[Bug 578979] Re: blank screen after fast-user switch
I tested the daily with qemu, I didn't reproduce it.
I didn't have time to install a daily on my desktop, but as it is a vintage 3 years old but, I think it can be closed.

Title:
blank screen after fast-user switch
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
Binary package hint: gnome-screensaver
This may be a duplicate of https://bugs.launchpad.net/bugs/112518
But it's happening with ubuntu 10.04.
Here's the description.
Log with user A via gdm.
Set the screensaver to 1min (blank screen or whatever).
fast-switch to user B.
wait more than 1 min.
Fast-switch to user A.
=> the screen is blank, no message from gnome-screensaver to unlock. There's only the mouse pointer.
I can still switch to console with ALT-Fx, but the screen is blank (I have to type blinded).
If I restart gdm, the screen is back.
When this happened, I could see via ssh that the gnome-screensaver
process of user A launched gnome-screensaver-dialog process with
argument --enable-switch and --status-message=
I uninstalled gnome-screensaver, made sure its processes were not running and try this:
Log with user A via gdm.
Set the power-manager to switch off the screen after 1 min.
fast-switch to user B.
wait more than 1 min.
Fast-switch to user A.
And the screen was OK.
my video card is ATI Technologies Inc RV710 [Radeon HD 4350]
and I'm using KMS (default lucid configuration).
I'm not using compiz or anything related to visual effects.
package: gnome-screensaver 2.30.0-0ubuntu1
