gnome-screensaver does not reliably allow login after suspend

[Elladan]

Binary package hint: gnome-screensaver

Feisty Beta:

gnome-screensaver doesn't seem to reliably give me a login prompt after sleep. I think the problem may be that it can't get input focus.

Example:
1. suspend laptop.
2. resume.
3. move mouse around, hit keys, etc.

Result:
This often works and gives me a password box I can type in, but sometimes the screen is just black and won't respond to any input.

To work around this problem, I have to break to the console (ctrl-alt-f1). Sometimes just returning to X11 without doing anything else will cause the screensaver unlock to work.

I have a similar problem on Edgy on another machine, which has two monitors: Without a suspend, just locking the screen, gnome-screensaver often never allows me to log in again, and I'm forced to break to the console and kill it. I don't know if the similar problem is actually the same, but I thought I'd mention it as it might be easier to reproduce. Note that I have these two monitors configured as two screens (:0.0, :0.1) and not with xinerama.

Problems with gnome-screensaver unlock are severe, since they cause the machine to appear completely locked up and dead. Most users would consider the machine crashed, and probably power-cycle it.

Thank you for your bug. What videocard and driver do you use? Could be an xorg bug

[Elladan (elladan)]

The machine I have a similar problem with in Edgy uses two video cards:

(--) PCI: (1:0:0) ATI Technologies Inc RV280 [Radeon 9200] rev 1, Mem @ 0xe8000000/27, 0xfe030000/16, I/O @ 0x9000/8
(--) PCI: (1:0:1) ATI Technologies Inc RV280 [Radeon 9200] (Secondary) rev 1, Mem @ 0xe0000000/27, 0xfe020000/16
(--) PCI:*(2:1:0) ATI Technologies Inc Rage XL rev 39, Mem @ 0xfc000000/24, 0xfd024000/12, I/O @ 0xb800/8, BIOS @ 0xfd000000/17

I won't be able to get the actual xorg string out of my laptop with Feisty until tonight, but the hardware specifications for the machine say:
ATI MOBILITY RADEON 9700 Pro (M11-P)

(Using the xorg drivers, not the ATI proprietary drivers)

I have noticed similar behaviour on my machine.

It's a BenQ laptop with Intel 945GM graphics chipset. I'm running Ubuntu Feisty.

It does'n help to restart gnome-screensaver after the problem has occured, it gives the same result every time i lock the screen in gnome, even without making the laptop going into sleep mode.

So far, I have not had this problem with Gutsy. Still keeping an eye out for it.

Hi there
I'm closing this report due your last comment about not being an issue in gutsy, and the fact there isn't any feedback since then.

Thanks
