🇺🇦 kraxel’s news is a personal blog at kraxel.org about systems and programming. Since 2015, 10 different Hacker News readers have linked it 15 times, most often “VGA and other display devices in QEMU”. It is still writing: the last post was on 2026-08-06, and you can follow it by feed.
Too few sampled comments (6) to say how often HN recommends it.?
Why HN links it
HN readers link kraxel's blog for Linux graphics and tooling posts, including the fbida framebuffer image viewer, the virgl OpenGL virtualization tag, and a Fedora on Raspberry Pi guide.
Summarised by Claude from a sample of 6 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
Articles about qemu development, firmware work and my linux projects. Also posts about other random things now and then.

To get the performance benefits the VM can't be run with a spice / vnc interface, so there is no virtual screen or virtual input. You have to pass the VM its GPU and some USB ports and can only see/interact through those and the network bridge. My keyboard and mouse can pair to multiple different machines at the same time and switch with a button press so I just do that. Synergy also works fine, you just need to tem…

HN discussion btw. Rendering images or movies on the TTY is common. fbida: https://www.kraxel.org/blog/linux/fbida/ mpv: https://mpv.io/ Fbida sometimes need the -d option pointing to /dev/drm/something, when using screen or tmux. MPV required for years -vo=drm on the TTY but since some months it always works. Nice improvement :) A display server is not needed.

Neato! Many years back I was playing with Xpra for this, but it was in the days before either Docker or useful seccomp. Glad to see something making progress here. Have you looked at OpenGL virtualization e.g. Virgil ( https://virgil3d.github.io/ , https://www.kraxel.org/blog/tag/virgl/ ) for that problem? The idea is to use Gallium to give them just enough access to get host 3D acceleration, but not direct access t…

HN discussionyou don't even need to run the gui and do all the greaskmonkey stuff, its overkill. just set up fbida ( https://www.kraxel.org/cgit/fbida/ ) its available packaged in most distros and you can set up the slideshow right through the command line using the framebuffer to show the images. I've built several picture frames this way.

Seems like sixel would be an excellent solution, thanks very much for that pointer. However, I can always convert PDFs to images and go forward from there, I guess. It's not a bad workaround. The fbi image viewer is available for NetBSD's X Window system; not sure about the framebuffer port. https://www.kraxel.org/blog/linux/fbida/ EDIT: Apparently, NetBSD has lsix: https://ftp.netbsd.org/pub/pkgsrc/current/pkgsrc/g…
