I can start the launcher, log in, hit 'play', then launcher window closes and a new full screen black window opens like it used to, and then nothing. I end up with a black screen and a working mouse pointer.
Have to crlt-tab out of full screen black window switch to another desktop and force close what should be the game in a full screen window.
First let me say my system is definitely a "fringe" configuration that is unsupported by SE but FFXIV has worked flawlessly for the last 2 years, and before that it was running on Steam using Proton as a 'non-steam game'for another 2 years. Version 6.55 was working perfectly using WINE and Lutris on June 25th before the update.
My current system, software (all 64bit);
GNU/Linux, Devuan 5 (Debian 12 fork)
Trinity Desktop Environment 14.0.1.0
Glorious Eggrolls custom WINE package version 8.26 with the Lutris game launcher.
current hardware;
Intel Core i7-8700K CPU @ 3.70GHz
Argus motherboard with 16GB RAM
nvidia GTX 1050, 3GB vRAM, using Linux driver ver. 525.147.05
Also been trying to get FFXIV working on my old system that is mostly the same except with a Intel i5 @ 2.8GHz, 12GB RAM, same vid card, and dual boots between Windows 7 and Devuan 4. Tried getting the game working in Win 7 but was getting some errors about the Visual C++ runtimes. I know SE doesn't support Win 7 anymore but the different OSs handle and report errors differently so its useful for diagnostics and testing.
What I've done so far;
confirmed the new bootFFXIV.cfg and FFXIV.cnf have the same edits as the older working ones, browser 0, browsertype 1.
The update changed it back to the games original 1280x720 windowed default. The same settings you get when you do a clean install. I manually edited the new FFXIV.cfg the update created for borderless window at 1920x1080, 1280x1024, 1280x800, 1280x720.
Installed the latest version of Microsoft's Visual C++ 2015 redistributable, 14.0.24123.0, into both the WINE prefixs and Windows 7.
All told today I reinstalled the games FOUR times, one "Restore game data" from the FFXIV Launcher's config menu, 3 completely clean (2 on Linux, one on Win 7).
So far nothing has worked. I've spent about 14 hours today trying to get the game working, a lot of that was just waiting for the game to (re)install and searching the forums for a solution.
Started a complete reinstall of Devuan 5 and installed the latest nvidia production release driver, 550.90.07 (the 525 is from the default Devuan repositories). Will finish that tomorrow.
Worst case If that fails I'm going to try installing Win 10 on my older system. if I can get to play FFXIV that way then I have to consider is FFXIV is important enough to me to give MS money for a Win 10 lisence. I ditched Windows when 8 came out, hated the UI, I don't like to be spyed on by my OS, and working with it was a major PITA. So many settings that used to be user changeable now weren't. I've also been around long enough to know about most of the less than legal things MS did in the past to get where they are.
The only thing I can solidly say is the issue seems to be centered around the file 'ffxiv_dx11.exe'. Since Linux/WINE handles running programs a little differently than Windows I was able to see how far along in the chain of executing programs FFXIV gets before it dies. the black screen that I was ending up at was ffxiv_dx11.exe not releasing it's display window when the program dies.
Sorry for the long sort of rant/vent. This has been incredibly frustrating, I've been playing for seven years and loved almost every minute of it. Hopefully the info above will be of some use to someone. I'm heading for bed, it has been a very long day trying to deal with this.
UPDATED: Fixed my install. Game now working.
So after getting some sleep and getting my morning caffeine requirement I resumed my search with a general focus on the ffxiv_dx11.exe program. After some digging I broadened my search to black screens and dx11 in general without looking for FFXIV specific issues.
Found a comment about turning the Vulcan shaders on, I kind of skimmed over it since the DVDK option in WINE was already enabled but it made me ask what would happen if I turned Vulcan support OFF. Which I did, and the game started normally. The delay between the game window going full screen and black and the "Square Enix" intro pl;aying was a little longer than usual the screen then went to the Dawntrail game menu and I was able to connect and load my main character. Spent the rest of the day getting caught up with my friends who were already playing. After I get this edit finished I'm going to see about starting a thread with this info to make this info easier to find.
So, tl:dr, try turning Vulcan support OFF. Worked for me, might work for you. YMMV. Good luck.
