Two monitors output mapped into one.
I have been facing a really weird problem.
After I start up X.org when I try to maximize any application window, instead of maximizing to the full 1280x800 I get a maximized window spanning 1024x768. However if I move the window around to make it aware that this is actually a 1280x800 display, the window maximizes properly.
What all I have tried.
I have tried using both gnome and XFCE and this problem persists. When I tried using XFCE I found out something really interesting - somehow the 1024x768 output of my projector/TV out and the 1280x800 display of my video card (Intel GM965/GL960) are BOTH getting mapped to my LCD monitor. Have a look at the screenshot I have attached. I can even independently set the wallpaper of the two monitors. Even lspci | grep -i graphics gives two outputs:
Currently I am using the i915 driver. Using the i830 driver solves the above problem but a) The framebuffer does not work, b) OpenGL does not work - both expected because the real driver for my device is actually the i915. Even when I link both the drivers as modules I uevent loads i915.
What may be the problem.
I think there may be
a) A problem in the i915 driver itself but then that would have to be a fairly recent bug since Ubuntu 8.10 did not have this problem.
b) More likely something wrong my xorg.conf. Is there a way to specify multiple displays exist and map only one of them to the LCD output?
I am currently using Arch Linux. I do not use the stock kernel but a compiled 188.8.131.52.
Any help / pointers / links will be a appreciated.
PS. If you use Acer 4720z or anything similar please upload your xorg.conf. That would be of great help.
Did you mean to mark this "[SOLVED]"?
If so, kindly post the solution -- even though this is an old post, it still might help someone else w/ the same, or a similar, problem.
BTW, nicely structured question -- I like the bold headings. Personally, I tend toward underling; but both accomplish the same thing. Rep to you.
