"journalctl --follow" running during SteamVR start after step 3 (headset
display visible in xrandr)
SUMMARY
I have to re-plug the Valve Index VR headset and then reboot my system every
time I want to use SteamVR
STEPS TO REPRODUCE
1. Start PC - VR Headset is not recognized in xrandr
2. Start SteamVR - get error "Failed to connect to headset display" and SteamVR
is unable to detect the display - same as xrandr
3. Unplug the power connector of the headset and plug it back in after waiting
a few seconds - the headset is now recognized in xrandr
(re-starting SteamVR still yields the same error as before)
4. Reboot PC
5. VR Headset is immediately recognized in xrandr without any replugging
6. SteamVR starts up just fine and I can play VR games.
OBSERVED RESULT
If I did not re-plug the VR headset on the previous boot it is not recognized
on the current boot and even after replugging it it can't be leased until I
reboot.
EXPECTED RESULT
I would expect the VR headset to connect to SteamVR every time and be
"lease-able" after every boot or at least after re-plugging the headset
(without having to reboot).
