Made the switch, videos play poorly

So I switched from Vista to Kubuntu and most things are going great. Video playing, however, is more than crappy. Using VLC or mplayer (with smplayer GUI) there is obvious tearing in the video itself. I've tried googling but have not found a fix. At first I also had video flickering but I fixed that by disabling desktop effects. Now I'm left with tearing, and I need my videos! If I can't fix this I guess I'm going back to Vista :(

PS: Using "xv" output in smplayer, however tearing happens on all outputs. I've enabled the ATI driver when the warning about it popped up after my first boot up.

Wow 1 star rating already, grow up :rolleyes:

Gotta love freetards. No help but they rate him low nonetheless. If VLC doesn't work off base install then somethings up. I'd say reinstall it or run it from the Live CD to see if it plays from there. If it does then defn re-install. Hopefully someone will help you out.

"freetards"? Troll much? (N)

Some people rate down any thread where "Linux" is mentioned. Just ignore the star ratings, I know that I don't pay attention to them.

Anyhow, you said you are using the ATI driver. Let's see if it is enabled. Post the output of the following line in a terminal:

glxinfo | grep rendering

(if you don't have your glx stuff installed, you may be prompted to try installing it first)

Not too sure about "xv", if that is the fallback lower-end video system or not. Someone more familar with mplayer may have to help you on that one.

Also, does it play OK when smaller like windowed? And only problems full-screen?

Not sure if this is all it's supposed to say but this is all I got :p

adam@adam-desktop:~$ glxinfo | grep rendering

direct rendering: Yes

adam@adam-desktop:~$

The xv is the highest output, using hardware acceleration. #3 in FAQ here. I've also tried the lowest (among others), x11, yet tearing is still there. VLC is set to "default", I have no idea what the defualt would be but it also tears. Happens in both windowed and fullscreen.

"xv" is the XVideo extension which is the normal (and accelerated) way to get video to the screen. It's what you should be using unless you have something way better (i.e. XVMC for MPEG2 playback, or VDPAU for new nVidia chips).

@OP: By tearing, I assume you mean that it's just display tearing, and you don't see any problems with decoding (your CPU can keep up with the video). If so, then it's probably not vsyncing. I can't help you much more since I'm not on Linux riht now and have no experience with ATI, but on nvidia chips, you can enable vsync for OpenGL and XV through the nvidia-settings program. There might be something comparable for your ATI chip.

Well it's a C2D and ATI 3650, not the best of things but plays HDTV transport streams flawlessly on Vista. In Linux decoding is fine, but the tearing is on everything... even on small DivX AVI files. The ATI Control Center is rubbish on my Linux, doesn't have nearly as many options as it did on Windows. It does have a "Wait for vertical refresh" option and I've tried it both on and off but no difference.

Have you tried enabling that option and using the gl2 output in mplayer? That might work.

Update your graphic driver, the left one did fix a lot of video player bugs, but accelerated video API is not availible yet to general public, ATI keep it in private beta for now, when they will add it to the official driver, performances will increase by neatly 1000% (if it is as good than when vidia introduced purevideo for Linux)

This worked! So ATI set to vsync on and "gl2 yuv" (the normal gl very choppy framerate) works great. I also had to update smplayer from their website because when I first got it (apt-get) it gave me an older version without the gl yuv option. Thanks for the help!

No problem. It's stupid that you're not getting vsync on xv, but I guess it's true, ATI drivers SUCK!

    • Secure Boot

      By cork1958 · Posted

      Simple answer is yes, you will still get the Windows updates and as long as browser is up to date, you will be good. Only thing secure boot does is protect you against boot level threats and make it harder to install other OS's. I've been looking into this pretty thoroughly lately myself as wifes computer has secure boot disabled plus my other, older computers that run Linux, don't have secure boot enabled. Have seen all kinds of questions about this on the Linux Mint and MX Linux forums. Just don't suddenly enable secure boot now.

      How many other companies will follow Ford's lead? Or, have they already gotten lazy and become enslaved to AI--and now can't figure out how to get out of that mess.

      Why would any self-respecting intelligent person follow any recommendation by Donald's GOP administration? With almost two years of fabrications, deceit, and blatantly illegal behavior, why believe them now? They had best be gone after the November 2026 election, so we'll wait and see.
    • AltSendme 0.4.1

      By Copernic · Posted

      AltSendme 0.4.1 by Razvan Serea AltSendme is a minimal, cross-platform application designed for fast, secure, and private peer-to-peer file transfers. It allows users to send files or entire directories directly between devices without relying on cloud servers, accounts, or any personal information. Everything is encrypted end-to-end using modern protocols like QUIC and TLS 1.3, ensuring both strong security and low-latency performance. Transfers are verified with BLAKE3 for data integrity, and interrupted downloads automatically resume, making the experience reliable even on unstable connections. You can transfer anything—images, videos, documents, and more. Integrity checks are performed on both ends, so your files are automatically verified for correctness during both sending and receiving. AltSendme works seamlessly across local networks or long-distance links, capable of saturating multi-gigabit connections for extremely fast delivery. With built-in NAT traversal and encrypted relay fallback, it connects devices almost anywhere. The app integrates with the Sendme CLI and will soon support mobile and web platforms. Fully free and open-source, AltSendme offers a lightweight, privacy-first alternative to traditional cloud-based services, removing size limits, upload costs, and unnecessary data exposure. AltSendme 0.4.1 changelog: Release Highlights Self-hosted relays: Run your own iroh relay so transfers don't rely on public infrastructure. Includes a full deployment template in deploy/relay/ with Docker Compose for a VPS and configuration examples for production use. Fly.io support: One-click deploy template for Fly.io, including a quick-start config (fly.dev.toml) for testing without a custom domain, plus production setup with Let's Encrypt and your own hostname. Relay settings UI: New Settings → Network panel to choose how AltSendme connects: automatic public relays, custom self-hosted URLs (with optional auth token), or disabled. Test connections, verify latency, and see live relay status in the footer. Disable relays: Turn off relay servers entirely when you only need same-network transfers (e.g. LAN). Direct connections only. No relay hop required when devices can reach each other. Android graduates from beta: Android is now part of the regular release cycle alongside desktop. APKs ship with each version (universal, arm64, and armv7). Other improvements Private relay access control via shared auth token Relay fallback notifications when a custom relay is unreachable Broadcast mode toggle in sharing settings Android release build fixes (split-per-ABI APKs, universal APK preservation) UI polish: mobile safe-area insets, dropzone layout, transfer progress animation Bug fixes for minification-related serialization issues and system tray icon loading What's Changed feat(relay): add relay status functionality and settings UI (a120cdf) feat(relay): implement custom relay server configuration and verification (51276c7) feat(relay): add configuration for private relay access and enhance observability features (48fbabf) feat(relay): enhance relay URL validation, display connection status (d4fffa0) feat(relay): add RelayChangeGuard component and enhance relay-related translations (16ba514) feat(broadcast): add toggle setting for broadcast mode in sharing UI (ca6d977) fix(relay): correct QUIC discovery port, pin image, templatize fly.dev (52a2ba5) fix: More broken serialization due to minification (67491a9) fix(android): preserve true universal APK across per-ABI builds (e9f256f) fix(ui): conditional safe-area insets padding on mobile (1182f0e) refactor(transfer): CircularRing component animation fix (944572b) chore(android): drop x86 and x86_64 release APKs, keep universal+arm64+armv7 (34ada0b) Download: AltSendme 0.4.1 | ARM64 | ~9.0 MB (Open Source) Download: AltSendme for MacOS | Android Links: AltSendme Home Page | GitHub | Screenshot Get alerted to all of our Software updates on Twitter at @NeowinSoftware
    • Why Delta Chat is the best decentralized messenger you have probably never tried

      By zikalify · Posted

      You are mostly right about the ephemeral nature of it. As I mention in the article, if you dont add a second device or take a backup of your account before uninstalling it, then yes you will lose access to your account. That said, in terms of actual user experience when you sync multiple devices your message history carries across and there's also a Saved Messages chat like there is on Telegram to send messages and attachments between your installs. But yh, what you point out are correct and its not trying to emulate Messenger or Telegram.
