I am one of those i3wm users who have experienced freezes in the past months, which resulted in a downscaling of my QubesOS usage.
Do you think using AwesomeWM or DWM with QubesOS help with this? Do these window managers require the (now commonplace) fix: I3 not working properly video/graphic issues - #4 by bungali
Because if I am understanding you correctly, you suggest that this fix put more pressure on intel CPU with graphics processing, which the old thinkpad x220 CPU has troubles with and freezes.
So, I wonder if using Awesome or DWM wouldn’t require that “fix” and thus would result in no-freezes.
