Re: [Lazarus] Unable to debug GUI
..reminds me at a bug in intel Drivers i had trouble with on Linux-Mint cinnamon: try this (quote from a forum http://forums.linuxmint.com/viewtopic.php?f=221t=146477 ): * I have a Intel GPU, and i have these annoying black windows. But you can do it this way: create as root the file /etc/X11/xorg.conf in terminal type ( if you don't have a /etc/X11/xorg.conf ) : sudo touch /etc/X11/xorg.conf open editor in admin mode: gksu gedit /etc/X11/xorg.conf ... and write/copy these lines: Section Device Identifier Card0″ Driver intel Option AccelMethod sna EndSection reboot if that doesn't help do in terminal: rm /etc/X11/xorg.conf to delete it again seems to work ok for me, but i have to test this some days first. update: 10.07.14 ..still working ok! That was the solution for these annoying black pop-up windows!! *** Am Montag, den 14.07.2014, 11:08 +0200 schrieb Michael Van Canneyt: Hi, I have a machine on which I'm completely unable to debug GUI programs.

Try debugging you app on a second instance of X ( display :1) in some cases X locks up when a breakpoint happens inside a X event.

What works with CentOs may fail with Ubuntu 1) Use: Run - Run Parameters - Use launching application 2) Your launching application will be xinit, with a :1 parameter to specify a different display. Sort of: /usr/bin/xinit -e /path/to/executable [Command line parameters] -- :1 for further details, man xinit and man xterm (which in this setup is launched by xinit).
