I've been struggling with Lazarus and Gnome shell running Ubuntu 11.10. Find dialogs, tabs, and Menus don't work. Anyone working on any of this?

While I don't encourage development on Unity shell, I do think that it is essential for Lazarus IDE to support latest Gnome variations.

I use neither Ubuntu nor Gnome nor Unity, but I'm curious:

I couldn't even get the Lazarus IDE (compiled with LCL-Qt) to start up.

Saying that, I was running off the Live CD. But in my defence, I did copy all the Qt required libs (eg: libphonon, libQtWebKit, libQt4Pas etc) to a known location and setup the LD_LIBRARY_PATH environment variable to point to the location of those Qt libs. I briefly saw the IDE splash screen, then simply the prompt that an exception occurred. Selecting the Ignore button (instead of terminating the app), the IDE crashed out to the command prompt.

A native fpGUI app as well as a LCL-fpGUI test app worked without problems.

I was using Lazarus 0.9.30.x code to test with FPC 2.5.1

Start it in GDB and then post the backtrace.

I'll have to install Ubuntu 11.10 in a VM session first. By default Ubuntu doesn't include developer tools (unlike nice distros like Slackware).

Give me a hour or so to prepare the VM, and I'll give you more feedback.

Does it work when you do:

$ export LIBOVERLAY_SCROLLBAR=0
$ lazarus

?

I know it solves some problems, I don't know if all.

From other people I know (I haven't tested myself) QT version works fine.

See attached file.

I also made sure that the 'lazarus' executable is actually runable, by running it under my 64-bit Ubuntu (even though it is a 32-bit Qt executable) - which it did. I have all the required libraries installed in my host system and in the VM system.

Ok, Thanks. I added it to my .profile.

It seems that even with this option, file dialogs are not accepting input and can't be closed. Dialogs only close when I close the form that created it.
