So basically I have a monitor and a TV and I want to have mirrored displays to both. I have had no issue doing this with Ubuntu 24.04 and previous versions however I have just installed 26.04 onto a new SSD. I find that when I boot up 26.04 I have TV monitor on by default and I have to turn the TV on, log into the desktop environment and then both monitors can be used. However, I would like for the dual display option to be a thing prior to log in so I don't have to turn the TV on. In practice, you can just press the Enter key and type in the password, however I don't want to risk anything going wrong and typing in things without knowing what is happening.

This was not a problem on 24.04. Some years ago I learned that display settings can differ prior to the login and I think I changed a file with display options so that the login screen you get was dual for both screens. If this is the case still can anyone remind me on how to get the file in question?

I have (580.173.02-0ubuntu0.26.04.1) Nvidia drivers installed on 26.04.

I wanted to know if I could install Ubuntu on some of the second hand laptops I was considering buying about ​​3 days back and it showed this error(granted I might have open three or four pages at once that day). Today I managed to open the site but after loading 3 pages, it again spit out this error, what to do?

Hey guys. I’m just a few months away from having to replace my laptop, and I want to find one that’s as compatible as possible with DaVinci Resolve. I’m currently using a 13" 2019 Razer Blade Stealth (HP ProBook 450 G6 motherboard, 8th Gen Intel Core i7 quad-core processor, 16.0 GB RAM, and Nvidia GeForce 150MX discrete GPU), and no matter which distro I use, running DaVinci Resolve has always been a headache—I’m not talking about missing codecs or editing without proxies… I’m referring to the overall system stability.

Unfortunately, Kdenlive hasn’t been very stable either; Shotcut makes better use of the dGPU, but neither of them has several features I need. I’ve also tried Drift, but it’s still too immature for professional use.

So, even though I’d be inclined to just go ahead and buy a Framework Pro or consult directly with Tuxedo, I’d first like to know if anyone has had success using Resolve on their hardware with performance similar to what it delivers on Windows, and what software configuration makes that possible.

TIA

Hello everyone, not sure if this is the right area of Reddit so let me know if there's a better place. Running Fedora 44 on a 2012 MacBook Air with a bare niri/Wayland setup — no DE. Trying to set a persistent 80% charge limit.

Tried two approaches:

1. mac-smc-bat-guardian (userspace TUI, direct SMC port I/O via a C helper) — installed, configured BATTERY_THRESHOLD=80 in .env, ran it as root (via su). Battery sailed straight past 80% with no error, no charge_control file ever appeared under /sys/class/power_supply/BAT0/

2. applesmc-next (DKMS kernel patch exposing charge_control_end_threshold via sysfs) — built cleanly via DKMS (manually copied sbs.h into the kernel headers). Module loaded butBAT0 itself vanished from /sys/class/power_supply/ afterward until rolling back.

Both projects list broad Intel-Mac support (2006–2020ish), but I'm wondering if this specific 2012 Air generation's SMC/battery interface is just an edge case that isn't well tested against current kernels (was on 7.1.12 at the time of the crash).

Has anyone gotten charge limiting working on this specific hardware generation, or is manual 80/20 unplugging genuinely the only safe option here? Thanks in advance.

Ordered a computer said they will send it expedited they took the full payment and yet have not sent the computer. Should I get a refund? I do not recommend ordering from them they have terrible customer service!

Original Post

Posted a while back about reverse-engineering the EWEADN H2's protocol and building a native Linux app for it, since the official web driver hides the battery percentage and isn't all that trustworthy about showing you what's actually going on with the mouse. I still owed it real button remapping before moving on to libratbag. That's done now, so figured I'd share.

What's new:

• Full button remapping — all 6 buttons, keyboard shortcuts, media keys, the DPI button, double-click
• Battery reading no longer occasionally shows garbage values
• Works properly while charging now (turns out it's a different USB device in that mode)
• Cleaner-looking Device tab in the GUI

Same repo, same place: https://github.com/MuhtasimJawad/EWEADN-H2-Control

If you've got this mouse, I'd still love to hear whether it's working for you — bugs, weird behavior, anything.

Edit: quite a few of you asked about libratbag/Piper support so this could work with the normal Linux tools instead of my own app — that's well underway. DPI, polling rate, and all the button remapping above already work through a proper libratbag driver, tested on real hardware through both ratbagctl and Piper. Will post again once it's ready to send upstream.

as the title says. i'm looking to switch to linux mint in the far future, but i'm not sure if my laptop is compatible. lot's of people say that "linux is for every laptop", but i've heard that acer models can have issues, especially budget models with mediatek as it's primary wifi provider. i've also heard about various driver issues with video and audio, and it makes me worry. i plan to switch to linux when windows 11 eventually kicks the bucket, but I don't wanna be stuck with a laptop that can't run Linux let alone windows 11. This is the only laptop I own, and I wanna make sure that in the future i'm making the right choice and fully prepared for what could happen.

I am trying to buy a MangoPi MQ-Quad board and test it out. Everywhere I look it seems out of stock or super expensive. Dhgate has it for over $234 for example. Anyone know where to buy this board? I saw the schematic and other files were released so I considered remaking it in Kicad but that would be a lot of work

I'm building a router on a Lenovo m720q. The router really doesn't need much space to be happy; and a 16Gb optane module from the Bay is a lot cheaper than any NVME SSD I can get new, and the 256Gb SSD I have in it now could serve better elsewhere that needs more storage.

Can I use an Intel Optane module as a boot device? They're running about $12 on fleabay right now for a new one...

Will be looking at a second hand Ideapad 3 15IIL05 i3 4GB soldered model. Wondering if everything will work for Ubuntu?

Found this old system running, currently has Void Linux installed on it. Specs:

• CPU: Intel Pentium Dual-Core E2160 @ 1.8GHz
• Motherboard: Intel 945GC (PI945GCM)
• RAM: 963MB
• GPU: NVIDIA GeForce 7300 LE
• Currently running Void Linux

Not looking for server/homelab suggestions, already have a server for that. Curious what else could be done with something this old and low-spec. Open to ideas.

What's the best laptop right now for installing Linux and maximising it to one charge per day, something like 6 to 8 hours of moderate use with docker, IDEs and that kind of stuff running?

Totally new to this but I did some research and I land upon a few routes as far as I can tell right now. Been looking around and checking out what people has been doing recently and eyeballing second hand devices. I personally have a razorblade 16 with me so I'm not gonna bother playing games on this device, the goal is a highly mobile device that I can take with me on the move for work.

• macbook air or pro, 13" or 14", m1 or m2 or soon m3 as asahi announced, I know any linux on it is going to drain a bit more power on it, but I hate macOS as much as windows thus we know what to try out next. I'm hoping It'll probably be 6 to 8 hours of real use battery. So I need your thoughts and if it is really a big tax on the battery. (I'm leaning on trying out m1 pro 14" cuz they have higher ram options)
• or take the compromise of using older generations of thinkpad, x1 carbon, T14s or T14 which will have less battery hours, I'm thinking potentially 4 to 6 hours could be less... and it definitely differ by generations and cpu chip, more importantly most of my locally sourced second hands are old power hungry intels, 11th to 13th gen cpu.
• or is this simply not viable and macbook with macOS is the only way.

If any of you have those setup or you have a different solution please let me know what your model is and how well it behave.

Hello, I was wondering if Lenovo Yoga Pro 7i Gen 11 supports linux. Specifically how is the nvidia GPU? Does hybrid gpu work (activate dedicated gpu only when needed)? How is battery life?

I'm new to Linux and currently learning to use Ubuntu 26.04. I'm trying to set the smart shift on mx master 3 to a) if the application have tabs, close the current tab (ctrl + W). b) if the application doesnt have tabs, close the application (alt+f4). I've been following AI instructions to do the first part, but havent had any success. here's what I've done 1) change key/button diversion for smartshift to diverted. 2) add it in rule editor, Key Smart Shift (00C4) pressed, Key press Control_L + W. but it didnt work, 3) edit YAML with Key: [Smart Shift, pressed] KeyPress: [Control_L, w]. again, didnt work

Hi!

I'm considering going freelance as a web developer, and need a new laptop.

My last work provided me with an M4 Pro (14", 24Gb Ram) which I really liked, but I can't justify buying a new Mac since I won't benefit from the Apple ecosystem. Plus I'd like to be able to customize it a bit.

So I'm now looking for something similar performance-wise, and of course fully Linux compatible. I don't mind not having the best battery ever. I liked the comfort from the 24Gb the Mac gave me so I'm looking for this at a minimum.

Do you believe a 2k€ price tag is possible? I'm considering refurbished if it's from a trusted seller that can ship to France.

Thank you for any suggestion!

I have a 15.6" HP 255R G10 with a Ryzen 3 7335U, currently running Linux Mint 22.3 on kernel version 7.0. I have a very specific issue with the integrated microphone. In theory, it should work and be detected by the kernel because it recognizes the Realtek ALC236 chip, but after doing some troubleshooting with Gemini AI, we came to the conclusion that the BIOS pin mapping is incorrect. Is there any way to fix this with a driver or patch?

Need a tablet for work. Maybe a little web browsing will be done, but almost 100% for opening/signing PDFs & such, viewing some MP4s & similar. Apparently Fedora is one of the better distros for this, but probably almost anyone on this subreddit knows better than me on that front.

Hello, I'm on Fedora KDE and I wanted to know whether a 100% on the sound (kde) or on pavucontrol apps means that you're using the native input volume of the microphone, or will I have to check alsamixer?
