    Default Mesa OpenGL on Intel HD5500 - Lenovo Z70 laptop

    Hi

    After my trials getting the Tumbleweed USB installer to work with this laptop, I now find that the OpenGL / Mesa performance is really slow.

    This is what glmark2 on Tumbleweed reports:
    Code:
    ** GLX does not support GLX_EXT_swap_control or GLX_MESA_swap_control!
    ** Failed to set swap interval. Results may be bounded above by refresh rate.

    Now, I happened to have a Linux Mint 18.3 xfce Live USB around, so I booted with that, and ran glmark2

    So what do I need to do to get the openSUSE tumbleweed Mesa to give me the same results?

    I don't think I have any packages missing, and on my previous Tumbleweed install on another HDD, I didn't have this problem.

    I don't recall loading the Intel Linux drivers from https://01.org/linuxgraphics to get it working with my previous install

    And to be honest, looking through /var/log/Xorg.0.log it looks as though TW is using the same versions of xf86-video-intel as is on their site


    But there is obviously something wrong.

    NB I've tried building Mesa from source from the 01.org site but at the moment it fails to build - problems with the location of the llvm shared libraries

    But I'd prefer to just use standard drivers out of the normal SUSE repos, if possible.



    Thanks

    Sorry, should have said. I've tried both with, and without, xf86-video-intel installed.

    And I'm using xfce4 as my desktop manager, which is the same that the Linux Mint Live USB I used uses.

    It looks from /var/log/Xorg-.0.log in the Mint live that is also using xf86-video-intel

    lsmod shows modules for i915 running, which is what I would expect.

    Kernel on OpenSUSE is 4.14.15-1-default OpenSUSE xorg.0.log says

    Solved

    I had another look at my /var/log/Xorg.0.log and saw that "nomodeset" was being found on the commandline, which has been leftover from the struggles I had installing Tumbleweed last week.

    Removed that from

    Code:
    /etc/default/grub
    and did

    Code:
     sudo grub2-mkconfig -o /boot/grub2/grub.cfg
    and one reboot later, I've got:

    Sorry about that, I wasn't expecting the install to have appended "nomodeset" to

    Code:
    GRUB_CMDLINE_LINUX_DEFAULT
    and I didn't review it later.
