Solve the problem that Alt + PrintScreen screenshot shortcuts cannot be used on Ubuntu10.10.

Since the upgrade to Ubuntu10.10, I have been unable to use the Alt + PrintScreen shortcut, and the shortcut keys in Shutter are completely correct and there is no problem. However, a solution was finally found recently. It was originally caused by the kernel-level MagicSysRqkey, which conflicted with the Alt + PrintScreen shortcut key. The solution is to enter the sudosysctl-wkernel.s in termianl

The solution is to enter

Sudo sysctl-w kernel. sysrq = 0

If it is still valid after boot, add sysctl-w kernel. sysrq = 0 to/etc/rc. local and put it before exit 0. Or Add the following lines to the/etc/sysctl. conf file.

Kernel. sysrq = 0
