[Ubuntu-x-swat] [Bug 1803681] Re: osmesa doesn't suport core contexts but could
indeed, it was enabled fairly recently: mesa (18.3.0~rc5-1) experimental; urgency=medium * New upstream release candidate. * rules: Fix a typo in list of dri drivers. * rules, meson-add-glx-direct-toggle.diff: Fix build on hurd. * rules: Drop extra -Dosmesa from confflags. * rules: Don't build gallium nouveau on s390x. * rules: Classic osmesa needs classic swrast, and since it's not enabled where llvmpipe is enabled, enable gallium osmesa there. -- Timo Aaltonen Fri, 30 Nov 2018 11:45:45 +0200 so, disco has it, and it's also on ppa:ubuntu-x-swat/updates bionic will get it with 19.0.x backport for 18.04.3 ** Changed in: mesa (Ubuntu) Status: Incomplete => Fix Released -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1803681 Title: osmesa doesn't suport core contexts but could To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/1803681/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

Fully patched 64-bit Ubuntu 18.04LTS Intel I7 AMD Radeon HD 7950 open-source drivers. Is this fixed in 18.10 or 19.04? And did you try the test program? And looking at https://packages.ubuntu.com/bionic/libs/libosmesa6, I don't see the dependency on llvm. -- Greg On Thu, Mar 14, 2019, 01:50 Timo Aaltonen wrote: > gallium osmesa is already enabled where it's supported, so what's your > platform? > > ** Changed in: mesa (Ubuntu) >Status: New => Incomplete > > -- > You received this bug notification because you are subscribed to the bug > report. > https://bugs.launchpad.net/bugs/1803681 > > Title: > osmesa doesn't suport core contexts but could > > Status in mesa package in Ubuntu: > Incomplete > > Bug description: > If the --enable-osmesa in the mesa configuration were replaced with > --enable-gallium-osmesa, then the OSMesaCreateContextAttribs would be > able to return OpenGL core contexts.

gallium osmesa is already enabled where it's supported, so what's your platform? ** Changed in: mesa (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1803681 Title: osmesa doesn't suport core contexts but could To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/1803681/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
