Problems solved by technology

However, at present, in the Linux system, the system itself does not do special processing for the hot plugging of the display. The hot plugging of the display may be due to the inconsistent size of the connected display before and after plugging, and the different supported resolutions. Adapt to the best resolution of the monitor; or because the resolution set before unplugging is lost or exceeds the display range of the monitor, resulting in a black screen and other problems

Abstract

The embodiment of the invention discloses a display hot plug processing method, system and device and a storage medium, and relates to the technical field of display processing. The method comprises:if a hot plug event broadcasted by a kernel is received, acquiring device information of a current hot plug device; traversing a pre-configured display hot plug rule file according to the equipment information, and querying whether a hot plug display processing program matched with the equipment information exists in the display hot plug rule file or not; and if the hot plug display processing program matched with the equipment information exists, calling the hot plug display processing program to display the current hot plug equipment. According to the embodiment of the invention, when the hot plug event occurs, the display resolution of the system can be adaptively switched according to the equipment information of the current hot plug display, so that the problem of various display anomalies caused by the hot plug display is effectively avoided.

Description

technical field [0001] The present invention relates to the technical field of display processing, in particular to a method, system, device and storage medium for display hot swap processing. Background technique [0002] In the scenario where multiple hosts share one monitor, the monitor needs to be switched between different hosts; or, in the scenario where multiple monitors share one host, the same host needs to be switched among multiple monitors for comparison Effect. Whether the display is switched through an adapter or a screen splitter, or the signal line of the display is switched manually by plugging and unplugging the display, these scenarios all involve hot plugging of the display. However, at present, in the Linux system, the system itself does not do special processing for the hot plugging of the display. The hot plugging of the display may be due to the inconsistent size of the connected display before and after plugging, and the different supported resoluti...
