How to get hardware acceleration?

Hi, I am having some problem getting hardware acceleration to work with my Intel i945GM graphics card and FreeBSD 10.0. Using glxinfo, I can see it says
Code:
direct rendering: Yes
but it also says
Code:
OpenGL renderer string: Software Rasterizer
and running glxgears -info, it shows
Code:
GL_RENDERER   = Software Rasterizer
too. Some of the 3D demos run very slow, and even watching a normal video uses a lot of CPU.

Anyone have any idea of what is going on here?

Read through /var/log/Xorg.0.log and look at the lines where it loads drivers and selects the driver. What's listed there? Is it actually using the correct driver for the i945?

It looks like it. Here's the relevant part of the file:

I don't really know what all of this means.

I am also having a problem with xeyes crashing X, unless I run it as xeyes +render. Not that I actually need xeyes, but it might be part of the same problem.

These are the old versions of xorg. To get the new one, you will have to update the ports tree and build from ports. See https://wiki.freebsd.org/Graphics#Installing_KMS_Ports.
We can also use the temporary WITH_NEW_XORG repositories instead of ports, isn't it? I somehow managed to transition from WITH_NEW_XORG ports to packages without major issues but I think that ports are no more strictly necessary for this purpose. *On the other hand, the fact that the above Wiki page has not been updated makes me doubt...* :q

* Edit: The Graphics Wiki page has just been updated.

pkg info -ix xf86-video xorg-server

glxgears -info


Output from glxgears -info did not help me to tell whether I have hardware acceleration.

glxinfo

This – not in the wiki – was more user-friendly. Thank you!

It appears that I have hardware acceleration without membership of the video group. (I'm an operator.)

Code:
% sh
$ env vblank_mode=0 glxgears -info
ATTENTION: default value of option vblank_mode overridden by environment.

… a problem to look at the maps on this site: https://www.dxmaps.com/spots/mapg.php?Lan=E

It says my browser doesn't have WebGL enabled. …

… Since I added my user to the video group I can see the map …

holala is this how the map should appear (to a not logged in user)?

Thanks to eternal_noob for reminding me of this topic.

… It appears that I have hardware acceleration without membership of the video group. (I'm an operator.) …

For test purposes, taking things further, after removing myself from all groups except grahamperrin then logging in, I do have direct rendering below.

Does this contradict what's currently in the FreeBSD Handbook? From <https://docs.freebsd.org/en/books/handbook/x11/#x-config-user-group>:

… Access to /dev/dri is needed to allow 3D acceleration on video cards. It is usually simplest to add the user who will be running X to either the video or wheel group. …

Does the mode of the symbolic link override the mode of the character special device to which the link refers?

In October, I spent some time seeking a more recent topic that was focused on hardware acceleration, I could not find one.
Personally i think when you don't expect an answer from the OP it can be a good idea to start a new thread.

For the DRI2/DRI3 question, I recall <https://cgit.freebsd.org/ports/tree/UPDATING?id=121ae90af1478922bd6e8e96a81f210a96806aa8#n8> (2020-03-08):

The mesa OpenGL library (graphics/mesa-libs) has been switched to use DRI3 by default, instead of the older DRI2 interface. This might cause regressions when using the legacy graphics drivers, either through graphics/drm-legacy-kmod or the graphics drivers in base.

If you experience issues when running OpenGL applications it is possible to force the use of DRI2 by setting the LIBGL_DRI3_DISABLE environment variable to 1 before starting any OpenGL application. The easiest way to do this is by adding it to either your shell startup files or .xinitrc.

<https://cgit.freebsd.org/ports/commit/?id=121ae90af1478922bd6e8e96a81f210a96806aa8>
