Enable DRI

Hi Guys,

I am trying to configure Direct Rendering on my PC, whatever i try i get direct renedering as "No".

I have RHEL 4, and this is what is available in my /etc/X11/xorg.conf file

"

# RgbPath is the location of the RGB database. Note, this is the name of the
# file minus the extension (like ".txt" or ".db"). There is normally
# no need to change the default.
# Multiple FontPath entries are allowed (they are concatenated together)
# By default, Red Hat 6.0 and later now use a font server independent of
# the X server to render fonts.

# Specify which keyboard LEDs can be user-controlled (eg, with xset(1))
# Option "Xleds" "1 2 3"
# To disable the XKEYBOARD extension, uncomment XkbDisable.
# Option "XkbDisable"
# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults). For example, for a non-U.S.
# keyboard, you will probably want to use:
# Option "XkbModel" "pc102"
# If you have a US Microsoft Natural keyboard, you can use:
# Option "XkbModel" "microsoft"

# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
# Option "XkbLayout" "de"
# or:
# Option "XkbLayout" "de"
# Option "XkbVariant" "nodeadkeys"
#
# If you'd like to switch the positions of your capslock and

I also have GL libraries in "/usr/X11R6/lib" folder.

What do i need to do to get it enabled? Can you guys help me out

jdkaye · 07-31-2009, 04:07 AM

You'll never get direct rendering with a vesa driver. What is your graphics card and why aren't you using the driver that's appropriate for it? That would solve your problem I think.
cheers,
jdk

giri8 · 07-31-2009, 04:26 AM

I dont know how to configure the driver for my card,
can you please suggest me to get it configured.

If i run "lspci "
i get the following output :
00:02.0 VGA compatible controller: Intel Corporation: Unknown device 2972 (rev 02)

jdkaye · 07-31-2009, 04:45 AM

Have a look at the output of

Code:

lshw

Your system may want you to run that as root.
Do you know, for a fact, that your graphics card even supports 3D accleration? Is it a laptop? What make and model? Your really not providing much info here.
I would guess you need the i915, the i810 or the i830 driver but can't be sure until we know more about which card.
cheers,
jdk

giri8 · 07-31-2009, 04:53 AM

Sorry for not giving much informtion,

I am using a Desktop PC, its having Redhat Enterprise linux 4, 1GB RAM and Dual core processor.

When i ran lshw
i get following error:
bash: lshw: command not found

I am running it as root user.

The problem is lspci says unknown device and my driver is
generic vesa driver, as per xorg.conf file.

Can you help me out to resolve this and
get a proper driver for my card ?

jdkaye · 07-31-2009, 06:22 AM

Telling me that you have a Desktop PC is not very helpful. Did your computer come with specs? Does it have a brand name? I really can't help you at all with so little information. You really need to find out what graphics card you're using. Can you install the lshw package for RHEL?
jdk

giri8 · 07-31-2009, 08:53 AM

Sure i shall install lshw and get back to u.

This is the output from lshw:

I think you need to go back to the basics and learn a little more about computers. Proc (p4 with hyperthreading, not a dual core), chipset, video card, etc is what most people know months before they even buy it. Or if you happen to get a computer on the fly, working on something that isn't yours, that is the first thing you do.

82946GZ/GL Integrated Graphics Controller

There's the info you need. You will find plenty of tutorials on google for getting DRI to work with onboard intel video. But asking a forum how to get hardware acceleration to work on your video card, but don't know what kind of video card you have is crazy. It's like calling a mechanic and telling him you have a black car with 2 doors that isn't working.

jdkaye · 07-31-2009, 10:06 AM

I agree with wr3ck3d entirely. lshw has identified your graphics card as the Intel one he mentions in the previous post. Please note it down somewhere and don't forget it.
Have a look here:

Thanks jdk, for the reply ...

wr3ck3d my friend, thanks for your suggestion, everyone has a starting point, i was a Windows user and new to Linux, you cant ask a baby to swim the day its out :-)
