Great work, Jerry. I actually misread your description in that I thought you had access to a VT after the black screen even when running with the intel driver. Great that you were able to get an Xorg.0.log anyway.
Usually when a black screen like that happens, the computer is not completely dead, only the keyboard and mouse. This leaves the network interface. If you have another computer and a home network and another computer available, you may be able to ssh in after the computer looks otherwise dead. Since this is a LiveCD, it is a bit cumbersome but not too hard. You have to start using recovery mode as before, and then install the package openssh-server. You then have to create a user that you can log in as (or simply set a (good) password for root). Test that you can log in from the other computer before you start gdm and trigger the bug. You may now be able to copy files and do some debugging. If xorg crashes, there should be a short backtrace near the end of Xorg.0.log. In that case we would like you to get a full backtrace (see https://wiki.ubuntu.com/X/Backtracing). If there is no backtrace this may be a freeze (GPU lockup). In this case, we would like you to take a GPU dump. For this you need the package intel-gpu-tools. It has a program called intel_gpu_dump which will dump the registers of the GPU to STDOUT, so `inter_gpu_dump > igd.txt` should give you a file to upload here. I'm a little worried that you can't use the VESA driver. Maybe you should file a bug for xserver-xorg-video-vesa as well. Or there could be an underlying problem.... Actually, I think I just include xserver-xorg- video-vesa in this bug report for now. ** Also affects: xserver-xorg-video-vesa (Ubuntu) Importance: Undecided Status: New -- [i845g] karmic CD Live black screen i840 video https://bugs.launchpad.net/bugs/385947 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
