    Hi there,

    I've been trying to get this to work on Arch, but so far have failed. When I start PA, I get a beautiful black screen and nothing else.

    The following obstacles I've already overcome:
    • Installed an older version of libcurl.
    • Linked libudev.
    I have an HD4870 graphics card and the latest open source drivers. My log is attached. I'm totally stuck, so any help is much appreciated!

    So you don't see main menu? Can you please try to run game from console and then post output here?

    At this moment game log doesn't include Coherent debug output.

    I'm trying to get the log here, but for some reason uploads don't seem to work, links to dropbox I'm not allowed to post and the log is to long for a single post... Give me a moment.

    I split the log in three posts. I don't really like the triple-post, but considering the way this forum works I don't see another way, sorry!

    You can post link fine if you replace "http://", "www." and "." with something else.

    PS: You can as well remove shader compilation errors from log, they're not related to black screen in menu.

    Also you can try to run PA executable with this parameters:
    Code:
    ./PA --coherent-log-level=TRACE --log-threshold=4
    Then much more info will be included in log.

    I ran it with the longer log, there is three additional lines in there that don't seem that interesting.

    I uploaded the new log to dropbox, which I still can't post even if I obfuscate the link beyond recognition. That software is good, and annoying.

    And to answer your first question: Nope, no menu. Just a black window.

    Yep this is very annoying, still after 5 message it's probably disabled already.

    Can you try to run it with launch options?

    Also can you please try to run PA and then check output of "ps aux | grep Coherent". I just wonder if you have some Coherent crash or just strange issue with VSync.

    PS: I run PA on R600g myself, so it's pretty interesting why it's not work for you.

    So I'm continuing where I left yesterday.

    Anway, the last log was already using the launch options, I believe. To be sure, here is a new one:
    https://www.dropbox.com/s/jivd71moxuls2pz/PA-19-58-56.540.txt

    When starting the game, while looking at my black screen, there is no process called coherent (did a case insensitive search) running.

    Thanks for your help so far!

    It's mean you still have some problems with Coherent. You need to find out why it's fail to start.

    You can play a bit with "/host/CoherentUI_Host" script and check what might cause that.

    I don't know what did it, but I downloaded a newer version today and installed it using a PKGBUILD from the AUR and it works! Now I just have a weird mouse cursor, but I saw plenty of other threads about that around. Thanks for all your help!

    You can check this topic for fix:
    https://forums.uberent.com/threads/...tu-12-04-13-04-13-10.53019/page-2#post-814965

    There also fix for broken shaders and FXAA:
    https://forums.uberent.com/threads/...nux-mesa-and-intel-hd-on-windows-57703.54239/

    Also you can try fixed sun shader for R600g here:
    https://forums.uberent.com/threads/linux-foss-drivers-issues-and-fixes.51007/#post-779846
    But I'm not yet totally sure if this works with 57703.
