【问题描述】:
我已将带 HDMI 和 USB 的 Iiyama T1731SR-W1 17" 触摸屏连接到我完全更新的 Raspberry Pi 上。触摸无法即插即用,我花了几个小时试图让它工作。

dmesg 给出错误,但我不确定它是否与

所以我认为设备已被正确识别,但当我触摸屏幕时光标没有移动。我一直在尝试使用 xinput_calibrator 校准屏幕,但此工具也无法识别触摸事件。
我正在使用内核 4.9.59-v7+
请帮忙
【问题讨论】:
-
先试试
sudo rpi-update;sudo apt-get update; sudo apt-get upgrade再试试……看来是驱动改版有问题?! ...或更好地按照制造商手册进行安装 -
我忘了告诉我我已经这样做了:)。以下制造商自动安装驱动程序也不起作用
-
我的是
Linux 4.9.70-v7+,那么你必须至少做sudo rpi-update然后重新启动并再次检查 -
上面写着
Your firmware is already up to date -
您是在 rpi3 上使用 NOOBS 还是 Raspbian ... 还是其他...? NOOBS 有很多问题...我已更改为 raspbian,并且在低级设备管理上修复了许多问题...例如 USB 挂起和 UART 同步等
