Bug Description

I'm experiencing issues similar to the ones described at:

  http://www.nvnews.net/vbulletin/showthread.php?t=154563

Switching font rendering from 'Subpixel Smoothing (LCD)' to any other setting in 'Preferences -> Appearance' makes the problem go away.

Yes I can confirm there is a regression issue with xserver 1.9 (at least up to 1.9.0-0ubuntu4) and nvidia-current (at least up to 256.53).

This is most prominent when scrolling in some applications.
I have found that synaptic is a very good example of this one.
Scrolling is severely influenced there.

With xserver 1.8 branch and nvidia-current 256.44 scrolling was very fluent:
a big difference compared to xserver 1.8 branch with ati open source drivers (xserver-xorg-video-radeon).
Now the open source ati drivers are clearly faster than nvidia-current_256.53 with xserver 1.9.

But, for the time being I cannot say if this is a regression in xserver 1.9 or have certain codes changed in the new xserver so much,
that nvidia drivers ought to be changed as well.
At least it seems not to be a regression in nvidia-current, because the same driver (256.44) works very well with xserver 1.8, but not with xserver 1.9 (with IgnoreABI command).

Harry (harry33) wrote :

Just out of curiosity,
could this bug have something to do with desktop sluggishness that was observer to be caused by libcairo?
The libcairo code was temporarily changed in order to overcome the incompatibility with nvidia-current back then.
See the bug #605979

And one more thing.
This bug does not in any way affect video performance. HD videos (1920:1080) run really well.

I encounter this issue as well (nvidia 256.53, Meerkat beta). BTW, the IgnoreABI option doesn't seem to be required anymore as of today.

(i.e. : playing HD videos or OpenGL apps are smooth -- scrolling text or moving a window about a window that is full of text is *extremely* slow, while it's still as smooth as it used to when moving a window over a window that doesn't contain text)

and switched back the font settings to "Subpixel Smoothing (LCDs)", and...

the problem hasn't gone away. There is still a clear speed drop in, say, simply scrolling text in the command prompt.

Like Daniel wrote (comment 10), this beta driver does not yet contain that bug fix.
It will be included into the next version, perhaps into the stable 260 series driver.

Partially solved: i completely removed everything and just reinstalled, for some unknown reason it was still loading the old driver.
However, i've completely lost v-sync, be it xvideo textures, compiz or everything else, it just doesn't sync anymore: the new driver completely resolves the font issue btw.

Given all the warnings about borking Ubuntu by installing nvidia website drivers (and the fact that I tried it and ended up borking Ubuntu), I'm not sure if that is such sound advice...

Glad to hear some people know how to do such things, though :) I'll wait patiently for a Maverick package.

Thanks for the hard work.

Just wanted to let you all know that the updated nvidia driver is in Philip Johnsson's Extra PPA:
https://launchpad.net/~philip5/+archive/extra

I used that to install 260.19.06 in Maverick and it works like a charm, no performance regression using antialiased text anymore.
After installing just the updated nvidia packages from that PPA, disable it.

GL&HF. :)

Harry (harry33) wrote :

Yes I confirm what maba just wrote in comment #22.
I only downloaded the packages nvidia-current and nvidia-settings from that PPA.
Then I installed them with dpkg in terminal.
There is no need to change sources.list that way.

Anyway, the driver runs well in maverick too. The PPA itself is for Karmic and Lucid.

I have not seen any instability issues with the new beta driver 260.19.06 in my maverick 64-bit setup.
The sluggishness issue is completely gone and also gnome-shell works fluently now.

Please pay attention to that Brandon Snider has uploaded this new beta driver (nvidia-current) in X Updates PPA:
https://launchpad.net/~ubuntu-x-swat/+archive/x-updates
It is built both against lucid and maverick.

Note also that the X updates lucid build cannot be installed on maverick.
The lucid package nvidia-current provides virtual package xserver-xorg-video-6, which would break mavericks xserver 1.9.
The maverick package nvidia-current provides virtual package xserver-xorg-video-8, suitable for xserver 1.9.
Note also, that this is the way it should be.

This bug was fixed in the package nvidia-graphics-drivers - 260.19.06-0ubuntu1

---------------
nvidia-graphics-drivers (260.19.06-0ubuntu1) maverick; urgency=low

  * New upstream release:
    - Fixed an interaction problem with a change in X server
      behavior that caused slow text rendering on X.Org xserver
      1.9 (LP: #629910).
    - Enhanced VDPAU to support interop with CUDA and OpenGL
      when Xinerama is active.
    - Fixed a bug in VDPAU that prevented temporal-spatial
      de-interlacing from operating when temporal de-interlacing
      was not also enabled.
    - Added support for configuring the dithering depth used when
      driving a flat panel with a GeForce 8 family or Quadro
      4600/5600 or newer GPU. See the "Dithering Controls" in the
      Flat Panel page in nvidia-settings.
  * debian/headers, nvidia-current-dev.install{.in}:
   - Put the headers from 256.53 in debian/headers and install
     them in nvidia-current-dev as usual. Starting from the 260
     series, these headers are no longer distributed with the
     Nvidia installer. In Natty we'll package them separately
     but for now we'll keep them in nvidia-current-dev.
  * debian/dkms/patches/nvidia-2.6.36-ioctl.patch:
    - Refresh patch.

The 260.19.06 beta did in fact solve all my issues.

And I think my issues were related to font rendering, so I used to have poor performance when scrolling a verbose script in terminal, etc.

  @ Magnus
I also thought 260.19.06 solved the issues for me. For example, another
'common' regression which seemed to be solved was scrolling in Firefox
(Chrome wasn't affected, at least not for me). But, what I didn't
mention in my previous post is that for me this works only after a
(re)start and only for a certain period of time (maybe it depends on the
number of open applications). I'm not sure if this is the same problem
as the one reported by eZFlow and Extender or something only I
encountered. Nevertheless, it seldom happens to work properly and only
under light system load.

Are we getting an update to 260.19.12 which is the latest certified driver from NVIDIA instead of the Beta we are currently running?

Hello,

I'm also suffering from performance problems in gnome-terminal and others. Switching on and off again the "Desktop Effects" makes it go away for a while.

Is there a place where one can get the new nvidia package (260.19.12) as a Ubuntu .deb?

Yes, of course, it's Ubuntu x-swat PPA. Even newer version is there.

It seems I just ran into this problem on Ubuntu 12.04 (final beta) with nvidia's binary drivers v295.40, using XFCE. Geany would randomly become extremely slow, sometimes taking seconds to update the text view. Whenever this happened, Xorg used 60-100% CPU. Switching off subpixel rendering in XFCE's display settings fixed it.

Sorry, I spoke to soon: Switching off subpixel rendering was only a temporary fix; the problem is suddenly back. Worked for a good while though (tested a while before posting the previous comment).

Gerry, unless you need fast 3D, simply use Nouveau instead.
