Alt+Print Screen not working (Ubuntu 10.10)

PrintE-mail

Q. I've installed the new version of Ubuntu 10.10 (Maverick) and Alt+PrtScn doesn't work anymore.

A. This will be fixed in the future releases (hopefully), for now there are various ways around it:

1. In terminal window, type in the following as root:

sysctl -w kernel.sysrq=0

This will disable "SysRq" key, which seems to interfere with the Alt+PrtScn.

If the setting disappears after reboot, add it to /etc/rc.local.

2. Print Screen on its own works - you can use that instead if you wish.

Update: I have no idea when this will be fixed - I just assume that it would be fixed in the future releases.

Open /etc/sysctl.conf as root:

sudo gedit /etc/sysctl.conf

Then add this line to it:

kernel.sysrq=0
Or you could change the shortcut

I just re-assigned the "Take screenshot of a window" action to Ctrl+PrtSc in the Keyboard Shortcuts app (in System -> Preferences).

This is because if the system gets into a funny state I like to be able to use the magic sysrq keys available to sync and umount the disks before powering off.
Perfect
