Freeze after start up (video drivers)

[cdoublejj]

So I have been getting freezing after start up just after it gets to the desktop (consistently, same time every time) so i did some trial and error and found that installing with out internet worked, as in no freezes.

So i decided to try adding things one by one till it started locking up again and the first thing i tried was video drivers and low and behold it locks up just after boot like before.

I installed the Nvidia {recommended} drivers, so i'm wonder if there isn't a way to disable them before/during boot So i can try [post release drivers]?

Is there a way to see what video drives it is installing, like what card it thinks it is detecting?

Specs:
Asus A8n32-SLI Deluxe
4gb DDR 400
200GB WD IDE
BFG GTS250 1GB Vram

Back Story: i've been running Lubuntu in VMplayer for while with far less resources and it has been just awesome so now i finally found a spare hard drive and want to install and run it on real hardware. 8)

EDIT: By freezing i mean total lock up, i believe it's a hard lock but, be sure because it's a KVM switch and the old num lock trick doesn't work.

Managed to disable the drivers and switch to the "post release update" driver and it still locks up after boot.

[cdoublejj]

the first time i was able to switch drivers i must have stumbled onto an invisible boot menu by pressing escape because text showed before the Lubuntu menu.

This time i frantically tapped escape and tired the arrow keys and enter to no avail, i just barley managed to disable the driver but, it locked up halfway through (locking up at ti's normal time a minute or so after booting up) and it still persists to freeze as i think it didn't totaly manage to disable the driver.

I'm at a loss here.

so i did this...

[quote name="tom.slick" url="/t/1312334/lubuntu-freezing-after-auto-log-in-nvidia-drivers#post_18284419"]Press and hold the "shif"t key after bios to bring up your grub menu
Select the default entry (it should already be highlighted)
And press "e"
A new menu will appear. look for a line that starts

linux /boot/vmlinux

At the end of the line you will see something like

quiet splast $vt_handoff

Chang quiet splash to text and add the letter "s" to the end
So that it looks more like

text $vt_handoff s

Then press "F10" to boot
This will bring you to a command line
Then at the prompt type

sudo apt-get purge nvidia*

answer prompts, then

sudo dpkg-reconfigure xserver-xorg

answer prompts, and Nvidia should be gone[/quote]

i think it worked how ever it still locks up, is there a way to find out what is causing it to lock up?

[cdoublejj]

Well, i think i'm gonna try reinstalling with out internet again to confirm it is the drivers.

[cdoublejj]

So, i re clean installed double, triple, quadruple confirmed it is the driver. I found this,

http://askubuntu.com/questions/15438...vers-activated

However it does not fix this issue, then i found this,

http://forums.fedoraforum.org/showthread.php?t=279781

this guy found out with the drivers his GPU was falling off the bus. I'm not sure whats happening in my case but, unlike that guy I'm getting hard locks.

Looks like you are having more than your share of troubles:

see if this works for you:
Boot to command line video issues:
Remove nvidia drivers -> install nouveau -> reboot and let Ubuntu detect your videocard when you're running the desktop -> install the new drivers -> reboot.
#Remove nvidia

sudo apt-get update
sudo apt-get purge nvidia-*
sudo apt-get install nvidia-current

sudo apt-get purge nvidia-common
#Install nouveau and remove the xorg.conf
sudo apt-get install xserver-xorg-video-nouveau
sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.backup

Thanks for the reply. Basically those are instructions for going back to default drivers no?

I can just as easily clean install. The thing is i have tried 3 or 4 different driver version already, it detects the correct video card.

However the above instructions might make since if wanted to keep the install for reading logs, which i know nothing about.

I'm at the point now where i can bet money and make promises that any driver version i install is gonna cause a lock up after boot/log in.

I could understand if it was/is hardware problem but, it runs and games just fine in windows 7. (totally different hard drive no dual boot)

I'm gonna go ahead and run those commands from recovery mode.

[cdoublejj]

Just ran the commands how ever some of it didn't work take, perhaps those commands are tailoyerd for Ubuntu instead of Lubuntu.

for now i'm gonna leave in the root command shell aka recovery mode till i have more time.

Regret not helping much, know how time-consuming trouble shooting can be !

To see your graphics card and info:

sudo lshw -C display
lspci | grep VGA

and suggest comparing to the compatibility list :
http://www.ubuntu.com/certification/catalog/

and then there is the official "guide" info irt Nvidia:

Install Latest Nvidia/ATI drivers

Ubuntu uses a GUI frontend to Jockey for the installation of the proprietary nVidia drivers (and other proprietary drivers).
Menu -> System -> Hardware Drivers

• Sometimes after a kernel upgrade a proprietary driver may stop working. In such a case, try installing the new linux-headers that match the newly upgraded kernel:

sudo apt-get install linux-headers-$(uname -r) If dkms and build-essential have never been installed on your system, these can also be worthwhile: sudo apt-get install dkms build-essential
