[Bug 664526] Re: setting nomodeset in grub, if live session was started with nomodeset

[Pierre]

Would someone kindly answer that...

I was just working on the nomodeset issue, trying to replace in the
Lubuntu Raring ISO boot menu the second option--INSTALL LUBUNTU--by TRY
LUBUNTU WITHOUT INSTALLING (NOMODESET).  I changed the option's title
and added the 'nomodeset' to the boot parameters of the appropriate line
in the isolinux/txt.cfg from which the boot menu is drawn.  E.g.

1) TRY LUBUNTU WITHOUT INSTALLING (NORMAL MODE)
2) TRY LUBUNTU WITHOUT INSTALLING (NOMODESET)
With these boot paramaters:
  kernel /casper/vmlinuz
  append  file=/cdrom/preseed/lubuntu.seed boot=casper initrd=/casper/initrd.lz quiet splash nomodeset --


This way, it would be easier for new users with the NVidia problem to test & install the distro.  

The question: If people decide to install, would the 'nomodeset' boot
parameter be transfered by Ubiquity to new installation just as if
someone had pressed F6 and selected 'nomodeset' to boot up with the ISO?

Second question: The nomodeset paramater is before the --.  Should the correct boot parameters be this instead:
  append  file=/cdrom/preseed/lubuntu.seed boot=casper initrd=/casper/initrd.lz quiet splash -- nomodeset


Thanks.

Bug description:
  Binary package hint: ubiquity

  Posting this as bug because I want to nominate it for 100 papercuts.

  Some machines require nomodeset option to boot in to the GUI. For that
  reason, the livecd has this option more or less  (*) conveniently
  accessible from the boot menu, using F6 key.

  However, when this option is selected for the live session, ubiquity
  will install ubuntu and  not set "nomoset' as default  option. As a
  result, the machine will reboot and the user will unnecessarily almost
  guaranteed  again face a black screen, and this time, with no F6 menu
  to solve it, instead this time requiring  complicated grub editing in
  a menu that is again hidden by default and not even a clue there is
  one (grub), and then more advanced editing of grub defaults. This is
  an impossible task for any new user, and a unnecessary one.

  If the live session is booted with nomodeset (and possibly other
  settings like safe graphics), ubiquity should recognise this and
  either set those same settings as default, or prompt the user and ask
  if he wants to retain those settings for his install  (and it should
  default to yes).

  (*) IMO  its "less" rather than "more"; that menu on the livecd is
  hidden too well  for a new user. Ive been using ubuntu for years and I
  didnt realise the keyboard logo meant I could press a key to open a
  menu. Why arent these options available in the menu where you select
  language and keyboard? Just have an "advanced" button or something.
  But thats another issue I suppose.
