Re: xorg problem--dual-head, Debian vs. Ubuntu
Hi there! I was with the same machine and problem. t60, with an external monitor - 1366x768. So, I've copied this xorg.conf (that debian squeeze omits) and changed the values to my configuration, enlarging the virtual area. then restarted X, and when I hitted preferences monitors, and everything worked well... =) thanks! fernão -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

I'm sorry for the delay--I responded to this yesterday, also posting my xorg.conf file, but I realized that the message apparently never went through. I'll skip the conf file this time. Does the following work? xrandr --output VGA --mode 1280x1024 --left-of LVDS No, that just gives me: $ xrandr --output VGA --mode 1280x1024 --left-of LVDS warning: output VGA not found; ignoring Which is odd, because when I ran xrandr --query it certainly did think it was there. In any event: I did play around with the conf file again, based on the suggestions elsewhere in this thread, and despite the fact that I had unsuccessfully tried similar things before, this time I got it to work, so I successfully have a conf-file based dual-head setup that's adjustable via the Display Preferences app. I do wonder why this is handled differently in Ubuntu vs. Debian--I had imagined that this sort of thing would be based just on the implementation of X, but if it's true that it's some deep tweaking that Ubuntu is doing, I guess I just have to acknowledge that they're different in this regard. I'd think that it would be useful to have Debian do this too (I don't think that everything should be done for me, but here I can't see any reason why it's a downside for the OS to handle it entirely).

xorg problem--dual-head, Debian vs. Ubuntu
Hi. I'm running Debian unstable on a Lenovo T60. I'd like to run this dual-head with an external monitor, but have been having some problems that I tried to solve but eventually gave up on because I'm so lousy with X configuration. However, I recently discovered that things work fine out-of-the-box with Ubuntu 9.10, running on the same computer (via a live USB stick). So I'm wondering if there's some way to figure out why there's a difference, and whether I can get the Debian system working in the same way. The T60 has a Radeon X1300 card; the built-in monitor runs at 1400 x 1050. I'm trying to attach a 1280 x 1024 external monitor through the VGA port. I'm running Xorg 1.7.5, and I do not have an xorg.conf at all, I'm letting Xorg generate the configuration. When I plug in the external monitor, and run Display Preferences to try to set up the two displays, I get a popup message reading The selected configuration for displays could not be applied[:] required virtual size does not fit available size: requested=(2680,1050), minimum=(320, 200), maximum=(1400, 1400). I've Googled this and found a few bug reports that don't, however, clarify what's going on. But the notable thing for me is that running Ubuntu 9.10, which is running Xorg 1.6.4, this Just Works, with everything else identical--same hardware, same lack of xorg.conf file, etc. I'd be grateful for any suggestions. I'd vastly prefer _not_ to have to start messing around with the configuration file, because apart from this one issue, I don't seem to need one, and Ubuntu doesn't seem to need it either. Thanks.

But the notable thing for me is that running Ubuntu 9.10, which is running Xorg 1.6.4, this Just Works, with everything else identical--same hardware, same lack of xorg.conf file, etc. I have seen the same problem, and I know no solution that does not involve an xorg.conf file. However, I do not think it must be very hard. When using several monitors, they all form a larger virtual desktop together. If you have two monitors of size 1280x1024 next to each other, the virtual desktop must be at least 2560x1024 for the two to fit it. This is adjusted in the xorg.conf file, as follows: Login as root in text mode (either by booting into recovery mode, or switching with ctrl-alt-F1) and ensure your X is not running (run /etc/init.d/gdm stop if you are using a standard gnome desktop). Then run Xorg -configure. This should create a file xorg.conf.new with contents suited to your hardware. Now open that file in a text-editor and look for a Screen section to which you add a Display section, as shown in this example I found on the internet: Section Screen Identifier Default Screen Device Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller Monitor Generic Monitor DefaultDepth 24 SubSection Display Depth24 Modes1600x1200 1280x1024 1024x768 800x600 640x480 # ADD A VIRTUAL LINE TO PROVIDE FOR THE LARGEST SCREENS YOU WILL HOTPLUG Virtual 2048 2048 EndSubSection EndSection Some more information is available on the man page (man xorg.conf). From the error message you quoted, you may want to choose at least Virtual 26801050 in your configuration. Now save the file as /etc/X11/xorg.conf and restart X. Hopefully the error is now gone. If that did not work, you should be able to just delete the file /etc/X11/xorg.conf, and then (after restarting X) you should be back to the configuration you had before. Somehow ubuntu either uses larger defaults for the virtual screen size, or adjusts them automatically while the xserver is running, but I do not know enough to comment on what is a reasonable default behaviour in general.

Jesse Sheidlower There may be some way to do this without an xorg.conf, but I'm not familiar with it. A simple conf, like the following, might work, though, and is pretty simple to try... Section ServerLayout Identifier dual head configuration Screen 0 Screen0 0 0 EndSection Section Device Identifier Videocard0 Option monitor-VGA1 monitor1 Option monitor-VGA2 monitor2 EndSection Section Monitor Identifier monitor1 Option Position 0 0 Option DPMS true EndSection Section Monitor Identifier monitor2 Option RightOf monitor1 Option DPMS true EndSection Section Screen Identifier Screen0 Device Videocard0 DefaultDepth24 SubSection Display Virtual 2680 1050 EndSubSection EndSection The trickiest part of this is determining the screen names (VGA1 and VGA2 in my example). To find yours, run xrandr (as normal user, not root) and look for the lines like connected 1400x1050 for each screen - the 's are what you're looking for. Yep...
