I'm having trouble with an Acer R11 laptop (client). It boots over Lan getting its disk image from an 14.04 LTSP Server. After the initial Acer Splash-DHCP-TFTP sequence a console is shortly visible, followed by the Acer Splash (probably still in video memory) and then the screen turns black with backlight on.
The LTSP 14.04 install is tested and works with an Asus Eee T101MT (including Touchscreen). Important to know the same Acer R11: Live USB 14.04 works fine (with Touchscreen), and LTSP 12.04 as a client also works (but without Touchscreen).
I am desperately trying to solve this. I tried kernel parameters (nomodeset, noapic...)
I can reach the client over ssh.

I can even startx over ssh and then start an xterm on the server.
When I try to get a working xorg.conf with Xorg -configure
the error I get is Number of created screens does not match number of detected devices.
