At present I am using a lower resolution external display (becaue I am on an extended trip and it's what I have) in "Extend these displays" mode with my hi-res laptop display. This seems to confuse X (and also xlaunch?). Here are the issues: When booted with the external lo-res display as the main display: - xterm windows come up with a very large font. - The X menu (controlled by .XWinrc) does not come up. If I then change to have the laptop hi-res display as the main display, without rebooting, and without restarting X - The xterms still have a big font (I did not restart them, so no surprise) - The X menu works (over on the laptop screen). I then restart X, - The new xterms still have the large font - The X menu still works If I then shutdown X, make the external lo-res display the main display, and restart X, - The xterm fonts are big - The X menu does not come up. Then, if I set the laptop to be the main display, reboot Windows, and restart X, - The xterm windows have the right size font (but start on the laptop and need to be dragged over to the other display; they do resize appropriately there) - The X menu works (but is way over on the laptop display). Finally, if I change to have the external display to be the main one, without restarting X, - New xterms come up with the right size fonts - The X menu comes up on the external screen (as desired) If I shut down X and restart it (external display still main), - xterm fonts have the right size - The X menu does not come up. It seems that, at the least, I need to *start* X when the laptop (hi-res) display is main. I'm less clear as to whether I need to *boot* with it main (I can try that later). Is there an explanation for this? Should I be doing something differently? Is there a bug? Thanks for any insight you can offer! Eliot Moss Here are further details of my setup: I use xlaunch to get my X windows going.
