Public bug reported: Hello!
First of all: thank you so much for your work! I have been using Unity/Compiz for a couple of years now and have been very happy with this software. Thank you for making this possible for so many people. God bless you for that! I have since a couple of weeks a multi-monitor configuration like this: - Monitor A: laptop internal monitor - Monitor B: external monitor connected directly to the laptop - Monitor C: external monitor connected to a USB-DVI adapter which is connected to the laptop The hardware is: - Intel HD3000 in the laptop - HP NL571AA USB-to-DVI adapter using a Displaylink chip My problem is this: - Show video on C --> CPU usage of Displaylink driver is high - Show video on monitor A or B --> CPU usage of Displaylink driver is equally high Expected behaviour: - CPU usage of Displaylink driver is not high when monitor C is connected and is showing only static content If I disable the compiz OpenGL plugin using ccsm the CPU load of the Displaylink driver is almost zero if I don't use monitor C, as expected. The problem is of course I then can't drag windows anymore so the desktop is becomes unusable. According to this post http://displaylink.org/forum/showpost.php?p=79485&postcount=6 this issue is known by Displaylink and has to be solved somewhere else. My question is: could/should this be solved in compiz? If so, I would be willing to help with the programming if I can. ** Affects: compiz (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of compiz packagers, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/1616981 Title: Using OpenGL with a Displaylink-Adapter leads to high CPU usage To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/1616981/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~compiz Post to : [email protected] Unsubscribe : https://launchpad.net/~compiz More help : https://help.launchpad.net/ListHelp
