[i945gme] After pressing Switch the user and switch back to the same user, the screen becomes black

[Shaform]

Binary package hint: xorg

1.Press Switch from XXX
2.Goes to the gdm, and login with the same user XXX
3.The screen becomes black

But I believe the desktop is still here, its just that the screen is black,
because if I press power off button on my netbook and press Down & Enter, it would reboot the computer.

Could you please try disabling Desktop Effects (Compiz) through System->Preferences->Appearance->Visual Effects (Tab), reboot, and see if the problem still exists?

After reproducing the issue, can you switch to a TTY with Ctrl+Alt+F1, login, and run
cat /var/log/dmesg > dmesg.txt
cat /var/log/Xorg.0.log > Xorg.0.log.txt
Then see if you can switch back to the original session with Ctrl+Alt+F7. What screen does this give you? (If it's still black, switch back to Ctrl+Alt+F1 and run "sudo reboot" to reboot".) Then upload the two .txt files you created in your home directory when you answer the above questions.

Well, I cannot reproduce the problem now...
I don't know what fixed the problem...
