Public bug reported:
I installed Ubuntu 12.04 alpha 2 amd64 from scratch and suspend is
broken. It was working fine in Ubuntu 11.04.
When choosing to suspend, the process is started, and the PC,
apparently, does suspend for a fraction of a second. Then it resumes
immediately. When displaying the desktop after this process, the
launcher is corrupted, but this is solved by hovering with the mouse
over it.
Also, and maybe related, when the OS is doing the transition between
LightDM and the the Unity desktop, instead of showing a black screen, a
lot of garbage is shown. Sometimes, some textures of windows opened in
the previous sessions are showed.
I also tested Ubuntu 12.04 in another PC, with a notebook with Intel
integrated video card and it suspends and restores fine and no garbage
is shown between LightDM and the desktop.
I am using a Nvidia GeForce GTX550Ti, in a Nvidia-based motherboard
(Nvidia 520 chipset) with a AMD Athlon 64 x2 CPU.
