Problems and Solutions for Ubuntu 16.04 LTS on ASUS ROG GL502VS Laptop
Nouveau does not appear to support Pascal cards right now, so you should use the proprietary NVIDIA driver, available from the Additional Drivers applet.
Once you have NVIDIA's driver installed, you may notice some color banding. The driver does not seem to detect the bpc of the panel properly, so you will need to set this yourself.
- Generate xorg.conf.
- Add this line under the
Screensection of the config to turn on dithering:
Option "FlatPanelProperties" "Dithering = Enabled"
Plymouth looks like it's running at 640x480. To increase the resolution,
follow this guide, but ignore the step
for installing v86d. You can set the resolution to
1920x1080. Note that
the splash may cut to black after a bit, with the dots being redrawn. No
idea why that happens, and there doesn't appear to be an easy fix.
The keyboard on the laptop is a USB HID keyboard, and sends its own
scancodes for hotkeys instead of going through ACPI, where the
would have handled it. This will require you to compile your own driver.
Download the source for the current version of your kernel (probably from here), and apply these patches:
Unmarked on the keyboard are the camera key (Fn+V), Splendid Utilities
key (Fn+C, mapped to
KEY_PROG2), and Power4Gear Hybrid key (Fn+Space,
KEY_PROG3, but doesn't actually work on this particular model).
The ROG key is mapped to
After you patch things up, build the module (see https://askubuntu.com/a/515408).
Copy the module to its proper directory in
sudo depmod -a,
and rebuild your initrd (
sudo update-initramfs -u).
Display Off Hotkey
After you get the hotkey driver installed, you need to add a script for
Fn+F7 to work. Follow the instructions here,
video/displayoff DOFF 00000089 00000000 for the event line. (You
may need to use
acpi_listen to find the actual event, if the above does
Screen doesn't turn on after it turns off
Update: appears to be fixed as of driver 375.26.
This is a known issue in the NVIDIA driver. See here for the thread. For now, you'll have to switch between one of the ttys (Ctrl-Alt-F1) and X.Org (Ctrl-Alt-F6) to get the screen to turn back on.
There are huge black borders around windows after resume
Also a driver bug. Do the same thing as above to reset things.
Airplane Mode LED lights when everything is on
This is a bug in the ACPI DSDT. We're waiting for the Linux devs to sort out what they want to call the airplane mode button before efforts to get the light to behave properly goes anywhere.
