A new 'intel' driver is meant to replace it, but as of end 2007 it seems not as stable as i810 yet, notably it [https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/138256 crashes at suspend time] | + | This chip is supported by the 'intel' driver as part of the X.Org distribution. |

| |
| − | ======MergedFB======
| |
| − |
| |
| − | With MergedFB you can use an external Display with another resolution.
| |
| − | To enable MergedFB, you need to edit your Screen-Section and your Device-Section.
| |
| − |
| |
| − | In the Screen-Section, you need to add a Resolution for all resolutions. Your Laptop-Display and your External Display.
| |
| − |
| |
| − | And you have to add a "virtual" Resolution which is the biggest resolution of both. Like this:
| |
| − |

| |
| − | Device "Intel Corporation Mobile Integrated Graphics Controller"
| |

| |
| − | Virtual 1280 1024
| |
| − | EndSubSection
| |
| − | EndSection
| |
| − |
| |
| − | In your Device-Section of the Card, you need to add some Tags. MetaModes consits of every Resolution you need to use.
| |
| − | This looks like this.

| |
| − |
| |
| − | I had to set the MergedXinerama to false because it reported a Screensize of 0,0,-1,-1 which makes the Windowmanager behave funny.
| |
| − | But with this setup it is possible to use RandR to switch from the Resolution of your Laptop-Display to the Resolution
| |
| − | of your bigger external Display without quitting your X-Session. Your Laptop-Display will then scroll to show the part of your
| |
| − | Desktop where your mouse is.

| |
| − |
| |
| − | There seems to be many issues trying to do this from within {{path|/etc/X11/xorg.conf}} or {{path|/etc/X11/XFree86.conf}}. The solution for basic projector or cloned output is to use the [http://i855crt.sourceforge.net/ i855-crt] program. Remember that this program is very raw and could damage your display equipment.
| |
| − |
| |
| − | Once this is installed an example command would be (with root permissions):
| |
| − | :{{cmdroot|i855crt swcursor on "1024x786@85"}}
| |
| − | to stop it enter
| |
| − | :{{cmdroot|i855crt off}}
| |
| − |
| |
| − | The video mode in quotes is defined in {{path|/etc/i855crt.conf}} or {{path|~/.i855crt.conf}}.
| |
| − | {{Fixme|This is specific usage information for that tool. Introducing an own tool page for it should be considered or joining this with other information in a display cloning howto page.}}
| |
| − |
| |
| − | Using MonitorLayout and Clone options it is possible to setup cloned display with X.Org (tested with 6.9.0). Dualhead supported by Xorg driver.
