I got a new Dell M3800 laptop and I use gentoo+fvwm
In /etc/acpi/lid.sh , I use
echo -n mem >/sys/power/state
to let the system sleep when the lid is closed.
The problem is when I open the lid, I got a white screen. I need to do
ctrl+alt+F1 to go the console then ctrl+alt+F7 to go back to fvwm to eliminate the white screen.
I check the demesg and I found the following errors
[ 2779.734885] pciehp 0000:00:1c.0:pcie04: Link Training Error occurs
[ 2779.734886] pciehp 0000:00:1c.0:pcie04: Failed to check link status
[ 2779.734986] dpm_run_callback(): pnp_bus_resume+0x0/0xa0 returns -19

[ 2779.782972] tpm_tis 00:0c: TPM is disabled/deactivated (0x6)
Does anyone have any ideas how to solve the problems. Thanks.
