Title:
Unity-2d not working on KVM with xen and cirrus video devices
To manage notifications
I should mention that my previous comment about 16bit depth was while
testing the cirrus graphics card emulation.
The version of the X server incremented recently causing a minor change
in xdpyinfo output. Attached is a current copy of xdpyinfo from
KVM/Qemu guest running with cirrus graphics
When my KVM/Qemu VM guest is run with cirrus graphics emulation in
24-bit color depth mode none of the screenshots attached to this ticket
look like what I'm seeing.
The attached screenshot shows the unity-2d-launcher icons are displayed
correctly but it overlaps the menubar at the upper left
I was able to set 16bit depth.
In /etc/lightdm/lightdm.conf I appended
xserver-command=X -depth 16
no quotes.
Things appear much better now. The status bar in the upper right now
displays all the icons and gadgets, before it was just blank.
The workspace switcher displays correctly.

Here is more information:
I used these 2 applications from qt4-demos
* /usr/lib/qt4/examples/effects/fademessage/fademessage
* /usr/lib/qt4/examples/effects/blurpicker/blurpicker
kvm + cirrus (24-bit color / 24 bits per pixel)
graphicsystem | native| raster | opengl | opengl (mesa
Another version of my tests, since it is unreadable in launchpad:
blurpicker + native - ok
blurpicker + raster - garbage
blurpicker + opengl - garbage
blurpicker + opengl (mesa git/master) - ok
fademessage + native - red/blue inverted
fademessage + raster - garbage
fademessage + opengl - garbage
I'm using Kubuntu 11.04 and am getting some really similar glitches with normal
(effects-enabled) KDE (not 100% reproducably, though). 24bpp is a really common
value for all the machines I used in the last 8 years (X has been
auto-detecting this for years). This is physical machines I'm talking
Reini,
I just want to be sure were talking about the same thing,
color depth and bits_per_pixels are not the same.
On kvm + cirrus, this command give :
pim@pim-virt-pc1:~$ xdpyinfo | grep depth 24
depth 24, bits_per_pixel 24, scanline_pad 32
pim@pim-virt-pc1:~$
And on all machines I have
I see. That must have to do with the part I failed to understand.
My mistake.

Title:
Unity-2d not
I have made some investigations, and I have almost found the bug.
* The X server has chosen a format with 24 bit depth and 24 bits_per_pixel,
which seems
pretty unusual.
(source is qt/src/gui/image/qnativeimage.cpp)
* QNativeImage::format() returns either 16 or 32 bits, but never 24!

Unity-2d not working on KVM with xen and cirrus video
This bug is independent from 791133
(https://bugs.launchpad.net/ubuntu/+source/qt4-x11/+bug/791133).
Bug 791133 is a bug in mesa (opengl) and unity-2d uses the raster graphics
system.

Title:
Unity-2d not working on KVM with xen and cirrus video
I can confirm that cirrus is busted and that vmvga works well with
unity-2d. What I saw with the cirrus driver is similar to what I would
see with konqueror in a vm, so this might be a qt bug.

Subscribing the ubuntu-security team, since we use kvm extensively for
testing VMs, and not having unity-2d as a fallback for unity 3d is a
significant issue.
