How to disable Fn-Spacebar Hotkey on Toshiba Laptop

Hi all. Pressing Fn-spacebar on  my Toshiba P-20 causes my screen resolution to toggle between 1024x768, 1280x1024 and its native 1440x900 (desired) setting.

The problem is that I use an application that has a repeated CTRL-spacebar hotkey that I need to use. If  my finger slips onto the Fn key while I press spacebar, the darned screen resolution swaps, causing me all sorts of headaches.

Does anyone know what feature / control panel / registry setting or other setting can be used to deactivate this feature. I can't imagine it being useful to anyone, but that's besides the point. If you have any info, I sure would appreciate it!

I don't know for sure ... but those types of shortcuts can often be turned on/off either in (a) the BIOS Setup; if it's a universal mode setting that does not depend on Windows;   or (b) in Display Properties (probably on the advanced tab of Settings) if it's a Windows shortcut.

I'll check the BIOS but I know for sure it's not under Settings > Advanced or the nVidia control panel either, which is where it would seem the most logical to me. But I have all nVidia CP functions turned off and there are no shortcuts available in Advanced settings. any other ideas?

Simple way to confirm if it's a BIOS setting or a Windows driver setting:

Boot to the BIOS Setup, or to a Windows 98 boot disk (or any other floppy-based environment ... for example MemTest86+) and see if the Fn-Spacebar combo changes the resolution.  If not, then it's a Windows driver hotkey ... and there HAS to be a setting in the nVidia controls to disable it !!   These kinds of things are often "hidden"  (i.e. buried in a not-so-obvious submenu).
I don't have a PC handy with a newer nVidia card to try it ... mine all use ATI-based cards ... but if you have patience and look very carefully I'm sure you'll find it :-)

Hmm. I didn't see any settings in the BIOS that had anything to do with keyboard combinations. It looks like I will be hunting for a while...

does anyone else have any suggestions?

Does the key combination change the display resolution if you're "outside of Windows" ??  [the test I suggested above]

... because if it does NOT, then there won't be any settings in the BIOS => they will be in the nVidia settings.  

I booted up an older machine I have with an nVidia card and took a look at the nVidia settings.   If I go to Display Properties; the Settings tab; and click the Advanced button; and then click on the tab for the display adapter, then expand Desktop Management ... there is a HotKeys section.

While this may be slightly different for your system (depending on which version of nView you have and exactly which adapter), there is almost certainly an equivalent path to the hotkeys => and all you have to do is disable the hotkey that's causing the issue :-)

Thanks for the additional comments. in the nView manager, I have everything turned off - desktop management is not enabled, and all my hotkey options are deactivated - there are no hotkey mappings enabled in the nView desktop manager. So, something tells me it's not nView, it's Toshiba. the IBM thinkpad has a similar problem but for some reason that one is quite heavily documented on the Internet, while the Toshiba issue is not. I have, of course, logged a ticket with toshiba, but I will be shocked if they respond.

I'll keep digging. Meanwhile, additional ideas or suggestions would be appreciated!

Thanks

I'm still curious whether the key has any effect outside of Windows -- does it ????

As we guessed, the hotkey combination did not have any effect outside of Windows. In fact, it wasn't even recognized on the Windows login screen (where you choose the user you want to log in as). Only once actually logged into the Window XP Home Edition environment did it immediately become active.

Arghhh! I hate this feature!! How to deactivate it?

Thanks for your continued interest in this question.

You're missing something in the nVidia drivers --- it's clearly a function of the drivers.

First, see if it's a startup program or the base drive:  Run MSCONFIG  (Start - Run - MSCONFIG) and disable ALL of the items on the Startup tab.  Reboot (it will warn you about the diagnostic startup on reboot) and see if you still have the behavior.

I have determined from the Toshiba web site and from a lot of sniffing about that it is in fact a toshiba control panel called "eKey", which can be uninstalled using your standard windows add/remove programs.

removing the Toshiba hotkey control panel will disable the Fn-spacebar feature, but does not seem to negatively impact the other Fn-hotkeys such as CRT/LCD switching or the brightness controls etc.

Thank you to all for looking into this issue with me. I will now close the topic.

gary, I will split points with you because of your continued efforts, although it didn't prove to be the solution.

Many thanks again!

Guess I can't split points between you and myself, so I've accepted your answer. Once again, thank you.
