    Re: Dell XPS 13 Haswell built-in display problem with Ubuntu 13.10

    When you installed in legacy mode, did you put the boot loader on a separate partition or with the windows one?
    Cant find the post(s) anymore where this procedure is describe and how to convert the installation to an efi afterwards.

    Im not sure how much problems this will cause when it is time to upgrade to 14.04, which seems to not have the screen problem. Maybe it is just better to wait.

    With a BIOS boot and MBR, you install the grub boot loader to the MBR of the hard drive as we have done for over 30 years. Both Windows on Ubuntu only boot from MBR(msdso) partitioned drives with BIOS.

    If using UEFI you have to have the newer gpt partitioning and both Ubuntu and Windows only boot with UEFI.

    Only Ubuntu will install to gpt partitioned drives and boot in either BIOS or UEFI. With BIOS you have to have a 1 or 2 MB unformatted partition with the bios_grub flag. With UEFI the first partition should be the efi partition which is FAT32 formatted and has the boot flag. Boot-Repair then can convert Ubuntu from UEFI to BIOS or vice-versa if correct partitions and gpt formatted. But Windows does not easily convert.

    Thanks! However, after testing 14.04 that works excellent (no display issues in uefi mode and many other things that works much better), it seems like a better option to go with that version. Only 2 weeks until the beta release.

    Just understand there may be breakage.
    But they are a bit better now about not updating one part that depends on another and not doing the other so it breaks.

    Re: Dell XPS 13 Haswell built-in display problem with Ubuntu 13.10

    Hello,

    I re-installed Windows 8.1 with factory settings and then installed Ubuntu in dual-boot in legacy mode.

    I was not able to launch Ubuntu in UEFI mode so I used boot-repair. After replacing the GRUB files at the good location I have now a "grub rescue" issue and I'm not able to boot Ubuntu anymore (Windows still works).


    Thank you for helping

    Since this is a dual boot with Win8 with uefi and what not I am not sure if this would work (it would if you have a pure Linux system whether single or multiboot)

    boot from a live usb. Find out where is Ububtu's root (/) partition or just where Ubuntu is if you have no separate root.

    Code:
    blkid
    (or sudo blkid if the command doesn't show anything)

    Mount the partition where your Ubuntu / is (or where Ubuntu is if you have no separate / partition), let's say it is in sda5
    Code:
    sudo mount /dev/sda5 /mnt
    sudo grub-install --root-directory=/mnt /dev/sda
    Then reboot.

    Notice the first command involves the partition (/dev/sda5 here) while the second involves the whole drive (/dev/sda here)

    Edited: life would be a lot simpler if you get rid of Windows.

    Thanks ! But when I try this it writes "mkdir: cannot create directory 'mnt/boot/grub/i386-pc' : Read-only file system"

    After Boot-Repair converted to UEFI, are you still trying to boot in BIOS mode? You may have grub boot loader in the protective MBR, but will not work if now UEFI.

    Post the link to the Create BootInfo report. Is part of Boot-Repair:

    If I try in UEFI mode, I enter Windows without the possibility to choose Ubuntu.

    If I try in legacy mode, I have a "grub rescue" issue and I can't load Ubuntu.

    Here is the URL of the Create Boot-Info report : http://paste.ubuntu.com/6965320/


    Thank you very much !

    Your Ubuntu install has been converted to UEFI so the grub in the MBR will not work in BIOS boot mode.
    But in UEFI you should have a choice to boot the ubuntu entry.

    You do not have the secure boot version installed, so you must have secure boot off to see the ubuntu entry in uEFI as with secure boot on, only secure boot systems are shown.

    Discussion of Haswell & Intel with Dell:
    Ubuntu on the Precision M3800 or XPS15 Nov 2013
    http://en.community.dell.com/techcen...ion-m3800.aspx
    Running in legacy BIOS mode or in UEFI mode both work, but for now you'll need to enable "Legacy Option ROM" in the BIOS if you're running in UEFI mode because of the display's backlight. This is because of an issue with the Intel i915 driver that currently affects several systems from many vendors. If you don't enable this BIOS option, the backlight will be stuck at the lowest setting in Linux.
