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 http://forums.linuxmint.com/viewtopic.php?f=90&t=76449&p=445355&hilit=ati+on+mint+11#p445355 also see the following threads to learn more [1]“[all variants] Graphics Resolution- Upgrade /Blank Screen after reboot - Ubuntu Forums.” [Online].

[Accessed: 18-Jun-2011]. ** 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 @ Navdeep Singh This should help with you problem cheers -- Ram _________________________________________________________ http://www.munsiari.com -- ubuntu-in mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-in
