Graphics and font problem in Ubuntu 14.04 with Intel Broadwell-U Integrated Graphics

14.04 graphics intel-graphics fonts

Solution 1

This solution seems to have partially fixed it for me UBUNTU 14.04 Gui text and pictures displaying problem like a virus

But instead of the following :

Section "Device"
  Identifier  "Intel Graphics"
  Driver      "intel"
  Option      "AccelMethod"  "uxa"
EndSection

I have set the AccelMethod to sna

Indeed, UXA was giving me terrible lag

Solution 2

This looks like a bug in Intel graphics drivers. There is no vivid HWE for trusty yet. So you can do one of these:

Wait till new HWE appears in Ubuntu repositories. It is a matter of a week or two, then upgrade to it. I prefer this.
Install Ubuntu 15.04.
Do 2 + Intel graphics installer. (I do not like this)

My fonts, windows are often affected by graphic distorisions, bugs, sometimes disapear without any reasons.

When I reboot it is generally solved.

This is happening since I update my kernel and graphics, but I don't know how to solve it.

I have a Dell XPS 13 running ubuntu 14.04, with Intel HD5500.

Output of lspci -k | grep VGA -A2

  Please edit your question and add there output of "lspci -k | grep VGA -A2" terminal command.

  It looks like a bug in the newer intel driver.

  Last question. How did you upgrade your kernel and graphics?

This is not a real solution, but a workaround. But workable.

Yes that's what I tought, but still it seems to be working pretty well, less buggy, and graphics are also working faster so I will stick with it until Intel releases a knew driver, as you adviced

For more information on what this actually does, see man 4 intel or wiki.archlinux.org/index.php/Intel_graphics#Troubleshooting. I have seen similar problems with 15.04 on a new laptop with Broadwell Intel Integrated graphics, but as far as I can tell sna mode is used by default - verified through grep -i uxa /var/log/Xorg.0.log from the comments here: cynic.cc/blog/posts/sna_acceleration_vs_uxa
