我的积分有问题。我的笔记本电脑 MSI Summit 14-Intel IRIS XE 中的显卡。
笔记本电脑上的显示屏工作正常，但如果我将外部显示器插入 HDMI，则无法识别。电缆没问题，因为在 Windows 上可以正常工作。
本地主机:/home/milan # xrandr
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1920 x 1080, current 1920 x 1080, maximum 1920 x 1080
default connected primary 1920x1080+0+0 0mm x 0mm
1920x1080 77.00*
我能做些什么？请问你能帮我吗？
