I have the same problem (with a ATI Radeon 9200 Pro) on my Ubuntu "8.10", then "9.04" : "on a fair percentage of boots (around 40-50%), the machine appears to hang with a black screen immediately after the splash screen progress bar fills up".
On Ubuntu "9.04", sometimes, the screen is not black but contains pseudo-random datas (I can recognize the wallpaper of precedent boot). An interesting point is that the problem appear since we change the kernel "2.6.24-23". In fact, the problem totally disappear every time I boot with the old kernel "2.6.24-23". -- Ubuntu 9.04 gives black screen after splash, remote login shows hung/unkillable gdm instance https://bugs.launchpad.net/bugs/370111 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
