[SOLVED] Issues with external monitor

Post by yangyang200 »

(I'm not a native English speaker, so please correct me if I have any grammatical/spelling issues)

I recently installed Linux Mint 20 Cinnamon on my Dell G3 15 3590. I also have an external monitor connected to it via HDMI (Dell U2414H), the monitor worked pretty well under Windows 10. Initially, the monitor sometimes display the system (but won't respond to clicks), sometimes nothing is shown except for the mouse pointer. After installing the recommended driver for the bundled graphics card (GTX 1660 Ti Mobile), the monitor is no longer recognized.

Thank you for your help.

According to that, you only thought you installed it.

In particular, see Solving freezes during the boot sequence. You need to boot with the nomodeset option then install the nVidia driver.
It's pronounced kad-eye-cha, not kada-itcha.

Thank you so much for your help. I followed the instructions above and booted with the nomodest option and tried to install the driver, after restarting the system information is still the same as before. Am I installing the drivers the wrong way? I tried to use the bundled Driver Manager application for that. Here's a screenshot:

Verify what you typed because that's not the same as nomodeset. If you did type it correctly, recheck the driver after rebooting with inxi -G.

If that still doesn't work, I'm afraid you'll have to wait for someone else to assist you as it's gone above my pay grade :)

Ha, sorry for that! I corrected the spelling and here's the output of the command:

Code: Select all

Graphics:
  Device-1: Intel UHD Graphics 630 driver: i915 v: kernel 
  Device-2: NVIDIA TU116M [GeForce GTX 1660 Ti Mobile] driver: N/A

Guess I'll just wait for someone else then. Thank you for your help!

No worries. I just noticed that in your original inxi output, you're booted in EFI mode. You may want to check your BIOS settings and make sure that both secure boot and fast boot are disabled. If they're not, turning them off then restarting with nomodeset, and reinstalling the nVidia driver followed by a normal boot without nomodeset might be the way to go.

For some reason disabling Secure Boot still didn't work. I couldn't find Fast Boot in the BIOS settings.

For more context, the nomodeset option will be changed to quiet splash every time I reboot the computer. After rebooting, it always shows "Not using hardware acceleration, please check Driver Manager", however in the Driver Manager the driver appears to have been installed.
