Fixing suspend with Linux on TUXEDO InfinityBook Pro 15
I had a problem with my laptop waking up from suspend after a couple of seconds. Here is how I fixed the problem.
I'm running Fedora Rawhide Cosmic. But this will be the same for all Fedora (and most other Linux distroes).
Add acpi.ec_no_wakeup=1 to the line that starts with: GRUB_CMDLINE_LINUX= in the file /etc/default/grub. Then run grub2-mkconfig -o /boot/grub2/grub.cfg then reboot.
Then new file should look like this:
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="rhgb quiet acpi.ec_no_wakeup=1"
GRUB_DISABLE_RECOVERY="true"
GRUB_ENABLE_BLSCFG=true
Reboot your system, and the problem should be fixed.
