      @mitu hi, i tried, as you advice me, information about logs but i can't find strings that i can get as a crash ( i tried also dsmeg for kernel infos ) or no logs at all because of hard reset as i can't bypass on terminal by means of keyoboard shortucts o similar ( also tried to restart X daemon by add new shortcut )then ..As a suggestion in the web i try with snaped edition of retroarch and all go perfectly .. and i don't realize the cause in repository or git complied version of the app for the things goes wrong. there's also other ways to get log information of X or in a hard reset and reboot ? thnx have a nice day

        You can start X from the command line (via xinit) and check the terminal output when the crash occurs. You'll probably need to disable the graphical login manager (lightdm or gdm, I'm not sure what your distribution uses by default) and login on the console command prompt.

          understand but
          -( using linux mint 19 ) the problem i can't see nothing on the terminal also in verbose mode launching emulationstation --verbose because soon as i type it start fullscreen ..there's a mode to go screen reducted !? sorry i'm a totally newbie on this ^_^

          • i don't understand, sorry, if the terminal commands you advise me , are to launch after or before the crash ..cause as i said before i can't exit no-ways to the black screen crash ( X daemon ? ) to a tty terminal also with special combo keys profile saved on the keyboard .. tryin to restart or kill lightdm ..but nothing happened..

            Try to boot to console - https://community.linuxmint.com/tutorial/view/460 - and run start or xinit from the terminal (after you login). Do you get any errors, does the desktop starts ? If no, then start EmulationStation as you normally do. If the X session crashes (as you say), then you'll be back at the text console, where you should see some errors related to the crash.

              @mitu thank a lot for the advise but it's funny to say ... tryin to modify the grub boot cfg file at the shotdown reboot i can't go directly to tty mode but it booting and continue black screen ( like the text mode do with no starting mint logo ) but it relove at the lightdm log in.
              sorry could i made procedures error in some ways !?

                The procedure might be incomplete. Sorry, I don't have Linux Mint so I can't offer more insight into this. Try disabling the lightdm service and see if you boot to text mode. If not, try to find out what login manager you're using and maybe disable that.

                    good evening
                    as you can see i reach the text mode and effectively emulationstation doesn't start without log error then.. tryin to launch X an error occured:
                    Xcrashlog
                    And i also notice that then i return on lightdm the resolution of the desk change, same way when i had to reboot as retropie freeze all desktp.
                    I don't know now how to proceed to fix errors.
                    thnx always a lot for your support

                      I don't see a fatal error in the XServer log, the only error logged is

                      [   358.487] (EE) open /dev/fb0: Permission denied

                      which is from fbdev video driver, not used here since it loads the AMD driver. The end says:

                      [   359.133] (II) Server terminated successfully (0). Closing log file.

                        Good evening,
                        sorry but i can't resolve nothing in text mode; emulationstation can't run for his errors:
                        error initializing SDL, No avaible video devices, Render failed to initialize , windows failed to initialize. Seem's like X is NOT active but i launch it... i don't know how to do further ..

                          @hagakure72 in the meantime from google i search for this error i find there's the problem running from lv 3 text.. they proposed to launch from boot and add this line from the grub : systemd.unit=multi-user.target so launch startx or xinit
                          is this correct !?

                            No, it's not correct - EmulationStation (and RetroPie) does not use a desktop session/X.org to function and it's not a supported configuration.

                                @hagakure72 I still don't get what/where the exact crash is - your X session seems fine, maybe an emulator 'crash' can be found in /dev/shm/runcommand.log ?

                                  @mitu when the crash happen, i hard reset then restart the system as i can't get a tty in a freeze status.. so i go like you suggest me to get log from /dev/shm/runcommand.olg but i can't find nothing. infact as sometime get no crash i find there the log without error as a list the operation in the retropie like type of emulator rom launched etc. so crash without log or log without crash.
                                  i can't go further..infact i can't understand what happened different when one time things go perfect ( sometime i change the kernel ... but second chances to run other rom all crash so i think is not depending on this ) i don't know if depend on using a particular type of emulator : neo geo or version of mame and i don't know, it's own configuration ( video settings, audio .. ) but i can't get log after crash ... so i dont know to proceed to fix. have a nice day and thnx for all the detailed reply.
