My X600 mobility is working better than ever using: Acer Aspire 5021Wlmi 1GB Ram 32 bits Ubuntu distribution installed in 64bits AMD processor
Direct rendering is activated and glxgears show arroud 1900 fps, flurry and openGL screen savers go faster than in any other version of free drivers. Just with the clean default installation of Edgy. So maybe is a computer configuration problem more than a graphic card one. -- Very bad performance with X600 in Edgy https://launchpad.net/bugs/62768 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
