I didn't remember changing anything, but now when I open my web browsers like Chrome or Opera, or use MPlayer to play a video, the whole desktop will lag, very seriously. When Chrome is open, CPU usage is around 34%, and it will immediately drop to 3% when I minimize it (Everything will be normal then).

I'm using XFCE4, kernel 3.18.1

I think it's a problem related to some hardware acceleration or video drivers, but I don't know how to fix it.

Here's the messages file: http://pastebin.com/8yhsJekb

shanehou ... it may help to disable compositing ...

Code:
$ chromium --blacklist-accelerated-compositing

See this link for other possible parameters.

As for mplayer ... is your x11 accelerated, what -vo is used, and what is the video quality of the video in question?

HTH & best ... khay

Any videos, even a 320x240 wmv video. If I make it fullscreen, it will lag more seriously.

What did you mean by "what -vo is used"?

Sometimes, if I open a window without minimize Chrome, contents in that window will be fine.

And keyboard sometimes misorders my input.

I've tried to add all the params in that link, but nothing turned out better.

shanehou ... I mean mplayer's 'vo' (video out) ... you can probably run 'mplayer -vo help' to get a list of video outs supported by your build of mplayer (thats from memory, it may be 'vo'). So, for instance are you using vo=opengl, or vo=xv, etc.

It's gl_tiled, and I changed it to gl or x11, but nothing changed.

shanehou ... ok, so are you using an accelerated framebuffer? Does 'glxinfo' show opengl as enabled, and what is 'eselect opengl list' set to?

eselect opengl list was set to x11-org and glxinfo output is http://pastebin.com/R42nKjuw

I changed MPlayer vo to x11, and somehow it became normal! And I found "Use hardware acceleration when available" setting in Chrome and disabled it, and Chrome is normal now!

I think it's some issues related to opengl.

shanehou ... yes, and it seems there is another poster with the same chipset (ironlake) and the same symptoms.

With the new xorg-server update and mesa update, came a lot of issues:
The new xorg-server stable caused my x server to crash the first time I try glxgears after a cold boot (this may be due to no acceleration as I mentioned here --> https://forums.gentoo.org/viewtopic-t-1006772-highlight-.html). After that, if I go back into xorg, glxgears works fine and it has video acceleration.
The new mesa stable update fixed this problem.
However, it caused my x server to crash the first time I tried opening chromium after a cold boot. Same thing; I restart xorg and it works fine.
Because I didn't want my work to be lost by accidentally opening chromium or forgetting to restart xorg, I decided to use the unstable version of xf86-video-intel.
I am currently running version 2.99.916 of xf86-video-intel.
So far, none of my applications causes my xorg to crash with or without video acceleration. However, my vlc won't play videos (audio only) without video acceleration.
:/

And I'm not sure what fixed this, but before if I put my laptop to sleep, if I wake it up again, leave GUI and come back, I get a blank screen. Now I am able to go back into xorg after a suspend to ram.
