Some intel chipsets can get confused about outputs and think, for example, that an LVDS output is present when it isn't. This causes the driver to choose the wrong mode for the display.
Could you do the following: 1. Remove the X_CONF line 2. Boot the thin client and log in. 3. Run "xrandr" from a terminal window in the logged in session, redirect to a file, and paste here. 4. Tell us whether you connect to the monitor with DVI or VGA or through some adapter or KVM switch. 5. From the logged-in session, run: "ltsp-localapps xterm" to bring up a local xterm. Then, copy the client's Xorg log file to your home directory and paste it here, as well. (In the local xterm, cp /var/log/Xorg.7.log ~/) Between the xrandr info, the Xorg log, and how you connect to the monitor, we should be able to sort out what is going on. If I had to guess right now, we would simply need a directive to turn off an extraneous interfering output in the driver. -Gadi On Fri, Dec 10, 2010 at 1:44 AM, Philip Loewen <[email protected]> wrote: > LTSP is really super.
