Wrong display resolution after attempted manual Nvidia driver update

eco_bach · 10-07-2017, 03:28 PM

Made the mistake (which I will NEVER do again!) of trying to manually update my NVIDIA driver on Ubuntu Mate 16.04 LTS.
Anyways the update failed and now I am left with a screen resolution that is wrong (too low resolution)

How do I restore the proper resolution? The attached shows I am still running the older 384 driver.
Any kind Linux gurus able to help me thru this?

This is my xorg file

Update
I tried editing my xorg by adding
Modes "2560x1440"
but after rebooting my resolution is higher but only 1024x768!

2nd Update
Not sure if its related but if I choose
System>Preferences>Hardware>NVIDIA XServer Settings
I see
You do not appear to be using the NVIDIA X Driver...

3rd Update
I'm attaching my NVIDIA install log for completeness

Guessing you installed the nvidia driver from the nvidia web site?

Yes, manual install. Official driver from NVIDIA, I thought what could happen? Guess I was wrong.

and then simply use Software & Updates to reinstall the latest Ubuntu compatible Binary driver ? (384.90)

I would remove the nvida driver you downloaded. I think it includes a removal script? Yes, then use official means to install the driver.

Thanks. Just a bit confused how to run the uninstaller. All I see is NVIDIA-Linux-x86_64-387.12.run
Is there a default 'uninstall' command or should there be an uninstall option if I try and run the above installer again?

eco_bach · 10-07-2017, 09:47 PM

Answering my own question
Did a sudo sh

./NVIDIA-Linux-x86_64-387.12.run -uninstall

And then used Software & Updates to reinstall my previous working driver
Rebooted and good to go

sevendogsbsd · 10-07-2017, 09:49 PM

Awesome!

eco_bach · 10-07-2017, 09:54 PM

only remaining issue is that I have lost my custom fan settings in NVIDIA XServer software. DOn't recall if this has something to do with Coolbits or??
