View Full Version : Cannot switch task?

October 10th, 2008, 11:50 AM
I am having the most annoyingly simple problem. When setting the backend up I need to switch task to the terminal, but alt-tab does nothing. I am using 8.10 beta.

Why? or how can I get round this?

Alt + Tab will only switch between tasks already running, not start a fresh one, so if backend setup is the only app running, it will do nothing.

ALT+F2 should bring up a run dialog.
xterm to open the X terminal.

See that is why I am having such a problem. Alt-tab appears not to work when I have other programs running eg firefox, and alt-F2 does not work for me either?!

does alt+tab work when mythtv-setup is not running? Maybe for some reason your alt key isn't getting captured at all...

No it does not appear to be working outside myth either. I don't know how to fix this.

does alt anything work? Like keyboard shortcuts, or in most windows (like firefox) press Alt-F to get to file menu? What desktop environment are you using?

No alt-f did not work in firefox. I am using mythbuntu 8.10 beta, so the desktop is sort of xfce.

Maybe you chose the wrong keyboard type when installing. You might want to use
xev and see what pressing the "alt" key generates. I think you can switch the keyboard type in xorg.conf. Not my area of expertise, you might want to ask this on the hardware part of the forum.

When I installed I selected uk keyboard and I have a microsoft natural pro keyboard. Was this the wrong choice?

xev gives me:

FocusOut event, serial 34, synthetic NO, window 0x2600001,
mode NotifyGrab, detail NotifyAncestor

FocusIn event, serial 34, synthetic NO, window 0x2600001,

Sorry I don't know why a smiley appeared but it is really a : and a (

...state 0x18, keycode 64 (keysym 0xffe9, Alt_L), same_screen YES,...

Indicates you pressed the left Alt key so I think it is being interpreted fine... At this point I have no idea what problem is. Sorry... Hopefully some others will be along to help you.

Just a thought. Does your keyboard have multifunctional(programmable) F-Keys? I've got a Logitech Cordless jobbie, and there's an F-Mode button that switches between standard and programmed mode for the F-keys.

After boot, ALT+F2 works. Press the F-Mode key once, and ALT+F2 does nothing. It doesn't affect ALT-TAB, so may be completely unconnected, but as your 'ALT_L' key seems to be detected OK, it just occurred to me that it might not be the 'ALT' that's the problem...

I have one of those keyboards attached to another computer, but the one I am having the problem with does not.

But, I have had a result, even though I was getting a positive response with xev I tried another keyboard, which works!

This now sounds like a bug to me should I post it?
