[Bug 1507255] Re: Garbled graphics in Wily with Intel GMA4500 chip

 

Xenial looks good testing Ubuntu GNOME 20160218 amd64:

Title:
  Garbled graphics in Wily with Intel GMA4500 chip

Status in One Hundred Papercuts:
  Incomplete
Status in xf86-video-intel:
  New
Status in xserver-xorg-video-intel package in Ubuntu:
  Confirmed

Bug description:
  This affects both Ubuntu GNOME and Ubuntu Wily 20151017.1. The
  graphics are so badly garbled I can only file this bug on an
  unaffected OS where I've held back the update on just that one package
  to about Beta 1 status:

  lance@lance-INTEL-desktop:~$ apt-cache policy xserver-xorg-video-intel
  xserver-xorg-video-intel:
    Installed: 2:2.99.917-1ubuntu1
    Candidate: 2:2.99.917+git20150808-0ubuntu4
    Version table:
       2:2.99.917+git20150808-0ubuntu4 0
          500 http://us.archive.ubuntu.com/ubuntu/ wily/main i386 Packages
   *** 2:2.99.917-1ubuntu1 0
          100 /var/lib/dpkg/status

  I'll attach a picture of the garbled screen with the updated xserver-
  xorg-video-intel package. Oddly a screenshot taken from the affected
  OS displays perfectly OK in the unaffected OS so I used my camera.

  The info provided by lspci may not be very helpful:

  lance@lance-INTEL-desktop:~$ lspci -v -s `lspci | awk '/VGA/{print $1}'`
  00:02.0 VGA compatible controller: Intel Corporation 4 Series Chipset Integrated Graphics Controller (rev 03) (prog-if 00 [VGA controller])
   Subsystem: Intel Corporation Device 0025
   Flags: bus master, fast devsel, latency 0, IRQ 27
   Memory at d0000000 (64-bit, non-prefetchable) [size=4M]
   Memory at c0000000 (64-bit, prefetchable) [size=256M]
   I/O ports at f1c0 [size=8]
   Expansion ROM at <unassigned> [disabled]
   Capabilities: <access denied>
   Kernel driver in use: i915

  The tech specs show:

  Internal Graphics:
  • Intel ® GMA4500 onboard graphics subsystem with support for:
  ― Analog displays (VGA)
  ― Digital displays (DVI-D)

  I'm just using VGA ATM.

  Something else worth mentioning is this warning displayed while filing
  the bug report:

  Your system is providing 3D via software rendering rather than
  hardware rendering.  This is a compatibility mode which should display
  3D graphics properly but the performance may be very poor.  If the
  problem you're reporting is related to graphics performance, your real
  question may be why X didn't use hardware acceleration for your
  system.

  I did try booting an earlier kernel to no avail, but holding back just
  this one update prevents the borkage.
