There's no 3d support in Xvesa. Install and configure the Xorg extension to get it, and to get rid of that error.

Tried.

Run Xorg -configure and tested the created config file. Many error messages:

Unable to open /dev/agpgart
Module i915 not found
...

There are no such modules. /lib/modules/.../kernel/drivers/video is nearly empty, only backlight module is there all others are deleted.

Searched repository but did not find extra modules, maybe I missed.

The info file states

Quote

...
   This extension depends on graphics-2.6.29.1.tcem for
      any kind of 3D or video accel.
.
      Please note, for AGP or integrated AGP cards such as Intel
      chips you will always need graphics-2.6.29.1.tcem.
...

Since you're after 3D, and have an Intel card, have you loaded this extension?

edit: It is not a default dependency because many people will only look for improved 2d and the (much better) keymaps.

Thanks pointing to this extension, I missed it. I will play with the setup now to configure it properly.

Software 3D works fine with Xorg. Hw acceleration starts but need some more configuration, screen resolution is too high.

I don't know if it's related to the same problem, but I'm getting a similar message:

Xlib: extension "Generic Event Extension" missing on display ":0.0"

happens in terminal and emelfm when I launch something.

That warning is safe to ignore.  If you want that extension, something like the Xorg extension can be used.
