Ipad to Projector using keynote and other VGA apps in ios 4

i'm very disappointed. I'm working teaching photography and showing galleries and presentations to my paying students. Everything was ok before I upgraded to ios 4.0 and now vga out, on the apps supporting it, is not longer working.

I know this doesn't help, but it's working just fine (and just like before) on my iPad.

Are you both using the latest version of Keynote (1.3) that came out at the same time as iOS 4.2.1? Did you try the usual troubleshooting methods (restarting / resetting the iPad)?

Thanks! Already done , immediately but nothing worked. I found other people on the web, talking about the same problem but no solution. In a two or three weeks period. Is ipad upgrading bringing us back to windows switching off and on trick?

Sorry... My upgrade was to 4.2.1 version

Wonder if all the people that bought ipad, cck and vga connectors, unusefull with ios 4.2.1, would ask money back cause what was sold wasn't what they have got in their hands...

Last week I checked the VGA connector using iOS 4.2.1... it works.

I must apologize with all of you folks.
a complete reset solved the problem.

Before you do any of the resets below try this first.
Press and hold both the Sleep/Wake button and the Home button for at least ten seconds, until the Apple logo appears.

Here are the descriptions for the different reset settings:

Resetting iPad Reset all settings: Choose General > Reset, then tap Reset All Settings. All your preferences and settings are reset. Information, such as your contacts and calendars, and media, such as your songs and videos, aren't deleted.

Erase all content and settings: Choose General > Reset, then tap “Erase All Content and Settings.” This resets all settings to their original values and erases all your information and media.

Reset network settings: Choose General > Reset, then tap Reset Network Settings. When you reset network settings, your list of previously used networks and VPN settings not installed by a configuration profile are removed. Wi-Fi is turned off and then back on, disconnecting you from any network you're on. The Wi-Fi and “Ask to Join Networks” settings remain turned on. To remove VPN settings installed by a configuration profile, choose Settings > General > Profile, then select the profile and tap Remove.

Reset the keyboard dictionary: Choose General > Reset, then tap Reset Keyboard Dictionary. You add words to the keyboard dictionary by rejecting words iPad suggests as you type. Tap a word to reject the correction and add the word to the keyboard dictionary. Resetting the keyboard dictionary erases all words you've added.

Reset the Home screen layout: Choose General > Reset, then tap Reset Home Screen Layout.

Reset the location warnings: Choose General > Reset, then tap Reset Location Warnings.

What does a complete reset mean? Where do I find this button? Is it under "settings"? Does it affect my files, photos, or apps on my device?

Thanks in advance for inputs.

David provided you with a complete data dump which, hopefully, addressed some part of your question. My input would be a bit different.

Consider spending just a little time going through your User's Manual, within which you'll find all of the info he provided and, of course, a whole lot more. You're sure to pick up a few new things and, more importantly, will have a much better feel for what kind of answers it can provide.

A swing or two through the iPad support pages, locates at apple.com, could prove equally helpful.

Safari... Bookmarks... iPad User Guide. I tend to forget that there is one there.
