Fresh install of Deb 10. ATI RADEON 3000 on board GPU I installed this with a really cheap/small AOC monitor via a VGA connect. I do not know if this had anything to do with my problem.
I connected the PC to a TCL ROKU UHD TV via HDMI cable. I logged in and started GNOME.
The resolution was like it was on the tiny console I did the install from.
When I do xrandr : 720x400 0.00+ only is displayed.
I have read, it feels like, every blog in this solar system. Tried all of the suggestions.
I did go to GRUB command mode and listed all display capabilities and they were all in the output. I checked the driver level. Manually added another resolution and attempted to switch to it. It failed with "Max level is 720x400 0.00" I also get the famous "xrandr: Failed to get size of gamma for output default" message.
Any assistance would be greatly appreciated. Best regards, Michael:D
