In an attempt to set up an external monitor, I have screwed up my Ubuntu 16.04 Dell laptop. Seems like I messed up the graphic drivers and now I am stuck at the “The system is running in low-graphics mode” screen with no option to proceed after booting.
I can only run commands from a terminal by pressing CTRL+ALT+F1.
Output of lspci command says VGA compatible controller: Advanced Micro Devices. Inc [AMD/ATI] Mars [Radeon HD 8730] (rev ff)
Here is what I have tried so far:
- I tried to fix the issue by following this step-by-step guide. However, no luck. Especially,
sudo apt-get install fglrxyield no such package. - I also followed the official guidelines by AMD. No luck here as well. No noticeable errors as such. But, the error message "system is running in low-graphics mode” still persists after reboot.
- As a last resort, I tried to upgrade to 18.04 LTS through a bootable flash USB. To my bad luck, there is no option to upgrade, and it shows only install alongside or erase/reinstall.
I have spent almost 8 hours trying to debug now, and all my trials are getting useless and redundant. Any help to guide me in the right direction would be much appreciated. What am I missing basically?
