Is there a Ubuntu safemode?

[SNYP40A1]

My Ubuntu 9.1 installation crashes either during bootup or after about 10-20 seconds after bootup. Is there a way to run Ubuntu with the minimal settings -- similar to Windows XP safemode? It handles the recovery console fine and never crashes in Windows XP. I ran memcheck and it's not the hardware. Using Intel 945 graphics chipset. Or is there any information that I can provide to help diagnose this problem? Ubuntu 9.1 runs fine on one of my other systems.

in the login screen, just before i have to enter my password, at the bottom i can choose between several session types, including gnome, kde and gnome safe mode.

Hi,

I'd suggest booting and running from the LiveCD and see if that is stable as a starting point.

Phill.

You can launch ubuntu in command line mode if that's any help, at the grub screen press e to edit the line for ubuntu, then edit the line with the kernel information(it litterally starts kernel), and put at the end:

nosplash 3
This will turn off the splash screen and boot into command line more(init level 3 instead of 5 for full graphics).
Press enter, then b to boot this modified line, you should now be able to see the problem.

Can you tell me where to insert the nosplash 3 command? I have this:



recordfail=1
if [ -n ${have_grubenv} ]; then save_env recordfail; fi
set quiet=1
insmod ext2
set root=(hd0,6)
search --no-floppy --fs-uuid --set 945658e3-4807-4e75-aa06-bbdd4d52b\
0d5
linux /boot/vmlinuz-2.6.31-16-generic root=UUID=945658e4-...
...0d5 ro quiet splash
initrd /boot/initrd.img-2.6.31-16-generic


I changed the splash to nosplash 3 as well as put nosplash 3 after the splash commend. However, I still see the ubuntu startup screen and it looks like it's loading full graphics. How should I modify the above to use minimal driver set.

Not completely sure yet, but the problem might be related to the BIOS. I have a MSI G945 and Core2Duo. Others have had problems with that combo. Appears to be a BIOS update available...I'll try it.

Took a bios update, but didn't seem to fix :-(
