Known Problems

(and workarounds and possible solutions for them)

PCs don't always shutdown properly when restarting

If it takes a long time for the system to restart, hard reset the PC by holding its power button for some seconds.

Apparently that's a feature of these Dell PCs

Sound cards are sometimes not recognized on cold boot

  • might be fixed by changing BIOS power saving settings ("PCI Express Native Power Management" → Disable or something similar)
  • what we tried: disable ASPM in grub (did not work, might need additional BIOS setting)
  • restarting also works, but the current restart service has permission troubles

SeamLess Plugins don't send out current position

  • Will be fixed in next plugin version, current workaround: changing all relevant automation curves before moving them to the correct settings (urgh)

no network directly after boot causes some services to fail

If a user-service needs network to function make it depend on the special user network online target:

[Unit]
...
After=user-network-online.service
Wants=user-network-online.service

it is also necessary to enable systemd-networkd.service and configure systemd-networkd to manage network interfaces. this is all taken care of by the install_user_network_online_target.yml ansible playbook

reaper session not visible directly after boot

reaper still runs, the UI is just not visible, check the reaper systemd service If you need the UI restart the service

can't access dante device from dante controller, because it is in different subnet

change your ip to a static one in the dante devices subnet, then change its ip to the correct subnet (or, better yet, make it dynamic by enabling DHCP)
