I've run into a screen-resolution problem with an external monitor. I'm using a notebook with a ATI x1400 graphics card, 1280x800 screen and XFCE. An external Samsung Syncmaster 203b with 1400x1050 resolution monitor is connected to the vga port (no dvi port on my notebook). I only want to use the external monitor with the notebook screen turned off.
This setup has worked with the ATI Catalyst and xf86-video-radeonhd driver. After support for Catalyst stopped and reading that xf86-video-ati was more up to date than the xf86-video-radeonhd driver I decided to give the xf86-video-ati a go.
Without a xorg.conf file the resolution of my external screen isn't detected and I end up with the same 1280x800 desktop on both screens. With the xorg.conf file below I see 1400x1050 resolution on my external screen and part of the desktop on the notebook screen. But when I maximize a window it gets maximized to 1280x800, not to 1400x1050 like I would like. I can drag a window to fill the screen though. In my XFCE desplay settings I can only see one screen ('screen 1) with maximum resolution 1280x800.
With 'xrandr --output LVDS --off' I get the situation I want: only external screen and maximizing windows will use 1400x1050. My XFCE display settings now show again only 'monitor 1' but with maximum resolution 1400x1050.
My question:
- Is there a way to set this without using the xrandr command , using the xfce display settings dialog?
