I was able to get UEFI working with kernel 3.11.0-12-generic on my XPS 13 L322x HD
I booted into my XPS bios setup, navigated to the boot tab, and configure the setting as below; Secure Boot: Disable Load Legacy Option Rom: Enabled Boot List Option: UEFI As stated in my previous comment (#12) I had the backlight and screen refresh issues. Now I can see my desktop and adjust my brightness. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1234546 Title: Plymouth screen refresh is bad when Live USB is started in UEFI mode To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1234546/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
