2.1 Does Blender support hardware accellerated Mesa or OpenGL?

Most important: always check the changelog for latest information. The current state of h/w support is:

SGI Irix: yes, all systems.

Sun Solaris: yes, but only OpenGL 1.2 works properly.

Linux:

    Riva TNT cards work now... but X still crashes occasionally with selecting. Wait for offical Xfree support.
    3Dfx/Voodoo doesn't work with Blender. It is a not-OpenGL compliant system and is only capable of running in a special framebuffer.

Windows: tested cards/systems:

    SGI Visual PC: OK, you just need to follow these instructions.
    Intergraph: OK.
    3DFX/Voodoo cards: NO! This is a not-OpenGL compliant system and is only capable of running in a special framebuffer.
    Riva TNT: Yes, but only with "DispView" option (F10 menu) active. TNT cards have problems with resizing windows.
    Permedia: Yes.
    Oxygen/3Dlabs/G200 cards are not tested here. We had reports it works fine.

BeOS: not available yet.

2.2 How do I get the numpad working in X?

The numpad is used in Blender to invoke all important view commands. It only works when the keyboard returns the 'rawkey' values, and not the corresponding numbers.

Here is an important line in the /etc/X11/XF86Config file:

............................................................
# To disable the XKEYBOARD extension, uncomment XkbDisable.

XkbDisable
..........................................................

Just comment 'XkbDisable', restart X and it should work fine!

Another possible problem are the presets in your ~/.Xmodmap file. These are codes Blender expects:

Numpad      Xk code

0      0xFF9E
1      0xFF9C
2      0xFF99
3      0xFF9B
4      0xFF96
5      0xFF9D
6      0xFF98
7      0xFF95
8      0xFF97
9      0xFF9A
/      0xFFAF
*      0xFFAA
-      0xFFAD
+      0xFFAB
.      0xFF9F


Or for example: make a file called .blender.xmodmap and put these keysym definition lines into it:

keycode 79 = 0xFF95
keycode 80 = 0xFF97
keycode 81 = 0xFF9A
keycode 83 = 0xFF96
keycode 84 = 0xFF9D
keycode 85 = 0xFF98
keycode 87 = 0xFF9C
keycode 88 = 0xFF99
keycode 89 = 0xFF9B
keycode 90 = 0xFF9E
keycode 91 = 0xFF9F

Then just run xmodmap .blender.xmodmap and every numpad key will work correctly in Accelerated X.
This example only works with NumLock on!)
