[Bug 1511727] Re: compiz HIGH CPU usage only during screen is off
** Description changed:
- SOLUTION:
+ I just realized that my problem is NOT screen switch OFF, but the screen lock is ON.
+ Therefore I removed this issue from duplicate.
- 1. Run ccsm (from package compizconfig-settings-manager)
- 2. In OpenGL > Sync To VBlank = OFF
- 3. In Workarounds, enable "Force full screen redraw (buffer swap) on repaint".
- 4. reboot
+ My (updated) problem:
- I made this bug as duplicate, but the bug found there (in ATI driver) is
- NOT TRUE, I have Intel GPU.
+ I got very HIGH CPU usage ONLY when screen lock is ON.
+ Again, I have NO PROBLEM during work (video playback, moving windows slowly or fast, no lag, everything is perfect),
+ BUT when I am out of computer: 20 secs after screen lock activates CPU fan starts and works heavily (my colleague started to complain due to my CPU fan in quiet environment).
+ When I switch off screen lock: compiz works nicely.
+ When I switch on screen lock for 1 min (after display goes off):
+ - My laptop is calm AFTER screen goes off,
+ - Ma laptop's fan starts 1 min 20 secs after screen goes off.
- Original problem:
-
- I got very HIGH CPU usage ONLY when computer going IDLE.
- Again, I have NO PROBLEM during work (video playback, moving windows slowly or fast, no lag, everything is perfect),
- BUT when I am out of computer: 20 secs after display fades out CPU fan starts and works heavily (my colleague started to complain due to my CPU fan in quiet environment).
+ So confirmed: My problem is NOT screen switch OFF, but the screen lock
+ is ON.
