Hi,

I'm having problems with the xinerama support. I follow the installation steps and I run autoreconfigure. The xmonad binary is also linked with libXinerama.so.

Can you check that X11-extras found and built with Xinerama support? Perhaps provide the configure logs for X11-extras.

I think so, this are the steps that I'm following $ runhaskell Setup.lhs configure ... checking X11/extensions/Xinerama.h usability... yes checking X11/extensions/Xinerama.h presence... yes checking for X11/extensions/Xinerama.h... yes configure: creating ./config.status config.status: creating X11-extras.buildinfo config.status: creating include/config.h config.status: include/config.h is unchanged $ runhaskell Setup.lhs build Preprocessing library X11-extras-0.2...

Attached is also the buildlog from xmonad. If it helps, I'm usisg xorg 1.3.0 and I'm activating the second monitor through the command xrandr --output VGA --left-of LVDS Thanks

Hmm, this should work (I run the same command every day). Are you running xrandr before or after xmonad starts?

after xrandr. Im using the same .xsession file as for ion3, I'm only changing the last line, from exec ion3 to exec xmonad.

Does xmonad pick up the right screen geometry after restart (mod-q, make sure xmonad is in your path)?

the same problem persist, also after closing all the windows and openining a new xterm. Xmonad is in the path.

Has your server loaded the Xinerama extension? Check with 'xdpyinfo | grep XINERAMA'.

yes, it works well with ion3 + the xinerama module and with metacity.

PS - you should try running Jason's little diagnostic script from an earlier post in this thread

I cannot find the script in the archives, could someone mail it to me? Thanks.

The output is: Nothing [Rectangle {rect_x = 0, rect_y = 0, rect_width = 2304, rect_height = 1024}] the version of x11-extras and xmonad, are the darcs from yesterday.

Ok. We're officially mystified. If X11-extras was correctly built with Xinerama, and Xinerama is enabled on your system, the above should have found a couple of screens -- its a simple call into X after all.

It's probably worth looking at what's actually in Graphics/X11 in the source for X11-extras. I managed somehow to get to the situation where everything was linked to libXinerama, but it was still using the dummy functions that didn't use it. (Though the nm output you gave also looks plausible, so probably this isn't it.) [...]

If you managed to do that, it's definitely a bug. Are you able to reproduce this behavior?

Almost certainly not. It was quite possibly user error: I was messing about quite a bit, trying to work out what was wrong. My guess is it won't happen to anyone following the instructions properly (in particular, running autoconf), or just using more recent tarballs or darcs downloads.
