Both myself and @Qvedo have experienced issues with x11 seg faulting after installing Octodash on a system - see [their post for a screen shot of the issue](https://forums.pimoroni.com/t/hyperpixel-4-with-raspberry-pi-5/23873/15)

after i posted a copy of the log that x11 spat out i tried adding `/usr/share/X11/xorg.conf.d/90-monitor.conf` file to include:

```auto
Section "Monitor"
    Identifier "DPI-1"
    Option "Rotate" "left"
EndSection

```

as per this [github post](https://github.com/UnchartedBull/OctoDash/issues/3881#issuecomment-1722254202) but that did change or improve the situation.

@Qvedo’s problem doesn’t seem to mention anything about seg faulting; there’s an error message saying “octodash not found” so I’m guessing he’s not got it set up right.

Your log doesn’t really show anything (other than x11 starting up and then shutting straight back down), which _may_ also be the same problem - you don’t show your output - but also doesn’t indicate any sort of seg fault.

The rotate config stuff is just about … configuring the rotation and would be unlikely to solve either problem.

So, the question is - what makes you think that you have a seg fault, or have you got _precisely_ the same issue as @Qvedo (i.e. a message clearly saying “octodash not found”) in which case… how have you installed octodash, because I’m guessing that’s where you’re tripping up.
