Thread: KDE Live CD 11.4 X86-64 graphics performance

  1. #1

    Default KDE Live CD 11.4 X86-64 graphics performance

    I have an 11.2 laptop and thought it was time to upgrade to 11.4. I downloaded the 11.4 X86-64 live cd and thought that I would check how it ran on my 11.3 desktop. This is a core i5 760 with an Nvidia GT240 graphics card and 4GB of DDR3 ram. The 11.4 live system shows the nouveau driver. The graphics performance is terrible. In particular windows are very very slow to resize and often don't resize properly. There are also some artifacts in some graphics. I eventually downloaded Flash which did seem to work moderately well, especially in full screen mode. The screen resolution is 1920x1080. I have never seen a windowing system work so slowly

    While I always use the Nvidia proprietary driver, I don't know how I can test it via a live CD. The Nvidia driver in the repository is the 270 version and I think that I have seen reports of severe problems with the 270 version so that needs to be tested too. I always install the nvidia driver the really easy way via yast

    Has anyone any idea why the KDE Live graphics are so slow? I will not go anywhere near 11.4 unless the graphics system is very much faster. Is there any way to test the nvidia proprietary graphics driver without installing 11.4?

    Can you confirm you do not have hybrid graphics ? ie what is output of:
    Code:
    /sbin/lspci -nnk | grep VGA -A3
    Note wrt openSUSE-11.4, when you boot the liveCD with nVida graphic hardware (not with Intel) it will attempt to boot with kernel modesetting enabled and the 'nouveau' driver.

    If instead, at the liveCD's grub boot menu, you enter the boot code 'nomodeset' then the liveCD will attempt to boot with kernel modesetting disabled and the 'nv' graphic driver.

    I have a desktop with a core i7 920 CPU and a nVidia GTX-260 graphic card, and it works well with the proprietary nVidia graphic driver (currently I'm using the 270.41.06 version).

    Reference KDE graphics being slow, there is also KDE is slow for dummies (don't shoot the messenger) : KDE is slow – for dummies ... but I have not had to use that.

    It may be difficult as it is necessary to black list the nouveau driver and also ensure modesetting is disabled.

    You could try.

    Do this by booting the liveCD with 'nomodeset' in the grub menu . Then in the KDE GUI, blacklist the 'nouveau' driver by typing 'su' (to get root permissions and use < enter > as the passord) and then backlist nouveau in the /etc/modprobe.d/50-blacklist.conf file with:
    Code:
    echo "blacklist nouveau" >> /etc/modprobe.d/50-blacklist.conf
    Then go to yast > System > /etc/sysconfig Editor > System > Kernel > NO_KMS_IN_INITRD and change it to "yes". This takes a minute or two to save once changed is submitted. And it may be wasted effort since the kernel is already booted and running.

    Then download the priorietary nVidia driver to your /home/your username directory. I think the 270.41.19 may be the latest version today (it is in the process of changing as I type this). I will use the "NVIDIA-Linux-x86_64-270.41.06.run" for my example.

    Then type 'su' (use < enter > as the password) and install kernel-source, kernel-syms, gcc and make with:
    Code:
    zypper in kernel-source kernel-syms gcc make
    Don't !!! install via YaST for this.

    Then while you still have root permissions type:
    Code:
     init 3
    and login to this full screen mode as user "linux" and use < enter > as the password.

    Then type 'su' to get root permissions (use < enter > as the password) and then build the proprietary driver with :
    Code:
    sh NVIDIA-Linux-x86_64-270.41.06.run -q
    and after that is complete, type 'exit' to get rid of root permissions, and then try to start X with
    Code:
    init 5
    ...
    It may not work because you did not boot with nomodesetting in the /etc/sysconfig nor with nouveau blacklisted, but its worth a shot.

    Your laptop needs LOTS of memory for the above. Likely a minimum of 4GB of RAM.

    I never tried this with a live cd, but it should be possible to install the
    nvidia driver into the live system. Another way would be if you create with
    suse studio your own live cd which has the nvidia driver.

    Another option, if you have the unused space on a hard disk, and are reasonably comfortable with partitioning, is to resize one partition to give perhaps 10GB free space and install 11.4 there creating only a '/' partition for it, a separate '/home' is not needed as this is only for testing. Later you can either delete the partition and resize, or use it as a data partition until you want to test another version.

    You would need to back up your date first. This is a precaution that should always be taken.

    This allows for a direct comparison between the two installs, means that you should have at least one openSUSE usable while you make the changes, and allows you to sort out any problems at your leisure.

    There was one thing that I forgot as I do it automatically with 11.3 & Nvidia, I booted with nomodeset. If I did not use nomodeset on the 11.3 live cd , the screen would periodically freeze. I tried 11.4 without nomodeset and the slowness goes away. The above output is from the machine booted with nomodeset.

    I thought that nomodeset brought in nv, I may be wrong, but this does not seem to have happened here as the system information screen says nouveau & swrast. There is a log message about NVIDIA not being found

    I am happy not to use nomodeset when I boot from the CD but should it work? Resizing windows is virtually unusable when booted with nomodeset.

    I think that I shall try to build my own live cd with the nvidia driver included as well as dar. I have been intending to build a recovery CD or DVD that includes dar to avoid keeping dar on a usb stick.

    I shall now go and pick a few more Kg of cherries.

    I recommend you double check that.

    We have 3 PCs in our apartment with different nVidia hardware and at least one openSUSE-11.4 install in a partition on each of those PCs (with this nVidia hardware) on these 3 different pcs:
    • GeForce FX5200
    • GeForce GTX 260
    • GeForce G210


    and in EACH case when booting from an openSUSE-11.4 liveCD, using the boot code 'nv' brings up the 'nv' and NOT the 'nouveau' video driver.

    Ergo, I am suspicious of an inaccuracy here. Maybe you typed 'nomodeset' wrong ?

    The following copied from the system information window
    Code:
    Vendor:  nVidia Corporation
      Model:
      2D driver:  nouveau
      3D driver:  swrast (No 3D Acceleration) (7.10))
    Have I got it wrong and if so how does putting in an invalid option make resizing the windows so slow? I would have thought that a miskeyed nomodeset would be the same as no nomodeset at all i.e. nouveau. No nomodeset works
