Hi
have been wanting to upgrade to a later version (from 9.10 upwards) so
decided on 11.04.
Downloaded ubuntu and tried to run it off a USb stick (after setting
up the bios etc).
The system would reach the casper thingy stage and after a series of
dots the screen would blank out and the medium and HD would cease any
activity.
Tried it with a bootable USb stick, bootable cd / dvd . Zilch same
stage it would get stuck.
Tried 10.10 and the same thing happened. (so it seems this bug has
been around since then)
After googling and reading around found that it may be one of the
following two issues
1. USB booting isn't really supported and having set bios up to boot
from USB it was causing problems -
disabled usb booting - result - same thing no go after casper and company
2. The ATI X1300 graphics card (as on my machine) and nvdia and intel
graphics cards are not being properly read by the kernals in 10.10 and
later (not sure which specific ones but definitely the ones later than
2.6.32.x onwards
The fix is quite straighforward , and simple if you pay attention to
the minor details
when the live boot grub menu comes up press tab
you should see a prompt with lots of stuff written , which ends in --
(two dashes)
this allows you to manually enter some options
find "quiet" and "splash" and change to "noquiet" and "nosplash" and
also type out "nomodeset" - all of this has to be before the --
depending on which graphics card you have difference commands might work
nomodeset is generic but also specific to nvidia cards
or to be more specific
* For ATI chipsets: radeon.modeset=0
* For nVidia chipsets: xforcevesa or nomodeset
* For GeForce and Generic: nouveau.modeset=0
* For Intel: i915.modeset=0
but you can see this thread to know what code to use

Once the install is done , what next, you aren't home free yet Because
the same blank screen issue will pop up on first boot
What is needed now is to hack the /boot/grub/grub.cfg file
There are two ways to go about it - one - just after the install
finishes instead of rebooting one must mount the partition where the
new / (root) or /boot is and navigate to
/boot/grub/grub.cfg
before you edit the grub.cfg make sure you make a copy name it
whatever you want , as suggsted grub.cfg.old seems nice
open grub.cfg with your editor (in sudo mode) - i use gedit
like -$ sudo gedit grub.cfg
then find the lines that refer to your boot sequence (make sure you
know what it is)
for 11.04 (or Linux mint 11) it looks like
menuentry 'Linux Mint 11, 2.6.38-8-generic (/dev/sda8)' --class
linuxmint --class gnu-linux --class gnu --class os {
recordfail
set gfxpayload=$linux_gfx_mode
insmod part_msdos
insmod ext2
set root='(/dev/sda,msdos8)'
search --no-floppy --fs-uuid --set=root a3180e09-4ce5-4955-8549-1c39acef8726
linux /boot/vmlinuz-2.6.38-8-generic
root=UUID=a3180e09-4ce5-4955-8549-1c39acef8726 ro quiet splash
vt.handoff=7
initrd /boot/initrd.img-2.6.38-8-generic
**
see the last line, this is what is important
here change
quiet to noquiet
splash to nosplash
and add the appropriate line depending on your graphics card (as done
to make the live boot happen)
* For ATI chipsets: radeon.modeset=0
* For nVidia chipsets: xforcevesa or nomodeset
* For GeForce and Generic: nouveau.modeset=0
* For Intel: i915.modeset=0
**
once thats done reboot and you should be up and running
