Hello everbody:
I use Fedora 10 i386 in a Compaq Presario Notebook C735EM. The system is updated, and my desktop is gnome with compiz fusion enabled. The graphics card is intel. The problem I have is that when I change the current user session to another user, the system freezes, crashes. All I can do is move the mouse. I can not close the X. I can not move to terminal Cntr + Alt + F1 I tried to do before turning off compiz fusion, but also freezes. In a virtual machine that I can not, so I guess it is problem of my laptop. Can someone help me?
Sorry for my english. I´m spanish.

I am not sure that there is a current bugzilla on this one (I haven't had time to look into it), but I have this issue as well. I'm working around it by using the following /etc/X11/xorg.conf:
---8<---- Cut Here ---
Section "ServerLayout" Identifier "Default Layout" Screen 0 "Screen0" 0 0 InputDevice "Keyboard0" "CoreKeyboard" EndSection
Section "InputDevice" # keyboard added by rhpxl Identifier "Keyboard0" Driver "kbd" Option "XkbModel" "pc105" Option "XkbLayout" "us" EndSection
Section "Device" Identifier "Videocard0" Driver "intel" Option "NoAccel" "True" Option "DRI" "True" Option "DDC" "True" Option "XVideo" "True" Option "DevicePresence" "True" Option "ShadowFB" "True" Option "DisplayInfo" "True" EndSection
Section "Screen" Identifier "Screen0" Device "Videocard0" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 EndSubSection EndSection
---8<---- Cut Here ---
The key thing is the following line in the Device section:
Option "NoAccel" "True"
This disables the hardware acceleration on the video card. Not great, but it stops the hangs.
Woogie

I think there's a bugzilla for this. I saw a post about it here and looked at a bugzilla about a week or so ago that sounds like this. I think someone had suggested the "NoAccel" workaround in that report. I didn't keep the link though, sorry.
I think the post about this issue was probably no more than two or three weeks ago, so check the archives because I think that post has a link to the bugzilla.

I had a similar hang up of the video display when switching between users, once. intel graphics here (GMA 4500HD) on a Dell Latitude E6500. Meanwhile, I disabled compiz 'cause it was freezing my display when putting screen to standby and other situations. I'm not sure if it was related anyway, I didn't try to reproduce it, neither tried to disable acceleration as you did.
One thing I noticed w/ the different kind of display freezes I had, is that the laptop was not freezed, I could login by ssh remotely and reboot the system.
Regards,

I can confirm this was not related to compiz, as I'm nearly freezing 100% of the times I do switch between users again. Up-to-date F10, Intel GMA 4500HD inside this Dell E6500 Latitude.
