I’m running manjaro on my XPS 15 which has hybrid GPU. I recently managed to get it all setup and running using
optimus-manager but after a while running in
nvidia) mode (using Intel GPU as default, while allowing to use the Nvidia GPU for prime offloading) my system runs into problems when waking up from sleep. I use hybrid-sleep to ensure that if the laptop runs out of power, I can still restore it’s state. How ever in the
hybrid (and also
nvidia) mode, when I wake the system up it restores the screen (I can see what ever was on the screen before it went to sleep) and the system hangs. There’s no cursor, it doesn’t respond to any keys except the power button. Leaving it for a bit just makes the fans ramp up and pressing the power button causes the screen to turn off while the fans go on for a minute or two before the system shuts down. This does not happen when running the Intel GPU only.
I went through my
journalctl -b1 after rebooting and found this:
Jun 16 20:04:21 malus kernel: EXT4-fs (nvme0n1p1): Cannot change data mode on remount Jun 16 20:04:21 malus systemd-remount-fs: mount: /: mount point not mounted or bad option. Jun 16 20:04:21 malus systemd-remount-fs: /usr/bin/mount for / exited with exit status 32. Jun 16 20:04:21 malus systemd: systemd-remount-fs.service: Main process exited, code=exited, status=1/FAILURE Jun 16 20:04:21 malus systemd: systemd-remount-fs.service: Failed with result 'exit-code'. Jun 16 20:04:21 malus systemd: Failed to start Remount Root and Kernel File Systems.
But I have no idea what could cause this, as in Intel mode this doesn’t occur.

I’m not sure what other information might be of use.
