Upg from 11.04 to 11.10 - LightDM fails to load

[CaptSaltyJack]

Count me among the many who now have an unusable system due to the in-place upgrade (I should've known better and done a clean reinstall).

My System76 laptop won't boot up properly. LightDM fails because the NVidia stuff is completely hosed. I can't see details why, but Xorg and lightdm logs just say the nv module failed to load. Might be something with the new Linux 3.0 kernel? I'm not sure. All I know is, I've gotta get stuff done and this really put a damper on things.

Any help would be appreciated.

alt+ctrl+f1 ..... will get to a terminal screen log on as normal and then ......

Try to install nvidia-current

sudo apt-get install aptitude
sudo aptitude install nvidia-settings

sudo aptitude install nvidia-current

watch what it says on screen as it installs ..... look for any fail ....hopefully it will be ok and load the modules as required

[CaptSaltyJack]

Those nvidia packages are already installed.

When you boot up can you still select to drop into the previous kernel

I have heard others say that this works for them ......

I'm having a similar issue:

I sort have caused it.

After seeing that lightdm loaded fine I did

apt-get purge gdm

and for whatever reason lightdm won't load anymore

[23dornot23d]

to put gdm back

sudo apt-get install aptitude
sudo aptitude update
sudo aptitude install gdm

if you want lightdm

sudo aptitude install lightdm


choose the preferred DM when it asks you .......

I sometimes install kdm ( which works for me but pulls a lot of other packages in too )

Got it! The correct solution is:

- upon boot, ctrl+alt+F6 (or F5, F4) to get into a terminal
- log in
- "sudo dpkg-reconfigure lightdm"
- choose gdm as your greeter, go back to shell
- "sudo start gdm"

That should log you in.

And then I opened a gnome terminal and did:

- "sudo dpkg install --reinstall lightdm"
- "sudo dpkg reconfigure lightdm"
- choose lightdm as your greeter
- reboot

This seems to have worked for me.

Nice work - mark it as solved and I will add that in my list so others can see this solution

Thank you

Hi CaptSaltyJack, some questions:
the command "sudo dpkg install --reinstall lightdm" don't worḱ for so I tried "sudo apt-get install --reinstall lightdm", is that ok ?

the command "sudo dpkg reconfigure lightdm" didn’t work either so I tried "sudo dpkg-reconfigure lightdm", is that ok ? becouse I got a response wierd response after choosing the greeter lightdm --> "dpkg-maintscript-helper: warning: environment variable DPKG_MAINTSCRIPT_NAME missing
dpkg-maintscript-helper: warning: environment variable DPKG_MAINTSCRIPT_PACKAGE missing". please help!

Sorry, I meant sudo dpkg-reconfigure lightdm.

Actually I'm not sure this entirely fixes the problem, as this morning I had booting issues.
