Switching from SNA to UXA downgrade 2D day-to-day performances as SNA is the not-so-new default acceleration method for recent Intel graphics card (as in my case Broadwell HD 5500). More info about performances here : http://www.phoronix.com/scan.php?page=article&item=intel_2dxorg30_ubuntu1404&num=1
For example, at startup, the only icon folder on my desktop is now displayed slowly with UXA rather than SNA. However as Luke #32 said before this is better to have this workaround than missing letters problem, but it's only a workaround, not a real solution. @girisha #35: forget about xf86-video-intel, your xorg.log show you have Intel driver : 3.831] (II) intel(0): Using Kernel Mode Setting driver: i915, version 1.6.0 20080730 [ 3.831] (II) intel(0): SNA compiled: xserver-xorg-video-intel 2:2.99.914-1~exp1ubuntu4.2 (Maarten Lankhorst <maarten.lankho...@ubuntu.com>) In any case, try to create the following folder: sudo mkdir /etc/X11/xorg.conf.d/ Then create inside the new folder a file named for example "20-intel.conf" with the following content: Section "Device" Identifier "Card0" Driver "Intel" Option "AccelMethod" "uxa" EndSection Then reboot and voila. If something goes wrong (if X server failed for example), you just have to delete the 20-intel.conf to revert back. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1432194 Title: Graphics unstable on Ubuntu 14.04 and 14.10 using Intel HD Graphics 5500 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1432194/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
