Ignore the first post, sorry :)

But I'm surprised. By reading fast, it seems it affects Intel graphic card, and not NVidia.

Thanks to both of you. Before I make any changes I want to be sure. I did change my file system this time when I reformatted and upgraded from ext3 to ext4. So that could be the problem, right? There seems to be two ways to solve this problem from the links you gave:

PLAN A:

Information from.... https://ext4.wiki.kernel.org/index.php/Ext4_Howto#Converting_an_ext3_filesystem_to_ext4 it's telling me to do this....

To enable the ext4 features on an existing ext3 filesystem, use the command:

# tune2fs -O extents,uninit_bg,dir_index /dev/DEV

if that seems good to you I'll try it...I figure that is a terminal command, right? And then I'm to do this:

After running this command (specifically, after setting the uninit_bg parameter), you MUST run fsck to fix up some on-disk structures that tune2fs has modified:

# e2fsck -fDC0 /dev/DEV

However all these notes sounds scary:

Notes:

    * Running fsck will complain about "One or more block group descriptor checksums are invalid" - this is expected and one of the reasons why tune2fs requests to fsck.
    * by enabling the extents feature new files will be created in extents format, but this will not convert existing files to use extents. Non-extent files can be transparently read and written by Ext4.
    * If you convert your root filesystem ("/") to ext4, and you use the GRUB boot loader, you will need to install a version of GRUB which understands ext4. Your system may boot OK the first time, but when your kernel is upgraded, it will become unbootable (press Alt+F+F to check the filesystem).
    * If you do the conversion for the root fs on a live system you'll have to reboot for fsck to run safely. You might also need to add rootfstype=ext4 to the kernel's command line so the partition is not mounted as ext3.
    * WARNING: It is NOT recommended to resize the inodes using resize2fs with e2fsprogs 1.41.0 or later, as this is known to corrupt some filesystems.
    * If you omit "uninit_bg" on the tunefs command, you can skip the fsck step.

PLAN B:

Seems less scary...the link is... http://georgia.ubuntuforums.org/showpost.php?p=9226987&postcount=9 the instructions are:

To boot, remember to press/release SHIFT (maybe multiple times helps) AS SOON AS Ubuntu starts booting: that is just before the Ubuntu logo appears.
By doing this, you are asking the boot-loader, Grub, to show you a menu with various boot options.
Choose to boot with the kernel with the the second-highest version number

After having booted up, open a Terminal and type:

Code:

echo options i915 modeset=1 | sudo tee /etc/modprobe.d/i915-kms.conf
sudo update-initramfs -u

Then reboot normally.

Take plan B. Plan doesn't seem related to your problem.

It doesn't work. When I tried loading the next kernel down on the list, (there were only 2) it doesn't boot. And I get a new error message the NVIDIA graphic drivers are wrong....or something to that effect...sorry I didn't note down the exact error phrase. Man, I hope I'm not going to have trouble with NVIDIA again ..... I spent many hours on this problem before in 9.10, and I finally went back to 9.04. So I'm stuck...I don't know what to do...the way I get back into the normal mode is I run the recovery mode, and there is an option to update the grub bootloader...it doesn't really seem to do anything ....but usually I can boot back to ubuntu with the top kernel...

Perhaps I should go back to a more stable version of ubuntu...I don't remember having some many trouble with 8.10....I just want a computer that I can do my work on....please help.

Try booting to recovery root console and run:

nvidia-xconfig

Then reboot, should be ok. If it still doesn't boot, boot to recovery root again and run:

nanao /etc/X11/xorg.conf

and change the driver line

from:

Drive "nvidia"

to:

Driver "nv"

Then press CTRL+X
Press Y
Press ENTER

then reboot

Ok...but I only had the problem of Nvidia error when I tried booting to lower version kernel number...so you think I should do this anyway? recovery root console is the black and white screen?

it seems this thing is melting down....I got a new error, but the screen flashed so quickly I couldn't read it. Again what is the recovery root console...and do I apply the changing the driver line to the first kernel or second? I can get in to the main ubuntu window at least for now so I can give you any terminal read out ... I think there must be some crash reports logged in...and as I just load this 10.04 it would seem there can't be to many reports to look through...but I'm just guessing and need some help...I leave for a transatlantic flight in 3 weeks and really need this baby up and running to prepare my work...so I putting out an urgent appeal. Thanks for the help so far...I really appreciate it.

it's the same today...if I tried to boot directly into Ubuntu I get the black and white screen...so then I reboot to the recovery mode and run the program to reload the grub bootloader...then I reboot and I'm in Ubuntu. I can't do Plan B as it tell me I have nvidia errors if I chose the lower kernel to try and boot into. I tried dong Actionparsnip last suggestion but as nothing happen I don't think I did it right. Any ideas?

I don't have any data to lose yet...so should I go back to a more stable or compatible version of Ubuntu for my acer?

just keeping a running log here...this morning when I booted up there was no problem...so in other words it comes and goes, but mostly comes

Captains log...star-date..May 19....today firefox froze...it seems the problems I have had for the past 7 months (note my other logs on launchpad) with other version of ubuntu are reappearing. Also office crashed twice in a space of five minutes...even to type this is a pain in the butt...it looks like it's time to jump ship and reboot to the 'other' OS. I think my acer just doesnt work with ubuntu....after trying it now for a year I think it's time to jump ship. Maybe when I get back from the States in a few months I'll try another version of Linux if any of you have a suggestion on a really stable version that works wonderfully with my graphic card GeForce 6100 nForce 405 please let me know. I don't do gaming so it isn't a demand for me....i just need a stable system for all kinds office work, lots of online work, and watching documentaries. If someone could answer this question I can close up this thread.

I suggest you check your ram for issues from the grub menu.

I have no idea how to do that please inform me

if that means running a memory test...I have done that recently...in fact a very extensive of 10 hours test...later I found the hard drive had errors...so computer went to the shop replaced the hard drive all the rest of hardware is good they tell me

So this is what is happening....every 5 or 6 boots...the system hangs up....that is goes to the black and white screen with text...still don't know what to call that as I mentioned before...so then I do crt, alt, delete, and when the options come up for booting (as I have a dual system) I then chose the recovery mode...from there I choose update bootloader...then resume normal boot...which it doesn't....but after another ctr, alt, delete it reboots normally.

Other than that office and powerpoint are crashing regularly....which of course is a real bummer for office work...last time office crashed I wasn't on-line and had no other programs opened.

I hope I can get some response and help on this...I live in the middle of boonies, and there is no one around who know Ubuntu. If this problem is not solvable let me know...so I can make other plans. I did ask before if perhaps another version of Lunix would be more suitable for my needs...but I guess these kind of questions don't get answer here?

Perhaps you could install "GNOME Sensors Applet 2.2.3" package "sensors-applet" and check temperature of PC.
Sometimes bugs appears at spring, simply because weather get warmer!
I already experienced it.
Can you post a photo of this "black and white screen with text" at <email address hidden> ?

Thanks Delance....I'll try the sensors...I noticed something unusually while in Ubuntu the computer is now constantly processing data...you know all those little clicking sounds....however today while using Windows, (because my Open office is crashing all the time)...the computer was silent.

How would I post a photo of the screen...that is how can I take a screen shot of it...with like a digital camera?

Yes, I tried with my digital camera and it is readable.
All the little clicks you talk could be accesses to hard disk, which should not be.
Else your hard disk is dying (but it would make same noise with Windows)
Else an application uses the disk continually.
In upper bar, with contextual menu "Add to dashboard"->"System Monitor" and select hard disk.

this is a new hard disk...hope isn't faulty
ok...I'll do the picture tomorrow...shutting down for the night.
could you relay the terminal commands for installing that sensor?
I tried Ubuntu Software Center and installed a program but can't find it, then I went to Synaptic manger ...it said it was installed but ...couldn't find it

I went to the System Monitor....it seems that ubuntuone-syncdaemon is chewing up my CPU. Even with killing it still seems the CPU % use is quite high...anyway once I killed the ubuntuone...the clicking stopped. I didn't find any where to select hard disk under System Monitor

UbuntuOne.

I have just read an paper on UbuntuOne. It can synchronize a remote disk with your local disk, and it seems it is what happen.
As network upload is slow, it regularly read a disk block to send it to remote location.
Unfortunately, I don't use UbuntuOne, and so can't help you.
Best should be to post a question like "UbuntuOne - sync configuration" to request help.

Installing sensor monitor.

At top of your screen, you have a bar. Right-click on middle of it. You should see a menu with entry "Add to Panel".
After in the new list you should have something link "Monitor sensor"

Thanks Delance for your help...I'm going to close this thread...I'm leaving for the USA for 2 months and Ubuntu is on my desktop which of course I won't be bringing. I think when I get back from the States I'm going to try one of the other Linux OS...Ubuntu has been one headache after another for sometime now and office crashing regularly is the final nail in the coffin.

Mint seems to be more reliable. But as Mint is based on Ubuntu and released few months after Ubuntu, perhaps it's based on a "fixed" Ubuntu!
The Debian distribution is known to be less modern but highly reliable.

The other big family is Fedora and Mandriva, which uses RPM packet.

Thanks...I'll try MInt
