I don't understand how this bug can be 'invalid', when it perfectly describes the symptoms on my fresh Ubuntu 14.10 installation. It's discouraging to see that all commenters' effort to help identifing the cause of the problem is dismissed with 'this is not a me-too bug'.
@Timo Can you reopen #1385764 please, it cannot be a duplicate of an 'invalid' bug. -- 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/1386721 Title: Graphics Slow After Upgrade 14.04 - 14.10 Status in xorg package in Ubuntu: Invalid Bug description: Using Gnome Ubuntu 14.10, Dell XPS 13, intel 915 Graphics After upgrading from 14.04 to 14.10 there are a lot of places where the graphics are working much slower than they were before: - Gnome Shell Interface is very sluggish, visible "chops" (redrawing) when pressing the [Super] key. - Selecting text in Gedit takes a full second pr. line Experiences some subjective improvement when I booted kernel 3.13.0-37 instead of 3.16.0-23, but that may be my imagination as the problem persists. I've searched google, forums, found a couple of relevant links that point to the issue being the Intel drivers. http://askubuntu.com/questions/53962...E2%86%92-14-10 http://www.webupd8.org/2014/10/ubunt...ent-1652086424 But the drivers currently in 14.10 should be newer than those supplied by Intel to 14.04 so that doesn't make sense to me. As one Intel developer wrote: "I would like to point out that since what we do is bring more ecent versions of the software to the target distributions than they ship with, a 14.04 targeted installer is unlikely to bring much to a 14.10 installation, which most likely has the same or more recent versions already anyway."
