Package: gnome-shell Version: 3.30.1-2 Steps to reproduce: 1) Upgrade from Debian stretch (fully patched) to Debian testing (buster). Exact steps taken may be seen as documented in ( https://linuxconfig.org/how-to-upgrade-debian-9-stretch-to-debian-10-buster) 2) shutdown system (/sbin/shutdown now) 3) start system and login 4) open terminal and type start 5) watch gnome-shell take 42-105% utilization continuously 6) watch mouse cursor be VERY laggy if usable 7) Open new terminal try and type - watch some lag in keystroke display with occasional multiple characters being displayed on single keystroke.
The system/desktop in general is so laggy that it is unusable. Have performed fresh installs of Debian 9 and upgraded using same steps a couple of times in order to try and further isolate and make as vanilla as possible. suggested fix: unknown workaround: boot into buster init 3 and then startx. booting straight into gui (init 5) is where the issue is noted. hardware details: Dell T130 - will provide detailed specs if needed StarTech.com KVM providing USB only switching for keyboard/mouse for this use(does not seem to impact) (model SV231DPDDUA) Keyboard: Microsoft Comfort Curve 2000 Mouse: Logitech MouseMan Wheel
