Raffaele Candeliere, thank you for reporting this and helping make
Ubuntu better. Does this issue still occur if you do a new install of
Vivid via http://releases.ubuntu.com/vivid/ubuntu-15.04-desktop-
amd64.iso ?

Title:
X fails to automatically detect ATI radeon RV600 card
Status in xorg package in Ubuntu:
Incomplete
Bug description:
Good day.
I'm testing pure EFI boot capability on my iMac 7.1 (graphic card ATI radeon
HD2600 pro).
So far, with Ubuntu 14.10, i've been able to boot directly into a perfectly
working system using the EFI kernel stub.
No GRUB, no ELILO, no rEFIND, no boot manager whatsoever! And the result was
amazing!
Boot up time reduced to a fraction of the time needed by GRUB, for example,
Compiz compositing much more quick, smooth and and efficient. I could notice
even some graphical detail (e.g. Text shadows in the GDM log-in screen) that
were not present if booting via GRUB.
The way to accomplished this is simple:
1) Create a small (40MB or less) HFS+ partition. E.g. #> sudo mkfs.hfsplus
/dev/sdaX -v "Ubuntu (EFI-Stub)"
2) Copy to the new partition the files vmlinuz-3.XX.YY-ZZ-generic.efi.signed
and initrd.img-3.XX.YY-ZZ-generig. Also rename them to "vmlinuz.efi" and
"initrd.img" for sake of simplicity in further command line work. Furthermore,
Apple's EFI won't boot anything that doesn't end with the ".efi" extension.
3) Create a boot entry in the NVRAM using efibootmgr like this: #> sudo
efibootmgr -d /dev/sdX -p Y -c -L "Ubuntu 14.04 LTS" -l /vmlinuz.efi -u
"root=UUID=b0c4efb9-95b0-4e5d-98e1-8beb43f413c2 ro rootflags=subvol=@ quiet
splash initrd=\initrd.img"
4) reboot (and enjoy!)
As i've said, in Ubuntu 14 all this is working fine, but after the upgrade to
Ubuntu 15, "X" doesn't start anymore. The system starts up correctly but X
fails (with error: (EE) No devices detected. (EE) Fatal server error: (EE) no
screens found) dropping me to a tty console login.
I'm not shure if it is a X problem or a kernel KMS bug, but i'm more inclined
to think of a problem with X because i've tried to boot Ubuntu 15.0 with the
old kernel (3.13/16) and the problem is still there.
I've also tried to add "vt.handoff=7" to the command line args for the
kernel, like grub does, but the result is even worse. The system freezes
completely at the moment of starting X.
Please note also that booting via grub is working. X starts, much more slowly
but starts. (Actually i'm reporting this bug from the very same system booted
using GRUB. I have a second HFS+ partition where i installed grub and i can
access it by holding down the ALT key at power-up)
Thanks for your work. I really hope that booting directly via EFI stubs will
grow mature because the performance increase is really big.
Thanks again.
