Thread: Framebuffer is not working with grub-efi-amd64 on Natty Narwhal
dear all,
struggling entire day getting framebuffer working on fresh installed system.
have intel dh67bl mainboard , intel pentium g620t cpu+igp.
when power on system can see messages:
i have tried few things in /etc/default/grub.code:error: no suitable mode found error: no suitable mode found booting however
here actual settings:
i have tested grub_cmdline_linux_default video=efifb:off , i915.modeset=1 , grub_gfxpayload_linux=keep , on, nothing worked me.code:grub_default=0 grub_hidden_timeout=0 grub_hidden_timeout_quiet=true grub_timeout=10 grub_distributor=`lsb_release -i -s 2> /dev/null || echo debian` grub_cmdline_linux_default="hpet=disable quiet reboot=a,w" grub_cmdline_linux="" grub_gfxmode=800x600 grub_gfxpayload_linux=800x600
after installation saw message, once:

hints?
my suggestion try different boot loader. in experience, grub 2 on uefi systems finicky , unreliable. imho, elilo more reliable. there ubuntu package, i'm using binary elilo project. don't recall offhand if ubuntu package installs directly efi system partition (normally mounted @ /boot/efi) or elsewhere. if latter, or if download non-ubuntu version, you'll need create subdirectory in /boot/efi/efi hold elilo installation. you'll need copy linux kernel (such /boot/vmlinuz-2.6.38-8-generic) , initial ram disk (such /boot/initrd.img-2.6.38-8-generic) whatever directory create elilo. you'll need create elilo configuration file. mine looks this:
this example boots specified kernel, using linux root (/) filesystem on /dev/sda4. "reboot=a,w" kernel option required on system or rebooting results in kernel panic. not computers suffer bug, significant number do, no matter boot loader used.code:prompt timeout=50 default=linux #chooser=textmenu image=vmlinuz-2.6.38-8-generic label=linux initrd=initrd.img-2.6.38-8-generic read-only root=/dev/sda4 append="reboot=a,w"
once you've set up, should able use board's firmware select new boot loader , set default; or if firmware limited on score, can use efibootmgr utility in ubuntu.
aware if you're dual-booting windows, elilo can't redirect boot process boot loader. thus, you'll have rely on either firmware's built-in boot manager or one, such refit. might not able use refit binaries site, though; seem unreliable except on macs. ubuntu includes refit package purely 64-bit version works on non-mac uefi systems, although graphics iffy. (you can uncomment line in configuration file enable text-mode display.)
