@Jay You were right: I had compiz enabled (I forgot I enabled it after I stuck to no Virtual line in xorg.conf).
Without compiz, virtual resolutions that DON'T exceed 2048 pixels on either axis work fine: X starts correctly even if xorg.conf contains a Virtual line; I can use two monitors without having them mirrored. Unfortunately setting a virtual line with either axis larger than 2048 will not work, due to a kernel limitation (apparently the fix is in upstream kernel): [ 7099.508567] [drm:drm_mode_addfb] *ERROR* mode new framebuffer width not within limits -- [i945GM] dual screen not working with virtual resolution enabled: just a blank screen with a mouse pointer https://bugs.launchpad.net/bugs/383345 You received this bug notification because you are a member of Ubuntu-X, which is the registrant for xf86-video-intel. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
