Question Ubuntu duel monitor (dvi + vga)


Im using a laptop brand Thinkpad 501 type 2082-8wg. And i have problem getting it to work with 2 monitor when it is in it dock.

I know it is working for when im booting up and it come to the login screen. I have 2 monitor. But logging in and number 2 monitor shutdown.

I have tried countless time/month to alter my xorg.conf file so i can get the ("#%#%#) monitor to work. (pardon my french).

Hope the is som nice soules in here who can guide my in the direction so i can see the configuration my laptop has when it is at the login screen and i can replica it over to my xorg.conf.

And before i forget the grafic card i a ATI Mobility Radion HD 3650.

When this problem is solved im allow to use linux at work...

Which flavour of Ubuntu are you using? With the older versions (Gnome 2 or Gnome 3 Classic) you will find the monitor settings under Preferences. With Unity and the "standard" Gnome 3 it seems to be either in System Settings or Display on the menu you get when you click the On/Off icon in the top left.

I've found that most versions of Ubuntu are very good with dual monitors, but there are some things to note about laptops, dual monitors & Linux.

I've found that running an external monitor or a projector works best if they are the same resolution. Secondly, you may find it best to make sure the external monitor is not "enable" by default in the monitor setup. Otherwise the graphics card is not sure which to use. When you dock you will have to open the Display settings, click on "discover displays" and you should find that if it can drive the monitor it "just Works".
