[i945] (Needs UXA) 1 fps in 3d apps like neverball with EXA (UXA fixes all but GoogleEarth,Earth3D)

Thank you for reporting this bug. Could you have a look at https://wiki.ubuntu.com/X/Troubleshooting/IntelPerformance and report if any of the workarounds there improves things. Also, please verify that the device file /dev/dri/card0 exists on your system.

Also, you have some options in your xorg.conf. Do you have the same performance if you rename xorg.conf so that the default options are used?

Hello,

I have renamed by xorg.conf to xorg.conf.bak and the problem remains.

I am about to try the other suggestions you sent through.

Regards
Graham

I can verify that the card0 file exists:

graham@graham-ubuntu:/dev/dri$ dir -l
total 0
crw-rw----+ 1 root video 226, 0 2009-04-10 00:12 card0

Hi,

My report on the given wiki page:

Problem: /dev/dri/card0 is missing.
Problem: /dev/dri/card0 permissions are incorrect.

    - The file exists on my install as follows:
        crw-rw----+ 1 root video 226, 0 2009-04-10 00:12 card0

graham@graham-ubuntu:/dev/dri$ getfacl /dev/dri/card0
getfacl: Removing leading '/' from absolute path names
# file: dev/dri/card0
# owner: root
# group: video
user::rw-
user:graham:rw-
group::rw-
mask::rw-
other::---

Problem: Falling back to OpenGL software rendering

graham@graham-ubuntu:/dev/dri$ glxinfo | grep render
get fences failed: -1
param: 6, val: 0
direct rendering: Yes
OpenGL renderer string: Mesa DRI Intel(R) 945GM GEM 20090326 2009Q1 RC2
x86/MMX/SSE2

Problem: UXA gives better performance than EXA - why not move to UXA?

    - This seems to have fixed the problem for me. Neverball and the
other 3d apps I use are now running silky smooth even with th desktop
effects set to full. Google Earth however is still maintaining 1fps.

Many thanks, and I'll keep you posted if I find any further problems
with this experimental driver.

If you have any ideas why Google Earth still likes 1fps I'd appreciate
it. It runs very smooth on my 'other' OS on the same PC (are we allowed
to say that?).

Graham

Thank you for the information. I know very little about 3d rendering, but I'm sure the information you provided is useful for those who know more. Usually, performance bugs are hard to deal with, but this may be easier since it has a very low performance (1fps) and you have provided a lot of useful information.

It seems that you have some output on STDERR from glxinfo:
get fences failed: -1
param: 6, val: 0
That may (or may not) be a key...

I have set the status to confirmed, and this is pretty much all I can do for you now (and I'll update the title to be a bit more specific in a sec).

No, those are innocuous warnings (I'd love to suppress them).

Thanks for doing this.

Given you have a GM945 and Xorg.0.log contains the lines
(EE) intel(0): Failed to set tiling on front buffer: rejected by kernel
(EE) intel(0): Failed to set tiling on back buffer: rejected by kernel
(EE) intel(0): Failed to set tiling on depth buffer: rejected by kernel

you are most likely seeing the "a17 swizzling" bug.

Could you please install the package xserver-xorg-video-intel-dbg, then run the command:
sudo intel_reg_dumper | grep interleaved

and paste the result here?

Hello,

Thanks for your reply. I will do as you ask as soon as possible however
my installation has completely died. When I updated to the latest kernel
release and rebooted I am left with a command-prompt that says something
about initramfs. I cannot proceed in to Gnome at all and have very
limited command-line knowledge on this OS.

I intend to download an installation disc to see if there is a repair
option on it and will also have a look on the forums for if anyone else
has experienced this before I will be able to respond to your request,
so please bear with me!

Regards
Graham

Only with 9.04:

All 3d applications (Like stepmania, wow with wine) show-me the same error before crash:

 get fences failed: -1
 param: 6, val: 0

but the glxinfo and gears show- me 3d enable ~~:

 direct rendering: Yes
 OpenGL renderer string: Mesa DRI Intel(R) 945GME GEM 20090326 2009Q1 RC2 x86/MMX/SSE2

glxgears (with UXA):

 Running synchronized to the vertical refresh. The framerate should be
 approximately 1/12 the monitor refresh rate.
 810 frames in 5.0 seconds = 161.932 FPS
 728 frames in 5.0 seconds = 145.378 FPS

glxgears (with EXA):

 2000 frames in 5.0 seconds = 400 FPS
 3000 frames in 5.0 seconds = 600 FPS

UXA is very unstable for I945.It somtimes freezes my system completely and I have to reboot manually by turning the power off.
One thing I noticed that whenever I boot windows first and then restart system and select ubuntu on my dual boot system I get this error.My CPU box has a memory indicator which gets turned off completely and I can see only freeze screen.
