maxgravitt Posted July 21, 2004 Report Share Posted July 21, 2004 Hi, I get errors when running several games under Linux. I can run many of the simple games such as Frozen Bubble and LBreakOut, but I want to run some of the more 3d ones. Here is the problem I am getting (most recently, when running "BZFlag"). Xlib: extension "GLX" missing on display ":0.0" Any ideas? thanks, Max Quote Link to comment Share on other sites More sharing options...
ac_dispatcher Posted July 22, 2004 Report Share Posted July 22, 2004 Seems you may not have direct rendering on. open a konsole and type - glxinfo | grep direct here is what I get: acdispatcher@arora acdispatcher $ glxinfo | grep direct disabling TCL support direct rendering: Yes Here is the standard series of questions: What kind off computer (specs) What kind of Video card Have you installed drivers yet Quote Link to comment Share on other sites More sharing options...
Qchem Posted July 22, 2004 Report Share Posted July 22, 2004 Another question, what distro? Quote Link to comment Share on other sites More sharing options...
maxgravitt Posted July 22, 2004 Author Report Share Posted July 22, 2004 I am using Mandrake 10, and I have not installed any drivers manually other than whatever was installed during installation of the OS. When I open up the Mandrake Control Center, it correctly identifies my card as a "NV17 GeForce4 MX 420". Do I need to install some other driver or something else? thanks!

maxgravitt Posted July 22, 2004 Author Report Share Posted July 22, 2004 When I type "glxinfo | grep direct", I get the following errors (same as the original). [root@user-0ce2i57 games]# glxinfo | grep direct Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0". Xlib: extension "GLX" missing on display ":0.0".

phunni Posted July 23, 2004 Report Share Posted July 23, 2004 You don;t have direct rendering - do a search on the board for your video card for some hints as to how to proceed from here. Quote Link to comment Share on other sites More sharing options...
Qchem Posted July 23, 2004 Report Share Posted July 23, 2004 You need the binary nvidia drivers, like phunni mentioned search this forum for how to install them - or bite the bullet, jump over to nvidia.com and follow their instructions!

maxgravitt Posted July 25, 2004 Author Report Share Posted July 25, 2004 After I installed the NVIDIA driver from nvidia.com, it worked great. Thanks!! Quote Link to comment Share on other sites More sharing options...
Guest like_gobeawan Posted August 18, 2004 Report Share Posted August 18, 2004 Hi all, I have similar error message like the above, but then it's because i'm trying to render a visualization scene from remote machine to my local PC, while i'm connected to it by telnet GUI application (XManager). Apparently, the remote machine can't perform direct rendering to the local PC. Is there any way to get work around this? Thanks for any help in advance! Like.

phunni Posted August 18, 2004 Report Share Posted August 18, 2004 I would have thought it was the local PC that would have to worry about the work of direct rendering... Perhaps your remote machine is haveing trouble properly exporting the display? Can you give more details on the exact error you are getting?

illogic-al Posted August 18, 2004 Report Share Posted August 18, 2004 yeah the remote machine shouldn't have to do anything but display. Support needs to be on the local end for this too work (basically agreeing with what phunni said) Quote Link to comment Share on other sites More sharing options...
Guest jpcohen Posted September 2, 2004 Report Share Posted September 2, 2004 Hi all i have this problem too: Xlib: extension "GLX" missing on display ":0.0". Error: couldn't find RGB GLX visual But i already installed the nvidia drivers. And driver module, in XF86Config-4 is nvidia. Quote Link to comment Share on other sites More sharing options...
devries Posted September 2, 2004 Report Share Posted September 2, 2004 (edited) What drivers did you install and how did you install them (rpm or nvidia installer)? Seems to me something went wrong during the install. Try uninstall and install again. If you're not sure about the install procedure look in the FAQs of this forum. Good luck <edit>sorry forgot something In the Module section (of the XF86Config-4) , make sure you have: Load "glx" You should also remove the following lines: Load "dri" Load "GLcore" From the nvidia readme. Good luck again Edited September 2, 2004 by devries Quote Link to comment Share on other sites More sharing options...
Guest jpcohen Posted September 2, 2004 Report Share Posted September 2, 2004 In the Module section (of the XF86Config-4) , make sure you have: Load "glx" I played with the XF86File and i forgot to retype Load glx.... Anyway, Just one quick question, i can't seem to be able to install the last 2 nvidia drivers (ps; i always install from sources). They don't built and exit with "unalble to buid driver, chech nvidia-installer.log for more details", and this is the line i read from the log... Has anybody ever experienced this or something like that ?? :unsure: Quote Link to comment Share on other sites More sharing options...
devries Posted September 2, 2004 Report Share Posted September 2, 2004 What kernel are you using? Are the correct kernel-sources installed? Does --update (nvidia-installer --update) work? Have you tried removing the installed driver (nvidia-installer --uninstall) before you tried to install the new driver? Uh.. I guess that was it. :) Good luck Quote Link to comment Share on other sites More sharing options...
