I have the same problem. Also making changes in xorg.conf and restarting lightdm hangs my laptop

I have a problem using a second monitor on it, with a mini-DisplayPort to DVI adapter. If I use only the LCD panel on the notebook, everything works fine. As soon as I connect a second monitor, it falls apart. The BIOS is set to "Discreet graphics", and any Optimus stuff is disabled, virtualization is disabled. First I tried with 12.04 LTS (64bit). Installation went smooth, no problems there. The only thing I noticed: by default it uses the nouveau driver which can't seem to recognize the graphics card correctly, at least I don't have the 1920x1080 resolution, only 800x600 or 1024x768 (see attached Xorg-12.04.1-nouveau.log). If I connect the second monitor using nouveau, nothing happens. I installed the proprietary driver offered after the first boot (version current-updates, 304.43-0ubuntu0.1) which did solve the resolution issue. It was working ok at 1920x1080 resolution. But the moment I connect the second monitor, it craps out. The LCD panel goes blank, the second monitor is in standby. I can login through SSH and see that Xorg is 100% CPU usage. I can also kill it but it doesn't solve the blank screen, only a reboot helps. Attached Xorg-12.04.1-nvidia_current.log file for when this happens. Last line is: [ 206.517] (II) NVIDIA(0): Setting mode "LVDS-0: nvidia-auto-select @1920x1080 +0+0, DP-0: nvidia-auto-select @1280x1024 +1920+0" [ 217.774] (EE) NVIDIA(GPU-0): WAIT: (E, 0, 0x917d) Also the mini-DP->DVI adapter gets really really hot if I leave it connected with blank screen for a couple of minutes. I've also tried the experimental drivers proposed on the Additional Hardware screen (304.48-0ubuntu0.1 and 310.14-0ubuntu0.1), same thing happens. I found a guide where somebody managed to run Ubuntu 12.04 with multiple monitors on this same notebook model: http://blog.pearce.org.nz/2012/08/enabling-external-monitor-on- lenovo.html I followed this guide and installed the nvidia driver provided by x -swat-ppa (304.64-0ubuntu1~precise~xup1). No luck. One monitor is just fine, but with a second monitor connected, Xorg is 100% CPU usage and nothing works. I've also tried booting with second monitor already connected, same thing, blank screen when lightdm supposed to appear. Only a reboot helps. With Ubuntu 12.10, the nouveau driver does recognize the card and the resolution with the LCD panel is OK. When I connect the second monitor, I can see the desktop, although with great discoloration and some flickering/blinking, but when I try to move the mouse over the whole screen just turns red and after that I cannot cross the mouse over to it anymore. Proprietary drivers behave the same way as on 12.04, blank screen + 100% CPU usage after connecting second monitor. I've tested the whole thing on Windows 7 it's working without problems, I can extend my desktop, I can move things to the second monitor etc., there is nothing wrong. Because of this, I don't think it's a hardware issue. Attached a bunch of logfiles and dmesg/lspci/etc output.
