Wayland GUI in an Unpriviliged LXC container (proxmox)

Hi all, I’ve recently got a proxmox server up and running, and cutting my teeth on it setting up some services (thanks to everyone who responded to my earlier post!). One thing I’m struggling with currently, and it’s admittedly not straightforward, is getting a graphical session up and running.

What I have working so far is an arch based lxc container, with gpu pass through. nvidia-smi on the lxc reports as usual, and so that seems to be working fine.

Upon installing a graphical session, say cinnamon, with lightdm, however, I can’t seem to open any display. I can have a virtual terminal available via the proxmox ui, and though I haven’t tried, I’m sure I could ssh in just fine as well. For what it’s worth, I have a display connected to the host system; the host does not have any graphical sessions. I’d like for the time being to use this host display, and have passed through /dev/fb0.

What I haven’t tried is running a pure x11 based session. I’d really prefer to use a Wayland session with cinnamon, but if necessary I can try to get an x11 session running. I additionally have not installed any vnc servers.

The errors I tend to get when trying to start cinnamon center on not being able to get a session ID, not being able to connect or open a display, and not being able to connect or find a dbus session.

Lightdm says it is running as a service on systemctl status lightdm.

Anyone have any ideas for how to get a session going graphically? I’m not sure how to even pass a tty to the connected monitor from the lxc.

Thanks for any help or guidance — if I do figure this all out, I plan to make a guide for future folks.

Bambu Lab Controversy Deepens: Firmware Update Sparks Backlash
  • Prusa Core One. Can buy it prebuilt or as a kit.

    Disclosure: I do not have one. I have a creality k1 and it’s mostly great for me, but it isn’t perfect and I personally would buy a prusa if I was buying a new printer.

  • Pharmaceutical companies are actually legally required to find out if you’re misusing their product or taking it in an undirected way, and report that to the FDA. Well, has been that way historically, anyhow. If you even work for a pharmaceutical company and you overhear at a weekend barbecue that someone has not taken a dose or doubled a dose etc, you’re obligated to report it within 24 hours.

  • First time software set up help
  • Yeah, I think I’ll go with proxmox as a first attempt — it seems to fit what I’m looking for and the feedback here has been pretty positive on that front. My main concern now is figuring out how to provision the hdds so that a jellyfin lxc can utilize it, nextcloud could use it, and I can save (configuration) backups to it. I’m comfortable with zfs in general (run that on my desktop), but I was under the impression that raid10 would be more performant with the same redundancy, when using 4 disks in raid10. Any one disk could fail, writes are at the speed of the disk because of mirror, and reads are 2x. I lose usable disk space, but I think 16tb is enough for me (for now of course haha). Am I wrong though on the zfs vs raid10? I guess actually I could use zfs, create a single pool with two mirrored vdevs. I am not sure how that would affect future growth, but should do really well for now. Does that sound like a reasonable thing to do, in your opinion?

  • First time software set up help
  • Hey, thanks so much for the response, this is great! Love the idea of offloading ai workloads to their on vms to make facilitating managing resources easier.

    Also, big thanks for the recommended software — very helpful list for me to look through, especially on the AI front. Do you have any notes on configuration for those in particular?

  • First time software set up help
  • Thanks for the reply!

    My understanding was that with only 4 drives, raidz would lower read throughput and not add much space / redundancy. Is that not true? Would you mind giving me a few more details on how you’d set up a 4x8tb raidz array (or could point me to a tool / resource that could help me? I haven’t been able to fully convince myself either way)

    Hi everyone, I am trying to repurpose a Ryzen 1700 system for a home server, but not exactly sure what the best solution for my needs is, and how to find additional resources.

    More context, I have 4 8th hdds (wd blue drives; would’ve preferred reds but, alas). I intended to run these in raid10, but open to other ideas also. These are connected via sata directly to Mobo. I’d like to selfhost a nice NAS stack, to include: my own office 365 / google docs thing, file storage, and storage and playback of music and video files. I’d like to run jellyfin and a myriad of ‘arr things. Please send any and all suggestions. Should all of these run on a single virtual machine?

    Alongside this, probably in a separate virtual machine, I’d like to run a home assistant instance with some mild transcoding (I think) going on in regards to some cameras I have around the house.

    I also think I’d run tail scale to vpn back in?

    What I’ve researched so far is proxmox and casaos (lightly). Casaos is alluring mostly because it seems like an easy on ramp, with lots of visual configuration. I enjoy CLI config, but visual configs are easier to discover settings and options that might not occur to me. I’d ideally favor stability here, as I like to tinker, but don’t have a huge amount of time for it.

    Am I on the right track with all this? Any pitfalls? Any must have self hosted software I should be sure to include? Should I set up the storage pool in proxmox first as raid10? Any general advice? Words of encouragement? I’ll take it all.

    Apologies if this is the wrong forum — if so, please feel free to delete (and direct me hopefully to a more appropriate locale).

    Edit: forgot to mention, system also has a slower ssd boot drive, and a 1070 I plan to pass thru as needed.

    US expands attempt to blow up Google with proposed teardown of its ad technology
  • I think actually they just want all the data Google has for free or cheaper.

    In an ideal world, googles ad network is brought low, and the data is destroyed and people care about their privacy and make it much more difficult for replacement players to harvest their data.

  • The Trump Admin Thinks Affordable Fiber Broadband Is ‘Woke’
  • From the article, there were some requirements to try to avoid that waste:

    “ Like demanding ISPs provide at least one tier of service poor people could afford. Or encouraging networks built with taxpayer money be open access, which, as we’ve discussed at length, helps boost broadband competition and lower costs. As well as encouragement that taxpayer money be spent on the most future-proof technology (fiber) where applicable. Pretty common sense stuff. “

    I presume funding or continued funding was contingent on these sorts of things, which is probably why they (republicans, corporate class ISPs, etc) didn’t like it.

  • Do you see what's going on yet?
  • Yeah, I just can’t seem to find their proposed amendments. Maybe because they weren’t considered or something? I’ll have to see if I can find the cspan section. I just want a snippet to show my family where Republicans are voting lockstep to protect wealthy people.

  • Is Civilization 7 not fun?
  • Did you read the reviews? Most are absolutely thrashing the UI which is critical for a game like this. Probably best to steer clear for now. You could try a previous civ game though, or endless legend maybe?

  • Creality K1 Intermittent Buzzing
    streamable.com Streamable Video

    Watch this video on Streamable.

    Streamable Video

    TLDR: is the buzzing in linked video normal / okay / expected? If not, is there a way to fix it?

    I’ve just been putting my Creality K1 through it’s paces, and after using up all the hyper PLA that came with the unit, started printing some inland black basic PLA. Since then, I’ve noticed some buzzing sounds on either pure x axis or pure y axis moves. Video attached showcasing it. It doesn’t seem to create any buzzing on infill moves or perimeters that have a radius. Any straight lines though seem to cause the buzzing. Prints seem okay (though inout shaper seems off for sure looking at corners). I don’t remember it happening with the hyper PLA which I printed at the same speed (I am printing the black inland at higher temp to compensate for reduced flow).

    Thanks for any help or feedback! Enjoying the community on Lemmy here so far :)

    Creality K1 Tramming -- Loosen Z Screw and Tune?

    My Creality K1 bed is actually in pretty good shape (max deviation of 0.7mm left to right, 0.1mm back to front), but I recognize that many folks might have beds that are off as much as 1.5 or more mm. The K1 has 3 lead screws, but not proper 3 point leveling (maybe someone will create a daughter board and a 3 point conversion kit in the future, after Creality open sources their firmware for the K1 series -- anyone out there that does this, I'd probably throw some small amount of money at you).

    As far as I understand it, there are currently two methods to properly tram your bed:

    1. Follow the creality way, which is essentially immobilize the bed with shipping screws and retension the belt that synchronizes the 3 Z screws. To do this, you must turn the printer on it's side, remove the bottom panel, and fight the tensioner. Reports are mixed luck doing this.

    2. Skip teeth. You still have to do the bottom removal, but instead of completely removing the belt and detensioning, you slip the teeth on the belt drive (I think this is something like 0.4mm for each slipped tooth). There is less information about this, but there's a video in Chinese showing someone doing it. Perhaps a more helpful guide would democratize this more, and it might have more success than 1?

    My question is: there are grub screws on the 3 lead screws, on the top side, accessible from the printer cabinet -- would it be possible to loosen the grub screws, so the z rod in that position spins freely, turn that z rod just slightly, then reseat the grub screw? That would seem a lot easier to relevel the bed, than doing either of the above procedures. Am I missing something?
