Description Mark Nowiasz 2009-02-26 19:04:34 UTC
After updating via emerge -u --deep @world @system KDE's screensaver fails to stop running - therefore locking you out of your system until kill the session (for example, by pressing ctrl+alt+backspace). No matter if you move the mouse or press a key (at one time, pressing a function key like F5 did work), the screensave keeps running. Also doesn't matter which module I select - all of them block the screen.

Reproducible: Always

Steps to Reproduce:
1. Start the screensaver (either manually or wait)
2. The screensaver starts
3. The screensaver won't release the screen

Comment 1 Mark Nowiasz 2009-02-26 19:13:06 UTC
This might be a problem relating to evdev - I remember that evdev was one of the packages being updated and my keyboard and mouse are being managed by evdev.

I *can't* verify it here

> I *can't* verify it here

It "works" reliably here :-/ I just have to test a screensaver and I got locked out :-/

Another strange thing I've noticed: when the screensaver is running, the mouse pointer is visible - I can move the mouse around, but that doesn't do a thing. Occasionally it was possible by switching to a virtual terminal (by using ctrl+alt+f1) and back to X again to stop the screensaver, but I'm unable to duplicate this - right now, there's no combination of keys which stops the screensaver.

Well, it's not (as I though) evdev related - downgrading to 2.1.2 doesn't help.

Oh, one of the packages that got upgraded (and is remotely X related) is nvidia-drivers (from 180.29 to 180.35). Plus I've configured the driver to disable the powermizer (before that, 180.x did freeze my machine occasionally).

I'd be glad to help to find which combination of packages/settings is causing that malfunction, right now I haven't got a clue - only that this behaviour startet after upgrating @world and @system. :-/

Found the culprit - after downgrading to nvidia-drivers-180.29, the screensaver works again. 

OK, this is a duplicate of 260441.
