Package: laptop-mode-tools Version: 1.68-3 Severity: important Tags: patch Dear Maintainer,
laptop-mode-tools is creating a weird bug for usb mouse. After installing laptop-mode-tools and rebooting my laptop, I found that my usb mouse (wired and wireless tested) will be disable after few second of idle. I have to click the mouse button several times in order to activate it back, and it will be disabled again in few seconds. Searching the Internet was proven very hard to find the solution, but I manage to found out the root cause from one of the posting on Internet. It turns out that laptop-mode-tools is aggressively disabling usb port in order to save power, thus disabling usb mouse in the process. The solution to the issue by blacklisting usbhid and psmouse kernel module, restarting laptop-mode-tool, and then replugging my usb mouse. No issue after that. Because usb mouse is quite common, I believe usbhid kernel module should be blacklisted by default. Failure to blacklist the module will cause unneeded troubleshooting and people will blame linux desktop is not ready for major usage. I believe a lot of other usb related bug such as wifi disabled, bluetooth disabled, etc, was caused by this agressive power management for usb ports. Please see my config file attached, and apply it to the default config. -- System Information: Debian Release: stretch/sid APT prefers testing APT policy: (500, 'testing') Architecture: i386 (i686) Kernel: Linux 4.3.0-1-686 (SMP w/1 CPU core) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages laptop-mode-tools depends on: ii init-system-helpers 1.24 ii lsb-base 9.20150917 ii psmisc 22.21-2.1 ii util-linux 2.27.1-1 Versions of packages laptop-mode-tools recommends: pn ethtool <none> ii hdparm 9.43-2 ii net-tools 1.60+git20150829.73cef8a-2 pn python-qt4 <none> pn sdparm <none> ii udev 228-2+b1 ii wireless-tools 30~pre9-8 Versions of packages laptop-mode-tools suggests: ii acpid 1:2.0.25-1 -- Configuration Files: /etc/laptop-mode/conf.d/runtime-pm.conf changed: DEBUG=0 CONTROL_RUNTIME_AUTOSUSPEND=1 AUTOSUSPEND_USE_WHITELIST=0 AUTOSUSPEND_RUNTIME_DEVID_BLACKLIST="" AUTOSUSPEND_RUNTIME_DEVTYPE_BLACKLIST="usbhid psmouse" AUTOSUSPEND_RUNTIME_DEVID_WHITELIST="" AUTOSUSPEND_RUNTIME_DEVTYPE_WHITELIST="" BATT_SUSPEND_RUNTIME=1 LM_AC_SUSPEND_RUNTIME=1 NOLM_AC_SUSPEND_RUNTIME=1 AUTOSUSPEND_TIMEOUT=2 -- no debconf information
