I'm completely new to Ubuntu. I installed version 18.04 in dual boot with grub.

Problem

I've been having problems logging back after it's been asleep. When I open the lid and get to the the login screen (user choice), most of the times the trackpad and keyboard do not respond. When this happens, I cannot click on my user name and log in, can't even get to the password prompt. I can't do anything. Only thing I can do is a manual restart.

I've been troubleshooting the problem for a little while now. I have tried solutions found here, here, here, here, here. None work, the problem still occurs.

Solutions tried

  • Setting my grub file to

    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"

    messes up the resolution and then I can't change it.

  • Any other combination for GRUB_CMDLINE_LINUX_DEFAULT as stated in the previous links

  • Also, while looking at other threads, I have found that i'm supposed to be able to switch between consoles and the GUI when pressing CTRL + ALT + Fx. When I press CTRL + ALT + F1, it takes me back to the login screen where I can't enter anything! Trackpad and keyboard do not work at this point (nor any combination of CTRL + ALT + Fx). I have to do a manual restart. I believe this is related to the problem I have after the computer wakes from sleep.

  • I have also updated the kernel from 4.15 (i think) to 4.20.15 without any luck.

Any help would be appreciated. Thanks.

Specs

My laptop is an ASUS UX360CA with touchscreen. I don't know if the fact that the screen can change orientation based on how the laptop is placed has an impact but that setting is locked (off) anyway.

    Did you a clean install? Have you done update, upgrade, dist-upgrade after install properly? Did you install gdb3 Gnome desktop? You said that trackpad and Keyboard do not respond. Please go to settings and check the status of those peripheral devices. – Marmayogi Mar 28 '19 at 02:21
  • Please do one experiment. Go to settings and privacy and disable screen lock. Your laptop won't go to sleep. Verify @mikibok, this has any impact on login. – Marmayogi Mar 28 '19 at 02:28
  • How to reach peripheral devices? Go to settings, devices and you will see keyboard, Mouse & Touchpad along with others. – Marmayogi Mar 28 '19 at 02:32
  • You said that your laptop has dual-boot. Did you observe any problems to login Windows-10? Could you access BIOS setup screen by pressing del key? Did you see the presence of two boot loaders (one for windows and the other for Ubuntu)? Did you set default boot loader on your GRUB menu? What is your default Boot loader at present in your GRUB menu? – Marmayogi Mar 28 '19 at 02:37
  • In response to your comments @Marmayogi. The status of the trackpad and keyboard are fine in the settings. However, I cannot check this when the problem occurs. I have done update, upgrade without any changes. I will try dist-upgrade. I do have gdm3. I also tried sudo dpkg-reconfigure gdm3 without any luck. The problem does not occur when I am on Windows. There are two boot loads and by default it is on GRUB 2.02. I will also try to disable the screen lock. If all else fails, I will try a clean install. Thanks for your help! – mikibok Apr 02 '19 at 00:15
