Dell Inspiron 7537 - Resume from sleep causes various dmesg errors

Question

Hi,
I'm getting various acpi and intel video driver errors upon resume from sleep. The system does come up and I haven't found any functional problems that this is causing. I think the acpi errors may just be causing some devices to drain more power than is necessary. I have tried various live CD's from Ubuntu, Sabayon, and Fedora and they all have these same symptoms. Can anyone help with this, particularly anyone with the same laptop model who may have fixed these issues?
Thanks,
D

Answer 1

I also bought a Dell Inspiron 15 7537 and I had the same problem as OP, but on Fedora 21 64-bit with Gnome 3.14. I haven't tried any other distros or DEs. However, both Arch and Fedora run systemd, so I think my solution work the same on both systems. I fixed it by doing the following steps:
1. Create a script that reloads the kernel module hid_multitouch.
$ sudo mkdir /opt/touchscreen-fix
$ cd /opt/touchscreen-fix
$ echo '#!/bin/sh
/sbin/rmmod hid_multitouch && /sbin/modprobe hid_multitouch' | sudo tee resume.sh
$ sudo chmod +x resume.sh
Executing this script after a resume will make the touchscreen work again. However, it will of course not run automatically after a resume.
2. Schedule the script to run after resume.
Create the systemd service file:
$ echo '[Unit]
Description=Fix touchscreen after resume
After=suspend.target
[Service]
Type=simple
ExecStart=/opt/touchscreen-fix/resume.sh
[Install]
WantedBy=suspend.target' | sudo tee /etc/systemd/system/touchscreen-fix.service
Enable it:
$ sudo systemctl daemon-reload
$ sudo systemctl enable touchscreen-fix
Done! And that's all! I'm not sure if you also might need to restart the computer for it to work.
To accomplish this I used the following resources:
