Created attachment 132582 [det= ails] OS details I have a problem with starting programs that require at least OpenGL 2.1 support. You've been disabled OpenGL 2.1 support in this commit: https://cgit.freedesktop.org/mesa/mesa/commit= /?id=3Da1891da7c865c80d95c450abfc0d2bc49db5f678 with this reasons https://lists.freedesktop.org/archives/mesa-dev/2017-January/1426= 91.html So after graphic drivers update from ppa:oibaf/graphics-drivers repo two mo= nths ago I've got an issue which very similar to this: https://bugs.freedesktop.org/show_bug.= cgi?id=3D100189 . Now this issue is solved, but the current driver package doesn't support OpenGL 2.1 at all. Krita, for example, is one of the best graphics applications that can repla= ce Photoshop for linux. But without OpenGL 2.1 support it has unpleasant incur= able bugs. There are some games like Don't Starve for linux that can't start at = all without OpenGL 2.1 support. The absence of this library it self can not aff= ect the operation of programs in any way by causing a critical failure. Therefo= re, I can not provide a bugreport with a certain segfault for you. But some programs can not work properly without it at all. So I just need to reenable Opengl 2.1 support as it was before. Is there a way to do this? This driver= has a some bugs with OpenGL 2.1 support and it's no longer supported by it's developers, but it's better to use it than not being able to run some progr= ams at all.

Afaict the drirc bits were left so that people can override th=
em based on their
liking. Something like the following should do it.
Do enhance to your liking. Note that separate hunk is needed for each
application.

The method you proposed doesn't work, because the system doesn= 't have a working version of OpenGL 2.1 libraries. See the attachment. I need a version of the drivers in which the OpenGL 2.1 libraries are installed.

Admittedly I'm not expert in i915 code (despite being around a few times) although the suggestion should just work. (In reply to Indie from comment #3<= /a>) > Where can I find them?

Yes I've edited the file /etc/drirc as you said and successfully parsed it = with driconf after adding this lines: <device driver=3D"i915"> <application name=3D"Krita" executable=3D"krita&q= uot;> <option name=3D"fragment_shader" value=3D"tr= ue" /> <option name=3D"stub_occlusion_query" value=3D&qu= ot;true" /> </application> <application name=3D"Don't Starve" executable=3D"= /home/user/GOG Games/Dont Starve/start.sh"> <option name=3D"fragment_shader" value=3D"tr= ue" /> <option name=3D"stub_occlusion_query" value=3D&qu= ot;true" /> </application> None of these programs were launched in the right mode, and they still requ= ire support for OpenGL 2.1.

There's should > be just one libGL.so I apologize for not saying at once, I'm not an experienced Linux user, and I don't know what is in this library and where is it located. But this is wha= t I get using glxinfo | grep OpenGL command in terminal: OpenGL vendor string: Intel Open Source Technology Center OpenGL renderer string: Mesa DRI Intel(R) 945G x86/MMX/SSE2 OpenGL version string: 1.4 Mesa 17.2.0-devel OpenGL extensions: OpenGL ES profile version string: OpenGL ES 2.0 Mesa 17.2.0-devel OpenGL ES profile shading language version string: OpenGL ES GLSL ES 1.0.16 OpenGL ES profile extensions:
Before this ill-fated update, these two programs worked withou= t significant problems. There was one bug when changing the size of application window working with these OpenGL 2.1 graphics libraries. If you change the proport= ions of the window larger than a certain value, then on the sides of this window= the image starts blinking constantly. But it's better to have this bug than not= be able to run these programs at all.
Important information: As far as I can tell, I used to have a = gallium i915 driver installed earlier. But now the developer of this repository has swit= ched to classic version of these drivers. But I'm not so sure in this information because I'm new to these things. Also in the first post, there is a link to the bug that I had. This bug is indicated as belonging to gallium i915g driver. It's also known that this driver is no longer supported. But I need it in the form in which it was be= fore appearance of segfault in i915_dri.so library that's described there: https://bugs.freedesktop.org/show_bug.= cgi?id=3D100189

If you want to see things in action add "glxinfo" as = the binary name and observe the output ;-) I won't object if you really want to address the gallium (i915g) issue, not sure how others will feel. -Emil

Inside this file a lot of things are started. There are Wine, ScummVM and something else. In addition, I wasn't able to run the Krita with support of OpenGL 2.1. Giv= en that it's written there correctly. (In reply to Emil Velikov from comm= ent #8) > No worries. If you want to see things in action = add "glxinfo" as the binary > name and observe the output ;-) However, I was able to run Krita and Don't Starve, using this commands: MESA_GL_VERSION_OVERRIDE=3D2.1 /home/user/GOG\ Games/Dont\ Starve/start.sh MESA_GL_VERSION_OVERRIDE=3D2.1 krita But earlier this game started and worked much faster, using older drivers t= han using this command now.
If I Use this commands there are about one frame per 20-30 sec= onds. Previously, everything worked at a speed of 15-20 frames per second. So using these commands isn't an option.

As I figured out I need not only OpenGL 2.1 drivers support, b= ut also i915 Gallium 2d driver acceleration.
