Public bug reported: I am following this link:
https://wiki.ubuntu.com/X/Troubleshooting/BlankScreen This seems to only happen after I switched to UEFI booting from normal booting on the same computer with the same hardware and same OS version. The problem (I think) is happening in step 6. I don't think this is an xorg bug but I don't know what package this goes with. Every so often I will turn on my computer, it will boot, and not display a splash screen. I changed boot parameters in /etc/default/grub to GRUB_CMDLINE_LINUX_DEFAULT="drm.debug=0x4 plymouth:debug" It will boot and display a mess of startup text like normal. It will then pause for a second, the text on the screen will change (I think it is switching resolutions), it will flicker and die. I get a black but active screen. The LED on the monitor doesn't denote inactivity but active and black. Here is the output of /var/log/plymouth-debug.log. I turned on debugging and had to reboot 4 times before the screen wasn't black. This bug is almost always reproducible. Oh, of more interesting note, I added nomodeset to the startup but that played havoc with unity. I had a gray or black bar on the left section of the screen where the application bar hides and nothing could overwrite it fully. I could have a cursor light up a few characters in this section but withdrawing the window from this section turned it back to solid gray. However, it did boot flawlessly.
