Xvesa - disable virtual console switching?

[Alatun]

I've built a thin client boot environment using TC to start rdesktop and automatically connect to a Windows 2008 TS. This setup will be used with a dozen computers to do computer based training. To prevent participants doing bad things I'd like to get some kind of kiosk mode.

I already configured Xvesa with "-nozap" to prevent killing the X server, but it is still possible to do "ALT+F1" to switch to the first text console and do a "CTRL-C" to get to the linux shell. Any ideas how to prevent console switching? (I want to stay with Xvesa, because of the package size). I already searched the online docs, but was unsuccessful so far.

There's no support for that in tinyx currently, patches welcome. An alternative way is to grab the keys (alt, or all F-keys), which is done by screensavers, but then you can't use those keys in your other apps.

Ok. Hard coded keyboard bindings .... not good.

But thanks for the info.

Hi Alatun
Don't know if this would work, but what if you commented out the  tty1  line in  /etc/inittab? You would probably need to remaster
to make that change.

you could exit after running Xvesa in the background. then people can switch to vts but can't ctrl-c.

[Alatun]

Thanks for you input guys.

@Rich - I also was thinking about this solution, but removing tty1 from inittab would disable any possibility for console access. This should still be possible for diagnosis.

@hiro - I will try this. This looks like a simple solution for my problem.

Hi!

Any solution for this?

Already disabled tty1 on /etc/inittab, but, hangs on boot.

-nozap option running fine for CTRL + ALT + BACKSPACE and CTRL + ALT + DEL, but i need to disable CTRL + ALT + F1 too.

Xorg is not an option.

Hi brunok
Install  Xlibs.tcz.  Then enter:

Code: [Select]

xmodmap -e "keycode  67 = F1 XF86Switch_VT_2 F1 XF86Switch_VT_2"Now hit:

Code: [Select]

CTRL + ALT + F1and let me know what happens.

Hi Rich,

Not solved. Same issue.

Changes are made, but not solve.

Hi brunok
OK, execute:

Code: [Select]

xmodmap -pkeand post the lines for keycodes 67 and 68.

[brunok]

Done. See attach.

Hi brunok
See if this works:

Code: [Select]

xmodmap -e "keycode  67 = F2 F12"

[brunok]

Hi brunok
See if this works:

Code: [Select]

xmodmap -e "keycode  67 = F2 F12"

YES! 

It's awesome, my custom Thinclient's SO (TinyCore) are finished (fast and secure)! 

Thanks!

Hi brunok
Glad to hear it worked, and thank you for participating in our little game of keycode shuffle.
