hi I tried to start on linux blender on an old laptop that mounts a radeon hd 2600 XT with 512 mb video ram but blender crash on startup.
on ubuntu 18.04 second glxinfo with the latest mesa drivers in development is this card supports opengl 3.3 and shading language 3.3

@Clément Foucault (fclem) I think that 'working with --debug-gpu, crashing without it is already known issue?

thanks now I understand the motivation of this imperfection, even if it is a bit of a pity that the effect is not obtained in the correct way
Well the "show backside" has a performance cost associated to it, and it is unnecessary for certain objects (think a simple glass plane).
"bug1" ok in additive and multiplicative works correctly.
so in "alpha blend" a correct display of all the refracted textured faces with "show backside" is not possible ??
at the moment is inverted, the back textured face are shown first..
I'm a bit confused what is the use of the option "show backside" for alpha blend if the correct result is not obtained?
Hehe, has been done since ages…
Awesome, this fixed it for me (trying 77e1942e0e1).
Thanks a lot!

@Clément Foucault (fclem) Yep, this solves the crash here. UI draws normally, and Spring files can be loaded.
The basic visualization for modeling and matcaps is going well, the problem continues in this date when you apply materials.
Thanks Clément. I have this issue in a Microsoft Surface 4, i5 with 4Gb RAM. The GPU is an Intel HD Graphics 520.
Hope it helps :)
I don't have access to a computer that can reproduce the issue but I will in a few weeks.
I remember this was working on previous builds of 2.8 so I think it's not drivers.
@Clément Foucault (fclem) tagging you here just in case, but imho that’s clearly driver issue, we cannot really keep hundreds of tasks opened on things we cannot do anything about, so will archive. Thanks for the report anyway.
The lighting is different in these display modes, and in the Rendered display mode it's very dim so it uses just the start of the ramp.
if enabled "screen space reflection" and or "Ambient occlusion" works, but not always sometimes I have to activate both functions sometimes only one is enough and the SSS starts working again, but if I switch off both Amblient occlusion and screen space reflection SSS it will not work again

Pretty much everything appears to have been converted, any more issue we discover can be handled in their own tasks.
This seems to happen once in a while on some systems, but I can't repro. Debug build is next possible thing to get more info:
I read correctly, understood wrong. I'll build OSD sample app soon and will upload it. =)
- OS : Linux-x86_64 manjaro (arch base), Blender : see report, GPU nvidia GTX1070 with nvidia driver 390.77 (last)
- the system is uptodate
- --factory-startup : crash again
- ogl tweak : ?
- tweak GPU settings : done, i have the performance slider. All positions crash
- blender-softwaregl : console replay : Warning! GLX_ARB_create_context not available.
@Clément Foucault (fclem) almost certainly does not depend on the blend file, the same file on linux on the same gpu works ..
in general the SSS never works on this gpu on windows the drivers are also the last ones that amd has updated at the end of 2015
@Arto Kitula (akitula) There was a misunderstanding.
For switching Intel vs AMD/Nvidia (on dual GPU systems) you can use gfxCardStatus But as said on irc, we're updating libraries, and that OpenSubdiv problem should be solved.
Ok so making sense of the error messages:
@amon paike (amonpaike) I cannot reproduce from scratch. Please share a simple blendfile.
- Give us your exact Blender, OS and GPU (including drivers) versions, as requested in the template!
- Ensure both your OS and drivers are fully up-to-date (and use official GPU drivers, not those provided by windows or tablet/laptop maker or open source ones in linux distributions).
- Try to start Blender in factory settings (--factory-startup commandline option) (this will ensure whether this is a userpref or addon issue or not).
- Try to tweak OGL settings in UserPreferences, System tab.
- Try to tweak your GPU driver settings (e.g. try different values between 'performance' and 'quality' if you have such slider, etc.).
- Attach as text file here the report generated by Help -> System Info (do not paste it directly in comment).
- Launch Blender from the command line with --debug-gpu option and attach as text file here any error printed out in the console (do not paste it directly in comment).
Please follow our submission template and guidelines, also read these tips about bug reports, and make a complete, valid bug report, with required info, precise description of the issue (only ONE issue per report!), precise steps to reproduce it, small and simple .blend and/or other files to do so if needed, etc.

I can repro it crashes with the following message
Warning! GLX_ARB_create_context not available.
so is a bug right.
