Tested the temporary fix for blackscreen, no ttys, no usplash in the installed system based on this bug:
https://bugs.launchpad.net/ubuntu/gutsy/+source/ubiquity/+bug/150930/comments/65 Which results in normal splash with tty's, and obvious absence of black screen. Only difference here, is I made manual changes to usplash.conf instead of using startupmanager. It is no longer necessary to strip quiet and splash from the kernel boot parameters with the fix. ** Description changed: The LiveCD boots normally to the initial splash screen with menu options. After selecting any option, the screen goes black with no backlight and remains that way. X never appears to start. The hardware specific to this bug report is a Dell Inspiron 1420. Detailed report for Gutsy can be found here: https://wiki.ubuntu.com/LaptopTestingTeam/DellInspiron1420 Under the hood are: intel core 2 duo t7500 nVidia GeForce 8400M GS The normal kernel bug reports will be attached following the report, along with a comparison of LiveCD results for Feisty, Gutsy, and Hardy Alpha 1. This bug may be similar to #147623 and #67079. The bug has occurred in every daily version of Hardy as well as the - Alpha 1 release. The last one tested was 12152007. Gutsy at least + Alpha 1 release. The last one tested was 12182007. Gutsy at least failed over to displayconfiggtk. Their are only two resolutions found so far: 1. Remove 'splash' from the LiveCD kernel boot parameters. 2. Insert break=top, then when the busybox shell pops up, enter: modprobe vga16fb The second method does not result in a splash screen, but the LiveCD will boot into X without user intervention. I was unable to reproduce this in any other distribution, as I don't personally know any other that uses usplash. I tested a debian installation, but they are using directfb during initial installation for a gui. i386 can also be installed on the specific laptop, but also results in the same problem, at least with the Alpha 1 release. This was not tested with additional daily versions. I wasn't sure whether this was a casper, usplash, or linux problem, but allowed the wiki.ubuntu.com/Bugs/FindRightPackage to lead the way. If there are any further questions after this initial report, I will promptly answer them.
