Do you use hardware 3D acceleration in Linux?

I'm wondering, how many Linux users use hardware 3D acceleration drivers (for OpenGL) in Linux, and if not, why not
-no hardware that supports it (do such video cards even exist today?)
-ideological reasons
-no need for it
-no drivers available
-other reason?
By 3D hardware acceleration I mean true drivers that use the graphics cards 3D hardware to render anything (even 2D textures), such as the NVidia or ATI drivers.
Mesa Software Rasteriser drivers appear to be the alternative if you don't have 3D accelerated drivers, so if you have these, please answer No.
I'm asking this to figure out how many Linux users I'm excluding if I create software that requires hardware 3D acceleration.

Running an HD4850 on the open-source xf86-video-ati drivers, so thats the "radeon" driver.
I run without a xorg.conf, so getting that configured properly... No need
2D works splendidly. Besides the normal apps on your desktop I also play Battle of Wesnoth from time to time, and I recently installed StarCraft using Wine. To get in the mood for StarCraft II, my little bro is a beta tester.
3D works, I run a composite desktop which works great. I also tried QuakeLive, runs terrific.
I haven't been able to get Sauerbraten to run properly. Well the game runs properly, but the graphics doesn't (a lot of stuff is see-through for me). But as the drivers improve, I expect things to get better. Performance optimizations would come after that. So that is still a work-in-progress but the basics are there.
For serious 3D gaming I hop over to the Win7 install. Set that up that specifically for the purposes of gaming. Helps to keep my productivity up

ATI Primary and Nvidia Secondary for Hardware MPE Acceleration

Hi everyone,
I'm not sure if this has been discovered yet. I think it is very exciting, and very important for anyone with an AMD (ATI) GPU who wants hardware MPE acceleration.
It is possible to use Hardware MPE acceleration while using an ATI video card as your primary adapter, and a lesser CUDA Nvidia GPU as a secondary adapter not connected to any monitor.
My system:
CPU: 1090T
Mobo: 890GX
RAM: 8 1333
RAID: No
GPU1: 5870
GPU2: GTS 450
As you can see, I have a Nvidia and AMD GPU in the same system. The 5870 is obviously by far the most powerful of the two, and it is what I use to record rendered footage using FRAPS.
Recently, I became aware of the powers of hardware MPE. I concluded that the best way to obtain HMPE and maintain my FRAPS recording was to purchase a GTX 480. However, this was out of my wallets league as I could not sell the 5870.
I was already aware that PhysX (A CUDA physics calculation library) could only be run on Nvidia CUDA GPUs (Like HMPE). Many Nvidia card users used secondary CUDA cards to accelerate physics calculation in games. ATI card users could not use a secondary Nvidia card for physics calculation as the Nvidia driver locked down PhysX in the presence of an active ATI GPU. Luckily a clever fellow called GenL managed to hack the Nvidia drivers to force PhysX to work in the presence of an ATI GPU.
I hypothesised that if I performed that hack, HMPE would gain access to CUDA in a similar fashion to PhysX, thus allowing me to buy a far cheaper GTS 450 and pair it as an HMPE renderer with my 5870. After buying a GTS 450, I failed at implementing the hack and was about to give up.
HMPE worked when my monitor was connected to the GTS 450, but if i tried to start PPro with the 5870 connected to any monitor HMPE was unavailable.
I had two monitors connected to my GTS 450, and was playing around with adding stupid amounts of HMPE accelerated effects to an AVCHD clip. Realising that it was impractical to constantly switch the DVI cable from 5870 to GTS 450 I decided to leave my primary monitor connected to the 5870 and give up on HMPE. So, I reached around behind my computer and did it, but crucially did not quit PPro before I did so.
When the screen flickered back to life, the yellow HMPE preview bar was still yellow. The timeline still scrubbed perfectly smoothly. HMPE was still working with a 5870 as the primary monitor: The PPro window was on the 5870 monitor, and the 5870 was rendering the window!
I found that provided I did not close PPro, I could switch between HMPE and SMPE at will, all while using the 5870 as the primary adapter.
I tested this using a 10 second composition of 3 AVCHD 1920x1080 Clips with CC, drop shadow, gaussian blur, edge feather, Basic 3D, transform, Ultra Key, drop shadow applied, rotatating amongst each other. I could still switch even if the 5870 was the only card connected to a monitor.
Rendering this test clip via PPro direct export takes 30 seconds in HMPE mode with the 5870 and 1.43 in SMPE mode with the 5870.
However: Rendering performance in AME stays the same whether I selected HMPE or SMPE. I believe this is because AME is a separate application that 're-detects' the ATI card and disables HMPE before beginning the encode, in the same manner that restarting PPro while using the 5870 removes the HMPE option. Rendering the clip in SMPE and HMPE modes using the GTS 450 gave the same 30 second vs 1.43 minute result.
Therefore, as long as you are happy to encode via direct PPro export you will still see the benefit of HMPE while using an AMD card as the primary adapter.
I hope this is as terribly excited to other users of ATI cards as it was for me. This has saved me several hundred dollars.
Cheers,
NS2HD

Interesting results. I own a system manufactured by BOXX, a system developer out of Texas who really knows their stuff. I had asked them if it would be possible to purchase a CUDA enabled card and put it in my secondary slot and use it for MPE while maintaining my current (nvidia) card to run my monitors (also giving me the ability to run four screens). They said that no, according to the Adobe developers they were working with, Premiere could only use MPE off the CUDA card if the monitor previewing your work was plugged into that card. I guess they were wrong!
Also, from my understanding, you don't see lesser results with AME because it's a separate program that starts separately, you see the lesser results because it has not yet been coded to take advantage of CUDA.

2D GPU acceleration for Linux Reader 8 (when it will be available)?

It would be nice if Adobe Linux Reader 8 could use "2D GPU Acceleration" in Linux too. It could be done using OpenGL driver. Nvidia Linux Geforce driver has support for shader technology in Linux too. ATI also uses its own accelerated OpenGL library in Linux.
Will Adobe make Linux Reader 8 with 2D GPU acceleration?

What a pity. Adobe reader is very slow even on fast machines when compared to open alternatives. 2D GPU acceleration could give a chance to Adobe Reader to work at least equally fast as open source viewers.
However thanks for reply.

How to use hardware acceleration in Swing?

Hi,
I searched in net and could not find anything clear on hardware acceleration using Swing.
To use the hardware acceleration, do I need to specify
-Dsun.java2d.opengl=true ? Is this must?
Without specifying this, Java 2D calls wont use hardware acceleration?
Kindly clarify. I could not able to find anything in net for this.
I am having ATI Radeon AGP card and using Linux as OS. I have installed the ATI driver. Now I need to know how to interact with hardware using Swing.

Hi,
I searched in net and could not find anything clear
on hardware acceleration using Swing.
To use the hardware acceleration, do I need to
specify
-Dsun.java2d.opengl=true ? Is this must?No. I've never seen that before. My assumption is that you'd do that if you wanted to make sure you're using OpenGL and not DirectX. Swing will make use of 2D hardware acceleration on it's own. Don't specify anything special.

[SOLVED] Firefox 28 stopped using hardware acceleration

Up to Firefox 27, one could start Firefox with
MOZ_ACCELERATED=1 MOZ_GLX_IGNORE_BLACKLIST=1 firefox
or you could set
layers.acceleration.force-enabled=true
in about:config. Then you could check, whether Firefox uses hw-acceleration in about:support. There should be written something like "GPU-accelerated windows 1/1 OpenGL" instead of "0/1 Basic".
Since Firefox 28, this doesn't work anymore and graphical glitches came back (see here: https://bbs.archlinux.org/viewtopic.php?id=178024)
Any ideas/hints?
EDIT: nvidia 334.21-2, linux 3.13.6-1

I'm suffering the same issue here, using nouveau drivers.
Just to throw it out there, I'm convinced nobody packaging for arch broke anything this time , I lost this capability using aurora (installed locally from mozilla ftp) some time ago but didnt really notice/look until version 29.
Nevermind, I seem to have fixed it after some searching: http://featherweightmusings.blogspot.co … refox.html
export MOZ_USE_OMTC=1
layers.offmainthreadcomposition.enabled ==> true

Flash Player often crashes if using hardware acceleration.

Hi, guys. Flash Player crashes. It crashes when the "Use hardware acceleration" checkbox is checked. And it crashes so bad, that only the Reset button helps.
My PC is flawless. I'm running Winsows XP x64 SP2 (latest service pack for this OS), Nvidia Geforce 8600GT with latest drivers, DirectX 9c, Flash Player 10.3.
If I disable hardware acceleration in the Flash Player settings, there are no crashes. Without HW acceleration videos are a little aliased and ugly.
Why is that happening?

Hi,
I'm sorry you're running into these problems. Could you follow the instructions on our video troubleshooting page and in addition to opening a bug report, please send the results to me at [email protected]? I'll take a look and see if I notice anything out of place.
Thanks,
Chris

How to check whether Java 3d is using hardware acceleration?

Hi
I just started looking into Java3d api. I am going through the tutorial examples. When I run it on Windows with JDK1.4.2, the app runs, but taskmanager shows cpu usage is around 55% of my 3GHz Intel processor.
I am sending the following VM parameters
-Djava.library.path=C:\progra~1\Java\Java3D\bin -Dj3d.rend=ogl -Dj3d.debug=true
I tried Direct3D as well by passing -Dj3d.rend=d3d. I don't see much difference in cpu usage. The sample I am playing is the one where you create a ColorCube and rotate it on a timeline. Pretty straight forward code taken from the tutorial.
I am wondering
a) Why is my cpu at 55% if it is using h/w acceleration?
b) Is there any way to find out whether Java is using software renderer vs h/w renderer.
I used sys internals processexp tool to look at the stack of java thread that is spinning the cube. I don't see any references to opengl or j3d dlls in the call stack.
I appreciate ur help.
Thanks

check this link, it queries the properties of your system:

Is JMF use hardware accelerated through JNI possible?

Dear all:
I try to use JMF decode MPEG-2 data, through VeXP which wrote in C.
So I think we can call C library through JNI pass encoded MPEG-2 data to VeXP, use hardware decode encoded MPEG-2 data to YUV-format raw data then return it to JAVA.
but JNI seem can't pass media raw data by call by reference...
It should cause a lot of memory copy.
How about it's feasibility?
Have anyone give me some suggestion?
Regards,
white

There's a few ways to do it, but I'd use a style sheet. So:
1. Add this to the "creationComplete" Stage event: sym.$("<link rel='stylesheet' type='text/css' href='styles.css'>").appendTo("#Stage");
2. Create a style sheet (text file) in your project folder named "styles.css", and define a class:
.force-webkit-acceleration {
-webkit-transform: translate3d(0,0,0);
3. Give your animated element the class "force-webkit-acceleration" in the properties panel (the little c-in-a-box icon next to the title field).
Be sure that the style sheet file ends up in your "publish/web" folder too.

Do you use mac's default mouse acceleration?

I know there are billions of Mac users and if you use Apple's mouse, do you ALL turn OFF mouse acceleration or you get used to it?
I find it weird, but my mouse is not moving as precisely as I want. Because when I move it slower, the mouse is not moving as I expect. It is changing its speed and it is hard to predict it.
When I follow the general recommendation and turn the acceleration off by this command: defaults write .GlobalPreferences com.apple.mouse.scaling -1
I don't like it either, because it is becoming too sensitive: when I move it a little, it is jerky.
So, my question to all mouse users, do you really use default mouse acceleration? Or what do yuo do? Will I get used to it?

No, sorry, I don't know if this is possible. But here in this forum people who know the Mac product won't see it.

Which software do you use on the linux or unix platform

I am learning oracle, so I am wondering, in the real world, which software do you use to administrate oracle in the company, on the linux or unix platform? sqlplus?
certainly, I think you can also open the OEM GUI in linux or unix

If you are learning, surely enough , learning any o/s other than windows will help. About the industry, there is not just one player that rules in the o/s market. It depends on a lot of factors , cost being the most dominating one. Linux, being a little less costlier, is surely a good choice for many but so is HP UX or AIX. Without bothering about what is more popular, learn one which you can get your hands on in your learning environment more easily. For example, it would be tough to have a AIX based machine in your home and a linux based would be lot easier. So learn one, ,learn it good. When you go to a different shop, use your previous knowledge and learn the know-hows of that o/s as well.

Got a new Mac Book Pro for school. Go to update all the hardware and software do not have any problems until i get to "iMovie" and "iPhoto" (they came pre-loaded) and i get "To update this application, sign in to the account you used to purchase it." help

Does any one know how to fix this problem?

Should be the account you registered your mac with, and/or the account you used during the setup assistant.

What is the use of BI ACCELERATOR

What is the use of BI ACCELERATOR

Hi,
B.I Accelerator
BI accelerator is a separate hardware which when attached to BW server creates an index on data of infocube and stores in compressed format.Different technologies are used for compression and horizontal pratitioning of data.
BI Accelerator can benefit businesses that have high volumes of data. The read
performance of BI queries is greatly improved using BI Accelerator. This new
tool enables quick access to any data with a low amount of administrative effort
and is especially useful for sophisticated scenarios with unpredictable query types,
high data volume and high frequency of queries.
BI Accelerator is also useful when aggregates or database indexes are not
sufficient, or when these methods become too complex or too costly to maintain.
For example, it may not be practical or cost effective to create and maintain all the
aggregates that are needed to support performance for all queries for an InfoCube.
BI Accelerator Pre requisites
-->BI Accelerator must run on a Suse Linux Enterprise Server 9.
-->An RFC Destination must be created between the BI System and BIA.
-->BI InfoCubes that contain non-cumulative key figures are not supported by BI Accelerator at this time.
-->BI Accelerator requires SAP Netweaver 2004s SP4 or higher.
There are two major components in the BI Accelerator architecture that contribute
to the high performance:
. BI Accelerator Engine
. BI Accelerator Indexes
The BI accelerator is fast enough to aggregate BIA indexes during run time.
A BI Accelerator index contains lists of Index names, join conditions, join paths, view attributes, semantic relations, and key figures.
BI Accelerator indexes are independent indexes that store meta data, as well as, execute queries.
BI Accelerator is a very robust and stable environment that uses simple algorithms versus volatile DB optimizations.
BI Accelerator is also model-driven:
integrates NetWeaver BI with the TREX search engine, BIA indexes are a special case of the ESA business object, distinctive SAP technology is leveraged.
TREX and BI Accelerator
TREX : Search and classification engine, mainly for unstructured data
BI Accelerator is built using TREX technology (indexing, retrieving, compression ...) to handle structured data
Note: BI Accelerator and TREX are two different installations.
The BI Accelerator cannot be used for standard KMC functionality
A TREX installation cannot be used as a BI accelerator
Technically there is a lot of commonality but TREX-BI Accelerator role switching is not supported.
BI Accelerator index: Structure containing replicated data and indexes (one index per table) that
represents the BI star schema for the BI Accelerator
Indexing: Transfer of InfoCube data to the BI Accelerator server and
processing and compressing it into the BI Accelerator index.
To use a BI accelerator index for an InfoCube when you execute a query, you first
have to activate it and then fill it with data The system performs the following steps
in order to create an index
Create
Index
Prepare optimize
Commit optimize
Advantage Of B.I Accelerator
Advantage of this is that whenever a query is executed ,Data is fetched from BI accelerator instead of reading of reading frm database reads.
Thus DB read time is 0 in total query run time leading to improved query performance and stable query response time.
Increased end-user satisfaction with consistently high query performance.
Significant reduction in the total cost of ownership: low maintenance, high scalability.
The performance gain using BI Accelerator can be very great, boosting the response time by a factor of 10-100

Hardware Graphics Acceleration

As many users have noticed, there’s a new feature which is introduced in Office 2013 called "Hardware Graphics Acceleration", which sometimes is also called as "GPU rendering". The purpose of course is to improve performance.
As stated in the System Requirements for Office 2013, Graphics hardware acceleration requires a DirectX10 graphics card and a 1024 x 576 or higher resolution monitor.
A graphics processor helps increase the performance of certain features, such as drawing tables in Excel 2013 or transitions, animations, and video integration in PowerPoint 2013. Use of a graphics processor with Office 2013 requires a Microsoft DirectX
10-compliant graphics processor that has 64 MB of video memory. These processors were widely available in 2007. Most computers that are available today include a graphics processor that meets or exceeds this standard. But, if you or your users do not have
a graphics processor, you can still run Office 2013.
(http://technet.microsoft.com/en-us/library/ee624351(v=office.15).aspx)
The option of hardware graphics acceleration can be found in any Office applications from
FILE -> Options -> Advanced ->
Display -> Disable hardware graphics acceleration:
This setting can be controlled by the following registry key:
Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure
that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry,
http://support.microsoft.com/kb/322756
HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Common\Graphics
DWORD: DisableHardwareAcceleration
Value: 1 to disable, 0 to enable
Administrators can deploy this setting using Group Policy as well. Follow the steps below:
Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these
problems can be solved. Modify the registry at your own risk.
1. Add the following files to your domain controller: Office15.admx and
Office15.adml files to your domain controller and then
2. In the Local Group Policy Editor, select the Miscellaneous node of the
Microsoft Office 2013 tree. This setting is shown in the following figure.
For more information about how to use .admx and .adml files for Group Policy administration, go to the following Microsoft TechNet website:
How to manage Group Policy ADMX files
Please note the change is global: Changing this option in a single Office program also applies to other remaining Office programs. So you don't need to follow these steps for all Office programs one by one. If you want to just disable animations in Word
but leave them on in Outlook, no we can’t.
When do we need to disable Hardware Graphics Acceleration?
I’ve seen in some cases users complain that Office Applications are laggy and slow, sometimes even hang/freeze. They have tried many things but couldn’t figure out the root. Actually, the animation sometimes can slow the performance down, once they disable
the Hardware Graphics Acceleration, the problem is gone.
There are also issues like blurred text/font, cursor hangs randomly in Office applications, we can disable this simple option to see if this fixes the problem.
Please note, the Hardware Graphics Acceleration option is not the only option that may cause issues. For example, an user needs to turn off the animation to improve the performance of Excel, but it doesn’t have any effects after disabling Hardware Graphics
Acceleration. Now let’s check this Windows setting:
On the Desktop, right click on This PC(or Computer) icon, select
Properties, then Advanced system settings on the left side, under
Advanced tab, click on the Settings button for
Performance.
Now we see this:
Uncheck the box for Animate controls and elements inside windows, click
OK button.
Now the problem should be gone.
Another case:
If you have blurred text/font issue in Word, you may consider to disable Hardware Graphics Acceleration. If this doesn’t help, what to do next?
Please go to FILE tab -> Options ->
Advanced -> Under Disable hardware graphics acceleration, there’s a checkbox for
Use Subpixel positioning to smooth fonts on screen, uncheck it and click
OK. The blurred text/font should be gone.
Summary
In this article I introduced how to configure Hardware Graphics Acceleration from applications, the registry and Group Policy. There are also some issues it may cause and what we should do to resolve them. If you have any ideas about this topic or any other
comment, please feel free to post in the forum, thank you.
