PowerStorm 300 AGP and 300/350 PCI Graphics Controllers 7–3
3.
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.
4.
Append a
–I argument to the list if one is not already present. This indicates the
beginning of device-dependent arguments.
5.
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
6.
Save your changes to the /var/X11/Xserver.conf file.
7.
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:
1.
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.
2.
Edit the file
/var/X11/Xserver.conf. Save a backup copy.
3.
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.
4. Append a
–I argument to the list if one is not already present. This indicates the
beginning of device-dependent arguments.
5. Append the
–riDefaultTexel32 argument to the list as follows:
