LXDE Forums

I've recently installed LXDE and I'm pretty sure Alt-Tab used to work at first a few days ago, but now after some configuration changes and lots of new installations and setting things up, alt-tabbing between windows is broken in that the focus is left to the currently selected window and not the one I selected in the alt-tab dialog. The only way to give focus to another window is to click on the taskbar. I'm attaching a showing the effect.

Some further developments into this issue: I tried running openbox with --debug and/or --debug-focus. Unfortunately when I do so, it does not pull settings files from the usual location and also the bug wasn't reproduced. So what I did was copy the default rc from /etc/xdg/openbox/rc.xml over the ~/.config/openbox/lubuntu-rc.xml and this also fixed the alt-tab problem. I'm now gradually restoring my settings so I can isolate what entry specifically was causing the issue and I'll get back if I find it.

thank you for posting what is essentially the solution!
