Two answer one of your questions, the gallium driver does not have a
non-KMS mode, so the modeset=0 workaround isn't available there. (With
some work you may be able to revert to using the non-gallium radeon
driver, but let's focus this bug report on fixing the bug itself.)
** Description changed:
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,
+ 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
Profile : default

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

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.
