Stuck at "checking battery state..." in ubuntu 12.04. Please help.

[agentfortyseven]

Hi,
nouveau (open source driver for nvidia) is pre-installed. Have you tried it ?

You can execute the commands below to make sure that no nvidia-proprietary driver left in your system and nouveau will be used.

sudo apt-get purge nvidia-*
sudo rm /etc/X11/xorg.conf # if the file does not exist , then is OK 
sudo apt-get install nvidia-common ubuntu-desktop
sudo apt-get install --reinstall xserver-xorg-video-nouveau
sudo dpkg-reconfigure xserver-xorg

and at the end , give this command to reboot your pc

sudo reboot

If everything work ok , then is not needed to install additional-proprietary nvidia driver.

Thanks

I tried this and I was finally able to login from the GUI.
But there is a small problem with this procedure.
Whenever I reboot or start my computer, after the purple screen with red dots I see "a purple screen with a dark patch" for about 10-15 seconds followed by a white screen for some 5 seconds and then I see the login window.
Can someone please tell me what could be wrong?

i get that same checking battery state message on my headless server. it's because I uninstalled a desktop manager. I am guessing lightdm was uninstalled when you uninstalled that gnome thingy. try to reinstall lightdm.

also, what happens if at the checking battery state screen, you hit ctrl-alt-f1, login textually. then at the prompt enter this
sudo service start lightdm

Now that I can finally login, I can see that I have lightdm installed on my computer.
Do I need to run the following command from the terminal?

sudo service start lightdm

Hi ,
lightdm is already started . You don't need to start something manually. The problem probably is with graphics driver , Nvidia additional drivers.
Now that you have purged completely nvidia , you can try to install another version if you want.
You have 2 options.
One is nvidia-experimental-304 and the other is nvidia-experimental-310

First try

sudo apt-get install nvidia-experimental-304 nvidia-settings-experimental-304
sudo nvidia-xconfig

Reboot to see if you can login without problems.

The other "problem" with plymouth(during OS start, that with the dots ...etc) , I cannot handle it . Sometimes work good , sometimes not.

If the experimental-304 not working for you , try the 310, but first remove manually the 304.

sudo apt-get remove --purge nvidia-experimental-*
sudo rm /etc/X11/xorg.conf

and then try 310

sudo apt-get install nvidia-experimental-310 nvidia-settings-experimental-310
sudo nvidia-xconfig

and reboot again.

Thanks (hope you solve it soon)

Thanks a lot. Now I don’t see that ugly screen at login however now I see an NVIDIA splash screen at startup for a couple of seconds and I can still see that bright white screen I talked about in my earlier post.
Should I try nvidia-experimental-310? Will it fix my problem? Or is there any other way?

Yes ? is it beautiful ? never saw it

Well, nobody can tell you if will work better or worst. Experimental is experimental.
If you want to give it a shot.. you know how to remove if not work.

Thanks

First try
Code:
sudo apt-get install nvidia-experimental-304 nvidia-settings-experimental-304
sudo nvidia-xconfig

I actually forgot to run the second command and restarted. Now when I ran the second command I don’t see the white screen anymore but I do see the nvidia splash screen. And the boot time has increased compared to what it used to be. I'm gonna mark this thread as solved anyway.

Yes ? is it beautiful ? never saw it

Nah its not beautiful at all but I can deal with it. I would however be glad if you or someone else could help me stop it from appearing at login.
And thanks a lot for your help NikTh and others too.

The only thing I can suggest is this command

sudo update-alternatives --config default.plymouth

and if the results are more than one , choose the Ubuntu's plymouth screen.

Then run

sudo update-initramfs -u -k all

Thanks

you can add

Option "NoLogo" "True"

to your xorg.conf file I am just not exactly sure which section it suppose to be put in.

[agentfortyseven]

The only thing I can suggest is this command

sudo update-alternatives --config default.plymouth

When i ran the above command I got the following message:
There is only one alternative in link group default.plymouth: /lib/plymouth/themes/ubuntu-logo/ubuntu-logo.plymouth
Nothing to configure.

Its alright I'm happy with my computer right now.
I do however have one final question:
Is nvidia experimental 304 driver more stable or experimental 310? Because I have experimental 304 driver and sometimes my computer freezes.

I don't have any xorg.conf file on my computer my friend. But thanks a lot for your help.
