Nvidia Drivers

[Vaxon]

I have recently done a fresh kubuntu 12.04 installation
And everything works great except that neither of the Nvidia drivers in the "Additional Drivers" work
When I install either of them and restart my system moves extremely sluggish until I uninstall them

Is there a solution for this?

Additional info:
I'm running Kubuntu 12.04 64-bit
Graphics Card: Geforce 6150SE nforce 430

1) Fresh load Kubuntu 12.04 with horrifying draw delays
2) Reboot, then log in to KDM screen using failsafe KDE settings
3) Went to proprietary hardware manager and updated to "updates" driver
4) Tried logging out and in... things were worse
5) Rebooted again, and logged in with failsafe KDE (BTW - I had to press a key to continue booting... screen was black, so I didn't know it was waiting)
6) Added the repo above and intstalled that version of current (295.33)
7) Rebooted and logged in to failsafe KDE
8 ) Went to proprietary hardware manager and re-selected "current driver".
9) Logged out.
10) Logged in normally and all was good.

This fixed the issue

You could try from a terminal or konsole:

sudo apt-get update
sudo apt-get install nvidia-current-updates

nvidia-current is already the newest version.

don't think thats it

There is a bug in the current nvidia driver with certain nvidia cards. Nvidia is working on it and recommends that you either install a previous version or wait until the next version. You can also use the nouveau driver or if you want the nvidia driver, tell kde to use xrender instead of opengl.

The other thing you might try is turning off compositing and see if that gives you any improvement.

System Settings > Desktop Effects > General

and uncheck the "Enable Desktop Effects at Startup" box. See if that give you any improvement; if it does, then the
NVIDIA driver bug is likely the culprit.

Alright, thanks for the info its greatly appreciated
Guess I'll just wait this one out until the bugs are worked out

I have some serious issues with nVidia driver on a freshly installed Precise Pangolin too. I guess we will have to wait for an update.

The newest nvidia drivers have some issues. After installing them my windowing system was terribly slow. For a temporary fix you can try going to System Settings -- Desktop Effects -- Advanced and switch the Composting from OpenGL to XRender.

Worked for me, but if you specifically need opengl for something, you might have to fall back to the previous version of nvidias drivers (285 I believe).

Same problem on an on-board NVIDIA Corporation C73 [GeForce 7050 / nForce 610i] (rev a2); Intel(R) Celeron(R) CPU 430 @ 1.80GHz, 3 Gb of RAM.

Shift+Alt+F12 came quite handy after the upgrade form 11.10 to 12.04. That unlocked Plasma but I wanted to play QuakeLive (was extremely slow with 295.40).

As per suggestion 3 here, the Nvidia driver ver. 295.20 brought usable desktop effects back to KDE with no visible slow-downs (and fixed the Quake issue). Interestingly, Unity 3D, which was also affected, runs but with visible slow-downs under regular operations such as opening and minimizing windows, calling the Dash, etc.

Well, I was having this problem with my 2nd machine when I came upon a post at ubuntuforums that fixed it for me! Basically:

------

Firstly remove all the installed propietary driver from the Additional Drivers. Then type these commands into the terminal:

sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update
sudo apt-get install nvidia-current=295.33-0ubuntu1~precise~xup1

Finally just reboot, and the unity3D will work (or at least I'm hoping it )
Of course you mustn't upgrade the nvidia-current to the 295.40 version, because it brokes everything.

P.S.: I hope you didn't purge the whole ubuntu-desktop, because I see this in your comment...

-----

Make sure to lock the driver when you finish so that it doesn't update again.
