Is there any way to configure the intel driver to allow for multiple X screens? I have a Dell Latitude E6420 where I got the intel driver to work by installing Fedora 15 beta packages: kernel-PAE-2.6.38.6-26.rc1.fc15.i686 kernel-PAE-devel-2.6.38.6-26.rc1.fc15.i686 xorg-x11-server-Xorg-1.10.1-14.fc15.i686 xorg-x11-drv-intel-2.14.0-6.fc15.i686 mesa-dri-drivers-7.11-0.9.20110509.0.fc15.i686 mesa-libGL-7.11-0.9.20110509.0.fc15.i686 mesa-libGLU-7.11-0.9.20110509.0.fc15.i686 xorg-x11-drv-mouse-1.6.99.901-2.fc15.i686 xorg-x11-drv-keyboard-1.5.99.901-2.fc15.i686 xorg-x11-drv-evdev-2.6.0-3.fc15.i686 xorg-x11-drv-synaptics-1.4.0.901-1.fc15.i686 TIA for all your help, Gabriel ^ permalink raw reply [flat|nested] 6+ messages in thread

You should see some information about the connected monitors. If your second monitor is connected to DVI1 and your first monitor is a 1600x900 lvds, try something like "xrandr --output DVI1 --pos 1600x0" After that your 2nd monitor should show the right of your desktop, and your desktop should be enlarged by the x-resolution of the 2nd monitor. Read man xrandr. With current git Xorg I can connect two 1280x1024 monitors to my system (i915GM). No special configuration is needed. With current git Xorg it does work. Well, back in January it did not work and it was a 100% reliable way to crash the PC ;-) cu, Knut ^ permalink raw reply [flat|nested] 6+ messages in thread

Read > man xrandr. Getting this to work is indeed trivial. In fact, GNOME auto-detects the display, and extends my desktop by default. This is not what I want. What I want is not to extend my desktop, but to have an X server that consists of multiple (in this case two) separate screens. So, on one screen, when you launch an xterm and type echo $DISPLAY, you get :0.0 and when you launch it on the other screen and type echo $DISPLAY, you get :0.1 ... this is the kind of setup where you /can't/ drag windows across monitors. OTOH, this is the only setup where switching virtual desktops on one monitor does not affect the current virtual desktop on the other monitor, nor will accidentally windows appear on the wrong monitor. Unfortunately I cannot seem to find a single setting in either the device section for intel, or in the ServerLayout section, or in the Monitor section of the xorg.conf file that explicitly /disables/ extended desktop. Please let me know if such a setup is possible, TIA, Gabriel ^ permalink raw reply [flat|nested] 6+ messages in thread

I don't know if it's possible, at least I failed too. But: A generic solution would be to use two Xephyr <http://www.freedesktop.org/wiki/Software/Xephyr> X clients/servers on top of the "real" Xorg server. cu, Knut [-- Attachment #1.2: Type: text/html, Size: 991 bytes --] [-- Attachment #2: Type: text/plain, Size: 159 bytes --] _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx ^ permalink raw reply [flat|nested] 6+ messages in thread

No, we removed that capability several years ago; it was an ugly hack. -- keith.packard@intel.com [-- Attachment #1.2: Type: application/pgp-signature, Size: 189 bytes --] [-- Attachment #2: Type: text/plain, Size: 159 bytes --] _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx ^ permalink raw reply [flat|nested] 6+ messages in thread
