Save screen report
See a very good screen saver on Linux, the picture keeps the transformation, so I want to save the screenshot screen.
1. Find another machine, SSH.
2. The pause and continuation of the screensaver screen, that is, the pause and continuation of the screensaver process
Kill -s STOP process ID
Kill -s Cont process ID
Info kill can see more signals
3. Screenshot: CAT / DEV / FB> file name
Re-display: CAT file name> / dev / fb
4. As for how to save the screenshot file into a picture file format, then find a way, such as using Ksnapshot.
