Comment 0 for bug 755791

Binary package hint: xorg

I installed Ubuntu 11.04 Beta 1, and I'm not able to run Unity and Compiz, because I have no 3d acceleration. However, I was able to run Compiz once, the next time I booted, I don't know why, Compiz doesn't work. After several reboots, I see the following:

1. Sometimes (?), I have 3d acceleration via software rendering. When I run `glxinfo | grep render` I get:
direct rendering: Yes
OpenGL renderer string: Software Rasterizer
    GL_NV_conditional_render, GL_NV_depth_clamp, GL_NV_fragment_program,
And if I run `compiz --replace`, I get the following error:

Backend : gconf
Integration : true

2. Sometimes, I have direct 3d acceleration, but it's unusable. glxgears doesn't work (black window). Also, if I run compiz, I get a blank screen (no Unity, no windows, just the mouse pointer and the background image). In this case, if I run `glxinfo | grep render`, I get:

direct rendering: Yes
OpenGL renderer string: Gallium 0.4 on ATI RS690
    GL_NV_blend_square, GL_NV_conditional_render, GL_NV_light_max_exponent,

So, I'm using the Gallium driver. I had a similar problem with Maverick and the radeon driver. I solved the problem turning off the Kernel Mode Setting (# echo options radeon modeset=0 > /etc/modprobe.d/radeon-kms.conf). I don't know how to do that with the Gallium driver. I want also to try using the radeon driver, but I don't know how to do it.
