我最近買了一個聯想 Ideapad Flex 5。我立即刪除了 Windows 11 Home 並安裝了 Ubuntu 23.04。唯一的問題：觸控板不工作。Ubuntu 甚至無法辨識觸控板，從下面的輸出可以看出lsusb：
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 004: ID 0bda:4853 Realtek Semiconductor Corp. Bluetooth Radio
Bus 003 Device 003: ID 1c7a:0576 LighTuning Technology Inc. EgisTec EH576
Bus 003 Device 002: ID 093a:2510 Pixart Imaging, Inc. Optical Mouse
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 002: ID 30c9:0053 Luxvisions Innotech Limited Integrated Camera
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
我嘗試過其他Linux發行版；同樣的問題。不過，觸控板在 BIOS 選單中運作正常，所以我知道這不是硬體問題。我上網到處找過，但找不到任何東西。

這個問題是重複的但沒有答案。請有人幫助我，我真的需要這個才能工作。輸出libinput list-devices：

我sudo dmesg | grep modprobe跑完之後sudo modprobe i2c-hid-acpi得到了這個：

答案1
對於 Lenovo Ideapad Flex 5 14ARE05，沒有已知的解決方法，但我會嘗試根據中的描述添加到核心命令列“i8042.reset=1”https://bugs.launchpad.net/ubuntu/+source/linux-signed-hwe-5.8/+bug/1912880暫停時強制關機，恢復觸控板（儘管我在Lenovo Thinkpad Yoga S1 上使用此類i8042 重置來修復相反的問題，即暫停時強制關機後沒有鍵盤/觸控板，但值得一試。我從那時起就使用過此技巧據報道）。
您可能還想嘗試“i8042.nopnp=1”，如上述報告中的 dmesg 日誌所示：
[ 0.602905] i8042: PNP: PS/2 appears to have AUX port disabled, if this is incorrect please boot with i8042.nopnp
i8042.nomux=1那你也可以嘗試一下i8042.kbreset=1
您可能還想向 Linux 核心 ML 或 bugzilla 報告該錯誤https://bugzilla.kernel.org/。您可能想要發布您的 dmesg 輸出或至少：
sudo dmesg|grep -E "PS\/2|ACPI|hid|i8042"
對於聯想 IdeaPad 5 15are05，IdeaPad 5 15are05 - elan 觸控板在 20.04 和 18.04 上皆無法運作
modprobe i2c_hid echo "i2c-ELAN0001:00" > /sys/bus/i2c/drivers/elants_i2c/unbind echo "i2c-ELAN0001:00" > /sys/bus/i2c/drivers/i2c_hid/
initcall_blacklist=elants_i2c_driver_initbind （/etc/default/grub 中的GRUB_CMDLINE_LINUX="" （2020 可能已在上游修復）
對於聯想 IdeaPad 3 14IIL05，https://bugs.launchpad.net/ubuntu/+source/linux-signed-hwe/+bug/1880172/comments/53， 那是：
將以下參數加入 GRUB_CMDLINE_LINUX_DEFAULT。
「i8042.nopnp=1 pci=nocrs」（2020）
@SO_32 你可能想嘗試不使用pci=nocrs. i8042 參數不應影響 wifi 設備本身。
