Find the line containing PowerStorm 300/350 X server command-line arguments.
Search for the text “

PowerStorm 300/350 Server args start

” and proceed to

the next line where the arguments reside.

Append a

–I

argument to the list if one is not already present. This indicates the

beginning of device-dependent arguments.

Append the

–riFlipVSync

argument to the list as follows:

! PowerStorm 300/350 Server args start

-pn –su –bs –nice –2 –I -riFlipVSync

! PowerStorm 300/350 Server args end

Save your changes to the

/var/X11/Xserver.conf

file.

Restart the server:

> /sbin/init.d/xlogin restart

To disable the synchronization, follow these same steps, but remove the

–riFlipVSync

argument. If no other device-dependent arguments are present, you may also remove the

–I

flag from the end of the list.

7.2.3 Default OpenGL Texel Size

When specifying a texture in OpenGL, the application may request the use of a particular
internal format for GL_RGB and GL_RGBA format textures. If the generic internal
format of GL_RGB (3 component) or GL_RGBA (4 component), are requested, the
implementation chooses which internal format will be used to store the texture.

The default behavior for our implementation is to use 16-bit texels for these generic
formats, as this will effectively double the number of textures that will fit in the texture
cache on the PowerStorm 300/350 graphics controllers.

To enable the use of 32-bit texels for these generic three and four component internal
formats, follow these steps to add a device-dependent X server argument:

Login to the system as root. Ensure that no other user is currently working locally at
the X console or connected remotely to the X server. You may choose to reboot the
system in single-user mode before continuing.
