I installed kali alongside ubuntu but I formatted the kali drive.
I reinstalled grub using the following command:
grub-install /dev/sda
Now when I boot, I get No such partition error.
I did the following steps in grub rescue console:
set prefix=(hd0,2)/boot/grub
set root=(hd0,2)
insmod normal
normal
After that it successfully booted into the Ubuntu installation but I have to do it every time device boots up.
How to fix this problem permanently?
I have Ubuntu 19.10 and installed NVIDIA proprietary drivers.
When I switch to Intel graphics, I can use fractional scaling feature. But when I switch to NVIDIA using prime-select command, display scale returns to 100%. Is it possible to have fractional scaling when using high-performance NVIDIA graphics?
Edit:
Laptop Model: Acer Aspire 7 A715-71G-71Y3
NVIDIA Card: GTX 1050 Ti Mobile
NVIDIA Driver: nvidia-driver-435 (proprietary, tested)
I also need to state that switch happens when I reboot the machine (NVIDIA settings app tells me to restart the device after changing prime settings).
Also, when I enable fractional scaling again, and choose 125%, it scales 200% instead of 125%.
I have installed Nvidia proprietary driver on Ubuntu 19.10.
In the Prime Profiles section, there are three options:
* NVIDIA (Performance Mode)
* NVIDIA On-Demand
* Intel (Power Saving Mode)
First and last options are quite obvious, But I don't know how the second option works. How it detects which application needs NVIDIA driver and which doesn't?
My laptop has Intel (integrated) and Nvidia graphic cards. I have installed bumblebee. But laptop is still getting too hot. How can I check if I have done everything correctly?
