I removed MUTTER_DEBUG_DISABLE_TRIPLE_BUFFERING from the
/etc/environment file and the system booted properly. But when I removed
the other line MUTTER_DEBUG_USE_KMS_MODIFIERS=0 the issue reappeared. So
adding  MUTTER_DEBUG_USE_KMS_MODIFIERS=0 in the /etc/environment file is
the present work around for this issue. I wanted to pass this info to
the other members who are facing this issue so that atleast they can
move forward and use Gnome until the bug is fixed. So far I have seen no
work around posted anywhere so put it here. Members please do confirm if
this work around helped.

Title:
  Black screen with nouveau after system update

Status in linux package in Ubuntu:
  Incomplete
Status in mesa package in Ubuntu:
  Confirmed

Bug description:
  Ubuntu 24.04.01 LTS updated today using "software updater". Since the
  update the PC just boots to a black screen. It worked fine before the
  software updates. I have managed to get a usable screen (but wrong
  size etc) with online help using Esc key on bootup. But the bug
  persists when the PC is restarted. I have an NVIDIA GT218 graphics
  card and Ubuntu tells me that "all available drivers are already
  installed".
