No joy here. Installed and rebooted, cannot even reach the grub screen. I'm attaching the Boot Info as most others have been doing, hoping for some help here.

I have a 10.10 live cd with me I'm using to access the drive and pull information. I tried a simple repair, but that didn't work. At one point I got to a repair mode, not quite sure how I got to that point. I tried repairing Grub and re-configuring it, but still the same symptoms. It may actually get past the grub screen because this is just single user, no real selections, I'm not 100% sure on that because I haven't had the time to take a good look, but hopefully someone can tell me where to look faster than me searching through every piece here.

Again, it gets to where usually I would expect the loading to begin, either a grub flash screen or something possibly beyond that, but I never see any text, images, anything indicating it's attempting to load.

============================= Boot Info Summary: ===============================

=> Grub2 (v1.99) is installed in the MBR of /dev/sda and looks at sector 1 of
the same hard drive for core.img. core.img is at this location and looks
for (,msdos1)/boot/grub on this drive.
=> Syslinux MBR (3.61-4.03) is installed in the MBR of /dev/sdb.

A little more info:

After following the tutorial in the stickies about 'Graphics Resolution- Upgrade /Blank Screen after reboot', I'm stuck at step two. I put the kernel image in 'text nosplash' and it sits at the loading screen saying:

'Loading, please wait...'

Interesting enough here...this is if I KEEP the 'vt.handoff=7' option...

*IF* I take the 'vt.handoff' option out of the boot command....it goes through as I expect and I get to a terminal successful boot.

Ok, been hacking away at this and ran into some results:

Acer Aspire 751h, I forgot I installed PSB drivers for video performance. Well, that seemed to balk my X11.

So, for future reference, the EASIEST way to do this seems to be to follow the instructions in the sticky for getting to the root shell




Note: Something that has changed with Natty and Grub... Look at the kernel boot line again, below:
Code:

linux /boot/vmlinuz-2.6.38-8-generic root=UUID=32939def-1f4a-4134-9b56-bed2319a9216 ro quiet splash vt.handoff=7

What we used to do to help display error meassages was to remove the options in blue ( quiet splash ) and type in " nosplash text " at the end of the boot line to boot into a text console (and have all the messages displayed).

Notice the new option in green above (" vt_handoff=7 "). Remove this boot option now also. This new option (from the wiki)
Quote:
For a smooth boot process, we want to display something other than a black screen as early as possible and leave it on screen until the desktop is ready. vt.handoff=7 is part of this. We have the boot loader display an aubergine background (we wanted to have an Ubuntu logo as well, but there are problems with different aspect ratios between the boot loader and the real system, so this is the next best thing). vt.handoff=7 then causes the kernel to maintain the current contents of video memory on virtual terminal 7, which is a new "transparent" VT type. The first time that the kernel is told to switch away from VT 7, either from Plymouth or manually (Alt-F1, etc.), these contents are lost and VT 7 reverts to text mode.

The upshot is that, when everything is working correctly, you get an aubergine background on the way out of the boot loader, then at some point Plymouth displays a logo and a progress indicator on top of that, and then the display manager comes up and smoothly replaces that with a login prompt.
So if we want to see all the error messages, we now also have to remove this from the boot line temporarily while trying to find problems.

So to boot into a text console to verify that the system is booting into Linux, we edit the above kernel boot line to look like this:
Code:

linux /boot/vmlinuz-2.6.38-8-generic root=UUID=32939def-1f4a-4134-9b56-bed2319a9216 ro nosplash text



Ok, now edit /etc/X11/xorg.conf and comment out the driver psb line.



#driver psb


That got me into the update. I'm going to WAIT to mark this as solved until I can find some more information on drivers to replace PSB in the meantime.
