Bug#832560: xserver-xorg-core: performance is very bad since using built-in modesetting 4th gen GMA on ivy bridge

2016-07-26 Thread Martin Dosch 
Hello,

after I saw reportbug wasn't able to read the xorg.conf I changed the
permissions to 640 and it works again. It was not mentioned in the
maintainers email that the file requires reading permission for
everyone. So by just copying the file my UMASk set the permission to 640.

But for Ivy Bridge you shouldn't switch away from intel driver as this
was really slowing down my system.

Best regards,
Martin

Bug#832560: xserver-xorg-core: performance is very bad since using built-in modesetting 4th gen GMA on ivy bridge

2016-07-26 Thread Martin Dosch 
Package: xserver-xorg-core
Version: 2:1.18.4-1
Severity: important

Dear Maintainer,

since the last update my systems performance is very low. Even gnome shell
animations like are "stuttering". Playing games is no more possible of cause.

With the update I got this mail:

But this xorg.conf shows no effect after restarting X and even after complete
reboot.
There is also some weird output of VMWare in glxinfo:



> glxinfo | grep OpenGL
> OpenGL vendor string: VMware, Inc.
> OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 3.8, 256 bits)
> OpenGL core profile version string: 3.3 (Core Profile) Mesa 12.0.1
> OpenGL core profile shading language version string: 3.30
> OpenGL core profile context flags: (none)
> OpenGL core profile profile mask: core profile
> OpenGL core profile extensions:

> OpenGL extensions:
> OpenGL ES profile version string: OpenGL ES 3.0 Mesa 12.0.1
> OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.00

Compared to the old output before:

< OpenGL renderer string: Mesa DRI Intel(R) Ivybridge Mobile

Feel free to ask for mor information needed to investigate in this issue.

Bug#832551: xserver-xorg-core: Various X tools stop working with new xserver-xorg-core

2016-07-26 Thread raphael 
Package: xserver-xorg-core
Version: 2:1.18.4-1
Severity: important

Dear Maintainer,

Hi, since yesterday, along with xserver-common and xwayland upgrade, xbindkeys 
stops working with

- W: awesome: xerror:881: X error: request=GrabKey (major 33, minor 0), 
error=BadAccess (10)
- xbacklight -dec 10 gives "No outputs have backlight property"
And maybe others, but haven't seen yet
As neither awesome, xbindkeys or xbacklight have changed, I assume it must be X 
related (even if a libc6 upgrade has happened in the same time).
I'll try to downgrade to see if it's working better
Thanks

Raphael

I updated the patch to work with the current libxcb package, uploaded it
as a NMU versioned 1.11.1-1.1 to DELAYED/15 and attached it to this mail

Update: I tried to force the use of the "intel" X video driver with

  $ cat /etc/X11/xorg.conf 
  Section "Device"
  Identifier "Intel"
  Driver "intel"
  #   Option "AccelMethod" "uxa"
  EndSection

After restarting the X session, I found out that the same issues happen
even with the "intel" X video driver.
Could these issues depend on the kernel upgrade that was performed on
the box along with the xserver-xorg-core upgrade?

  [UPGRADE] linux-image-4.6.0-1-amd64:amd64 4.6.3-1 -> 4.6.4-1

I am Cc-ing the Debian Kernel Team about this.

Dear Kernel Team, should bug #832484 be reassigned to source package
linux/4.6.4-1 ?

Please let me know, thanks for your time.

I am having the same problems on a Lenovo T430, though it is the 3rd gen
hardware. Switching back to the Intel driver fixed them.
