One of the things that changes with each rev is the version of Xorg that is used on the
client. I've had the same experience, where clients that worked perfectly with version
3.x wouldn't work (at first) with version 4.x, and likewise with version 5. To fix it
usually involves setting a specific X server for that client in lts.conf. Often, it's
the vesa X server that works. So, in lts.conf, try changing
XSERVER = auto
XSERVER = vesa
or since you have Intel video chips, you might try
XSERVER = i810
LTSP defaults to 1024x768, but you can specify the resolution if you want, and this may
be necessary to get the res you want.
