Hi folks... hope someone can help...

Recently bought a brand new laptop for my neighbour, he has been using Trisquel for years and wanted Trisquel installed onto his new one.

Trisquel 8, installed no problems at all, installed the updates etc restart the laptop and loads up to a black screen, I know its at the password login screen as I can hear the water droplet, and before I could hear orca (before I killed that!) I need to turn it off by holding the power button. Turn it back on screens working and I can see the login screen.

I maybe way off but I'm sure its a graphics driver issue, its stuck on 1920 x 1080 and I cant change it.

as you can see

xrandr: Failed to get size of gamma for output default

1920x1080 0.00*

I've been at it for days!

Any help would be greatly appreciated!

Drivers are in the kernel. That is why I would try a newer kernel. Installing the package "linux-image-generic-hwe-8.0" (in Trisquel 8's repository) will give you version 4.15. provides instructions to get even newer Linux-libre kernels, such as version 5.4 or 5.6. Reboot after installing the newer kernel.

Thanks for that link. I've bookmarked that guide for future use.
