VMware Didn’t See My USB Modem — Here’s How I Fixed It (Huawei E3531)

After quite a long time, I recently had to set up an SMS gateway on a virtual server for a customer again.

Koupil jsem si nový monitor s rozlišením 2560×1440 pixelů, ale Xorg ho nerozpoznal korektně xrandr –listmonitors Monitors: 1 0: +*HDMI-1 1920/725×1440/428+0+0 HDMI-1 …takže jsem musel rozlišení nastavit ručně.
