xtrlock is a simple tool to lock your desktop.
Most common way to lock our desktop is to use a screensaver based locking, where a screensaver (may be blank) will run and prompt for password when keyboard or mouse is activated.While desktop is locked, no window will be visible.
What distinguishes xtrlock is its simplicity. With xtrlock the screen is simply locked, all windows that were visible will still be viewable. Only a small lock icon will be displayed. This is handy in many situations.e.g Often while trouble shooting network lines in my centre I wil be inside a bunch of cables away from monitor. I wish ping/netstat runs and someone tells me the status while I am attending. Normally we need to leave the session unlocked for this – which is not desirable. However, with xtrlock the ping/netstat output is continuously on display, still the screen is locked. Anybody can view the output.
On the downside following features are not implemented – timeouts, mouse cursors, locking of devices other than keyboard and mouse.
