How to add OpenGL support?


Hi! I install Linux Slackware 9.0 but Gnome and KDE are very slow I think I need to add OpenGL support to Linux to make X more fast. My computer is:
Intel Celeron 1.2Ghz
256 Mb Ram
Audio - Video Integrated to i815 chipset.
Thanks.

opengl will not speed up 2D for you, unless you're using
directFB (but since that is not installed by default, your
2D/desktop performance will not increase when you
install hardware accelerated drivers).

and please explain which part of gnome / kde are slow?

have you got a NVIDIA chipset Video Card?

install the latest Drivers, do the proper modifications to XF86Config, select the correct Horizontal and Vertical Refresh of your monitor, change "nv" to "nvidia", set "(your resolution)/85Hz" and then restart X server...

Here is some peaks of my XF86Config, i have a PIII 750 Mhz with a Geforce2 MX and KDE has a Good Performance

PHP Code:
Section "Module"

# This loads the DBE extension module.

    
Load        "dbe"      # Double buffer extension

# This loads the miscellaneous extensions module, and disables
# initialisation of the XFree86-DGA extension within that module.
    
SubSection  "extmod"
      
Option    "omit xfree86-dga"   # don't initialise the DGA extension
    
EndSubSection

# This loads the font modules
    
Load        "type1"
    
Load        "freetype"
    
Load        "speedo"

# This loads the GLX module
    
Load       "glx"

EndSection 
PHP Code:
# Any number of monitor sections may be present

# HorizSync is in kHz unless units are specified.
# HorizSync may be a comma separated list of discrete values, or a
# comma separated list of ranges of values.
# NOTE: THE VALUES HERE ARE EXAMPLES ONLY.  REFER TO YOUR MONITOR'S
# USER MANUAL FOR THE CORRECT NUMBERS.

    
HorizSync   30-70

#    HorizSync    30-64         # multisync
#    HorizSync    31.5, 35.2    # multiple fixed sync frequencies
#    HorizSync    15-25, 30-50  # multiple ranges of sync frequencies

# VertRefresh is in Hz unless units are specified.
# VertRefresh may be a comma separated list of discrete values, or a

KDE is very slow when I resizing, moving windows. I think it's something in the config files cause RedHat at school with KDE and Gnome are working fast with same hardware.

one thing that may help a bit is kde/control centre/desktop/windows behaviour select 'moving' tab, and experiment with the settings there.
