nvidia drivers

[adrianm]

when i installed kubuntu one of the first things i did was check for and update drivers, as part of this it got the latest nvidia drivers.

On rebooting kde fails to load, i have a feeling this is due to those drivers.

From the command line how do i uninstall those drivers? or failing that is there a way to reset all of kde back to what it was just after install without re-installing it? Some kind of epic reset?

(1) What, exactly, do you see when you boot the computer?

(2) In the file /var/log/Xorg.0.log there should be some lines that include an (EE) indicating an error. What are those lines?

Re: nvidia drivers

it freezes on the login page (cursor blinks but cant type or move mouse pointer)

Just before the splash screen there is a moment where a light blue screen with an error message appears but it does stay long enough to read it (tried several times) The most i could get was something about MCU request failed or some such and mentions hardware.

ill have a reboot and look at the file

Re: nvidia drivers

If you can boot into recovery mode, or else at the screen where it hangs you can probably Ctrl-Alt-F1 and get a normal console, log in (as your normal user) and do

sudo service kdm stop

sudo apt-get update

sudo apt-get install linux-headers-`uname -r`

Then you can shutdown and try a reboot. I'm not sure if jockey-kde will automatically finish compiling the proprietary driver or not -- we can work on that once we see how the reboot goes.

Re: nvidia drivers

ctrl-alt-f1 did nothing - i used the recovery console.

the update went fine but when i did the other command it just said "unable to locate package"

Hmmmm. That is not expected.

OK, let's review the bidding. You are running Kubuntu 11.04, right? If you can pop open a terminal, I would like to see the output of these two commands:

uname -a

sudo apt-cache policy linux-headers-`uname -r`

Note that the little marks enclosing "uname -r" are not apostrophes, they are (on a U.S. keyboard) the lower-case character below the tilde "~".

Re: nvidia drivers

aa that might be the problem :P hang on

Re: nvidia drivers

OK, good. I would first try to get the nvidia driver running correctly, if possible -- if it turns out not to be possible then probably you can get back to the nouveau driver.

so, at your recovery console

sudo service kdm stop

sudo apt-get update

sudo apt-get install build-essential

sudo apt-get install --reinstall nvidia-current nvidia-common nvidia-settings

sudo nvidia-xconfig

sudo service kdm start

What do you see?

[adrianm]

Re: nvidia drivers

all commands ran ok, the xconfig backed up the config file and then wrote something new to it, started kdm and froze as normal

Re: nvidia drivers

Which model of Nvidia GPU do you have?

[adrianm]

Re: nvidia drivers

geforce gtx 260

Re: nvidia drivers

Wow. I have the same card, and it works with the "Additional Drivers" just fine. I dunno what the problem could be.

Can you take a look at the log file at /var/log/Xorg.0.log and see if there are any lines that contain an (EE) message? If so, post them please.

[adrianm]

Re: nvidia drivers

hmm maybe its not freezing after all -

the only EE error i could find was

[10.043] markers: (--) probed, (**) from config file, (==) default setting, (++) from cmd line, (!!) notice, (II) informational, (WW) warning, (EE) error, (NI) not implimented, (??) unknown.


but right down the bottom i saw for each of these;

power button
HDA headphone (i dont have any headphons)
AT translated set 2 keyboard

a line that said (/dev/input/event0) no input drive/identifier specified (ignoring)

so the graphics are fine ti just cant detect my peripherals all of a sudden?
