It seems there are some incompatibilities with some video drivers, particularly (not surprising) some ATI and nVidia. Seams that they are not able to generate such a description, or rather to solve this problem in total with Canonical or NVIDIA, for all the other users which are having this problem.There have been a number of reports regarding blank screens at startup pre and post installation on the new Ubuntu 10.04 “Lucid” release. After many “Try this link”, “do that”, they’ve sent me the link to your instructions. And once again I’ve asked the Dell support how to solve this. With help of a forum I found out that NVIDIA is the reason. Also I’ve asked for a Dell specific image for installation, but for both I’ve got a “NO”. I’ve asked if there are special drivers necessary. My support request with Dell has gone over weeks. Since it isn’t described 100 %: Before and after “nomodeset” there shall be a blank or rather space to the other words (no idea if it’s really required, but initially I was unsure if or if not). That’s because I’ve knowed that the NVIDIA grafic is the reason for the black screen after login, I’ve installed the propriete driver from NVIDIA after the successful login.Īfter installation and rebooting the system (then without the modification “nomodeset”), after the login, the desktop has appeared as it shall. I’ve not performed both sequences, only the temporary fix. So my solution will be to have the old kernel and see if next will fix this, and look for bug reports at With the nomodeset, the new kernel boots, but only with the 1027×768 resolution. With the older kernel, it works as it should with full HDMI resolution. With the new kernel the system halts, with black screen and not responding to anything.

Locate the line with the variable “GRUB_CMDLINE_LINUX_DEFAULT”, and add “nomodeset” to the variables. ![]() Either “su” in to root, or use “sudo” to open your favorite text editor and edit the file “/etc/default/grub” (I use nano which can be install by running “apt install nano”): nano /etc/default/grub.Open a terminal window (Applications -> Terminal, or press the “Start” button and type terminal).Once the system has booted using the temporary fix, log in.Feel free to remove “quiet” and “splash” for more verbosity to troubleshoot the boot process. ![]()
