Laptop

For a while I've been using Calibre 8.5.0+ds-1+deb13u1 in Debian/Trixie running KDE for reading ebooks on my laptop, it generally works well and has a large font size. The only downsides of it for that use are taking more RAM than I would prefer (about 780M RSS which seems a lot for a relatively simple task) and having separate windows for the list of books and reading an actual book without any options to just open the last book and not delay me.

I tried Arianna 25.04.0-1 in Debian/Trixie, it has a significantly smaller font size and doesn't allow high contrast colors as the default is black on gray with the dark theme in KDE. It also only allows left and right arrows for moving through the book while Calibre uses up/down, left/right, or pgup/pgdn so whatever keys seem reasonable to you are going to work. The RSS was 762M which wasn't great but wasn't the real problem. Rumours of Arianna using less RAM than Calibre seem exaggerated.

Librem5

On my Librem5 phone with Plasma Mobile Calibre 8.5.0+ds-1+deb13u1 both the initial setup screen and the main screen for selecting a book to read don't work in the width of portrait view on the phone. After putting it in landscape mode it worked, but I couldn't touch on a book title to select it I had to touch on the number of the book at the left of the list box. But once it was loaded everything was fine. On the Librem5 Arianna 25.04.0-1 just worked fine, although only using left/right swipes to change pages instead of up/down was annoying.

Furilabs FLX1s

On my Furilabs FLX1s with phosh Arianna 25.04.0-1 and Calibre 8.16.2+ds+~0.10.5-3 both gave the same result of not displaying text or images from the book, I'm not sure if it's phosh or some other aspect of the FLX1s configuration at fault.

PinePhonePro

On my PinePhonePro running Debian/Testing with Plasma Mobile Arianna 25.12.3-1 worked without any issue and up/down swipes worked. Calibre 9.5.0+ds+~0.10.5-1 had the initial screen work fine in portrait mode but the main screen was too wide and needed landscape. Also the issue of having to touch the number applied.

Laptop running Debian/Unstable

Calibre 9.6.0+ds+~0.10.5-2 and Arianna 25.12.3-1 worked quite nicely on a Thinkpad running Debian/Unstable. One thing I discovered while testing it is that Calibre supports the CTRL-PLUS and CTRL-MINUS key combinations to change font sizes and that also works on the version in Debian/Trixie. Arianna doesn't support CTRL-PLUS/MINUS.

Conclusion

The problems I had were Arianna on a laptop, everything on the Furilabs FLX1s, and Calibre's UI not being well adjusted for mobile devices.

Review: The Sovereign, by C.L. Clark

Series:	Magic of the Lost #3
Publisher:	Orbit
Copyright:	September 2025
ISBN:	0-316-54286-5
Format:	Kindle
Pages:	575

The Sovereign is the third and concluding book of C.L. Clark's Magic of the Lost high fantasy trilogy. I recommend reading the books of this series close together, since there are a lot of characters and a lot of continuity between books that is helpful to remember, but it was not quite as difficult this time to remember where the story left off.

At the end of The Faithless, the political situation in Balladaire (not-France) was more stable, but the threat of a plague lay on the horizon. That threat arrives in earnest in this book, along with new threats from both Balladaire's former colonial conscript soldiers and from neighboring Taargen (not-Germany, sort of, although the parallel isn't as close). Luca and Touraine have finally admitted that they're deeply in love, but they are still very different people with different goals and ethics. Luca is determined to do anything necessary to save her kingdom, but her definition of her kingdom is sharp and brittle. Touraine is torn between far too many loyalties, plus the lingering worry that her morals and Luca's may not be compatible.

I think the hardest part of this sort of series is finding an ending the reader will find satisfying. This one, unfortunately, did not work for me, but that may be more due to personal preference than objective flaws.

There have been two threads through this series: an improbable romance embedded in a network of complex personal relationships, and a political commentary on colonialism and post-colonial wars. I was enjoying the former, but it was the latter that felt fresh and interesting to me. The plot threads in The Faithless outside of Balladaire expanded that complexity, and I was hoping the final volume would continue in that direction. How could a colonial power atone for its history? How does the former colony establish its own governance? Is there a path to freedom without violence? Are attempts to chart a more moral course doomed to open lines of attack for one's other enemies?

It's clear that Clark was thinking about similar themes, but The Sovereign narrows the field instead of widens it, restricts the political options, and then resolves most questions in a massive war. This is not that surprising of a conclusion, but it's one that I found unsatisfying and, honestly, a little boring. Yes, one way to resolve all the competing tensions is for everyone to try to kill each other and whoever survives wins, and historically that's one of the more likely outcomes, but that ending doesn't wrestle with the politics as much as it collapses them.

Clark instead focuses this concluding volume on the romance, which becomes even more fraught, tragic, and dramatic than it was in previous books (and that's saying something). The hard questions of divided loyalties and moral conflicts are mostly framed by questions about Touraine's loyalty to Luca and Luca's trust of Touraine. This is all very Shakespearean, full of hard choices, sudden reversals, miscommunication, and a very deep conflict between Luca's realpolitik and Touraine's stubborn personal morality. If this is what you were reading the series for, if you were hoping for a maximum-drama sapphic relationship, you may thoroughly enjoy this. I thought it had its moments, but I wish they had been balanced by more moments of cool-headed practicality and creative political ingenuity.

My biggest frustration with this ending is that the characters largely stop doing politics. The political complexity was the strength of both The Unbroken and The Faithless: People who intensely dislike each other negotiate because there is something larger to be gained, personal decisions made without considering the political ramifications have costs, and multiple characters are trying hard to find a way to turn a nasty, exploitative world into something better without simply killing everyone who disagrees. Many of the characters were objectively bad at politics, inexperienced and immature, but they stumbled or dragged or fought their way into political solutions anyway. I thought Clark moved too far away from that in The Sovereign. Everyone goes deep into their own emotions and desire for vengeance or conquest or revolution and stops compromising. To a depressingly large extent, the story is resolved by killing everyone who disagrees. I think the story is poorer for it.

One of the other threads of the series is Balladairan magic, or rather its odd absence. Luca has one understanding of it, the rebels introduced in The Faithless have a different understanding of it, and its pursuit is set up as critical to resolving the threat of a plague. We do get an explanation of sorts, but it's not as complete or as satisfying as I was hoping, and the symbolism of Balladaire's missing magic is left frustratingly murky. For me, this has some of the same problems as the political conclusion: I wanted an intellectual catharsis alongside the emotional catharsis, but that was not the direction Clark was taking the story.

I like reading about these characters. All of Luca, Touraine, and Pruett are complex, comprehensible, flawed, and often intriguing. But my favorite character in the story, the person I latched on to as an emotional path through the story, was Sabine. Her refreshingly straightforward loyalty and lack of drama was a breath of fresh air. She has some great moments in this book, but there too I got wrong-footed by the direction Clark went with her arc and found its conclusion deeply unsatisfying.

I'm not sure how many of these complaints are because of missed opportunities in the novel, how many were due to a mismatch of taste, and how many were due to not being in the right mood to read this conclusion. I'm sure that it didn't help that I read this simultaneous with another novel in which the characters were always miserable, or that I read it in early 2026 with, uh, all that entails. I suspect that if you came away from the first two books invested in the messy romance and wanting MOAR DRAMA, you may get exactly what you were hoping for. That, sadly, was not what I was hoping for.

I can't really recommend this. I thought it dragged in places and didn't deliver the ending I wanted. But it has some great moments, it does wrap up the threads of the trilogy as advertised, and at least the romance gets a dramatic climax worthy of the tension that has been built through the previous books. If that matches what you were enjoying in the previous books, you may well enjoy this more than I did.

tl;dr

This is not an official package, it's good enough for me and it might be good enough for you, confirmed as working in Debian Testing but I don't have a Stable machine to test there.

You can use my custom repo to install the latest NVIDIA drivers on Debian Stable, Testing or Unstable (install from Sid repository):

https://deb.debusine.debian.net/debian/r-samueloph-nvidia-ai/

The page above contains the APT sources you need, just add the one for your release to /etc/apt/sources.list.d/r-samueloph-nvidia-ai.sources, run sudo apt update and install the packages, you might need to disable Secure Boot.

This is not about AI

Discussions about AI are quite divisive in the Free Software communities, and there's so much to be said about it that I'm not willing to go into in this blog post. This is rather just me telling people that if they need up-to-date NVIDIA packages for Debian, they could check if my custom repository gets the job done.

The AI part is a means to an end, I've been careful to note in the repository names that the packages were produced with AI to respect people who do not want to run it for any reason.

RTX 5000 series support

Back in May 2025 I opened a bug report asking for the NVIDIA drivers on Debian to be updated to support the RTX 5000 series. The Nouveau drivers might be good enough for some people, but I need the NVIDIA drivers because I want to play games and do experiments with open weight models.

Opening a bug report doesn't guarantee anything, at the end of the day Debian Developers are volunteers, so if I really wanted the newer drivers, I would have to do something about it, ideally submitting a merge request.

I briefly looked into the NVIDIA packaging, which involves 3 source packages (and one extra git repo for tarballs), unfortunately this was going to take more time and effort than what I was willing to spend.

What I Did

After a few weeks of lamenting that I wasn't running the NVIDIA drivers, I figured I was willing to put in more effort than I originally thought, just enough to instruct the Claude Code agent to package the latest releases. I'm skilled enough with agentic tools that I knew how to use it to save time; providing a clear instruction on how to build the package and explaining the packaging layout, then letting the agent iterate until it gets a working build. The agent was running inside a VM that didn't have any of my credentials.

After a little bit of back and forth, where I was reviewing the changes guiding the agent into how to fix certain issues, I ended up with a working set of packages.

Once I installed it on my machine and confirmed they worked, I set up a debusine repository to make it easier to install future updates, and let others test it out.

Debusine is analogous to Ubuntu's famous PPA, or Fedora's EPEL, it's a relatively new project but it has been working fine for this.

Matheus Polkorny helped me test the packages and did spot a few issues which are fixed now. The Debusine developers were also always quick to respond to my questions and bug reports.

How Good Is It?

Short answer: good enough for daily use, but not a substitute for an official Debian package.

The whole point of doing this is because I don't have enough free time to maintain the package myself. All of this work was done as a volunteer, on my personal time.

This means I'm trusting the agent to some degree; I review its commits but I don't go too deep into it, the quality will be dictated by the fact that I'm a Debian Developer and so by how easily I can spot issues without double checking everything.

I only have a single machine with an NVIDIA GPU, this machine runs Debian Testing and so I don't have a way to test the Stable packages. I can do my best to address problems but at this point there is a risk that new updates break something.

Installing NVIDIA drivers has always been a bit risky regardless, if you're comfortable with reverting updates and handling a system without a graphical interface (in case you end up in a tty), you will be fine.

You will likely need to disable Secure Boot in order to use them, or set up your BIOS so that a MOK can be used to sign the DKMS modules.

When choosing the version strings for the packages, I was careful enough to pick something that would sort lower than an official Debian package, meaning that whenever that same version is packaged in Debian, your system will see it as an upgrade.

If you have any other methods of installing the NVIDIA drivers on your Debian system that is working for you, you should likely stick to that.

I have a strong preference for installing them through .deb packages, making the package sort out configuration changes and dependency updates, besides handling the DKMS modules.

Ultimately I'm not happy with the amount of difficulty that Debian users have in installing up-to-date NVIDIA drivers, and I hope this makes it easier for some.

How To Install

Head over to the Debusine page that contains both repos for Trixie (Debian Stable) and Sid (for Debian Testing and Unstable):

https://deb.debusine.debian.net/debian/r-samueloph-nvidia-ai/

If you are running Debian Testing, then pick the Sid repository.

That page contains the contents of the apt .sources file you need, create the file /etc/apt/sources.list.d/r-samueloph-nvidia-ai.sources with the sources for your release.

Run sudo apt update and install the packages you need, if you already have a previous version installed, sudo apt upgrade --update would update them.

If there are no upgrades, meaning you don't have a previous version installed, then you need to explicitly install them.

sudo apt install nvidia-open-kernel-dkms nvidia-driver

If you run into issues in Debian Stable, consider using the Linux kernel package from the backports repository, if you need an up-to-date NVIDIA driver, you likely should also be running the backports kernel package (if you can't upgrade to Debian Testing).

Future Plans

I currently have no means of measuring how many people are using the debusine repositories, so if you do end up using it feel free to let me know somehow.

I don't know for how long I will keep managing this repository, and how much effort I will spend, but my machine needs it and for now I will keep it up-to-date with the latest production-grade NVIDIA drivers.

Sources

The sources of the packages are available under a namespace in Salsa (Debian's GitLab instance):

https://salsa.debian.org/samueloph-forks-team/nvidia-drivers-forks-with-ai

You can also get the exact sources used in the repositories from debusine:
