compiz (core) - Fatal: No valid GL extensions string found.
... enable hardware DRI for your video card.

sorry .. can u tell in more detail .
I am new to Fedora. and I dont know how to set the DRI

easiest way, go to yast... "online Update"
update everything for a complete XML files
or before u do tat, uninstall ur 3D card driver 1st
then go to the repositories to redo the installation for the driver.

i am facing kinda same problem with u
it says my 3d card cannot run the 3d acceleration.
most probably due to hardware problem i think.
any body can enlighten me something?

i am using P4 2.4G 32-bit processor.
PX400 Phenix motherboard.
, obsolete Ati Radeon 9200 graphic card.
512mb kingston ddr ram

pango853 what's ur spec for ur pc? that would help.

Please help me. Thank you very much.

Did you read my post with the links? Install Compiz.

Pango853 12-24-2007 07:24 AM

To Glennzo :
Yes, I did, but notthing change . I still can start the desktop-effects.

Glennzo 12-24-2007 07:29 AM

Never mind Desktop Effects. Use ALT-F2 and type fusion-icon. See what that gets you and go from there.

Pango853 12-24-2007 07:47 AM

i type fusion-icon : it show like
* Detected Session: unknown
* Searching for installed applications...
* No GLX_EXT_texture_from_pixmap with direct rendering context
... nor with indirect rendering, this isn't going to work!
....
..

What is the problem ?

And I used the way the install my x1950 card.
http://forums.fedoraforum.org/showth...3&page=1&pp=10
then follow http://forums.fedoraforum.org/forum/...ghlight=compiz
to install the compiz and so on.
But, in fact, I just wanna try the Desktop-Effects in Fedora. Is that so difficult?
I can use it when I use Ubuntu before. The same hardware. But I just like Fedora more. Can anyone help me.

* thx Glennzo, you did help a lot.
