kernel log

Using recent nouveau versions I?m encountering missing graphics in various
programs (e.g. gtk?s filechooser, LibreOffice, Iceape, Pidgin, xfce4-panel?s
pager and on lightdm?s gtk-greeter).
Moving the mouse cursor over these places or resizing the windows makes the
icons appear sometimes (but also disappear in the same manner).

Tested broken (Debian package) versions are:
0.0.16+git20120529+ace77b6-1
0.0.16+git20120614+36d3f8c-1
1.0.1-1

0.0.16+git20120322+ab7291d-1 was (and still is) working fine.

Kernel version is 3.4.4
libdrm 2.4.33

Hi Gerrit

I suspect that you're using AIGLX, and currently there are some known issues
with it. It is caused due to the dri module (nouveau_vieux_dri.so) being build
against the old libdrm interface, whereas the (problematic) ddx is built
against the new one

Note that this would be resolved when the distributions start using mesa 8.1,
as the dri module provided with it is based on the new libdrm

To quickly check, please disable AIGLX in your xorg.conf

If you're still having problems with AIGLX switched off, can you bisect - it
should take 5-6 steps

Thanks

I have an NV17 [GeForce4 MX 440] card, and I have similar rendering issues.

The issues are started for me after this commit (the new libdrm port):
http://cgit.freedesktop.org/nouveau/xf86-video-nouveau/commit/?id=e70d801ae9287eab5e82f4d467dc8cd4be1b31a8

So I think the problem is in this commit or in the new libdrm.

The graphics corruption, what I experienced sometimes:
- Missing icons in Nautilus.
- The toolbar in Nautilus and the tabs in Firefox are shown brighter than it
should be.
- The text in GNOME Terminal is shown in other color than it should be.

These problems are usually disappear, when I move the mouse over the elements
or move the application's window.

I'm using GNOME 3 fallback mode.

Same for me, I use a Geforce 4 MX440 and it always worked fine until I tried
the latest Ubuntu/Lubuntu/Xubuntu version. 

The following problems occur:

1. On Ubuntu the Unity panels do now show
2. On Xubuntu (XFCE) it works (quite fast), but the terminal text has the color
of the window below (goes away when moving window). Also, there are other
drawing issues with the panels of the default file manager and so on. However
most applications (like FireFox and Chromium) work as expected
3. On Lubuntu the terminal text is ok, but there are also issues with the file
manager and other LXDE apps
4. All desktop versions seem to have issues with radio-buttons, check-boxes and
so on. The color and brightness are not correct.

Is seems that the speed of the new nouveau driver has increased significantly
on the MX440, but at the cost of (some) compatibility.

This bug gets much more intense if RGB subpixel hinting is enabled but it
rarely appears if only grayscale antialiasing is used. Disabling the
acceleration makes it completely disappear.

I'd like to add that I have experienced a similar bug under a new
installation
of Lubuntu 13.04 where the mouse pointer and certain icons disappear when
hovering over them. Text also tends to turn green.

This has happened with NV10, NV11 and NV17 videocards.
Installing an NV34 (FX5200) videocard resolved the issue.

I have an NV17 ( NVIDIA Corporation NV17 [GeForce4 440 Go 64M] (rev a3) ) and
the same problems. 

Unfortunatly it's a notebook (that would be still fine from my point of
view)
and so i can't change the graphic card.

I attach some screenshot made with xubuntu 13.10 beta2 with the problems in
gimp, terminal and the missing icons in thunar.

Thank you.

I just recently had this same problem with my old desktop with the same
graphics card.

My problem: I'm still a novice in Linux. I started out with Xubutnu 13
awhile
ago, then found out it's not a bug but i support issue. *ubuntu 13 maybe
even
12 only supports Xorg server 11 which doesn't support Nvidia driver 96.**.
So i
downgraded to Xubuntu 11 which automatically installed my graphics card but
after a couple ppl told me its not a good idea to switch to unsupported OS and
i found out Debian 7 is current and still supports older Nvidia drivers. When i
switch to Debian 7 it doesnt auto install so i had some problems there but
nothing to complex. and for the missing icons and such (which isnt a problem in
Debian 7) just go to Settings> Appearance> Fonts tab uncheck "Enable
Anti-Aliasing and/or Icon tab and switch the icon option.

My Fix: Here's a link to a forum i posted on with the fix
http://www.linuxquestions.org/questions/showthread.php?p=5078340#post5078340

Hopes this helps!

--- Comment #20 from Orestis Gklavas <oglavas at gmail.com> ---
The issue is present in the latest Lubuntu version 13.10 with NV11 and it
manifests also in the form of disappearing text while scrolling through pdf and
disappearing table borders in libreoffice. It seems to go away once font
antialiasing is turned off.

This bug completely dissappears when I enable "ShadowFB" in the
xorg.conf file.
This works perfectly, if a little slower, except that all of the menu text in
LibreOffice disappears when ShadowFB is enabled.

--- Comment #22 from Eugenij Shkrigunov <eshkrig at gmail.com> ---
Enabling "ShadowFB" (i.e. disabling acceleration) is not a solution or
even a
workaround. Work at the terminal (LTSP, remote X11) becomes a torment.
A recent trend - disable acceleration instead of solving problem. A similar
situation exists with the xf86-video-sis.
Please fix the problem.

I have just tried lubuntu 14.04 beta2 with my nv17 ( ( NVIDIA Corporation NV17
[GeForce4 440 Go 64M] (rev a3) ) ) on a Compaq Presario r3445ea and the
situation is even worser than before... it doesn't even boot :(

Here is a photo with nouveau errors (last image, the previous were with lubuntu
13.10 that was only quite unusable due to missing text-graphics):

If there is a way to send more info i'll try to do so.

Thank you in advance.

Aha, and another issue which should be fixed by:

Please try applying both of these and see if that fixes things.

This patch alone does not help (see comment 10 and 11). Although I would
suspect it's because of the incorrect mask (fixed by the patch linked in
comment 25). Or in other words - there is more than one bugger, thanks for
tracking them down :)

These patches are now in git, and a number of people have confirmed that
similar issues are fixed. Please give the latest git code a shot (or nouveau
1.0.11 when it's released).

Hello, I came across this bug after installing Lubuntu 14.04.1 and experiencing
the disappearing icons in the default file browser and other places. I turned
off anti-aliasing under Settings>Appearance>Fonts and the icons no longer
disappear. This however makes the text harder to read. 

The title of the bug includes NV10 and NV20. I am just a regular user (not a
developer) but the fix below appears to only reference NV10. I have an Nvidia
GeForece 3 Ti200 graphics card which is considered NV20. Does the fix also
correct the issue for NV20 graphics cards?

fix
> also correct the issue for NV20 graphics cards?
NV20 uses the same accel logic as NV10 for exa. Reports are that it does indeed
fix the issue for NV20 iirc. xf86-video-nouveau 1.0.11 is now released and
should contain this fix.

--- Comment #30 from BobbyJ <junkbubba2 at gmail.com> ---
Thanks for the quick response. So it sounds like this fix should correct the
issue for NV20 cards. The current nouveau package for Ubuntu 14.04 LTS is
1:1.0.10-1ubuntu2. I assume this is the same package used for Lubuntu. 

Do you know how I would go about requesting that this change be backported to
1.0.10? Would I have to create a bug report on Launchpad or is it sufficient to
reference this bug report and fix?

There is no stable branch for xf86-video-nouveau (so no backporting). Upgrade
to 1.0.11, or ask your distro to add those in as extra patches.
