On some monitors an "Input Signal Out Of Range" error occurs a bit after the grub menu due to resolution issues. The fix is simply requiring vga kernel parameters be changed for both xen and dom0.
For xcp-ng version 8.2 and below, only following the steps in Citrix Article CTX226191 are required.
For xcp-ng v8.3b, modprobe.blacklist=i915 parameter needs to be added to dom0 along with the above fixes as the module is no longer blacklisted by default.
- Edit: @stormi pointed out module is blacklisted in modprobe.d by default. On Beta2 my systems do not appear to be loading the module anymore.
I'm planning to make a PR to the troubleshooting documentation in order to fully document and explain the above process along with how to do it temporarily at boot (mainly needed for installations) but I'm not sure when I'll get to it at this time so figured I'd get the information posted here if anyone wants to write it up.
