Michael Grivas, thank you for reporting this and helping make Ubuntu better.
1) Could you please advise how your monitor and laptop are connected (ex. HDMI, VGA, etc.)? 2) Does using the nvidia proprietary driver change anything regarding this? 3) If you disable the graphics card via your BIOS does this influence this issue? 4) To see if this is already resolved in Ubuntu, could you please test http://cdimage.ubuntu.com/daily-live/current/ and advise to the results? ** Changed in: xorg (Ubuntu) Importance: Undecided => Low ** Changed in: xorg (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1645891 Title: 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 display. Status in xorg package in Ubuntu: Incomplete Bug description: It seems to be duplicate of both : https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1641467 and https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1629300 . Possibly related to https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1278223 A - flickering in first display. The zone starts just below the top panel and its height is about 1/7 of the screen. Flickering starts immediately entering the zone, even half of the pointer may be flickering. To the centre of the zone, flickering is more prevalent, up to completely disappearing. The flickering has a periodic pattern, which seems to be affected by the windows displaying in the second (external) monitor !! B - external monitor. Some applications show really slow there. Worse case is HipChat (Atlassian chat program), which shows fine as long as even a tiny fraction exists on the primary display. At the moment the whole window passes to the secondary, then even the scroll bar has a delay of a second a move. To check, I have played with the ~/.config/monitors.xml without success. It seems that each configuration is saved there, even duplicates, after adding the same external monitor and re-configuring it (absolute duplicate in monitors.xml) C. Side-effects and related phenomena. Some times the "Screen display" control freaks, when enabling the external monitor. It may freeze or insist to put them in mirroring. Most of the times it just forgets a setup (although in monitors.xml) after adding a different external monitor. For each workspace, there is a different background, done with Unit5y Tweak Tool. All updates have been done, without effect.
