My latest build is LFS-SVN-20120623. When I loaded x-7.7-1 on top I found that 
the latest nvidia proprietary driver, 295.59, locked up the GPU. May be the 
optimizations are incompatible with the latest xorg-server - who knows?

I thought I'd try the nouveau driver in the BLFS book so I compiled the drm 
nouveau modules into the kernel. When I booted the laptop, the screen went 
blank and then cycled through red, green, blue and white - continuously. I 
could only do Alt+sysRQ+b to reboot it. Everything else was dead. As a last 
resort I went to http://nouveau.freedesktop.org/wiki/InstallDRM and did an 
out-of-the-tree build of the modules to see if the latest versions were any 
different. I got the same result.

I read that the graphics card can do this if it does not receive any signal. 
Other than that, I have no idea why this happens.

Any suggestions would be welcome - apart from trashing the laptop or the 
graphics card.

Thanks

jb.
