Here the grub.cfg and the /etc/default/grub file.

Please attach your noth grub.cfg (you confuse concept so I'm not sure what you really mean) and don't use debug=all on EFI, it doesn't work due to EFI memory management.

Oh, yes, File #27881 is on "console", #27879 is on "auto". The corrupted screen on #27880 is visible on the top of screen.

It hangs after the choice of entry. The last think i see is the line "Loading Linux Kernel..." then it hangs.

I've put some debug info, and the corrupted screen on attachments. Also the videoinfo on "auto" and "console".

I'll try adding resolution explicitly and see if that changes the whole thing.

At which stage does it hang? Before or after the choice of entry? What's the last thing that you see? There is no GRUB_GFXMODE=text, you just make mode selection fail and it's equivalent to setting GRUB_TERMINAL_OUTPUT=console. Can you attach a picture of this corruption and the output of "videoinfo" when booted in text mode? Did you try setting resolution explicitly?

I have a problem when booting on GRUB while using GRUB_GFXMODE=auto on BZR Revision 4820. I have a Inspiron 14z, with hybrid graphics (ATI / Intel, Muxless system), bios revision A10, booting with UEFI.

If I set the mode to auto, it just hangs up and a small screen corruption is seen on the screen. If i put GRUB_GFXMODE=text on /etc/default/grub and then regenerate the /boot/grub/grub.cfg, the system works correctly.

More specs:

OS: Arch Linux x86_64
GRUB: grub-efi-x86_64-bzr [Rev. 4820]
Linux Kernel: 3.8.6-1-ARCH

Output of lspci and dmesg | efi on files.
