    Default openSUSE-12.2 x86_64 KDE completely unusable - hangs / freezes

    Hi,

    I'm new to Linux so please forgive me if I am being stupid but I have installed openSUSE 12.2 using the openSUSE-12.2-DVD-x86_64.iso image. I verified the file using MD5 checksum, installed it to a partition on a 2 TB SATA drive as part of a multiboot system that includes Windows 7, PC-BSD and Debian, in addition to openSUSE. The graphical installation suggested using the same swap file as I had configured for Debian (Debian is installed on a separate 160GB ATA drive) so I went along with that.

    The first time I logged into KDE everything was a little slow and then it would freeze completely. Not knowing the Ctrl-Alt-Backspace shortcut I had to do a hard restart using the power button when this happened. After the second time I did some googling and came to the conclusion that it might be because of my graphics card (on-board nVidia - C61 - GeForce 7025 / nForce 630a) so I used the one-click installation method for the nVidia drivers that I found on this page: SDB:NVIDIA drivers - openSUSE (the top button).

    After installing the drivers and rebooting I had even worse problems if anything. Clicking on the application launcher button resulted in a 10 to 15 second wait for the menu to appear and then if I tried to click on applications, it would just hang, doing nothing. Being a little wiser this time, I logged out of the desktop and logged into lxde, (which works fine). I wondered if I was still having problems because I had installed 32-bit drivers instead of 64-bit drivers (I noticed the nVidia files all had 32-bit in the file name when they were downloading) so I tracked down the NVIDIA-Linux-x86_64-304.43.run file and downloaded it. I then had a steep learning curve which ended with me stopping the x server and installing the drivers from the command prompt. After a few false starts owing to the fact that I had not installed gcc, make and kernel-devel, I eventually succeeded.

    Unfortunately, the KDE environment is still completely unusable for me so I am at a loss as to know what to do next (apart from not using it of course!). I don't have a cutting edge PC but I would have thought it was powerful enough to run KDE. I have 8GB RAM and an AMD Athlon II X2 250 3.0 GHz and it has run every other OS I have tried without problems like this.

    The only alteration I made to the desktop on my first boot was to close the widget thing in the top left hand side of the screen (which I couldn't work out how to open again afterwards). I can't see how this could be relevant but I thought I'd better mention it.

    If anybody has read this far without falling asleep I'd really appreciate some pointers as to what else I can try or a heads-up if my hardware is simply not up to the task.

    Sorry, I almost forgot to add - when I view system information by typing "sysinfo:/" into konqueror, I noticed that it reports my CPU as being 800 MHz, 1800 MHz or 3000 MHz at various different times. I don't know if this is normal behaviour / relevant or not?

    Many Thanks

    Mark

    so I tracked down the NVIDIA-Linux-x86_64-304.43.run file
    It is probably easier just to use the openSUSE rpms, though you might have to manually uninstall the .run file drivers. I think just run the install again with the --uninstall parameter. But I haven't had nvidia for four years now.

    After a few false starts owing to the fact that I had not installed gcc, make and kernel-devel, I eventually succeeded.
    If you have the will to figure all that out we can probably solve this.

    This is normal when cpu frequency scaling is enabled, which it is by default. It should probably not be the cause of the problem.

    Ok first of all; I would try disabling desktop effects with shift+alt+f12. If that does not improve performance, I would ensure you are using the raster backend for qt applications. The easiest way to do this is to install the kde control centre module for it. Using one click install: http://software.opensuse.org/ymp/KDE...graphicssystem

    Set it to "raster" and log out and back in. That is all I can think of to try at the moment.

    Thanks very much for your reply. It's 1.20 am here (in Thailand) so I'll try your suggestions in the morning and see how I get on. I hope I have something positive to report back then!

    Thanks again for your time.

    Actually I couldn't resist one more go before I turned in for the night. I disabled desktop effects using the short-cut you suggested and everything was fine. I then installed the control centre module and it was already set to raster when I opened the Qt Graphics System module. What has got me puzzled is I re-enabled desktop effects after that (using the same short-cut - it seems to have worked) and everything is still working great!

    I need to reboot now and see if it all works from the start or if I have to disable and then re-enable desktop effects every time. I don't really understand why it's working now to be honest but thanks very much for your help.

    Re. uninstalling the drivers that I installed using the .run file.. I just looked in YaST2 and they are showing as being an installed package there - does that mean that they are OK to keep?

    I'm not sure if I have too many drivers installed though - I still have the nouveau drivers installed and several for nVidia:
    libdrim_nouveau1, nvidia-computerG02, nvidia-gfxG02-kmp-desktop, x-11-video-nvidiaG02, xf86-video-nv and xorg-x11-driver-video-nouveau. I also installed oyranos-monitor-nvidia when I was flailing around earlier.

    I realise all those file names may not mean a lot to you if you no longer use nvidia cards but do you know why the version number for one of them would appear in blue in YaST2, instead of black like all the others? (it's the xf86-video-nv one, which is an "NVIDIA driver for the Xorg server")

    Cheers

    Sorry to keep replying to my own thread, I don't seem to be able to find an edit button for previous posts....

    Anyway, I rebooted into KDE and everything was hanging again, no icons were appearing and my background wallpaper didn't appear. Disabled desktop effects and re-enabled them again and everything works fine once more. I am no nearer to finding a permanent solution but at least I have a workaround for now.

    Cheers

    I would be sure the nvidia drivers are correctly installed, by forcing them to reinstall. Also, you might want to look at the desktop effect settings and make sure it is not using xrender, and turning the scale method to smooth.

    To gather more debugging info, get to a terminal by opening konsole. Then you will be able to view logs using the less command. You can also try installing ksystemlog. Here is an example to view the xorg log.
    Code:
    less /var/log/Xorg.0.log
    You can use pastebin or suse paste to paste a link to it here for someone to help debug. I hope you get some answers.

    Well, I looked at desktop settings and compositing was already set to OpenGL, so I didn't change anything there. I did change the scale method from accurate to smooth though but it didn't make any difference to the problems I am having when logging into KDE. I then uninstalled all the nvidia drivers using YaST and my installation is now back to the state it was when I first logged in. It isn't freezing completely (well not during the time I was using it) but the windows are very slow when dragging them and it's obvious something is wrong (this is using the nouveau drivers with desktop effects turned on).

    I am a bit confused as to what to do next.

    I'm not sure what you mean by "forcing" the nvidia drivers to reinstall? I haven't been prompted to install them as of yet. I have looked at the drivers available using YaSt and I'm not sure which one/s to use.There are three kernel module drivers for geforce 6 + cards: nvidia-gfxG02-kmp-default, nvidia-gfxG02-kmp-desktop and nvidia-gfxG02-kmp-pae. the first two are 36.6 MB and they look the same to me but the third one is 27.3 MB (they all have the same version number).

    Then there is the x11-video-nvidiaG02 driver, which is 151.1 MB in size and has a similar but not identical version number. Maybe if I try to install one I will find that it is dependant on one or more of the others.. I'm a little reticent to start installing drivers willy-nilly again though as it didn't work out great the first time! Additionally nvidia-settings and libxnvCtrl are available for install, both of which are said to be for configuring the Nvidia-Linux Graphics Driver - not sure if these are relevant or not.

    A bit more information that probably isn't relevant. Although I have set my time zone to Bangkok, the clock adds 7 hours to the current time here rather than to UTC time. When I changed the actual time and rebooted into Windows my clock there was 6 hours slow! Also the Apper application doesn't seem to be able to load properly, I just get a spinning circle whenever I try to view updates there (although I have already updated the system using YaST - I had to stop the Apper service (sorry I have forgotten the name - packageKit?) when I wanted to use YaST though and I have to do this using the terminal command: kill [process id].

    I fully understand if you are bored rigid with my problems by now but any advice re. which drivers to install next would be much appreciated.

    Many Thanks

    Apper is broken. Maybe it has broken down your system. Use YaST online update or zypper instead. From my experience it's best to actually uninstall apper.

    As an addition to the great advice you already received posting the output of this command will show us your repositories :
    Code:
    zypper lr -d
    Best regards,

    At the moment I'm tempted to try re-installing the 64-bit NVidia drivers the "hard way", which is what it looks like I did originally. However, I didn't do everything that is listed in the guide to do this (which I have subsequently found) such as using this command after install: "modprobe nvidia" and blacklisting nouveau drivers / preventing them from starting at initrd

    Actually I cannot follow the "hard way" instructions completely because there is no /boot/grub/menu.lst file in my system that I can see...
