Bug Description
Right after grub is loaded, the screen goes black. The boot process goes normally however. I can enter my session and shut down the computer like I would with eyes closed, knowing what keyboard keys to hit.
Display is back on when selecting a recovery session, like this one, i.e. a Xorg session (otherwise I could not report this). Same Xorg low graphics occurs when adding nomodeset to grub parameters, which gives me a 1920x1440 display instead of 2560x1440.
PLease note that the grub parameter "acpi_backlight
I do not know if this will help, but note that I have always had problems with the graphic card. After sleep mode the display always comes back at full brightness no matter what low settings it was before the sleep mode.
