WebReady is a simple tool for converting videos to animated webp images and thus allowing users to use them as animated wallpapers for KDE. The tool is primarily designed for steam deck, but works perfectly on any KDE powered desktop.

I'm having trouble allocating more VRAM to my QEMU virtual machine. Currently, I'm using the following command to launch my VM:

qemu-system-x86_64 -enable-kvm -boot menu=on -drive file=QEMU -m 2G -cpu host -vga virtio

Can anyone help me figure out how to increase the VRAM allocation in QEMU?

Hour after I come to this, I'm loving it. She modified it so it retains original kde look but has enough tiny details to keep it interesting. She says she'll resume the work tomorrow 🫡

What was your last RTFM adventure? Tinker this, read that, make something smoother! Or explodier.

As for me, I wanted to see how many videos I could run at once. (Answer: 60 frames per second or 60 frames per second?)

With my sights on GPUizing some ethically sourced motion pictures, I RTFW, graphed, and slapped on environment variables and flags like Lego bricks. I got the Intel VAAPI thingamabob to jaunt by (and found that it butterized my mpv videos)

$ pacman -S blahblahblahblahblahtfm
$ mpv --show-profile=fast
Profile fast: 
 scale=bilinear
 dscale=bilinear
 dither=no
 correct-downscaling=no
 linear-downscaling=no
 sigmoid-upscaling=no
 hdr-compute-peak=no
 allow-delayed-peak-detect=yes
$ mpv --hwdec=auto --profile=fast graphwar-god-4KEDIT.mp4
# fucking silk

But there was no pleasure without pain: Mr. Maxwell F. N. 940MX (the N stands for Nvidia) played hooky. So I employed the longest envvars ever

$ NVD_LOG=1 VDPAU_TRACE=2 VDPAU_NVIDIA_DEBUG=3 NVD_BACKEND=direct NVD_GPU=nvidia LIBVA_DRIVER_NAME=nvidia VDPAU_DRIVER=nvidia prime-run vdpauinfo
GPU at BusId 0x1 doesn't have a supported video decoder
Error creating VDPAU device: 1
# stfu

to try translating Nvidia VDPAU to VAAPI -- of course, here I realized I rtfmed backwards and should've tried to use just VDPAU instead. So I did.

Juice was still not acquired.

Finally, after a voracious DuckDuckGoing (quacking?), I was then blessed with the freeing knowledge that even though post-Kepler is supposed to support H264, Nvidia is full of lies...

SO. What was your last RTFM adventure?

I am a certified Linux user with almost 10 years of experience.

Please run the following command in a terminal:

sudo apt update && sudo apt upgrade -y

Let me know if this fixes your issue

I'm going to be building a new computer soon for myself. (Going AMD for the first time, since intel microcode issue.)

I would say I'm an expert or advanced user, as been using pcs for 25 years and set up arch and slackware in the past. I have tried many distros and would like some feedback.

I mainly use my pc for gaming. I want something customizable, KDE ish, and without bloatware. A good wiki is a plus.

I think that i may end up with arch... is it better for gaming since it's bleeding edge and isn't steamos built off it?

Side question is distro chooser accurate?

recently I've started working with an open source java gui app that uses jpackage to generate system packages for distributions.

I'm interested in creating a flatpak for this, but I'm not sure what best practices look like for this. Should I attempt to take the files that are generated by jpackage and put those into a flatpak, or should I just take the jar file alone as provide that with a dependency on a runtime that provides java?

fair warning I am a noob in regards to flatpak

I'm currently using Fedora KDE Plasma, but I'd like to try out a tiling window manager. What would you all reccomend? I use my computer for school, so I would like it to be stable.

Hello, i have task to install a system for elderly person without much technical knowlegde (never used pc, no windows or mac).

They need text processing, calculator and maybe spreadsheet.

Want to disable anything else (setting panel, file browser, web browser, launcher, dock, terminal, login select, etc.) that not needed, all important thing only from desktop. Should not be able to go anywhere where not know what to do. But not permanent, might need to fix machine if ever break.

Is there distro or config i can work off? Or need to start from scratch? What program you recommend?

Thank you for any answer or recommendation

I have a friend thats setting up linux (ubuntu) on his machine. He has a windows installation. I personally use mac as my primary OS, but I've had a linux partition on my machine as well, and I'm having a slightly hard time giving him good advice as to what solution he should choose when setting up linux (I don't even know how I would partition a disk on a windows machine to prep it for dual booting).

My question is quite simple: What are the pros/cons of WSL vs. Dual Booting vs. Virtualbox, both with regards to setup and with regards to usage?

Is it just me or did kdenlive broke for you too? I'm on an Archlinux based system and just updated the system. A few hours before update kdenlive worked. Update was not small, so its hard to tell the exact cause. I've tried to downgrade kdenlive, but same issue. I use Linux for a very long time now, but still get lost with errors like these.^^ Any idea what I should do? Does it work for you?

I get this on start (I reset the configuration files too):

$ kdenlive --version
kdenlive 24.08.1

I am running Bazzite 40 on a system with an RTX 4080. Up until yesterday, I was connecting computer -> Samsung HW-Q900C soundbar -> Samsung Q90C TV. I learned that the soundbar doesn't have HDMI 2.1 ports which is why I hadn't been able to get 120Hz, so I changed my setup to computer -> TV + soundbar -> TV (eARC).

Now, I do have 120Hz, but I lost a bunch of other options in my display settings, including HDR. The only options I can set there now are resolution, orientation, refresh rate, and scale. I suspect this is an issue with the TV communicating its capabilities in a way the OS doesn't understand, but I'm not sure how to fix or work around it. Can anyone suggest a fix? Is there a setting I can change on the TV or maybe an app I can run on the computer to manually set the TV's capabilities?

Update: Just discovered kscreen-doctor. Here's the output:

SOLUTION: Turns out this was my goof. I was trying to set up auto-login on my user account. In doing so, I set it to automatically log in to Plasma (X11) instead of Plasma (Wayland). Odd that the default option in that dropdown is not the one you’re currently using, but 🤷‍♂️.

What I’m now trying to figure out is why I can’t set auto-login for Plasma (Wayland). The Apply button is disabled. 🤔

Thanks to everyone who shared ideas.

In numbers, the LibreOffice 24.8.1 point release addresses a total of 89 bugs. Details about these bugs are available in the RC1 and RC2 changelogs. The new release is available for download right from the official website as binaries for DEB and RPM-based GNU/Linux distributions.

what is the best linux terminal? I have been using alacritty for years and have been doing well. But I don't think kitty and st. I was wondering if any new projects have come out in recent years.

What's everyone's preferred email client these days?

Sorry if this kind of question isn't allowed here, but I'm at my wit's end. VB randomly started launching on startup about 2 weeks ago (on EndeavourOS) and I can't figure out why. There's no shortcut in ~/config/autostart, it isn't in the KDE startup apps list, and I can't find anything virtualbox-related with systemctl either. There's also no setting in the VB app itself. WTF?

Based on recommendations in that thread, I also checked:

/etc/systemd/system
/etc/default/
vboxautostart.service
KDE "restore session" settings

Any ideas are much appreciated!
