If i try to start Gutsy not in recovery mode X never starts, and there is no way to interrupt the process, that does not let you do anything than push the reboot or shutdown button of the CPU. So I always start Gutsy in recovery mode and wathching the kernel until y get the message like " give root password for maintenance " and then i press Control D, and if i do not use control+ alt+backspace I get the same problem than booting not in recovery mode.
I think that way I do is not a good way, but it is the only way i could think to resolve my problem and i really want to use direct rendering, so, if i do not do that, i cannot do a lot of thing like playing some games and use Compiz.
I discovered so many people with the same problem than me, not only in KDE, ( I use KDE ). Anyway I browsed this page and I do not think this bug is duplicated somewhere. If it is, please let me know, or a way i can help to fix it. Thank you.
I really dont know if the reason of this was compiz, but the problem appeared after i installed it, or kde or xorg.conf, because now in hardy alpha, i tried to modify xorg.conf and using kde gnome or xfce, and disable glx in xorg.conf. But all tried did not work, i saw other bugs related and did some things like modifying driver nv, for vesa or vga or nvidia. At this time i am really lost about what to do.
