Do you use browser as a flatpak? Are you aware of the weakened sandbox of the flatpak version? Title. I'm kinda on the edge to start using Firefox as a flatpak, cause I can get codecs and hardware acceleration for my GPU. I know about the weakened sandbox of the flatpak Firefox, but on the other hand Mozilla is actively developing it and it is a standard for example on RHEL nowdays. Am I thinking this too far? Is the weakened sandbox really a big deal? https://redd.it/1xgaooa @r_linux

New Linux user trying FSR 3.1 and GameScope in RDR2 (https://www.reddit.com/r/linuxgaming/?f=flairname%3A%22guide%22)Hi, I recently switched from Windows to Linux as my daily drive. I picked Fedora since it supports secure boot, and I can still boot into my Windows and play League of Legends (the only thing keeping me there). Other than that, it's been a smooth ride. This is not my first attempt but this time I did something different that I hadn't done those other times, I thought lets use my claude subscription to handle things for me and so I did and it's been insane how fast it fixes all the potential problems and installs my drivers and finds the settings I want quickly for me, although it might sound bad I've asked it to track every decision and command it runs in my machine in a private repo that I ask it to keep updated everytime so I have some kind of changelog of my machine but over all very smooth experience. I thought, "Well, why not let it install my game, Red Dead, and optimize it for me?" That's when I found out more about FSR and game scope; it searched for the recommended settings for my machine and gathered information from different community pages, and the result has been insane for me. I have a flashed RX 5700 -> RX 5700 XT. I could play Red Dead Redemption on it with decent quality at 1440p (sure it's upscaled) and hit 190! FPS at times, it's phenomenal. I've never seen my card hit these numbers, and to be honest, I'm happy with the quality of the game even though it's upscaled and I have fake frames. It's such a smooth experience, and my card has gotten a totally new life. I tried several other games and had the same experience everywhere. I thought I would make a video and record my gameplay and put it on YouTube so people can watch it and use the settings as well. If you have any questions, hit me up. https://www.youtube.com/watch?v=ivDFitbCoSY This is the reasoning on how this was possible (AI response): RDR2 does not support FSR 3.1. Out of the box it only has FSR 2 (added in a 2022 patch) and DLSS 2, and no frame generation at all. The secret sauce is a mod that fakes it. 1. OptiScaler: the main trick \- It's a small DLL dropped into the game folder (winmm.dll, with the Wine override winmm=n,b). \- When the game calls its built-in FSR 2, OptiScaler intercepts that and runs FSR 3.1.4 instead, which is a better upscaler. \- It then adds FSR 3.1 frame generation on top: it hooks the game's frame output and inserts a generated frame between every two real ones. That roughly doubles the number on the counter. \- Frame generation only works in DirectX 12 mode, not Vulkan, so the game runs in DX12. 2. Upscaling from a low internal resolution \- FSR 2 is set to Performance in the game, so it renders at only 1280x720, and FSR 3.1 rebuilds that to 2560x1440. That's the biggest real-fps gain. 3. Smart settings \- Ultra textures, which cost almost nothing on an 8 GB card. \- Shadows and lighting on Medium, the most expensive settings. \- Volumetrics and GI on High, motion blur off, VSync off. 4. The Linux side \- GE-Proton 11-11 with vkd3d-proton turns DX12 into Vulkan. \- RADV_QUEUE_DISABLE=compute avoids the RX 5700's GPU-hang bug. \- vulkan-1=b fixes OptiScaler crashing on Rockstar's old bundled Vulkan file. \- gamescope runs at native 1440p with no extra scaling. \- GameMode keeps the CPU at full speed. https://redd.it/1xgdcyf @r_linux

Lenovo Yoga Pro 7 14ASP9 (83HN): dead "Digital Microphone" fix /r/Fedora/comments/1xg5145/lenovo_yoga_pro_7_14asp9_83hn_dead_digital/ https://redd.it/1xg59fy @r_linux

Fixed random full-system freezes on NVIDIA (open driver, Wayland) by enabling Resizable BAR on anold X99 board For a while my PC froze about twice a day. Not a crash I could recover from: the screen stopped, audio sometimes kept going, and even Ctrl+Alt+F3 did nothing. Only the reset button helped. Setup: CachyOS, kernel 7.3.0, niri (Wayland), RTX 4060, nvidia-open 615.78.08, Huananzhi X99-BD4 motherboard. After a reboot, `journalctl -b -1 -k` showed the same pattern every time: NVRM: dmaAllocMapping_GM107: can't alloc VA space for mapping. NVRM: nvAssertOkFailedNoLog: Assertion failed: Out of memory [NV_ERR_NO_MEMORY] NVRM: Xid (PCI:0000:03:00): 56, ... NVRM: krcWatchdog_IMPL: RC watchdog: GPU is probably locked! The process that hit it first changed. Once it was a Godot game I'm developing, twice it was Brave (its Media process died with SIGILL right before the lockup). So it wasn't one bad app. `nvidia-smi -q | grep -A3 BAR1` showed the problem: BAR1 was only 256 MiB. Without Resizable BAR, the driver maps GPU memory for the CPU through that small window, and when it fills up, the open driver can lock the whole GPU instead of just failing that one request. There's an open upstream issue with the exact same logs from people on Fedora, Bazzite, Arch and CachyOS, mostly with Chromium-based browsers or Discord as the trigger: [https://github.com/NVIDIA/open-gpu-kernel-modules/issues/1396](https://github.com/NVIDIA/open-gpu-kernel-modules/issues/1396) My BIOS had "Above 4G Decoding" but no Resizable BAR option. It turns out Huananzhi publishes an official BIOS for the X99-BD4 with ReBAR added, on the board's download page. I flashed it, enabled Above 4G Decoding and Re-Size BAR, and now: BAR1 Memory Usage Total : 8192 MiB No VA errors in the kernel log since, no freezes, and the whole system feels smoother, including games. If you have an NVIDIA card on an older board and see "can't alloc VA space" before a freeze, check your BAR1 size. A lot of X99 and other older boards have official or community BIOS updates that add ReBAR. Flash carefully and only the file for your exact board model. If you can't enable it, people in that issue report that turning off hardware acceleration in Chromium-based browsers makes it happen much less often. https://redd.it/1xg5kz0 @r_linux

Panfrost's new Kraid compiler becomes the default for Mali Valhall GPUs in Mesa 27.0 Faith Ekstrand's write-up on Kraid, the new shader compiler for the open source Panfrost/PanVK drivers: https://www.collabora.com/news-and-blog/news-and-events/panfrost-is-now-using-kraid.html Starting with Mesa 27.0, all Mali GPUs with Valhall (v9) or newer will use it by default. Mesa 26.3 is the last release with the old compiler. Highlights compared with the old compiler: \- \~18-20% fewer shader instructions across OpenGL and Vulkan shader sets \- Over 80% less register spilling \- Proper 64-bit integer support \- Much faster shader compilation with lower memory use It went from start to default in under six months! https://redd.it/1xfxig8 @r_linux

TIL Brazil's Voting Machines use Linux! https://preview.redd.it/lzs3j94k4txh1.png?width=806&format=png&auto=webp&s=d2eccc9e1a8df3976a7e8918115802fdc958029f The original operating system was VirtuOS, similar to MS-DOS and includes multitasking support, was developed by Microbase. It was used in the 1996, 1998 and 2000 elections. In 2002, Unisys was unable to renew their partnership with Microbase, and were unable to reuse the VirtuOS based code. Microsoft stepped in, and provided licenses for the Windows CE operating system free of charge. In 2008, under initiative from the TSE Electronic voting team migrated to a Linux (dubbed UEnux) OS to reduce costs and take full control of development cycle. \- From Wikipedia Thought this was a fun thing to share given yesterday's elections and how fast the votes were tallied. https://redd.it/1xfvr5t @r_linux

Fogu: a native Rust terminal, batteries included Hi all! Fogu is a terminal for people who spend their day on remote servers. Batteries included means your ~/.ssh/config hosts are in the sidebar, the SFTP panel works on the same connection as your shell (already in its current directory), port forwarding is built in, and passwords go in the system keyring. Nothing to add on top, and it opens in about a tenth of a second. It runs on Linux and macOS (Windows is alpha). MIT licensed. https://github.com/Revdep/Fogu \-> screenshots provided Big thanks to Tabby, which inspired the whole SSH + SFTP workflow, and to Alacritty, whose alacritty_terminal crate powers Fogu's terminal emulation. Feedback very welcome, the harsh kind too. P.S. Fogu is still young, so think of it as a beta: I use it every day, but expect rough edges and some config changes before 1.0. Issues and PRs are very welcome! https://redd.it/1xfsfcu @r_linux
