From Bugzilla Helper: User-Agent: Mozilla/5.0 Galeon/1.2.0 (X11; Linux i686; U;) Gecko/20020408 Description of problem: Upon resizing certain windows (occasionally xdvi, and most frequently Adobe Acrobat), the screen completely hangs with the exception that the mouse pointer can still move. No interaction with the screen is possible, and the keyboard is unresponsive. Upon ssh'ing remotely into the machine X appears to by taking up 99.5% CPU usage. kill -9 as root succeeds in restarting gdm and keyboard allows me to log back in locally. Resizing gets as far as the window dimensions appearing on the screen before it hangs. Version-Release number of selected component (if applicable): How reproducible: Sometimes Steps to Reproduce: 1. Start X (I use gbm on startup to log in) 2. Run Adobe Acrobat and load a pdf 3. Drag bottom-right corner of window outwards. Actual Results: Window dimensions appear, and screen promptly hangs as described above. Expected Results: Window should have resized and allowed continued operation. Additional info:
I have since had the same problem when resizing gv (ghostview) window, and immediately upon starting ggv (GNOME version of gv).
Attach X log and config individually using link below.

In producing the logfile I found that acrobat does not always make X hang. I needed to have Galeon running at the same time - I haven't noticed this before since Galeon is normally always running.
The condition seems to occur for a wide range of applications. I have had the same problem with the following: Importing data into Gnumeric Changing preferences in Galeon Looking up a word in GDict Changing desktop properties on Gnome Desktop The above seem to indicate that the problem is linked to GNOME or Gtk.I do not recall having any such problems with Redhat 7.2.
Despite efforts to work around this problem, my machine is too unstable at present. Is there any way in which I can provide information that will bring about a swifter resolution? Perhaps I can run a debugging utility on X? I'd appreciate any suggestions.
The same happens with my system too. I had rh7.0 and had the problem relatively rare (2-3 times a week) and installed rh8 because I thought it will solve the problem, now I have two restart X 2-3 times a day! I found that the hang happens when I'm trying to resize, move or scroll a window. I'll attach my log and config files.

I found that you don't get crashes if you disable the dri module in XF86 config file (put a # before load "dri"). That's all I can suggest, I'm afraid.
I also disabled dri one week ago and it seems to be stable for me too. Thanks for the idea.
My apologies for not responding sooner. There are so many XFree86 bug reports, it's easy to get lost in them sometimes. It sounds to me like there is a 2D acceleration glitch of some kind going on. You've stated disabling DRI solves the problem. Can you re-enable DRI, and use Option "noaccel" in the device section of the X config file instead? If that also works around the problem, we can further refine it down to the offending problem. Another thing that would greatly help me, would be if anyone who encounters this problem could test out Red Hat Linux 8.0 and see if it also has this problem. I've also got RPM's of XFree86 4.2.1 on ftp://people.redhat.com for 8.0 in my testing directory which will be released as erratum in the near future. If someone could test those, that would be useful. If none of these solve the problem, for the really really brave, I've got XFree86 CVS RPM's also on people.r.c in the live-grenades directory for testing. Any feedback that anyone can provide on any/all of the above suggestions would be very useful. I will be releasing 7.3 erratum soon, so if I can gather info to fix this problem for you, I'd like to make sure it is fixed. Thanks
I reenabled dri, and wrote Option "noaccel" into the r128 driver section. By the way I'm using Redhat 8.0. One reason for the update was this bug, but it didn't disappear unfortunately. I'll attach my xf86config-4 too.

Just an update... I've just upgraded my machine to RH 8.0, and applied all updates. I suffered a similar crash (using gphoto) as before. I have now downloaded the suggested updates from ftp://people.redhat.com/mharris/testing/8.0/XFree86/4.2.1-10.5/i386/ and will give these a go. Fingers crossed they do the trick.
Assuming the new X packages did the trick in comment #16 above, and closing bug as CURRENTRELEASE. If the problem recurs, please upgrade to Fedora Core 2 or Red Hat Enterprise Linux 3, and update each to the latest erratum to test if these new OS releases resolve the issue. If the problem persists, please reopen the report with updated information, config/log files, etc. Thanks.
