Re: [Touch-packages] [Bug 1645891] Re: After adding a second monitor, mouse pointer flickers and/or disappears in a zone near the top of first (notebook) monitor, while some apps show slow in ext disp
Hello team / Christopher, One more interesting finding, which points towards Compiz + GLX + nouveau: 1. The glxgears works fine on first monitor (60 fps or more) but very slow on secondary. Actually, the speed is "obvious": exactly 1 fps ! This happens only if the whole window is on the secondary. If even a tiny fraction of the window remains on first monitor (even just a single pixel), the speed is normal. 2. When glxgears or glxheads runs on first monitor, the mouse-dissappearing-zone is clear and stable: No mouse pointer between 1/8 and 3/8 of the screen from top. This happens regardless of where the glxgear windows is placed (in 1st monitor). It also happens if only a tiny fraction of the window remains on first monitor (even just a single pixel), while the rest is in secondary. 3. When glxgears or glxheads runs on second monitor, the pointer flickers in the mouse-dissappearing-zone, however, it remains mainly visible. I found some older chats blaming the nouveau drivers for X-org. However, the nvidia does not work for me (no second monitor at all), so could not check.

Hello Christopher, In some recent tests: a. It occurs with monitor connected either on the laptop's HDMI, or the docking stations HDMI. b. In one case monitor is VGA (with converter), in the other it is HDMI. c. I have no access to other type, for the moment. d. I have not disabled the card, but I have used it only with power supply, so perfromance profile should be enabled. e. The nvidia proprietary does not work correctly. It causes a lot of issues, including image corruption and freezing of all when suspending. Also, it does not properly drive the externral monitor. f. I will try to check with the image you mentioned. However, the problem seems to exist since quite some time. My system is fully updated to the most current modification. g. The flickering on basic monitor changes with what windows are open. For example, it is always worse when evolution is maximized there. Some times it goes away if I open a gedit write some few lines and then mark them using the mouse. Sometimes it just needs few clicks within the flickering area or even just leaving the cursor there for few seconds. h. For the external monitor issue, the two programs that suffer most are HipChat and Viber. Both are fine if one part resides on the standard monitor. Michael Στις 12.01.2017 07:16, Christopher M.
