[PyMOL] enable direct rendering DRI on fedora core 2

2004-06-11 Thread Dr. Daniel James White PhD

Hi everyone!

how can I enable direct rendering DRI on fedora core 2?
I have an ATI radeon 8500 LE,

Should I use the redeon driver, or the r200 driver?

I edited my xorg.conf file is  as below, but VMD and pymol tells me I 
am still using indirect mesa rendering, and it is SLOW.

the ATI closed source driver doesn't work on the fedora 2.6 kernel so I 
cant use that.

# To customise the XKB settings to suit your keyboard, modify the

# If you have a US Microsoft Natural keyboard, you can use:

# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:

# or:
#   Option  XkbLayout de
#   Option  XkbVariantnodeadkeys
# If you'd like to switch the positions of your capslock and

#   Option  XkbOptionsctrl:swapcaps
# Or if you just want both to be control, use:
#   Option  XkbOptionsctrl:nocaps

You want the 'r200' driver. See:


There are actually two drivers at the X level, called 'r200'
and 'radeon'. 'r200' is for Radeon 8500 and up, 'radeon' is for
older Radeons. Confusingly, they both use the same kernel level
driver which is *also* named 'radeon'. But the driver you
specify in the xorg.conf is the X level one.

Also, if your card is PCI rather than AGP, there may be some extra
work you may have to do...
