gdm_slave_xioerror_handler: Fatal X error

Problem: attempt to login to Gnome fails as you cannot input any keyboard stokes into the user id window.

When I researched the Net, I found two threads with a similar problem statement and neither thread showed the resolution. One thread went for a couple of replies but no resolution and the other didn't even get a reply. I would like the next poor soul with this problem to be able to find a thread with a resolution attached to it. So you won't have to look up earlier parts of this thread, here's the original problem statement:

The problem can't be fixed by restarting Gnome.

Unfortunately, I have pretty much reached the limits of my  troubleshooting abilities. Surely, there's some kind soul out there who  can help me resolve this problem. Any assistance will be sincerely  appreciated.

I am having the same problem...

Well I guess this X crash started to happen since I installed last update (kernel includes) But I really don't remember which things it installed, any ideas of a way to know exactly?

Thank you all!

bojo42: I think the message 'WARNING: gdm_slave_xioerror_handler: Fatal X error - Restarting :0' is just a generic message saying that something has caused X to crash, and could be caused by anything. The backtrace in my GDM log indicates that my crash is caused by a different problem to the bug report you refer to.

I still get this quite frequently, but it only ever seems to be when 2 users are logged in. I'm attaching my GDM log, which contains a backtrace from the crash (something I should have done when I opened the bug report). The backtrace always seems to look the same after each crash.

I suspect the 'Unix font server' is down or something that X cant read fonts from the default path.

comment out the default FontPath
then add

 

Code:
    FontPath   "/usr/X11R6/lib/X11/fonts/local/"
    FontPath   "/usr/X11R6/lib/X11/fonts/misc/"
    FontPath   "/usr/X11R6/lib/X11/fonts/75dpi/:unscaled"
    FontPath   "/usr/X11R6/lib/X11/fonts/100dpi/:unscaled"
    FontPath   "/usr/X11R6/lib/X11/fonts/Type1/"
    FontPath   "/usr/X11R6/lib/X11/fonts/Speedo/"
    FontPath   "/usr/X11R6/lib/X11/fonts/75dpi/"
    FontPath   "/usr/X11R6/lib/X11/fonts/100dpi/"
into /etc/X11/config

and the problem will be sorted out.

Cheers,
Frankie

p.s. I typed this here just to let ppl to search if they haf a similar problem. nonetheless, it'd be great if someone can explain why X defaults the FontPath "unix/:7000"?
