I have Asus K50-IE old laptop. First time I installed it without any problems, and also I did all the updates, and it worked like a charm, even with the Livepatch option. Before I had Windows 7 x64 os installed.
Then I reinstalled it once more (actually many more in different combinations), with the erase option, and put all the updates, and now I can not shut down or reboot properly. I repeated the process on a virtual machine, but there everything works just fine.
So far I tried
sudo nano /etc/default/grub
and then replace
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" with GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force", which it almost works. It didn't power off completely.
I tried also replace with GRUB_CMDLINE_LINUX_DEFAULT="quiet splash apm power_off"
and finally I make it work with :
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"
with
sudo update-grub
which resolved the shut down, but it made the resolution smaller by half.
Then I resolved the resolution by running ubuntu-drivers devices and installed another driver for the video, and also append video=hyperv_fb:1366×768 to Grub line, resulting in GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset video=hyperv_fb:1366×768".
I even changed the time ammount to shut down, by entering somewhere in /etc/systemd/system.conf and then change DefaultTimeoutStopSec=5.
But now I can not fix the reboot mode also. And I am sick and tired to look in each kernel settings. I am new to Ubuntu Linux.
Do you have an easier solution ? Some general that works every time ?
Before I didn't need to install drivers for ubuntu, so I guess I missing something.
