  • Thank you! Once I can figure out the margins I’m going to get a custom btop preset configured. Right now I can’t configure it in a way that important info isn’t cut off on the edges.

    The TV does have dials to adjust, but only slightly, and if I adjust too much, it messes up the scan lines and the signal doesn’t come through clearly. I feel like the answer is just a little further down the rabbit hole of kernel params :)



  • This was really helpful - It got me pointed down the right track to figure out the video= settings in the grub config. I was able to disable the laptop monitor and enable the CRT by adding this to /etc/default/grub

    # Disable laptop monitor (LVDS-1) and only output to CRT (HDMI-A-1)
    GRUB_CMDLINE_LINUX_DEFAULT="video=LVDS-1:d video=HDMI-A-1:1024x768"
    

    I initially set it to 640x480, but display was better with higher res and large font size, which I scales up with sudo dpkg-reconfigure console-setup

    I created a service account for this, and set up a systemd service to start getty on that account based on those docs

    [Service]
    Type=idle
    ExecStart=
    ExecStart=-/sbin/agetty --skip-login --noreset --noclear --autologin axies - ${TERM}![](https://ttrpg.network/pictrs/image/cf0ab3f3-9674-4578-a230-c8f3df7a7bdc.webp)
    

    Then I added htop to the ~/.bash_profile for that user and… done!

    Only thing is there is some overscan on the display and initially about 3 rows / cols were cut off on each side. I was able to adjust the CRT display itself to mostly mitigate this, so now only a bit is cut off and it’s usable, but it’s not perfect. I tried setting the margin in the video options in grub with margin_top, margin_left etc., as per these docs but that didn’t work, even though I verified the resolution was applying correctly. But it is functional!





  • I do get a tty and that works fine if I start it manually. I can also ssh into it while on my local network.

    I think what I need to configure is to have it automatically start a tty at boot with specific credentials and auto start whatever monitoring I want. That should work I think. The only downside of that is I don’t want it to run on the laptop screen at all, only the hdmi output, so that is where I want to learn more about how all of those display interfaces work on linux so I can configure the service accordingly (I think)



  • From what I know, headless means different things depending on context - in this instance I’m using it in the sense that my server does not require any user session, or any user input devices, it just powers on and all of the services start up at the system level. I can SSH into it to configure things, but it doesn’t require any user session or input to run the services. A video output probably falls outside of this in some sense, but I would like it to be automatic without requiring an active user session.

    The monitor I have is an old Panasonic tv / radio combo, so the display can be flipped on with a physical switch when I’m at my desk, so shouldn’t be any wasted power usage. It won’t be on all the time.

    I’m using Linux Mint, which is probably not optimal, but I had a USB ready and I’m just using terminal stuff so it didn’t seem like it mattered too much. It does have systemd, which made it pretty easy to set up the docker stuff

    Thanks for the input!






  • I’ve seen some people say they got fusion 360 working on linux with bottles, but I didn’t have any luck with it. I use OpenSCAD and FreeCAD for making models to print, but if you need Fusion360 specifically for work (or specific Adobe products) then you are kind of stuck unless your company is ok with a change. You won’t be able to view or edit other people’s Fusion360 files without that specific application. You can always run Windows in a VM on linux and install only the applications you need it for there. If you have a good enough PC that is viable, but isn’t a great experience on a lower end system.



  • I installed Bazzite and it felt so much like installing Windows for me (huge install image, slow process, lots of loading wheels and user friendly “pretty” screens to get set up). It didn’t feel great, but I figured I’d give it a fair chance and learn how to use a different setup than I’m used to.

    I still haven’t had a chance to actually do much with it (only a couple of hours between work and other stuff) but I am really interested in the concept. After reading up more and watching some videos I now understand why the install process is so big and the reasoning behind it. This type of distro really does seem like a great option for regular users.

    Only issue I’ve had so far is connecting to my RaspberryPi to control my 3d printer using the .local hostname, since flatpak apparently has a bug with mDNS. IP works fine, and I did rps-ostree install a browser, which was kind of a pain, and probably not the correct way to address the issue, but that was within the first hour or so of using it and I haven’t figured out the best way to do that type of thing yet. Really looking forward to learning more about the setup and how to customize stuff on top of it. Distrobox seems extremely powerful and sounds like it will give me everything I want.

    Still have vanilla Debian on my laptop, which I absolutely love, but using it on my desktop PC was kind of a pain due to some proprietary drivers required there (nvidia).
