From: Merciadri Luca on 3 Aug 2010 05:00 Hi, I have a random GNOME screensaver, a default one, on this computer (debian Lenny w. kernel 2.6.26-2-686-bigmem). It gets `paused' by pressing Esc, and is `de-paused' by pressing Esc again. Left click does the same effect as pushing Esc, but right click lets me get out of it. I am sometimes unable to get out of it, and I need to restart the X-server, or go to another tty. I'm pretty sure that this behaviour is not normal, and I would like to know what would cause it, and if anybody has ever got the same problems. I looked at the different logs, but found nothing interesting. Most of the time, simply moving the mouse gets me out of the screensaver, but, in other cases, moving the mouse gives nothing, and the situation is the one I describe with Esc and right click. Any ideas? Thanks. -- Merciadri Luca See http://www.student.montefiore.ulg.ac.be/~merciadri/ I use PGP. If there is an incompatibility problem with your mail client, please contact me.

There are some bugs¹ for "gnome-screensaver". Take a look and check if any of them fits into yours. OTOH, you can: 1/ Review your "/var/log/Xorg.0.log" and "~./xsession-errors" 2/ Try with a fixed screensaver 3/ Try with no screensaver at all, just use display power manager options to dim the screen and render it black. And verify if it's still reproducible. Are you using any power saving (suspend to ram or suspend to disk) settings? Are you using VGA proprietary drivers? ¹ http://bugs.debian.org/cgi-bin/pkgreport.cgi?pkg=gnome-screensaver;dist=unstable Greetings, -- Camaleón -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".

There are two sets of drivers and I guess you are using the common one. Standard nvidia driver provides 3D hardware acceleration and people use it mainly for that. >> ¹ >> http://bugs.debian.org/cgi-bin/pkgreport.cgi?pkg=gnome- screensaver;dist=unstable > Checked. Are you using xinerama (nvidia setting for using two displays as just one big desktop) or any other fancy setup for the displays? If yes, you can try to disable (just for testing) and see if you still can reproduce the error :-?

I like plain things that do their job. (That's mainly why I like Debian.) >>> 3/ Try with no screensaver at all, just use display power manager >>> options to dim the screen and render it black. >> Sometimes stalls too.

I have two monitors, with different resolutions, but with a desktop which extends from one monitor to the other one. Some weeks ago, I had tried returning to a plain (i.e. trivial) config for xorg.conf and screens, and the screensaver problem never reappeared. Evidently, I can't stick with one screen, and I need to use xinerama. Speaking about xinerama, I had seen the bug at http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=590121, but my screensaver daemon does not actually crash. It just stalls, but after some time. What's even funnier is that this is just a transitive state, as I've asked Debian to dim the screen after x minutes, where the screensaver comes after y minutes, y < x. As a result, during x-y minutes, the screensaver is displayed. After y minutes, the screen is dimmed, but moving the mouse (or pressing a key) directly redirects me to either a black screen or the screensaver. The fact is that as I'm using a random screensaver, the black screen which I'm sometimes redirected to might simply be the black screensaver (but still a screensaver), as the `dimmed screen' option actually puts my device in sleep mode. That is only once I'm in the screensaver (either after having done something to wake up the screen from dimming, or simply because the screen has not been dimmed yet) that I sometimes can't get out of it. - -- Merciadri Luca See http://www.student.montefiore.ulg.ac.be/~merciadri/ - -- Look on the sunny side of life. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Processed by Mailcrypt 3.5.8 <http://mailcrypt.sourceforge.net/> iEYEARECAAYFAkxYIzgACgkQM0LLzLt8MhwzQwCeP0KEWt8n5x+P3WTWt4htDNTe aagAn0N9exQYAvUH1aXt7jQik4RULjGp =Uvex -----END PGP SIGNATURE----- -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".
