I am using Dell G15 Laptop, with RTX 3050. It was working very smoothly. Then I have tried to install cuda to use graphic card. But after that, my laptop screen went completely blank.
So, I thought to uninstall drivers and reinstall them.
sudo apt-get remove nvidia*
sudo apt autoremove
Then I run this commands:
sudo apt-get install dkms build-essential linux-headers-$(uname -r)
After that: sudo update-initramfs -u
And then finally sudo apt-get install nvidia-VERSION (Here I am using 525)
So after all these, I started getting errors on e2fsck :cannot continue, aborting.
Then I tried few related commands and in ubuntu recovery mode and finally somehow, using reboot from recovery mode, I am able to open my ubuntu system now.
But the issue is its lagging, chrome doesnt open up fast, its smoothness gone completely. And even I reboot now, it takes multiple attempts to start the laptop from recovery mode. Normally ubuntu is still not starting.
