Default Bug#572754: linux-image-2.6.33-2-amd64: Xorg / virtual console switching glitch with KMS on i915

Package: linux-2.6
Version: 2.6.32-8
Severity: normal

While I am currently running 2.6.33-2, I also have this problem with
2.6.32-8. The issue is that when I switch from Xorg to a virtual
console, wait some seconds and then switch back to Xorg, for about 0.5
seconds I see what was on the screen before I switched away from Xorg,
then the screen flashes and gets updated by Xorg. Usually when it gets
updated the screensaver has kicked in. I would expect that when
switching back to Xorg I'd see the screensaver instead of a flash of my
desktop. I also wonder if this could be a minor information disclosure
security issue. As you can see below, I have an i915-based Intel GPU,
which defaults to using KMS. I didn't have this issue before i915 was
switched to using KMS by default.

This happens to me too, on 2.6.32 and 2.6.33, with a Radeon X800GT and a
Radeon HD 4650 (both using KMS).
