I'm using Ubuntu Server 11.10 x86, and after I make my normal selection (Ubuntu, with Linux 3.0.0-12-generic-pae) from the GRUB menu, the screen just goes blank - there's not even a cursor showing up.
Basically I (suspect that I) had a bad NFS mount tying up the boot process so I fixed that and now it seems like the boot is actually worse off. Here's the problem I had before: Is a bad NFS mount preventing a clean boot?
Not sure if this is useful, but when I hit the 'e' key in the GRUB menu, this is the configuration that shows up:
setparams 'Ubuntu, with Linux 3.0.0-12-generic-pae' recordfail set gfxpayload=$linux_gfx_mode insmod gzio insmod part_msdos insmod ext2 set root='(hd0, msdos2)' search --no-floppy --fs-uuid --set=root <long hex value> linux /vmlinuz-3.0.0-12-generic-pae root=UUID=<another long hex value> ro initrd /initrd.img-3.0.0-12-generic-pae
Recovery mode works just fine, networking and all. In fact, if select recovery mode it actually brings up the following menu:
Recover Menu (limited read-only menu) resume - Resume normal boot fsck - Check all file systems (will exit read-only mode) remount - Remount / read/write and mount all other file systems root - Drop to root shell prompt
and if I select
resume I get the following output:
<timestamp> tpm_tis 00:00: tpm_transmit: tpm_send: error 4294967234 initctl:Event failed Ubuntu 11.10 <server> tty1 <server> login:
Everything works fine after that.
Other things I've noticed: 1) when booting normally, the Num Lock and Scroll Lock lights on they keyboard show (after pressing the corresponding keys), but the Caps Lock doesn't 2) Ctrl+Alt+Fx to switch TTY's doesn't work 3) this link doesn't help at all: https://wiki.ubuntu.com/X/Troubleshooting/BlankScreen
So, back to the original question: why is my machine not showing anything when booting (in non-recovery mode)?
