I have been burned in the past when trying to do a presentation from my laptop using Ubuntu. With only a few minutes and people waiting I have sometimes resorted to having to boot in Windows because I couldn't get the projector to work immediately. I know if I have all the time of the world and with the help of the Ubuntu forums I could probably have figured out what the problem was with those projectors, but I am just wondering if there are any tips on things to disable/enable/install as I prepare for a presentation? Should I disable compiz? Should I configure Xorg in certain way?

Please enlight me! I don't want to have to use Windows!

I Generally try to keep it simple. My default user profile all the soopers! I dont do presentations but watch a lot of movies (on projector too sometimes). While whatching a 3 hour movie, even on just the lappy, you would not want to have compiz and all the baggage. I created a diff user profile for this and login to that when needed. and once the settings are in, you dont need to worry, it just works from thre.

I'm having similar problems. I travel to different locations to do presentations, using various projectors and had no problems Ubuntu 8.40, but as soon as I installed 8.10 I would lock up when I connected to the same projectors that I used fine with 8.40. I had this problem originally with a clean install. I have now installed Compiz.... I have to use Windows to do my presentations...hate it

What else would you consider baggage?

conky, compiz, remote desktop, metacity (I use open box for the slim user prof), bluetooth, pretty much disable everything in session and only add pulse audio.. thats me :)

What hardware do you have (if unsure: run lshw)? How do you connect the projector?

I am connecting using a standard VGA cable, nothing fancy. Unfortunately, I do not often have access to the room before a presentation. I come to a place and I have to present in between other people, so thereis not much time to prep.


Here's my hardware:

Could you also give the output of 'xrandr'? For what I've seen now, you've a good change that your hardware is supported.

I tend to find all I need to do to get an external screen to work is log out and in again.

I have been successful at connecting to projectors in the past, but about 40% of the time something goes wrong.

Here's xrandr

I'm using a Dell 1330 with an Nvidia video card. I'm connecting with a VGA. i also rarely have more than 15min to set up. i have tried logging out and back on with no success. i get a signal to the projector it jut locks/ gets real slow so i can't advance to the next slide.
