Xorg on full CPU load with nouveau and NV34 chip (GeForce FX)

Hi folks,

for lack of a better alternative I used to run an old GeForce2 MX200 in one of my Arch machines. Graphics were pretty smooth for the daily non-sophisticated work. Watching YouTube videos fullscreen was a bit of a challenge, but vlc and ffplay rendered videos smoothly up to 720p.

Now I found a GeForce FX 5200LE (NV34), which is great since I always wanted to test TV out and nouveau supports it for the NV30 chip family.

But now even with TV out diabled Xorg sometimes takes up a very huge CPU load e.g. when moving windows, rendering simple shading effects like the “tab page” in Firefox or sometimes even when doing simple stuff in urxvt. It’s really annoying.

It there any chance to fix this via a custom Xorg configuration?

Here’s the Xorg-Log: http://pastebin.com/J9JgTsr3

What video card driver are you using?

What is the output of "glxinfo | grep rendering"? Are hardware accelerated graphics "direct rendering" enabled?

What window manager / desktop environment are you using? Are you using a compositor?

It’s nouveau as mentioned in the thread topic.

direct rendering: Yes

What window manager / desktop environment are you using? Are you using a compositor?

Openbox. Compositor? I don’t think so. Never installed one intentionally.
