    Negative. I took reverse dependencies lookup on ubuntu 14.04 and only discovered 2 users of libllvm: various MESA parts from Oibaf PPA and clang itself. No other packages were dependent on libllvm 3.4. AFAIK, Webkit uses its own JIT which haves nothing to do with llvm.

    By default, only libLLVM has a versioned name. The headers and other libs do not. Perhaps Ubuntu patches this in, I don't know.
    Ubuntu separates binaries and headers. Headers are in -dev packages and -dev package for llvm 3.5 is different one that 3.4. So they can coexist for sure. Not sure about 3.4.1 but I guess it just should replace all 3.4 stuff alltogether.

      Hi Kmod,
      good idea about partition backup. I decided to just backup my home directory and upgrade to Linux Mint 17. The current Driver I am using is what comes from the install.
      I do not think I will try this "mod" again, until I can feel sure that I will not have to revisit the problem I had.

      Thanks again for replying, I hope the best for you and hope the oibat will be able to make the driver useful again for Ubuntu and Linux Mint.

            • I added llvm 3.4.2 to the 14.04 PPA, OpenGL 3.3 should be supported on more radeon cards now.

              • I use a 7870 (Pitcairn) with Xubuntu 14.04 and still stuck with GL3.1.

                Is it just not yet supported on my HW even with LLVM 3.4.2? Or can I somehow get it to run 3.3?

                Code:
                glxinfo |grep OpenGL

                  You didn't properly install the driver from the PPA. You should see something like (git-xxxxx trusty-oibaf-ppa) in the OpenGL vendor string.

                  • Fount it! Was an xorg-edger ppa what wasn't removed cleanly.

                    I shall feast in OpenGL features now!

                        Woot, thanks! This one makes RadeonSI to support GL 3.3. Though when it comes to heavy 3D loads or OpenCL, it still full of bugs. But there is nothing more you can do about it I guess.

                          How did you find out? And how did you remove it cleanly? I have the same problem (glxinfo says I only have opengl 3.0 and no "oibaf" in the vendor line) and think a former xorg-edgers ppa could also be the cause. I already made a ppa-purge with xorg-edgers and oibaf, reinstalled oibaf ppa... but things still go wrong.

                          For example I can't start steam with the oibaf ppa anymore. The system hardlocks instantly when I try to do this. Unigine valley also doesn't start anymore - not even overriding the opengl-version doesn't help here.

                          • I've tried to use the PPA a few times these days but encountered a few issues with the current version of Mesa 10.3 (ATI RadeonHD 7770 GPU):
                            - in XCOM Enemy Unknown a few days ago, random and complete system freeze (whith the game still running, with choppy sound and computer completely unresponsive − had to make a hard reset)
                            - in Civilization V today, the game crashed randomly (might have been linked with the fact that Steam displayed a message for a trading card, as the crash happened just after)
                            And a few problems of graphic garbage on the desktop and Steam interface, in specific zones. Also, the Firefox window completely trashed when opening a terminal window on Unity.

                            It looks like the driver is quite unusable currently. Have people encountered similar bugs in games recently (the XCOM one was pretty naughty)?

                            • Unfortunately, that's just because you've got an AMD card. It's been the case for several years now that the only way you're going to get Windows-comparable performance and stability under Linux in modern titles like the two Firaxis ports you mentioned is when using Intel's open source drivers (available from this PPA), or nVidia's closed-source drivers (available in other sources). AMD is unfortunately stuck somewhere in the middle; their open-source driver is much better than the nVidia equivalent in that it's actually more or less usable for gaming up to a few generations back (last I checked the newest really-recommended video card to use with it was the Radeon HD 4000 series), but their closed-source driver really isn't much better, so you're not going to be able to get an nVidia-comparable or Windows-comparable experience out of that card under Linux anytime soon.

                              There's been talk of AMD porting Mantle over to Linux since their driver stack is in such bad shape currently, but nothing has come of that yet.

                                Bug in XCOM is being worked on by Mesa devs:

                                Those desktop glitches happened after today's update though, hopefully will get sorted soon enough.
