hey u34, so through my first examination of the errors, i don't really notice anything my first thought was to slap `chromium` at the top of my xinitrc and to see what happens (spoiler: it runs) and then i looked at the backtrace something bugged me
Segmentation fault at address 0x20 address 0x20? only a madman with a system so minimalist could achieve that so my second guess: memory could be getting corrupted, or thrown away (i've had this happen to me as a c developer :()
you might want to check that `iHD_drv_video.so` exists, since thats what libva is hinting at more applications could be loaded by systemd, the kernel, bashrc, xinitrc, etc so you may want to check all of those for any additional unwanted applications being loaded (that could be causing your issue) another one of your bets would be to compile xorg yourself & add -g (for debug symbols) onto it & run it under gdb have you made sure you've installed proper video drivers? just my thoughts here that may/may not help ~turret
