This host is running Slackware64_14.2. Yesterday I replaced the Radeon
RX-550 video card and HP/Compaq LA1951g monitor to a Radeon Pro WX-2100
video card and an Acer SB-220Q monitor.

While the Xfce4 resolution is set to 1920x1080 dpi, it keeps resetting to
the former 1280x1024 dpi.

lspci shows no video driver:

I just downloaded amdgpu-install_22.20.50205-1_all.deb and ran it through
deb2tgz. Can I upgradepkg using the amdgpu-install_22.20.50205-1_all.txz?
Or, what do I do to have the monitor hold the set resolution?

Thanks in advance,

Rich
