OK, now I'm beggining to understand how this works. Depending on each video card implementation it might require an associated -dri package. Also glxutils will output the current OpenGL version supported depending wether the video card supports it and the required software is installed. If this is the case then this bug is indeed still valid, and now a more important as before, as we can warn users wether they video card with their current setup does supports OepnGL2+ or not. Of course, if I missinterpreted something then please do not hasitate in remarking it :) Thanks in advance, Lisandro. -- 16: De quien es Internet * De DIOS dado que todas las cosas del mundo le pertenecen Damian Nadales http://mx.grulic.org.ar/lurker/message/20080307.141449.a70fb2fc.es.html Lisandro Damián Nicanor Pérez Meyer http://perezmeyer.com.ar/ http://perezmeyer.blogspot.com/ signature.asc Description: This is a digitally signed message part.

Now this alone makes filing this bug worthwhile. Thanks a lot! We clearly need to suggest libgl1-mesa-dri then. -- Lisandro Damián Nicanor Pérez Meyer http://perezmeyer.com.ar/ http://perezmeyer.blogspot.com/ signature.asc Description: This is a digitally signed message part.

It shouldn't, because without libgl1-mesa-dri it should fall back to GLX indirect rendering, which only supports up to OpenGL 1.4. -- Earthling Michel Dänzer | http://www.amd.com Libre software enthusiast | Mesa and X developer signature.asc Description: OpenPGP digital signature

That seems like a > pretty weird implementation choice... That's a good question and yes, it would have been better if it would be checked directly. The fact is that upstream does really not support using Qt with OpenGL less than 2. But Fedora packagers asked for an exception with a patch that checks for an env variable, and as upstream knows that we distros sometimes need to support this kind of setups and they accepted it. Considering the low amount of users with such a setup I don't think it's worth to work on a patch. -- My favourite poem is the one that starts 'Thirty days hath September' because it actually tells you something. -- Groucho Marx Lisandro Damián Nicanor Pérez Meyer http://perezmeyer.com.ar/ http://perezmeyer.blogspot.com/ signature.asc Description: This is a digitally signed message part.

Question: if a user has a video card wich is OpenGL2 or more capable but does not has libgl1-mesa-dri installed: does glxinfo informs "OpenGL version string:" with value 2 or more? This is a very important thing: if this is true then we should maybe recommend libgl1-mesa-dri in libqt5gui5, as Qt heavily relies on OpenGL.

I guess that most users will get it through recommends, but this probably makes the whole excercise futile. Except you happen to have another idea I would say this bug can be closed.

One problem with that is: If libqt5gui5 and mesa-utils aren't the same architecture, what glxinfo reports doesn't necessarily apply to libqt5gui5. For example: glxinfo from mesa-utils:amd64 reports that OpenGL 2 hardware acceleration is working, because libgl1-mesa-dri:amd64 is installed. However, OpenGL 2 hardware acceleration still doesn't work for libqt5gui5:i386, because libgl1-mesa-dri:i386 isn't installed. -- Earthling Michel Dänzer | http://www.amd.com Libre software enthusiast | Mesa and X developer

Package: mesa-utils Version: 8.3.0-1 Severity: wishlist tl;dr: make mesa-utils M-A: allowed in order to be able to depend on it as mesa-utils:any Hi! libqt5gui5 now ships a script in order to detect wether users have an OpenGL2 compatible video card. It case they don't it sets up an environment variable to let Qt now that it should use rasterization instead. The script uses mesa-utils' glxinfo package for this. Problem arises that libqt5gui5 is M-A: same, but ends up depending on mesa-utils:. If mesa-utils gets marked as M-A: allowed then we can make libqt5gui5 depend upon mesa-utils:any, ie, any arch' version of mesa-utils will satisfy the dependency. I would highly appreciate if you can at least reply if you are OK or not with the idea, as we currently have a broken M-A libqt5gui5 and would like to take the necessary steps to solve this.
