Tôi có hai con chuột, một con có vấn đề trong đó nút chuột giữa và nút6 được kích hoạt đồng thời. Vì vậy, tôi cấu hình của tôi ~/.Xmodmap
để vô hiệu hóa nút này. Tuy nhiên, đồng thời, tôi muốn vẫn có thể sử dụng nút này với con chuột khác của tôi. Vì vậy, tôi đã viết một udev
quy tắc được gọi là xmodmap
thay đổi bố cục nút tùy thuộc vào con chuột nào được kết nối.
Thiết lập
Đây là thiết lập hiện tại của tôi:
/etc/udev/rules.d/logitech-g7.rules :
# deactivate MB 6 when mouse 1 is connected
ACTION=="add", ENV{DEVTYPE}=="usb_device", ENV{ID_VENDOR_ID}=="046d", ENV{ID_MODEL_ID}=="c51a", RUN+="/home/user/.scripts/Troubleshooting/Bugfixes/mouseswitcher_wrapper 1", OWNER="user"
# restore defaults when mouse 1 is disconnected
ACTION=="remove", ENV{DEVTYPE}=="usb_device", ENV{ID_VENDOR_ID}=="046d", ENV{ID_MODEL_ID}=="c51a", RUN+="/home/user/.scripts/Troubleshooting/Bugfixes/mouseswitcher_wrapper 0", OWNER="user"
/home/user/.scripts/Troubledhoot/Bugfixes/meddwitcher_wrapper :
#!/bin/bash
/home/user/.scripts/Troubleshooting/Bugfixes/mouseswitcher "$1"&
/home/user/.scripts/Troubledhoot/Bugfixes/meddwitcher
#!/bin/bash
sleep 1
DISPLAY=":0.0"
HOME=/home/user/
XAUTHORITY=$HOME/.Xauthority
export DISPLAY XAUTHORITY HOME
if [[ "$1" == 1 ]] #differentiate between ADD (1) event and REMOVE (0) event
then
/usr/bin/xmodmap /home/user/.XmodmapG7 > /dev/null 2>&1
else
/usr/bin/xmodmap /home/user/.Xmodmap > /dev/null 2>&1
fi
Nếu đường nối này hơi phức tạp một chút thì đó chỉ là do tôi vấp phải một số vấn đề với udev, xmodmap và biến HIỂN THỊ. Kịch bản của tôi dựa trên Q & A này .
Tình trạng hiện tại
Hành động THÊM hoạt động tốt, hành động XÓA không. Thực hiện một trong hai lệnh RUN bằng tay trong một thiết bị đầu cuối hoạt động tốt.
Những gì tôi đã cố gắng cho đến nay
Tôi tìm thấy bài đăng diễn đàn này nêu rõ lý do tại sao udev có vấn đề với các hành động loại bỏ và theo đó thay thế ATTRS bằng các biến ENV. Nhưng tất cả những điều này đều vô ích, trình kích hoạt XÓA vẫn không hoạt động.
Có điều gì đó tôi đang làm sai. Tôi thực sự sẽ đánh giá cao nó nếu ai đó quanh đây thông thạo hơn về udev và Linux nói chung có thể xem xét trường hợp của tôi.
