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:
** 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. ======================================================= glmark2 2017.07 ======================================================= OpenGL Information GL_VENDOR: VMware, Inc. GL_RENDERER: llvmpipe (LLVM 5.0, 256 bits) GL_VERSION: 3.0 Mesa 17.3.3 ======================================================= glmark2 Score: 207 =======================================================
Now, I happened to have a Linux Mint 18.3 xfce Live USB around, so I booted with that, and ran glmark2
======================================================= glmark2 2014.03+git20150611.fa71af2d ======================================================= OpenGL Information GL_VENDOR: Intel Open Source Technology Center GL_RENDERER: Mesa DRI Intel(R) HD Graphics 5500 (Broadwell GT2) GL_VERSION: 3.0 Mesa 17.0.7 ======================================================= glmark2 Score: 1583 =======================================================
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.
