  • Just a heads up, but it seems one of the more recent updates broke shadows on windows with Unity on Ubuntu with my 7850 (the shadows are like sections of a checkerbox). Not sure if anything else is affected or not, or what the cause is.

      Do you know, why do I have horizontal and vertical dancing lines on all versions of open drivers?

      • Seems like there is some new bug:

        https://bugs.freedesktop.org/show_bug.cgi?id=81279

        Perhaps another reason to switch to LLVM3.5 (if it's LLVM issue, which it looks like)? Some of us, less Linux savvy users, rely on your PPA and would love to see it better, so if you need any help (with testing or whatever) just tell us

        Like always though, thanks for maintaining your PPA, it's a life saver for AMD users <3

        • RadeonSI now needs LLVM-3.5 to properly display textures. I figured I'd report it here hoping OIbaf would add it to the PPA+Build Mesa with it. What would be the best way to contact him without a Ubuntu without a Launchpad account, and if I do get a way to contact him. when should I try to take that action?

          Not being able to play any games because if looks pretty terrible is becoming a pain. :P

          • I wonder, can I install LLVM3.5 and use this to rebuild it with LLVM3.5 and if so, is installing LLVM3.5 enough or would it take some more tinkering?

              What you do is you use the git (http://cgit.freedesktop.org/mesa/mesa/) and then use git from the terminal after all installed and do "git clone -b (Branch here, should be "master") (Mesa git URL here)" and then you build the source code like many other programs, be ready to install tons of related programs, it'll tell you, but then you'll build mesa with "./autogen.sh" and then you will see what messages you get, this is how you know what programs to install to be able to compile it. But after it builds, just do "sudo make install" and it should install.

              I've compiled mesa before, at one point I compiled it every day. But, recently I tried to and it installed in 100% wrong directories, so I've never tried it again tbh. Thats why I'm asking it be added to the PPA.

                Considering that I would propably fuck up my system in the process and the fact that issue is gone for now (after today's update), I'll stick with Oibaf PPA

                  Seems fixed now. Might of been related to whatever that LLVM 3.5 thing was, but in any case, all is well currently.

                    A recent commit broke things unless you had LLVM3.5. They reverted part of it, so that LLVM 3.4.2 works again. I don't think anything earlier than 3.4.2 is supported right now.

                    • Any chance for an updated mpv? 0.4.1 was released a couple of days ago

                      Comment


                      • mpv si just a bonus, here. Newer versions require an updated libav, which is too invasive, so i won't backport newer versions.

                        • There is https://launchpad.net/~mc3man/+archive/ubuntu/mpv-tests for mpv.

                          @oibaf: will you move to LLVM 3.5?

                          • Was there a reason why LLVM 3.5 wasn't being used currently (no offense or anything)? Was it just time constraints, or maybe it broke support for other hardware?

                            3.5 seems like it would be pretty useful for radeonsi, and seems like it would fit right in with the already git mesa and xserver drivers.

                            • I must say that I'm quite impressed by the latest performance of the radeonsi driver (oibaf's ppa packages recompiled with llvm 3.5 and linux 3.16, latest rc). Maybe like a month ago Eurotruck simulator 2 was so sloooow and now it performs quite close to what I remember from Catalyst (it's been several months since I last checked that on my dual ubuntu with catalyst). The game feels quite smooth with a Radeon HD 7870 and all settings maxed out at 1920x1080.

                              X-Plane 10 also works quite nicely at 1920x1080 if you launch it with %command% --force_run --no_fbos
                              (Not sure why but without --no_fbos the game prints out a problem with a texture... I'll try to investigate that)

                              So kudos to the radeonsi devs!

                              • Hey. Long time Linux user but new to the desktop stack / Xorg etc...

                                I picked up a new Lenovo Z50 with the AMD A10-7300 Kaveri because I wanted to check out the new HSA features. I installed Ubuntu 14.04 on it and so far everything has gone smoothly (altho I had to boot "nomodeset nolapic").

                                One problem was that X was running with a software renderer so I tried installing the PPA radeonsi drivers but nothing changed. I'm not sure if my problem is that the chip is too new, or if I did something wrong, but since I've never done this before and don't have any understanding about how Xorg/Gallium/PPA all fit together I'm not sure how to debug this.

                                Any guidance would be appreciated.

                                Here's the Xorg.0.log.
