I do this to set up the external video: xrandr --output VGA --above LVDS That's to span a single desktop over both monitors. Some desktop environments have their own ideas about which monitors are attached and what part of the desktop is shown, and that must be changed in the DE's settings. My use case involves putting everything on one monitor at a time -- the larger desktop LCD when it's plugged in, and the laptop display when the external monitor is *not* plugged in. From the sound of the request, that is the use case the orignial querent in this thread had in mind as well. Your tip could well be useful for some use cases, though. -- Chad Perrin [ original content licensed OWL: http://owl.apotheon.org ] ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
Attaching a monitor via vga
I have a thinkpad t61p running freebsd9.0. The window size is 1680x1050 -- a reasonable size -- but the screen itself is 38cm. (15) which is irritatingly small for my old eyes. So I want to attach an external monitor via a vga cable, which I have been doing with my RedHat thinkpad A31P for years. I tried attaching Asus VE228H (1920x1080) but it would display only part of the window (the top-left corner). I get a similar behaviour with a Samsung SyncMaster. When I tried to xinit with the monitor attached, it displays an even smaller part of the screen. (On my previous thinkpad with a Samsung, to get a reasonable full window I had to unplug the vga, start xinit, and then plug in the vga, but I can live with that.) My questions: 1) What can I do to display the whole window on an external monitor? 2) Is there a monitor out there that would better support such use? 3) Would a Samsung T220HD 22 which claims to support 1680x1050 work, and is there someone in Toronto who sells it and would let me test it? (Craigs list doesn't qualify). -- david ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Do you still have access to the xorg.conf? Try to set a single configuration which only supports the native resolution of that screen. You also could have a test with a normal PC and the monitor.

(Craigs list doesn't qualify). You probably want to look into using the xrandr command to configure output for connected monitors. Try this first: xrandr --auto If that does not work, you may have to do something more sophisticated. For instance, I have a shell script that looks like this for when I connect my laptop to an external monitor: #!/bin/sh xrandr --auto xrandr --output LVDS1 --off xrandr --newmode 1680x1050_60.00 146.25 1680 1784 1960 2240 1050 1053 1059 1089 -hsync +vsync xrandr --addmode VGA1 1680x1050_60.00 xrandr --output VGA1 --mode 1680x1050_60.00 xli -onroot -border black -center /path/to/enso_16x9.png You should use this to find out the name of the display you identify in the --output line: xrandr -q You'll need to get information about your monitor's display parameters for the --newmode line, and the --addmode and --mode lines uses the same resolution string as in the --newmode line. The xli line is there just to re-apply my background image, because it gets a little out of whack when I change monitors like that. When I'm going to disconnect from the external monitor, I run xrandr --auto before disconnecting to get the laptop to recognize my laptop's built-in display again, then run xrandr --auto one more time after disconnecting the external monitor to get it to forget about the settings for the external monitor so my laptop display won't act funny because it thinks there's a larger external monitor still attached. I hope that helps. Let me know if you want any more information about how this works. -- Chad Perrin [ original content licensed OWL: http://owl.apotheon.org ] ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
