Hello @kaihengfeng,
I have installed and tried your new kernel. It broke the nvidia 390.67
driver again, spamming dmesg with PKCS#7 signature not signed with a
trusted key.
Fixed the dmesg spam related to ELAN1200, however:
- Touchpad was difficult to use
- Cursor did not move smoothly anymore at all
- It appeared as though the touchpad had latency
- The touchpad disconnected a bit but managed to reconnect. (Intermittent
failures of less than
a second)
Thanks again for your efforts! Hopefully we can fix this.
