I suspect that I'm applying the patch incorrectly, how to do that in a correct way? Sorry, this is an old email, but I'm digging through my Debian mailbox archives... xorg now supports sharing virtual terminals, so you can run multiple full X servers, with no need for xephyr anymore. They get device input from evdev, instead of from the console keyboard. I have a working g965 + PCI r128 multiseat system (two PS/2 keyboards and two USB mice plugged into an Intel DG965WH mobo). I have to get the PCI card initialized with int10, but if int10 is enabled when I start two X servers at once, they both get the g965 video BIOS or something, and it can't initialize. So my normal xorg.conf has i2c, ddc, int10, and vbe commented out. I was going to post some snippets of my xorg.conf, but it's going to be a lot more useful to actually post the whole thing. (and the number of snippets was climbing...) And the Device and Serverlayout sections have sprinklings of Option NoInt10 true Option NoDDC true # somehow r128 sees the i810's VBE BIOS... Option SingleCard true # like IsolateDevice Option InitPrimary true I'm sure not all of these are necessary, but that's where I got to by trial and error. I have a normal (multihead single seat) xorg config that doesn't disable POSTing the video cards, which I use to get the video cards initialized. # sudo X -config xorg.conf.probe -probeonly # then # startx /usr/bin/fluxbox -- :1 -layout seat1 -sharevts vt8 # startx /usr/bin/fluxbox -- :0 -layout seat0 -sharevts vt7 The key of course is the -sharevts. If you google around, you can find how to configure gdm to start the X servers, and for more tutorials on this. http://blog.chris.tylers.info/index.php?/archives/14-Multiseat-X-Under-X11R6.97.0.html http://en.wikibooks.org/wiki/Multiterminal_with_evdev I had been hoping to give the PCI video card to a Xen hardware-virtualized domain, and give my dad a windows desktop. That doesn't work (yet?). I might do more with multihead when I get more RAM (2GB DIMMs are becoming available :), but I still need to reboot occasionally when the g965 driver crashes. (It doesn't lock the machine at all, but rebooting (or suspend-resume, when that works at all), is the only way I've found to get the g965 video hardware back to a useable state.) I have used multiseat while playing vegastrike on the g965 head, with out-of-game tools on the r128 head. Having a separate keyboard is a big win when using games that take over the X server and can't be switched away from easily. Well, CTRL+ALT+Fx to another X server might work.

Xephyr on AMD64 Etch a.k.a multiseat
Hi, I'm following this howto[1] to make a multiseat system on AMD64, I saw there were precompiled binaries for Xephyr, and I started to create some packages with apt-get source applying the patches on that page[1] 1.http://en.wikibooks.org/wiki/Multiterminal_with_Xephyr The steps I followed to apply the patches were: apt-get source xserver-xephyr sudo apt-get build-dep xserver-xephyr wget http://www.c3sl.ufpr.br/multiterminal/howtos/xephyr-patches.tgz mv xephyr-patches/kdrive-evdev.patch xorg-server-1.1.1/debian/patches/46_kdrive-evdev.patch mv xephyr-patches/kdrive-ephyr-evdev.patch xorg-server-1.1.1/debian/patches/47_kdrive-ephyr-evdev.patch cd xorg-server-1.1.1/ fakeroot dpkg-buildpackage cd .. dpkg -i xserver-xorg-core_1.1.1-21_amd64.deb \ xserver-xorg-dev_1.1.1-21_am d64.deb xdmx_1.1.1-21_amd64.deb \ xdmx-tools_1.1.1-21_amd64.deb xnest_1.1.1-21_amd64.deb \ xvfb_1.1.1-21_amd64.deb xserver-xephyr_1.1.1-21_amd6 \ Then when I try to make /usr/sbin/Xephyr.sh -display :0.1 -br -xauthority \ /var/lib/gdm/:0.Xauth -geometry 1024x768+0+0 -keyboard \ /dev/input/kbd1mt -mouse /dev/input/mouse1mt,5 -use-evdev -dpi 92 I get an error that sugests the patches weren't applied correctly, because the options geometry, keyboard and evdev are not allowed. Mi questions : * Does anyone have experiences of multiseat with AMD64? * If so, the Xephyr approach or something else?

P.D: I have the graphics card working with the two monitors fine, but I'm not able to make the keyboard and the mouses with the monitor become an independent seats. Can you run the graphics card as two seperate X servers though? I have only ever heard of people doing multi user setup using seperate PCI video cards that could be run with a seperate X config for each card by specifying the PCI ID for each device. I guess if you disable cinerama, you might be able to get screen 0.0 and 0.1 managed seperately somehow. I hadn't heard of xephyr before, although it sounds like it is intended to manage dividing one X session into seperate sessions.

Re: Xephyr on AMD64 Etch a.k.a multiseat
I do a few atemps but not really success... If you have multiple video cards listen ti Lennart... If you have only one video card Xephyr seems the right option, and I suggest try first with the original patched code in a chroot, If I understand clearly the trick is configure NOT MOUSE to X beacuse Xephyr should use it raw... good luck let us know success :-) On 6/8/07, Igor TAmara [EMAIL PROTECTED] wrote: Hi, I'm following this howto[1] to make a multiseat system on AMD64, I saw there were precompiled binaries for Xephyr, and I started to create some packages with apt-get source applying the patches on that page[1] 1.http://en.wikibooks.org/wiki/Multiterminal_with_Xephyr The steps I followed to apply the patches were: apt-get source xserver-xephyr sudo apt-get build-dep xserver-xephyr wget http://www.c3sl.ufpr.br/multiterminal/howtos/xephyr-patches.tgz mv xephyr-patches/kdrive-evdev.patch xorg-server-1.1.1/debian/patches/46_kdrive-evdev.patch mv xephyr-patches/kdrive-ephyr-evdev.patch xorg-server-1.1.1/debian/patches/47_kdrive-ephyr-evdev.patch cd xorg-server-1.1.1/ fakeroot dpkg-buildpackage cd .. dpkg -i xserver-xorg-core_1.1.1-21_amd64.deb \ xserver-xorg-dev_1.1.1-21_am d64.deb xdmx_1.1.1-21_amd64.deb \ xdmx-tools_1.1.1-21_amd64.deb xnest_1.1.1-21_amd64.deb \ xvfb_1.1.1-21_amd64.deb xserver-xephyr_1.1.1-21_amd6 \ Then when I try to make /usr/sbin/Xephyr.sh -display :0.1 -br -xauthority \ /var/lib/gdm/:0.Xauth -geometry 1024x768+0+0 -keyboard \ /dev/input/kbd1mt -mouse /dev/input/mouse1mt,5 -use-evdev -dpi 92 I get an error that sugests the patches weren't applied correctly, because the options geometry, keyboard and evdev are not allowed.
