You have been subscribed to a public bug: Hello, on ubuntu 9.04 dual screen worked, but was buggy (the external screen displayed only half (vertical split), but the fun was, that putting a window in full screen on that external display worked... only window mode had a bug :(
but now i tried my luck on 9.10, and ... it's no more working my netbook (with intel GMA 950) has a resolution of 1024x600 and the external monitor (a dell one) has a resolution of 1680x1050 so with the System => Preference => display tool (i guess the name, my ubuntu is French) i move the screens side by side with clone function disabled. and then GDM as X won't start here are the changes that the display tool made in my xorg.cong SubSection "Display" Virtual 2704 1050 EndSubSection when i start x with startx i receive a message that says "could not add fb" so i did a dmesg | grep drm here is the output : [ 1.695113] [drm] Initialized drm 1.1.0 20060810 [ 2.062285] fb0: inteldrmfb frame buffer device [ 2.062306] [drm] Initialized i915 1.6.0 20080730 for 0000:00:02.0 on minor 0 [ 2.136914] [drm] DAC-6: set mode 1680x1050 17 [ 2.448490] [drm] LVDS-8: set mode 1024x600 19 [ 12.974479] [drm:drm_mode_addfb] *ERROR* mode new framebuffer width not within limits [ 14.069862] [drm:drm_mode_addfb] *ERROR* mode new framebuffer width not within limits [ 15.241898] [drm:drm_mode_addfb] *ERROR* mode new framebuffer width not within limits [ 16.245814] [drm:drm_mode_addfb] *ERROR* mode new framebuffer width not within limits [ 17.061783] [drm:drm_mode_addfb] *ERROR* mode new framebuffer width not within limits [ 18.106475] [drm:drm_mode_addfb] *ERROR* mode new framebuffer width not within limits i can make further tests, so if you have any idea or tips, i'll be happy to help you guys resolve this bug... ** Affects: xserver-xorg-video-intel (Ubuntu) Importance: Undecided Status: New -- intel dual screen not working on karmic https://bugs.edge.launchpad.net/bugs/396898 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in ubuntu. _______________________________________________ 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
