I have been trying to get Ubuntu work on my laptop (dual boot alongside Windows 10) for quite a while now. It all started with me installing Ubuntu 16.04. It worked just fine, but I wasn't able to adjust my keyboard backlight's brightness. It glowed to its full extent, draining my battery in an hour and a half. All the solutions offered on the internet did not work, including updating to a new kernel version, leaving me frustrated and disappointed. I waited until 17.04, but couldn't install due to it crashing when Try Ubuntu or Install Ubuntu is selected (Errors that showed up are listed at the end). Waited for 17.10, same problem, no hope. Now it's 18.04 and I'm still facing installation issues with Ubuntu.
Here's what happened.
I burned the image of Ubuntu 18.04 to my USB drive using Rufus on Windows. Shut my PC down, plugged in the USB, changed UEFI Boot order, and I got the "Try Ubuntu, Install Ubuntu ... " screen. When I select either of those (Try or Install) the splash screen for Ubuntu appears, I see the red dots popping in and out and the system crashes. One fix I found was to change
quiet splash to
nomodeset in the GRUB options. Then Try Ubuntu worked, and I installed Ubuntu 18.04.
The problem now was that I wasn't able to change my brightness. I didn't see any brightness adjustment slider on the top, and neither the function key for brightness (Fn+F5, F6) worked. After I restarted upon installation, I tried to switch to nVidia proprietary drivers, hoping it would fix the brightness problem ( In Software & Updates -> Additional Drivers). That made it even worse. The log that is shown during Ubuntu's boot crashes and my laptop's fan begins to run at crazy speeds. There was no hard disk access when that happens (the hard-disk access light stops glowing). I had to hard press power button to force shutdown. I tried Bumblebee, same problem. I tried uninstalling nVidia drivers on recovery, but it still didn't fix my problem.
One thing that quite often popped up while booting Ubuntu (17.10, 18.04) was these two errors:
- TSC_DEADLINE disabled due to errata. Upgrade microcode firmware to 0x52.
- ACPI Error : AE_ALREADY_EXISTS
The above situation (Ubuntu crashing after Nvidia driver install) is rectified when I set
acpi=off in GRUB. But this renders my touchpad unable to use, and I could not shut down my system without having to press the power button. The brightness adjustment slider wasn't there either.
My Laptop's Configuration:
- CPU: Intel i5 7300HQ
- RAM: 8 GB
- GPU: nVidia GeForce GTX 1050 (2GB GDDR5 VRAM)
I was running the latest BIOS provided by ASUS the whole time.
