With Ubuntu. I have successfully used an extended desktop with different screens ( a HDMI Dell 19" at office via docking, and a VGA 17" (noname) at home) I had an issue not related to this with the graphics, for which I don't expect any feedback from this group, it is just to illustrate the circumstances: When I clicked with the right mouse button on a node in XCDP (http://www.ecmwf.int/products/data/software/sms.html) The GUI session hanged, untill I went to console (CTRL+ALT+F1) and terminated XCDP or its parent shell. This problem appeared to be generel for Ubuntu 10.04 local installs... Yes curiously enough, this was not an issue for remote X-sessions. A colleague installed ubuntu 10.10 and told me the issue with XCDP was resolved after this upgrade. So I performed the upgrade on my laptop and found also that the problem with XCDP was resolved. Alas I am no longer able to use extended desktop, "mirrored screens" setup does work however. I was looking in the Ubuntu forums for help and left a message there a couple days ago, no answer yet. Maybe any of you can help. A clean solution would be nice but any help to get me more insight on why this happens or were to go with troubleshooting is welcome. I first tried with the "Monitors" configuration tool of ubuntu, but this just fails without any error output. I then tried arandr, this fails with this output: XRandR failed: XRandR returned error code 1: X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 150 (RANDR) Minor opcode of failed request: 7 (RRSetScreenSize) Serial number of failed request: 32 Current serial number in output stream: 33 On the website http://intellinuxgraphics.org I found some more info and tried the following without much success. root@legolas:~# uname -a Linux legolas 2.6.35-22-generic #33-Ubuntu SMP Sun Sep 19 20:34:50 UTC 2010 i686 GNU/Linux root@legolas:~# lshw | grep -i graphic product: Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller product: Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller root@legolas:~# xrandr -q Screen 0: minimum 320 x 200, current 1440 x 900, maximum 4096 x 4096 VGA1 connected 1440x900+0+0 (normal left inverted right x axis y axis) 408mm x 255mm 1440x900 59.9 + 75.0* 1280x1024 75.0 60.0 1280x800 59.8 1152x864 75.0 1024x768 75.1 70.1 60.0 832x624 74.6 800x600 72.2 75.0 60.3 56.2 640x480 72.8 75.0 66.7 60.0 720x400 70.1 LVDS1 connected 1440x900+0+0 (normal left inverted right x axis y axis) 303mm x 190mm 1440x900 60.0*+ 59.9 1360x768 59.8 60.0 1152x864 60.0 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 DVI1 disconnected (normal left inverted right x axis y axis) TV1 disconnected (normal left inverted right x axis y axis) root@legolas:~# xrandr --output VGA1 --left-of LVDS1 X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 150 (RANDR) Minor opcode of failed request: 7 (RRSetScreenSize) Serial number of failed request: 32 Current serial number in output stream: 33 root@legolas:~# Thanks, Joost Ringoot
