Hi,
thanks for reporting this.

Please attach your complete /var/log/Xorg.0.log and /var/log/syslog files to this bug report after the bug has been reproduced.
Also, please post the output from the following command:
* lshw -C display

Thanks in advance.

i can't do it, because as i said, my system freezes, and it doesn't let me do to anything else!

I have this same problem. Video card is Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device (rev 03) Subsystem:Micro-Star International Co., Ltd. Device 5778

here is the output from lshw -C display:

Thanx Everett Attebury, i just couldn't do it, because of the reasons that i explained before!

Thanks for uploading those files Everett.

The Xorg thing is the most relevant part here, so we should gather more information. Could both of you try to get a backtrace from our lovely x-server by following the instructions at https://wiki.ubuntu.com/X/Debugging and attach to this bug?

@ manzur: Perhaps you could tail the xorg log by running this i a terminal and then reproduce the bug?
* tail -f /var/log/Xorg.0.log >> ~/296833_tail-of-xorg.log

It should create the file 296833_tail-of-xorg.log in your home directory and hopefully fill it with relevant information.

I had a similar problem with my i845 card. I saw a post in Fedora Forums that I thought addressed it and tried the fix. It worked for me. Here's my edited xorg.conf file:

Section "Device"
 Identifier "Configured Video Device"
 Driver "intel"
 Option "AccelMethod" "XAA"
EndSection

Section "Monitor"
 Identifier "Configured Monitor"
EndSection

Section "Screen"
 Identifier "Default Screen"
 Monitor "Configured Monitor"
 Device "Configured Video Device"
EndSection

Hope this is helpful.

I got some info from here:

Many users are having the same issue.
Compiz have a blacklist file to report problematic video cards, and make compiz don't be used in this cards.
http://wiki.compiz-fusion.org/Hardware/Blacklist

In this case, maybe there are some problems with Intel driver, so.. Compiz guys disable use of Compiz to avoid possible problems.

You can disable this blacklist writing in a console (Terminal):

mkdir -p ~/.config/compiz/ && echo SKIP_CHECKS=yes >> ~/.config/compiz/compiz-manager

But, please, if you use this command, don't report bugs of weird behavior playing movies, gamming, etc. You maybe will experiment problems.

Could you please also run `lspci -vvnn > lspci-vvnn.txt` and attach that file to this bug report? Thanks ahead of time.
