Ubuntu 11.04 Nvidia - System hanging, now won't boot into X

I have had Natty running for a bit on my laptop (Clevo W150HRM, I7 with 8GB ram, Nvidia GT555m GPU).

Unsurprisingly I've had graphics issues but the biggest was that the machine would intermittently hang (2 or 3
times a day over 12 hours use), the only way of bringing it back to life was a hard powerdown and reboot.

I got fed up of it this morning and decided to try and change drivers (again). I went to the 'additional-drivers' GUI thingy and selected the only option it was showing offering 'experimental support for advanced 3d on Nvidia cards'. I then did a 'restart to finish upgrade' from the power menu once it had finished doing it's thing.

Now the machine will not boot into X, I get a glimpse of the ubuntu logo and the red/white dots, then a static black screen of misery.

When I try to boot into failsafe graphics it tells me Xorg.conf doesn't exist, throws a spazz and either hangs or dumps me into a command line login. HELP!!!! I have no idea what to do next!!!

I think you need to install the latest nvidia driver and kernel modules:

1. download the driver package from
1.5. my filename is:
2. put it on your machine somehow...
3. start ubuntu with the revovery mode option
4. select the root option in the menu and give root's password.
5. after the type 'init 3' and login again.
6. find the NVIDIA file and run it with: ./

this should install the drivers and kernel modules.

good luck

Thanks yoni, this is just me showing my cli ignorance but I cannot run the installer,
I get
bash: ./ Permission denied
How do I change the perm's via cli? I know the GUI way but thats not a big help now!!

I know it's something to do with chmod but have no further knowledge than that.

OK, so I google on how, used
chmod a=x
and permissions were right, then when I tried to run it again I got a message back I had the wrong arch!! I'm just going through the whole bit of adding the new x86-64 version to my stricken lappy with a usb stick and a xubuntu livecd!!

OK so I ran the installer, it grumbled about Nouvea being installed, offered a work around which involved re-starting and re-running the installer. Did that, installer ran and seemed to do lots of stuff, wrotea new xorg.conf and exited asking me to re-boot.

When I reboot, system still will not boot and failsafex still will not run and tells me
xinit: unable to run server "/usr/bin/X" no such file or directory
Use the --option , or make sure that "/usr/bin" is in your path and that "/usr/bin/X" is a program or a link to the right type of server for your display. Possible server names include:

Xorg     Common X server for most displays
Xvfb     Virtual frame buffer
Xfake    Kdrive-based virtual frame buffer
Xnest    X server nested in a window on another X server
Xephry   Kdrive based nested X server
Xvnc     X server accessed over vnc's RFB protocol
Xdmx     Distributed Multi-head X server
What do I do next??????

Looks like your Xorg got corrupted. try re-installing it (same steps as you did with nvidia drivers, just with the xorg application)
Seems like it should fix it. Good luck

Do you have nVidia Optimus with GT555M? If so you are doomed, like me.

Yep, GT555M plus I7 quad.

I have tried Bumblebee and Ironhide, neither seem to do anything, the Nvidia prop driver totally borks up everything so I'm stuck with nouveau driver and utterly shite fps.

I am hopeful that either Bumblebee or Ironhide will improve massively though as near enough all new lappys are shipping with optimus tech now.

I've got over the absence of xorg by re-installing, massive pita restoring everything from online backups though!!
