Hi Laurent, thanks for the help. I attache the glxinfo output, but looks nothing relevant. I know radeon driver is experimental, but, cannot run xgl on feisty due ATI propietary does not support composite in last releases (8.33 I think). So, for now, only AIGLX is possible. I have tested with liveCD, running same config, ndiswrapper with no acpi problems, radeon driver, beryl running, and runs.... incredibly well, much better with kernel 2.6.20, thats why I wanted to check that. I am pretty sure is a problem with fglrx package removal. When I removed it, aptitude crashed with the purge. I removed all /usr/lib/liGL*.so so.1 etc... and reinstalled all libgl mesa packages... but... nothing solved. I wonder what I am missing. That why I suspect is somthing related with the 8.33 xorg-driver-fglrx package...
Any ideas? ** Attachment added: "glxinfo debug output" http://librarian.launchpad.net/6454106/glxinfo%20debug%20output -- AIXGL ATI Mobility Radeon X700 freezes with glxgears, glxinfo reports no rendering, radeon driver used https://launchpad.net/bugs/85557 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
