I've been suffering from this bug in a clean Buster system, too. A solution noted in another bug tracker is to explicitly tell X.org to use the intel driver. Apparently, it uses the fbdev driver by default. (Sorry, I don't have a reference to other bug handy.) Per a suggestion in the other bug, I added the following config about a week ago and haven't seen the problem since. $ cat /etc/X11/xorg.conf.d/20-intel.conf Section "Device" Identifier "Intel Graphics" Driver "intel" EndSection jf -- John Franklin <frank...@sentaidigital.com>
