[solved] Laggy Video

adamlogan · 2010-10-09 08:14:44

I don't understand why video is lagging again. It went away when I installed intel-dri a month or so ago. But after a full system upgrade it's all laggy again. According to pacman intel-dri & xf86-video-ati & ati-dri are all installed. What could the problem be? I'm on a older ibm thinkpad, it's not built for heavy duty graphics but low quality youtube videos should not be lagging either.

480p will be the max you can watch on youtube asuming you have a pentium-m 1.4 or similar. You might be able to watch 720p if you use mplayer instead of flash to watch it.

What gfx card do you have btw?

edit: even some 480p youtube vids might lag, depending on the encoding.

Well in the past the Thinkpad has played 720p films fine in VLC. I usually do 320p for youtube just cuz bandwidth does not exceed 64kb/s here and I don't see that much of a difference. It did not lag in the past month or so, am wondering why it's lagging now all of a sudden. The gfx card is Radeon Mobility M7 LW AKA Radeon Mobility 7500 according to lspci | grep VGA. Using openbox, X-ORG without custom configs, Vesa drivers installed (forgot to mention that before). Youtube videos are all in flash right? I have adobe flash installed. Can Mplayer really handle that format well? What about VLC? hmm. Still I don't see what's wrong. In the past when the video was laggy all I had to do was install intel-dri and all of a sudden problem was solved. It's still installed so I'm scratching my head.

I have a T41 with a M6 card, (even slower, it's a r7000), and most 720p plays fine in mplayer, with a few exceptions. (usully due to bad encoding, or really fancy softsubs). Intel-dri shouldn't make a difference at all, it's not a intel card after all...

Do you have kms enabled or not?

Thanks, didn't know about kms. Found it on the archwiki, enabled it, seems to have fixed the laggyness. Cool. So as a result of using KMS the downside is no framebuffer stuff?

Arch Linux
