It has nothing to do with using conky. You are probably running compiz.

Adam

Yeah , i have installed compiz ..
How can i disable compiz ? Not remove it , but not automatically start up.

LIBGL_ALWAYS_INDIRECT forces all rendering to be indirect which is why you are seeing "direct rendering: No". Unset that env var, and you should get direct rendering. Note that you can still get hw acceleration with indirect rendering; indirect just means the 3d commands are sent to the xserver via GLX and then from the xserver to the 3D driver rather than send to directly to the 3D driver.

Greatly appreciate

You have disabled direct rendering. Most likely you are running some window manager that requires LIBGL_ALWAYS_INDIRECT to be set, and spawned a terminal from that window manager.

If you run a terminal from your gnome menu, does glxinfo report direct rendering? Your renderer string is correct, so I'm willing to bet that everything is fine.

Adam

Ah..... That's right...
When i open the terminal form the menu , the result is :
~ > glxinfo|grep render
IRQ's not enabled, falling back to busy waits: 2 0
direct rendering: Yes
OpenGL renderer string: Mesa DRI R600 (RV620 95C4) 20090101 x86/MMX/SSE2 TCL

but if i open a terminal with keyborad shortcuts, that is , "win+T"
the result is "no" again ..

also i use conky ? this affects?

[tuantuan]

Sure, but wait a minute , i restart and then switch to ubuntu
