[How to fix] Dual Monitor Freeze in Ubuntu 12.04 64bit



one of the features that ubuntu 12.04 promised was better support for dual-monitor however after I upgraded from ubuntu 11.10  to ubuntu 12.04 I noticed if I change the display settings it will freeze for example I noticed:

- I  move the external monitor to the left of laptop monitor , (or above it) it freezes
- I try to turn of the laptop monitor ,so I only have my external monitor it will freeze again. the mouse and keyboard stop responding and the only way key that respond is
 ALT+PRINTSCREEN+K (to restart the X server)

I openned a bug in Launchpad and I tried every possible solution  after pulling my hair and not sleeping in the whole night .Here is how I fixed it : To fix dual monitor freeze in ubuntu 12.04 you need to install the older version of  xserver-xorg-input-evdev

1- Download the following two packages to your desktop:
xserver-xorg-input-evdev-udeb_2.6.99.901-1ubuntu3~lp921236_amd64.udeb (24.0 KiB)
xserver-xorg-input-evdev_2.6.99.901-1ubuntu3~lp921236_amd64.deb (38.0 KiB)
2- Open a terminal
cd Desktop
sudo dpkg -i *.deb
3- Restart your computer or if you are lazy just restart the X Server (ALT+PRINTSCREEN +K)

Very thank you!! You don't solved my problem directly but indirectly.

I just was a problem switching videomodes. My video freezed when I doing that. Changing a game from window to full screen, using nvidia-settings to set a video mode (Apply button) and so, freezed my video and Xorg 100% cpu usage.

The solution was installing your xorg-input-evdev package.

And of course installing NVIDIA manually 295.59, certified for my GeForce GT 440.

It just taked me near 2 hours to solve this problem.

I asked in askubuntu.com but they just closed my question!! Very bad for my first impression in askubuntu. I will never ask anything there.

Hey
I did what it said and restarted my computer but i dont think it works also it doesnt recognize the keyboard and the usb mouse anymore. its a laptop so i can only use the touchpad which it does recognize for some reason thankfully.

How can i reverse it ? I tried updating ubuntu but it gives me an error like the package is broken or something. help!
