    Update time. I still get the freezes sometimes (usually in the next hours after running certain 3D games) and am almost certain the problems are because of the fglrx driver. It's a bad driver... but until the radeon one can run games the same way I have to bare with it.

    I managed to make it stop when restoring minimized Konsole windows at least. That quit causing freezes and crashes after I went to Configure Desktop -> Desktop Effects -> Advanced and set "Keep window thumbnails" to Always and "Scale Method" to smooth. I believe this makes desktop effects no longer cause the problem themselves, so I just need to be careful with games.

    Interesting thread. I'm also suffering from intermittent and apparently random freezes on opensuse 12.2 (desktop effects on and using default radeon drivers with a Radeon 6750). Come back to computer in morning/after work and find it won't respond to mouse or keyboard, cannot SSH to it and no display on monitor. After some hours wasted thinking it was a faulty RAM problem due to memtest reporting spurious errors (see https://bugzilla.novell.com/show_bug.cgi?id=773569, I did not read the 12.2 release notes) I've come back to the conclusion that it's a software problem causing my freezes. I've not seen anything in any of the /var/log/ Xorg or messages or ~/.xession-errors to give me any clues though.

    As when the freeze occurs I lose the display (monitor reports nothing from DVI cable, on other hard freezes/crashes I expect the display to stay stuck) it may well be down to desktop effects. I did have crash problems when Kwin was enabled on earlier versions of opensuse, different crash results though. I was kind of expecting that desktop effects problems would have been ironed out by now.

    I'll see how I go with desktop effects turned off.

    I really have the expectation that my PC will only reboot following power cuts (I don't have a UPS), or when I want to do a hardware change or opensuse upgrade. Have had uptime of > 150 days a couple of times before, at least one of those on my current hardware (one new Intel SSD 330 excepted).

    At this day there are barely any more slowdowns, crashes and freezes for me. Likely thanks to updates fixing them over time, as well as me tweaking desktop effects to reduce such issues. But I know the source of what caused 95% of the problems; The fglrx driver. I hope in 12.3 the open-source Radeon driver will be able to run games, so I can finally get rid of fglrx and all its issues.

    Years ago I had random crashes or lockouts when coming back to my
    computer after some time. The culprit turned out to be the screensaver.
    It was set to choose one randomly each time, and some of them locked the
    machine hard.

    I discovered by running some of those screensavers directly from the
    selection screen. Nowdays I never set a random one. I choose one that
    uses little CPU (and little GPU too), or a black screen.

    to me, black screen is the _only_ "screen saver" that make any
    sense...why, because it is the one which uses the least energy..

    anyway, who has a TV with dancing blinking swirling stuff going on
    when no one is there to enjoy it??

    and, the screens of last century (Cathode Ray Tubes [CRT] displays
    actually) *needed* a "screen saver"...whats in use today do not..

    ymmv

    Hi,

    Just a thought.

    What's the size of your file /var/log/journal/<32bit#>/system.journal?

    cheers

    With that criteria, yes :-)

    I have it running for a few minutes only, then dpms mode kicks in. Some
    times you can configure to require a password to get back in after
    sleep, not after screensaver phase, and that's a convenience for me. I
    hate when I'm staring at the screen and saving mode kicks in suddenly
    and I have to type my password.

    Ah, you have not worked at an office where there is some competition to
    have the cutest screensaver running ;-)

    I'm not so sure of that. I have seen modern displays with burn in, at
    kiosks or banks displays, where the thing is displaying the exact same
    thing for days. I'm not absolutely sure of the technology they used, though.

    I am experiencing the same.
    I have recently installed OpenSuse 12.3, KDE 4.10 on both my desktop and laptop. The two architectures are quite different:
    - Desktop, 64 bit, home built system, geforce 610 card
    - Laptop 32 bit, HP G61, HP integrated video card

    Since my first installation of OpenSuse 12.3 on the desktop I started experiencing random system freezes: image frozen, no response from either mouse or keyboard, no possibility to switch to console mode, the desktop can not be reached via ssh from the lan.
    These freezes happen every few days and typically while logged in and browsing the internet, but not necessarily.

    My first instinct was to blame the hardware so:
    - I replaced the PSU
    - I replaced the geforce card
    - I was almost in the process of replacing the motherboard when suddenly....

    It happened on my laptop too! And I just had upgraded OpenSuse from 11.4 to 12.3!
    So it has to be a software problem.

    Like many other users, trawling thorough logs (messages and Xorg.0.log) did not help.

    I guess it will work eventually when disabling desktop effects.

    A bit disappointed that KDE team seems to be chasing the latest glitzy things while forgetting about stability.
    Similar bad experience with Nepomuk and Akonadi with a previous upgrade (12.1), and which finally and thankfully seem more stable now.

    Upgraded? Which procedure:

    Online upgrade
    method
    Offline
    upgrade method


    Chapter 16. Upgrading the System and System Changes


    openSUSE 12.3 Release Notes
    ?

    Hi

    Updated by zypper dup after changing the repos from 11.4 to 12.3 following the instruction somewhere on this forum.

    In a nutshell, the system is fine and usable, much more stable on laptop than on desktop.
    I like the latest KDE but feel there is still some instability in OpenGL
    I only had one freeze on laptop and about 10 in few weeks on the desktop.
    The freezes are unrecoverable (power off/on only remedy) as described in this thread.

    Thanks
