Missing GLX Extention
 

I chose Atlantis as a screen saver in GNOME, then I tryed to preview Atlantis, I got a black screen and it says that I'm missing the GLX extention that the screen saver needs to run.

Anybody know anything about this? I'd just fix it , but I'm too much of a newbie to even figure out where to start on this one...

What sort of graphic card do you have?

S3 Virge, And I Assure you it is nothing special.
Is that what is holding it back ? Right now I'm just testing Everything I can on Slackware, before this machine becomes one of my DNS Servers.

So if this is the case I'll try it on my other machine with a VooDoo card that has 32mb memory once I get that one changed over.

Are you loading the glx module in your XF86Config file?

Check for:

Section "Module"
.
.
.
Load "glx"
.
.
.
EndSection

in your /etc/X11/XF86Config file.

You can also check your /var/log/XF86Config.0.log log file and see whether you are loading glx. You should see something like:
.
.
.
(II) LoadModule: "glx"
(II) Loading /usr/X11R6/lib/modules/extensions/libglx.so
.
.
.

I Looked in /etc/X11/XF86Config file and it says:

#This loads the GLX module
# Load "glx"

EndSection

then I looked into /var/log/XF86Config.0.log
and there is no XF86Config.o.log
there are only 3- directories in /var/log/
XFree86.o.log
XFree86.8.log
apache/

XFree86.o.log is the one you want, post any error messages from the end of that for us to look at.

I logged on as root and I get access denied, let me try to get to it via GUI

no mention of it in "XFree86.o.log"
but has it in "XFree86.8.log"

and I don't see any obvious error messages.

What would the error messages look like for example?

If you notice from above (and if you INDEED have it written like that in your XF86Config), you are NOT loading the glx module because it is commented out. :eek: You may want to uncomment the glx loading line (by removing the # from the line), and try running XFree86 again.

Ahhh Haa
Thanks, will try right away...

I'M trying vi /etc/X11/XF86Config
and it opens the file, but why can't I edit?

are you root? before you edit it you need to become the super user by typeing 'su' and then the root password. if its not that then read the following.

vi can be a bugger to use. You have to get your head around the fact that it has two distinct modes. One is the command mode where you type stuff into a prompt and it will do stuff (to get to the prompt press the escape key a number of times until the computer beeps at you then enter a colon and you should see one at the bottom of the screen). The other is the insertion mode. press either the insert key on your keyboard or 'i'. this will allow you to type.

btw when you press backspace the cursor will nip back but it keeps the character in place. It will look like it hasn't worked. Just press escape and the offending character will be replaced (or just leave it and the character will not be kept when you save).

After making the changes go into command mode and type 'wq' and it should save it all and drop you back to the command line. You'll need to be root to make these changes since XF86Config is a configuration file in /etc which is all owned by root.

I personally would use an easier text editor (try emacs, pico or nano) since vi is a bit of a bugger to use when you start out.

Hey, Thanks for the help guys, I could only make heads and tails with the
Vi IMproved editor, now it just says that Atlantis does not support the glx extention, so the heck with it, I've got this baby up and running on DSL right now and have a name & Web server to figure out...

Thanks again...

on vim, you can just use the arrows to move around, erase the "#" by hitting x on the keyboard, then hit ctrl-ZZ to save and exit.
