Hi Aaron,
I did:
$ sudo dpkg -i linux-{image,headers}-4.20.0-rc3+_4.20.0-rc3+-6_amd64.deb
# edit /etc/default/grub so it now reads:
GRUB_CMDLINE_LINUX_DEFAULT="acpi_osi=! acpi_osi='Windows 2009'
modprobe.blacklist=nouveau rmi_core.debug_flags=0x7"
$ sudo update-grub
$ sudo /sbin/shutdown now
# reboot into kernel 4.20
# touchpad now more responsive - it picks up lighter and faster touches as
clicks.
# close lid to suspend. on first two wakeups, touchpad worked
# on third wakeup, touchpad didn't work. then:
$ cat /proc/interrupts | grep rmi > rmi_irq.log
# move finger around on touchpad for several seconds, even though mouse
pointer didn't move
$ cat /proc/interrupts | grep rmi >> rmi_irq.log
# rmi_irq.log is empty
$ journalctl -b 0 -k > journalctl.log
# just for curiosity, close lid again, wait 10 seconds, reopen. Still,
mousepad is unresponsive.
# Then, without warning, laptop goes into sleep mode (with lid still open. I
press the button to resume. Screen blinks about five times, and finally wakes
up. Now, mousepad works.
$ journalctl -b 0 -k > journalctl.after_blink.log
$ wc -l journalctl.*
1735 journalctl.after_blink.log
1586 journalctl.log
Have attached journalctl.after_blink.log
Thanks in advance for any information you could provide!
