried: POP, ubuntu, fedora

    Worthy mentioning that I'm using 4K resolution and a GTX 1060

    I thought it was a driver issue, but POP! comes with native support for NVIDIA Drivers

    Is this a normal behavior? I tried searching for a solution, but most questions on stackoverflow are different bugs, not related to 4k lag on firefox.

    And if it is not a normal behavior, should I report/try to get support with this bug from who ? Nvidia? Firefox developers?

    Program to control Monitor Brightness (Desktop) ?

    Posted: 30 Jul 2021 02:04 PM PDT

    Hello penguin army, I've been using Linux (Arch btw) for a few months now and never had any luck finding a software to control / change my monitor brightness (not night color or anything like that). I'm looking for something similar to what ClickMonitorDDC does on Windoze machines for example.

    The Backlight page alternatives on the Arch Wiki don't seem to work very well for me and I know for a fact that many DE's offer this option for laptops (usually in the battery icon or brightness settings) but they simply won't appear or won't work in Desktop setups...what can I do about it?

    OS Update bug

    Installing Linux on External SSD

    Posted: 30 Jul 2021 12:48 PM PDT

    Currently, I am using Asus TUF A15 Gaming Laptop with windows 10 and I don't want to mess up with Windows OS. So, I researched and decided to install Linux in External SSD and I wanted to know that is it convenient?

    1. will Linux run smoothly on an external SSD?
    2. 250GB External SSD will be enough for installing Linux?
    3. After installing Linux on External SSD, will it run smoothly just like the main OS, and will it adapt my laptop's 4GB Graphics card (AMD Radeon(TM) Graphics and NVIDIA GeForce GTX 1650) and RAM (8GB)?
    4. What are the things to keep in mind during installation?
    5. are there any suggestions?

    Will need to know Linux for university, not sure which distro is best

    Posted: 30 Jul 2021 08:34 AM PDT

    Hi all,

    According to the course materials for my university there will be an emphasis on Linux when I go in September, however the university will not say which distro we will be using, or even if it will be rpm or deb based. I know the very basic of deb and I am able to update the system, make directories and change things with nano, but I would like a greater understanding so that I am more prepared, without a specific purpose I find myself clicking around the GUI and just using "man" on everything.

    I have taken the Linux Distro quiz from the FAQ and it has suggested:

    • Debian
    • Devuan
    • Arch

    as the top three however each is not recommended for beginners, but I feel being thrown into the deep end may be a good way to learn. I plan to use Linux in a virtual machine, rather than replace Windows as my main OS but I feel this is somewhat limited as I do not have a reason to use the VM, I can login and move around but I never find a reason or task that requires me to have knowledge of the system.

    Do you guys know of a good distro for a beginner who's purpose is to learn Linux and its commands, preferably with a goal or something to work towards in order to learn?

    Pop_OS fan control

    Posted: 30 Jul 2021 11:47 AM PDT

    Hey guys,

    so I basically just came back to Pop_OS (21.04) after a year or two, since I had used it a bit before and really liked it back then (I'm still mainly a windows user). I installed it on my laptop which I barely use and usually serves as a guinea pig for OS's, since university is remote right now, so I do everything from my desktop. Now the thing is, I remember back then I had a lot of trouble with the thermals and fans of my Laptop (Lenovo T490 - i7 8565u Nvidia MX 250) and I just noticed it got pretty hot again. I had windows installed for a while but as I didn't really use it I have no clue how the fans worked with Windows.

    My question is: Do I have to worry about my laptop overheating or does Linux have safety measures for it and are there easier to use applications now, that help me control my fans so they neither work too hard or make my computer overheat?

    Thanks a lot in advance! :=)

    Unusual auto generated fstab (Fedora)

    Posted: 30 Jul 2021 10:28 AM PDT

    When I did some changes to my fstab today, I noticed that the home and root entries didn't specify the UUID, but /dev/mapper/luks...

    On my other machines and previous installs all entries always where using the UUID (both encrypted). Is that normal or does anyone know what happened here? Used the same installation medium as on the other Computer.

    Difficulty bridging PulseAudio to JACK

    Posted: 30 Jul 2021 08:24 AM PDT

    In Cadence, I can start JACK without any errors but when I attempt to click start in the PulseAudio tab under JACK Bridges, nothing happens and I get the following output from Cadence.

    Cannot open lsp client JackShmReadWritePtr1::~JackShmReadWritePtr1 - Init not done for -1, skipping unlock JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock Error: cannot connect to JACK, jack_client_open() failed, status = 0x21 PulseAudio is already running, bridge it... Failure: Module initialization failed Failure: Module initialization failed Done 

    Not sure if this is related but just in case, I can open Catia through Cadence but the window just stays black, and Cadence outputs this.

    /usr/bin/python3 /usr/share/cadence/src/catia.py & Cannot open catia client JackShmReadWritePtr1::~JackShmReadWritePtr1 - Init not done for -1, skipping unlock JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock JackShmReadWritePtr::~JackShmReadWritePtr - Init not done for -1, skipping unlock

    How to make windows snap when window touches monitor borders in Openbox

    Posted: 30 Jul 2021 08:00 AM PDT

    I like the Windows 10 features that snaps a window when you drag a window to a border, this feature also is in kde and gnome, any way to do this on Openbox? Also I would like to be able to resize with Super + Right mouse button without needing to be on a window border and Super + Left mouse to drag windows

    Im dual booting windows 10 and ubuntu 20.04 and want to switch to ubuntu to PopOS

    Posted: 30 Jul 2021 07:46 AM PDT

    Hello! I dont know what to flair this but installation seems the closest. As the title suggests, I want to switch my ubuntu partition to PopOS. My question is, will it mess up my windows if I reinstall grub? I had many issues with grub and windows last time so I want to make sure nothing breaks. Thanks!
