I notice considerable difference between 1680x1050 and 1920x1200. On Buster, speed doesn't seem to be any issue, but screen tearing is, at least, it is on a 1920x1200 screen. Last I checked, there were many old ATI cards newer and with more RAM than an X300 in the $20 & under price class. It might be a good move for you to take if possible. Normally I don't use an X300, but for purposes of this thread, I pulled an HD8570 temporarily in order to see how an X300 would work in Buster/TDE. # xrandr | egrep 'onnect|creen|\*' | grep -v disconn | sort -r Screen 0: minimum 320 x 200, current 1920 x 1200, maximum 4096 x 4096 DVI-0 connected 1920x1200+0+0 (normal left inverted right x axis y axis) 519mm x 324mm 1920x1200 59.95*+ # inxi -GxxSM System: Host: big31 Kernel: 4.19.0-6-amd64 x86_64 bits: 64 compiler: gcc v: 8.3.0 Desktop: Trinity R14.0.7 tk: Qt 3.5.0 wm: Twin dm: TDM Distro: Debian GNU/Linux 10 (buster) Machine: Type: Desktop Mobo: BIOSTAR model: G31-M7 TE serial: N/A BIOS: American Megatrends v: 080014 date: 02/01/2010 Graphics: Device-1: Advanced Micro Devices [AMD/ATI] RV370 [Radeon X300] driver: radeon v: kernel bus ID: 01:00.0 chip ID: 1002:5b60 Display: x11 server: X.Org 1.20.4 driver: ati,radeon unloaded: modesetting alternate: fbdev,vesa resolution: 1920x1200~60Hz OpenGL: renderer: ATI RV370 v: 2.1 Mesa 18.3.6 direct render: Yes # lspci -v | grep -A15 370 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc.
