Ubuntu 10.04 Spontaneous Re-boot

"Checking battery state... [OK]" => You have a graphic card driver problem!

When you boot, you should have a menu (else hold SHIFT key yo get it).
The second line should be: Linux with recovery.
In this mode, the graphic card is used with a restricted set of functionalities, and is more stable.
System->Preferences->Appearances, panel Visual Effects, choose None
System->Administration->Hardware Driver, if you can choose between free and proprietary driver, try which one is not installed.
And what is your Graphic Card ?

Hi Delance,

Didn't manage to successfully boot into recovery mode, only get a black screen by choosing the Low Graphics option.
Other graphic options don't seem to respond at all.

Have been able to boot normally though, Ubuntu has been up for about an hour now without crashing.
Have been trying to get as much info about the problem as possible, seems there are issues with my machine's graphics chipset:
Intel 82845G/GL Brookdale

Haven't been able to find anyone that has had success with Ubuntu and this Intel chip, and most of what is written in those threads are way above my head as I'm brand new to Ubuntu / Linux and have no technical experience with it.

Visual effects have been set to None from the start.
When going to Hardware Drivers, it simply states: No proprietary drivers are in use on this system.
(The list is empty, with nothing that can be enabled)

Please tell me there is something to be done about this with my limited knowledge, as I really don't want to return to Windows. I'm so not in the mood for Microsoft anymore...

A simple question here, does the machine boot and run ok with the live CD? i.e. insert the CD, choose "try without installing"?

Hi Bytesoup,

Had the same problem with the CD, in fact it wouldn't even load completely before it cut out.

But the computer has been running uninterrupted since yesterday morning.
I've made sure that all the power options are set NOT to turn off the monitor or put the computer to sleep.
I've set the screensaver NOT to come on, turned off all visualisation effects as suggested etc.

It seems to be OK now.
I hope it remains so.

I'Ve been having the same problem with Kubuntu i also had it with Ubuntu too so i just decided to switch to Kubuntu to see if it was the OS that was giving me the problem.. I'm working on what JAQ suggested on the last comment so heres hopeing it works

i have this same problem. it is quite annoying, in the middle of something it will randomly go to this screen. however mine does not reboot most times and instead it hangs and tries to reboot several times with no avail. I have only used linux for about a week now. so far ubuntu is great... except for this bug.

@shinn, to avoid confusion, please do your own fresh question from here

@marcobra, im not trying to cause confusin, im just looking for an answer to this sporadic bug. i think whatever will fix his will also fix mine.

@shinn but this is a marked as solved question so the user seems has solved it.

So putting info or question about your issue here has not a great effect and not help you to solve your problem.
i have seen your answer because i'm an answer contact (i see all the question and answer)

BTW thank you to help Ubuntu

Same problem here ... but doing all this did not fix it ...now I can't access screen saver without crashing

@marcobra you know this problem is really annoying? im not sure what u meant by your response but it sounded like you know how to fix it, yet u wont tell us. why?
i think maybe i should switch distros and perhaps i cant get one that doesnt have people as rude as you are

@shinn i don't know the answer so to have better chance to get a valid solution i suggest you to made a new question from here:

why you don't trust me?:

Marco is not rude. Simply when we ask list of pending question, we ask to Launchap "Open" and sometimes "Answered" and "Ask for information", but never "Solved" question. So only people who subscribed the question will see it. So please, open a new question. If you want, you can refer to old question in your post.
But "Solved" means "Dead and forgotten"

alright. i understand.
im still not 100% sure what mine says when it reboots but it is quite frustrating.
sorry for the misunderstanding
i apologize.
-sincerely,
shinn315
