Reported Version: v0.2.1 (latest) | Mods: none | Can replicate without mods? Yes OS: Pop! OS Linux (Freedesktop SDK 23.08 (Flatpak runtime) (64 bit)) | CPU: AMD Ryzen 7 3800X 8-Core Processor | GPU: NVIDIA Corporation NVIDIA GeForce RTX 2070 SUPER/PCIe/SSE2 | RAM: 15934 Mb There was a prior bug report: I discovered I was having the same issue as this prior postor using Linux, but the solution the threat ended on did not work for me. I did not have to enable any other options; Proton version is 8.0-5. Sounds like this may be a Linux-specific problem?

Can confirm. I used CKAN to disable all outdated mods (KAC is nominally up to date) and it was precisely the resize cursor icon that killed the cursor. Still haven't confirmed if this is a mod or base game bug, but I think we're hunting this problem down.

So here's a fun one. I use basic mods: KAC, KER, MechJeb 2, Chatterer, and [x] Science. I think they've finally caught up to version 1.4, but now I'm hitting a really weird glitch. When I do something to cause a new window to pop up in my game's interface, my mouse cursor will sometimes and unpredictably disappear. This has happened while modifying Kerbal Alarm Clock windows or even just mousing over the base game icons (like the mission button) to cause a window to pop up. The only way I can get the cursor back is to restart the game. I'm running KSP in Linux/Steam using an Ubuntu-based OS. I've tried verifying the local game files but so far that hasn't fixed the problem. Anyone have any ideas? Thanks!

Well I... damn... I spent a while reading that thread and trying to make sense of it--I'm pretty new to Linux, and I'm running Mint exactly because I want a slow easing-in to the more in-depth issues. Then I re-read your comment about the unity prefs file and the solution was ridiculously obvious: <unity_prefs version_major="1" version_minor="1"> <pref name="Screenmanager Is Fullscreen mode" type="int">0</pref> <pref name="Screenmanager Resolution Height" type="int">900</pref> <pref name="Screenmanager Resolution Width" type="int">1</pref> <pref name="UnityGraphicsQuality" type="int">5</pref> <pref name="UnitySelectMonitor" type="int">-1</pref> </unity_prefs> Something about the disaster-crash set the resolution width to 1. I wish I were making that up. I changed fullscreen to 1 and width to 1600 and lo and behold, the game launches! Thank you so much for mentioning the prefs file. (If anyone else comes across this, it's in ~/.config/unity3d/Squad/Kerbal Space Program) After reading through the massive bugs, I'm blown away that the fix could be this simple. In fact, I'm still half-afraid that it was another coincidence, but I'll report in again if this bug resurfaces in a way that fixing the prefs file can't fix.

Well, this has been an interesting couple of days in my computer troubleshooting world. Since last time (since my Mint distro is fairly new), I just backed up my saves and reformatted my Linux partition. This restored my ability to open steam by using the command "LD_PRELOAD='/usr/$LIB/libstdc++.so.6 /usr/$LIB/libgcc_s.so.1 /usr/$LIB/libxcb.so.1 /usr/$LIB/libgpg-error.so' /usr/bin/steam" (This was my previous status quo because AMD drivers don't play nice with Steam). KSP installed and ran fine. I then tried CKAN (installed fine) and put on KER and Alarm Clock. Ran fine. However, I figured out what I believe to be the root cause of the crash, and it seems to be related to the graphics: I have two monitors, and I often drag KSP to my second monitor to play. Cinnamon (that's part of the Linux Mint GUI, I believe) crashes consistently when I try to move monitors. So now my problem has changed from "I may have modded my game into oblivion" to "My computer can't handle the graphics!" It's still an issue I am trying to fix. After a couple of attempts to move the window, I'm back to the tragic position of being unable to open the game and getting the same error message. Answering the questions so far: No. It invariably gives me the same crash report in Player.log. my kernel appears to be 4.4.0-21-generic, according to the uname -r command.

Thanks for your input. I did install libcurl4-openssl-dev before installing mono, and I got the new cert-sync tool. My version of mono is 4.2.1, so I'm above that requirement. Since my last message, I even tried using my Linux Mint installation disc to repair the entire OS install, install steam again, and then at long last re-install KSP. Still getting the same libraries in the error message. Short of formatting my entire hard disk, I'm not sure how to fix this problem--or if reformatting would even fix it. I turned on more advanced debugging, so the most recent error message follows: Stacktrace: Native stacktrace: /home/cersad/.steam/steamapps/common/Kerbal Space Program/KSP_Data/Mono/x86/libmono.so(+0x89917) [0xf42f0917] /home/cersad/.steam/steamapps/common/Kerbal Space Program/KSP_Data/Mono/x86/libmono.so(+0x21a63) [0xf4288a63] [0xf7746bd0] /usr/lib/i386-linux-gnu/libLLVM-3.8.so.1(_ZNSt8_Rb_treeIjSt4pairIKjjESt10_Select1stIS2_ESt4lessIjESaIS2_EE8_M_eraseEPSt13_Rb_tree_nodeIS2_E+0x23) [0xefb762d3] /usr/lib/i386-linux-gnu/libLLVM-3.8.so.1(+0x15c532c) [0xf0bac32c] /lib/i386-linux-gnu/libc.so.6(+0x2e993) [0xf719b993] /lib/i386-linux-gnu/libc.so.6(+0x2e9ef) [0xf719b9ef] /lib/i386-linux-gnu/libc.so.6(__libc_start_main+0x103) [0xf7185643] /home/cersad/.steam/steamapps/common/Kerbal Space Program/KSP.x86() [0x80955c9] Debug info from gdb: ERROR: ld.so: object '/home/cersad/.steam/ubuntu12_32/gameoverlayrenderer.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS32): ignored.

I had a fairly brutal bug happen when I tried to use CKAN to add the Kerbal Alarm Clock mod. KSP crashed on loading once (at the SQUAD screen) and since then refuses to start. The crash actually made Cinnamon (my Linux-based OS) crash as well. I am using Linux Mint 18 Cinnamon 64-bit and running KSP through Steam. I tried deleting/reinstalling CKAN, deleting/reinstalling KSP, apt-get install --reinstall commands for both steam and mono-complete, so far I can't even get a vanilla install back. I also turned off the Steam overlay in case that was causing problems. Ran a full update of all the packages associated with ubuntu/linux mint. No dice. My player.log output reads as follows (my user name is put in for my Linux user name in the folder paths): Stacktrace: Native stacktrace: /home/cersad/.local/share/Steam/steamapps/common/Kerbal Space Program/KSP_Data/Mono/x86_64/libmono.so(+0x91a46) [0x7f5583620a46] /home/cersad/.local/share/Steam/steamapps/common/Kerbal Space Program/KSP_Data/Mono/x86_64/libmono.so(+0x348e4) [0x7f55835c38e4] /lib/x86_64-linux-gnu/libpthread.so.0(+0x11390) [0x7f558a0fb390] /usr/lib/x86_64-linux-gnu/libLLVM-3.8.so.1(_ZNSt8_Rb_treeIjSt4pairIKjjESt10_Select1stIS2_ESt4lessIjESaIS2_EE8_M_eraseEPSt13_Rb_tree_nodeIS2_E+0x10) [0x7f5579d4e290] /lib/x86_64-linux-gnu/libc.so.6(+0x39ff8) [0x7f55888f1ff8] /lib/x86_64-linux-gnu/libc.so.6(+0x3a045) [0x7f55888f2045] /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xf7) [0x7f55888d8837] /home/cersad/.local/share/Steam/steamapps/common/Kerbal Space Program/KSP.x86_64() [0x46f695] Debug info from gdb: ERROR: ld.so: object '/home/cersad/.local/share/Steam/ubuntu12_32/gameoverlayrenderer.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS32): ignored.

I'm not sure how to fix this error. ___________________________________________________________________________________________________________________________________________________________ EDIT: I have figured out how to replicate the crash. This appears to be an issue with graphics or gameplay stability, the association with CKAN appears to be coincidental.
