 No, it doesn't. Perhaps I need to reinstall the Nvidia driver.
 but it's weird that everything seems to just work except for FF 16.0.1.

 Confirmed.

 FF 16.0.1 from the mozilla site crashes X on CentOS 5.8 32-bit and
 64-bit if the latest NVIDIA drivers are installed (304.51).  If the
 older drivers (295.71) are used, it seems to be OK.  It's also OK if
 the NVIDIA drivers are not used.  Also seems to be OK on CentOS 6.3.
 I haven't tried older revisions of the 304 series driver.

 but I'm using 290.10, and have been for a few months. it just now
 started doing this. very strange.

 So, I reinstalled the same Nvidia driver (290.10) and now FF 16.0.1
 works! Go figure. I guess some file may have gotten hosed, somehow.


 The reason is that the NVIDIA installer overwrites some distro files
 with it's own version of some libs, in this case the offending file is
 /usr/lib{64}/xorg/modules/extensions/libglx.so

 So you install the nvidia drivers and everything works just fine, for
 months.

 Then last week an update was released for xorg-x11-server-Xorg which in
 turn re-overwrites the nvidia lib with the distro lib and you see the
 error you reported earlier along with the symptoms you describe.

 Then you reinstalled the nvidia drivers which of course over wrote the
 newly updated distro version of libglx.so (again) and everything was
 back working as before.

 that all makes perfect sense, except,... why did everything ELSE
 still work? (I admit to not having tried any of the GL screensaver
 demos, or any high-end GL games...)


Only applications using OpenGL would be affected.

If you want to test for yourself, try running 'glxgears'.

GoogleEarth is another good test case, as it stresses the driver pretty hard.

yup, it sure does. However I didn't think of it being only a GL problem
until afterr I had already reinstalled Nvidia stuff. but I imagine it's
pretty likely that any of those proggies would have tripped over the
same problem.

At around the same time I got a notice from mdadm that my raid array
had thrown out one of the pair of drives, so I suppose it's possible
that the drives were out of sync when that happened. doesn't seem too
likely, though, since that Nvidia driver has been in place for several
months.

neverthelss, FF is now working (and I just ordered a new drive from
newegg to fix up the RAID array) :( :(

The solution is not to use the NVIDIA provided binary drivers but 
instead to use the same drivers properly packaged by elrepo for your 
distro. The elrepo rpm package installs these libs to a separate 
directory where they will not conflict with the original distro libs and 
you will void this type of mess. Not to mention you don't need to 
reinstall the drivers every time there is a new kernel update.

OK, that makes sense.  Further testing showed the problem here to
be dependent on whether the machine was rebooted and the new NVIDIA
drivers installed before or after xorg-x11-server-Xorg was installed.

 instead to use the same drivers properly packaged by elrepo for your

  No, it doesn't. Perhaps I need to reinstall the Nvidia driver.

  Confirmed.
 
  FF 16.0.1 from the mozilla site crashes X on CentOS 5.8 32-bit and
  64-bit if the latest NVIDIA drivers are installed (304.51).  If the
  older drivers (295.71) are used, it seems to be OK.  It's also OK if
  the NVIDIA drivers are not used.  Also seems to be OK on CentOS 6.3.
  I haven't tried older revisions of the 304 series driver.
 
  but I'm using 290.10, and have been for a few months. it just now
  started doing this. very strange.
 
  So, I reinstalled the same Nvidia driver (290.10) and now FF 16.0.1
  works! Go figure. I guess some file may have gotten hosed, somehow.
 
 
 The reason is that the NVIDIA installer overwrites some distro files 
 with it's own version of some libs, in this case the offending file is 
 /usr/lib{64}/xorg/modules/extensions/libglx.so
 
 So you install the nvidia drivers and everything works just fine, for 
 months.
 
 Then last week an update was released for xorg-x11-server-Xorg which in 
 turn re-overwrites the nvidia lib with the distro lib and you see the 
 error you reported earlier along with the symptoms you describe.
 
 Then you reinstalled the nvidia drivers which of course over wrote the 
 newly updated distro version of libglx.so (again) and everything was 
 back working as before.

that all makes perfect sense, except,... why did everything ELSE
still work? (I admit to not having tried any of the GL screensaver
demos, or any high-end GL games...)

 
 The solution is not to use the NVIDIA provided binary drivers but 
 instead to use the same drivers properly packaged by elrepo for your 
 distro. The elrepo rpm package installs these libs to a separate 
 directory where they will not conflict with the original distro libs and 
 you will void this type of mess. Not to mention you don't need to 
 reinstall the drivers every time there is a new kernel update.

I'm sure this is a good idea. but I've been doing it this way for
soo long that I tend to not think of it until I've already done
it the old-fashioned way. (we get set in our ways when we get old! :) )

Re: [CentOS] Centos 5.8: starting firefox-16.0.1 kills X [updated]

 This just started happening this evening.
 
 a little history:
 way back last year, or thereabouts, I posted about a weird problem I was
 having. over the course of 2 or 3 days I figured out how to fix it, but
 not what the cause was. the fix amounts to navigating to my user's 
 .local/share/mime directory and removing the file named globs.
 
 So, back in the present: this evening that same problem recurred for
 the 3rd or 4th time since the original event mentioned above. so I
 deleted that file, logged off and back on (without the log off/on, the
 problem still occurs).
 
 Having done that, I went to fire up firefox and KABOOM!!
 X dies and I land back at a login prompt. 
 several times. 
 every time.
 tried running firefox from a terminal but I don't see anything
 echoed to the terminal before it is blown away.
 
 I still have the tarball from mozilla.org, so I moved aside the directory
 where the firefox runtime stuff is, re-extracted the tarball and it still
 croaks in the same way.

Trying to start firefox in safemode makes no difference. still
instant death.

 
 I'd appreciate some ideas to try, if anyone has any. Thanks in advance!
 
 In the meantime, Opera works (though I can't install 12.0.2 for lack
 of a suitable version of rpmlib, so I'm not left browseerless.
